Description

  The present invention relates to a medical removal tool, and more particularly to a medical removal tool used for removing a connector attached to a tracheostomy tube or the like.

  For example, in the case of respiratory failure due to illness or surgery, a ventilator is used for the purpose of supplying oxygen to the human body. When supplying oxygen to the human body with a ventilator, oxygen is supplied to the trachea from the mouth, or the trachea (neck) is incised, and oxygen is supplied from the incised portion. When supplying oxygen from the mouth to the trachea, a tracheal tube is generally used. When oxygen is supplied from the incised portion, a tracheostomy tube is used. These are determined in consideration of the degree of urgency, the period for attaching the tube, and the like.

  The tracheal tube or tracheostomy tube inserted into the human body is communicated with a ventilator which is a device for sending oxygen through various tubes (hereinafter referred to as a ventilator-side tube). More specifically, the tracheal tube or tracheostomy tube is provided with a 15 mm connector defined by international standards. By attaching the ventilator side tube connector to the 15 mm connector, the tracheal tube or tracheostomy tube is provided. The tube is in communication with a ventilator that delivers oxygen.

  Here, the connector of the 15 mm connector and the ventilator side tube is formed in a taper shape, and friction is utilized by pushing the connector of the ventilator side tube serving as the female side into the 15 mm connector serving as the male side. The two connectors are engaged. These connectors are fitted with a certain degree of strength by a practitioner (for example, a doctor, a nurse, etc.) in order to prevent a drop-off accident such as the patient coming off when the patient moves. Here, when it is necessary to remove both connectors, it is desirable to be able to remove them quickly considering the burden on the patient. Moreover, if it is difficult to remove both connectors, there is a possibility that the work burden of doctors, nurses, etc. will increase.

  Therefore, U-shaped removal tools that are used to remove both connectors have been proposed (see, for example, Patent Document 1 and Non-Patent Document 1). In Patent Literature 1 and Non-Patent Literature 1, as shown in FIG. 18, the distal ends of the two rod-shaped members formed on the removal tool are tapered. That is, it has a shape in which the thickness increases from the tip side to the opposite side. For this reason, when the rod-shaped member of the removal tool is inserted between the two connectors from the distal end side, the thickened portion comes into contact with the ventilator-side connector. When the removal tool is further inserted, the ventilator side connector is pushed out to the side opposite to the side where the 15 mm connector is provided, and the ventilator side connector is removed from the 15 mm connector.

Japanese Patent Laying-Open No. 2005-312491 (see, for example, abstract, paragraph [0005] and FIG. 1)

RESPIRATORY CARE / APRIL 2005 VOL 50 NO 4 (for example, see FIG. 3)

  Since the technique described in Patent Document 1 and Non-Patent Document 1 inserts a removal tool between both connectors from one direction, there is a possibility that accidental tube removal may occur due to a mistake in adjusting force.

  Further, in the techniques described in Patent Document 1 and Non-Patent Document 1, when the removal tool is inserted into both connectors, the distal end side of the rod-shaped member of the removal tool comes into contact with or pierces the human body, thereby removing the patient tissue. There is a possibility of hurting. In particular, when removing the 15 mm connector of the tracheostomy tube and the connector on the ventilator side, the tip of the removal tool comes into contact with a part such as the face or the neck because the 15 mm connector is attached near the neck. , You may get stuck.

  Further, in the techniques described in Patent Document 1 and Non-Patent Document 1, depending on the combination of both connectors, the removal tool is inserted to the place where the height of the removal portion is not enough and the removal portion has the largest thickness. However, the ventilator-side connector may not be removed from the 15 mm connector.

  As described above, in the techniques described in Patent Document 1 and Non-Patent Document 1, there are concerns that accidental extubation, damage to patient tissue, and detachment depending on the combination of both connectors are lacking, and there is a problem in that it is not convenient.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a removal tool with improved convenience.

  The medical removal tool of the present invention is a medical removal tool used to remove the second connector portion from the first connector portion, and is connected to a bendable bending portion and one end of the bending portion. The first gripping portion formed, the second gripping portion connected to the other end of the bent portion, and the first gripping portion formed on the opposite side to the side connected to the bent portion of the first gripping portion. 1 connector removal portion, a second connector removal portion formed on the side opposite to the side connected to the bent portion of the second gripping portion, and a first connector formed on the first connector removal portion. A sandwiching portion and a second sandwiching portion formed on the second connector removal portion and facing the first sandwiching portion are included.

  According to the medical removal tool of the present invention, since it has the above configuration, the convenience can be improved.

Embodiment.
FIG. 1 is an explanatory diagram of a generally used tracheostomy tube 1. FIG. 2 is an explanatory view showing a state in which the tracheostomy tube 1 shown in FIG. 1 is attached to the human body. FIG. 3 is an explanatory diagram of a connector or the like attached to the tracheostomy tube 1 shown in FIGS. 1 and 2. 1A is an overall perspective view of the tracheostomy tube 1, and FIG. 1B is a cross-sectional view taken along line AA of FIG. 1A. The tracheostomy tube 1 and the like will be described with reference to FIGS.

[Tracheostomy tube 1]
The tracheostomy tube 1 includes a vent tube 2 provided with various lumens, a cuff 4 that expands when pressurized, a suction lumen 13 and a suction lumen tube 12 that are used for discharging sputum, and the like. For fixing the tracheostomy tube 1 to the human body, the small cuff inflation lumen 5 and the small cuff tube 10 used for pressurization 4, the connector part 6 connected to the connector part 50 on the ventilator side, and And a fixture 7 to be used.

  The vent tube 2 is a dog-shaped luminal body that is curved with a slightly large curvature of, for example, about 90 °. The lumen of the lumen body is provided with an airway securing lumen 2a, a suction lumen 13, and a cuff inflation small lumen 5. The vent tube 2 is provided with a connector portion 6 on one end side and a cuff 4 on the other end side. As shown in FIG. 2, the vent tube 2 is inserted into the trachea inside the patient's body from the incised neck.

  The cuff 4 is provided so as to cover the outer periphery of one end side of the vent tube 2. The cuff 4 has a function of regulating the movement of the vent tube 2 so that the vent tube 2 inserted into the trachea, for example, does not move within the trachea. The cuff 4 is hollow, for example. The cuff 4 can be pressurized and depressurized by utilizing the cuff inflation small lumen 5 provided in the tube wall portion of the vent tube 2. When the cuff 4 is pressurized and decompressed, it expands and contracts as appropriate. As shown in FIG. 2, when the cuff 4 is inflated, the outer periphery abuts against the airway. Thereby, the air and oxygen which enter the trachea by the vent tube 2 can be sent to the lungs without any leakage. In addition, secretions from the upper airway are prevented from sagging into the lower airway. Further, the vent tube 2 can be held so as not to move in the airway.

  The suction lumen tube 12 sucks solids such as fluids and food in the trachea of the human body, which are stored around the cuff 4 when the tracheostomy tube 1 is attached, and puts it outside the human body. It is used to discharge. Solids such as fluid and food sucked into the suction lumen 13 are discharged to the outside of the human body through the suction lumen tube 12. A suction opening 13 a is formed on the end side of the suction lumen 13. The suction opening 13 a is formed on the outer surface of the vent tube 2 so that the suction lumen 13 communicates with the outside of the vent tube 2.

  The cuff small tube 10 communicates with the cuff inflation small lumen 5 and is used to pressurize or depressurize the hollow portion of the cuff 4. The cuff inflation small lumen 5 is a lumen smaller in size than the suction lumen 13. This is because the suction lumen 13 needs to be highly suckable. For this reason, the lumen of the vent tube 2 is biased toward the small lumen 5 for cuff inflation, and the wall thickness on the side where the suction lumen 13 is formed is formed with the small lumen 5 for cuff inflation. Thicker than wall thickness on opposite side.

The connector part 6 is attached to one end side of the vent tube 2 and is attached to the connector part 50 on the ventilator side. The connector unit 50 is connected to a ventilator circuit component 51 that communicates with the ventilator. The connector part 6 is provided so as to be rotatable with respect to the vent tube 2. The connector part 6 is a so-called 15 mm connector defined in international standards. The connector part 6 is a cylindrical member. In more detail, the connector part 6 is a cylindrical member formed in a taper shape so that an outer diameter becomes small as it goes to the one end side from the other end side of the vent tube 2. Further, the connector portion 6 is formed with a flange 6a.
As shown in FIG. 3, the connector portion 6 is a male connector, while the ventilator-side connector portion 50 attached to the connector portion 6 is a female side. That is, a taper having a shape corresponding to the taper of the connector part 6 is formed inside the connector part 50 on the ventilator side. The connector part 50 on the ventilator side is fitted into the connector part 6 when the connector part 50 on the ventilator side is pushed into the connector part 6.

  The fixture 7 is provided on one end side of the vent tube 2 and on the cuff 4 side with respect to the connector portion 6. The fixture 7 includes a shaft portion 8 a extending from the connector portion 6, and an arm portion 8 b provided at a lower portion of the shaft portion 8 a and formed to extend to the left and right sides with respect to the vent tube 2. It is what. A hole 9 for attachment to a human body is provided on each end of the arm 8b in the longitudinal direction.

[Tracheal tube 1B]
FIG. 4 is an explanatory diagram of a commonly used tracheal tube 1B. FIG. 5 is an explanatory diagram of a connector to which the tracheal tube 1B shown in FIG. 4 is attached. With reference to FIG.4 and FIG.5, the tracheal tube 1B etc. are demonstrated before description of the removal tool 100 which concerns on this Embodiment.

  Since the tracheal tube 1B is inserted from the patient's mouth, the vent tube 2B is longer than the vent tube 2 of the tracheostomy tube 1 and is provided with various lumens, and a cuff 4B that expands when pressurized. It has a small cuff tube 10B and a connector part 6B connected to the connector part 50 on the ventilator side.

  The vent tube 2B is also a luminal body that is curved in the same manner as the vent tube 2. Although not shown, the lumen of the lumen body is provided with an airway securing lumen and a small lumen for cuff inflation. The vent tube 2B is provided with a connector portion 6B on one end side and a cuff 4B on the other end side. As shown in FIG. 5, the vent tube 2B is inserted into the human body from the patient's mouth. The cuff 4B, the small cuff tube 10B, and the connector portion 6B have the same functions as the cuff 4, the small cuff tube 10 and the connector portion 6 of the tracheostomy tube 1.

FIG. 5 shows an example in which oxygen gas (oxygen) is supplied using a tracheal tube 1B inserted into a patient's respiratory trachea. A bag B for allowing the patient to breathe and the tracheal tube 1B are connected via a hose C or the like. Then, an oxygen supply tube 52 is connected to an oxygen supply conduit 54 provided in the ventilator circuit constituting member 53 to supply high oxygen gas to the tracheal tube 1B.
A connector part 50 is connected to the connector part 6B, and a ventilator circuit component 53 is connected to the connector part 50. The ventilator circuit component 53 is branched and connected to the hose C and the oxygen supply conduit 54. The hose C is connected to the bag B.

  In the circuit shown in FIG. 5, the practitioner pushes the bag B by hand to cause the bag B to contract, thereby moving the oxygen gas to the patient side through the oxygen supply tube 52 to inhale the patient. Is expanded, and exhaled air is discharged through the bag B. A predetermined flow rate of oxygen is supplied to the oxygen supply tube 52 connected to the circuit, and the oxygen supplied from the oxygen supply tube 52 to the ventilator circuit component member 53 breathes together with inspiration during inspiration. It moves to the trachea, and when exhaling, it moves in the direction of the bag B together with the exhalation without moving to the patient side, and is released from the discharge port to the atmosphere. As a result, the pressure in the patient's trachea is not increased by the oxygen supplied from the oxygen supply tube 52.

Further, the length in the longitudinal direction of the first rear side clamping unit 103A and the second rear side clamping unit 103B may be, for example, about 1.8 (cm). However, it is not limited to these lengths.
For example, in a state in which no force is applied to the removal tool 100, the front end of the first front side clamping unit 102A and the front end of the second front side clamping unit 102B are separated from the outer diameter of the connector unit 6, and the first The length in the longitudinal direction may be set so that the front end of the rear holding portion 103 </ b> A and the front end of the second rear holding portion 103 </ b> B are separated from the outer diameter of the connector portion 6.

  In addition, as shown in FIG.6 (c), the front-end | tip detail is good for the 1st front side detail 102A2 to be an acute angle. Thereby, the first front side detail 102A2 can easily enter the connecting portion between the connector part 50 and the connector part 6 on the ventilator side, and the burden on the practitioner can be reduced. This will be described in detail with reference to FIG.

  In addition, the first front clamping unit 102A and the first rear clamping unit 103A correspond to the first clamping unit, and the second front clamping unit 102B and the second rear clamping unit 103B are the second clamping unit. It corresponds to.

(Rib portion 120)
The rib portion 120 is formed to reinforce the removal tool 100. By forming the rib portion 120 on the removal tool 100, when the practitioner loosens the force after closing the removal tool 100, the removal tool 100 is easily returned to the original state. The rib portion 120 is continuously formed on the inner surface of the first gripping portion 101A, the inner surface of the bent portion 111, and the inner surface of the second gripping portion 101B. The rib portion 120 is formed at the same height as the first connector removal portion 110A and the second connector removal portion 110B.

Fig.7 (a) is an outer side view, FIG.7 (b) is sectional drawing. In FIG. 7, the tracheostomy tube 1 is described as an example. However, since the connection between the connector portion 6B of the tracheal tube 1B and the connector portion 50 is substantially the same, description thereof is omitted.

  As shown in FIG. 7, the connector portion 6 is formed in a cylindrical shape, and is a male connector that can be fitted inside the ventilator-side connector portion 50. And the connector part 6 has the taper shape 60, and is formed so that an outer diameter may become small as it goes to the connector part 50 by the side of a respirator. On the other hand, the ventilator-side connector portion 50 is a female-side connector into which the connector portion 6 is inserted. The inside of the connector portion 50 is formed so as to correspond to the tapered shape 60 of the connector portion 6. That is, the connector part 50 has a tapered shape 61. Therefore, the connector part 6 and the connector part 50 are fitted by friction. The connector portion 6 is a first connector portion, and the ventilator-side connector portion 50 is a second connector portion.

[Description of operation]
FIG. 8 is an explanatory diagram showing a state in which the ventilator-side connector part 50 is removed from the connector part 6 of the tracheostomy tube 1 using the removal tool 100. In FIG. 8, the tracheostomy tube 1 is described as an example in the same manner as in FIG. 7, but the description is omitted because it is substantially the same in the tracheal tube 1B.
In the description of FIG. 8, the first front side clamping unit 102A and the second front side clamping unit 102B are illustrated, and the description of the first rear side clamping unit 103A and the second rear side clamping unit 103B is not described. Omitted for convenience.

  When removing the connector part 6 from the connector part 50, the practitioner attaches the first connector removal part 110A and the second connector removal part 110B to both connectors (6, 50) as shown in FIG. Match the connection position. More specifically, the practitioner matches the first connector removal portion 110A and the second connector removal portion 110B with the portion R of the connector portion 6 exposed from the connector portion 50 on the ventilator side. Then, the practitioner holds the exposed portion R between the first front clamping unit 102A and the first rear clamping unit 103A and between the second front clamping unit 102B and the second rear clamping unit. The connection positions are adjusted so as to enter each of the parts 103B. Here, the upper portion of the connector portion 6 is inserted into the female connector portion 50, but the portion of the connector portion 6 that is not inserted is an exposed portion R.

  Then, the practitioner closes the first gripping portion 101A and the second gripping portion 101B, and narrows the facing distance between the first connector removal portion 110A and the second connector removal portion 110B. As a result, as shown in FIG. 8B, the first connector removal portion 110A and the second connector removal portion 110B come into contact with each other and ride on the upper side of the second connector removal portion 110B. Here, the case where the first connector removal portion 110A rides on the second connector removal portion 110B has been described as an example, but the second connector removal portion 110B may ride on the first connector removal portion 110A. Good.

When the first connector detaching portion 110A rides on the second connector detaching portion 110B and the opposing distance between the first connector detaching portion 110A and the second connector detaching portion 110B is further reduced, the first connector detaching portion The upper surface of the first front taper 102A2 of 110A abuts on the ventilator-side connector portion 50 (see the abutting portion P in FIG. 8B).
In the contact portion P, the entire upper surface of the first front side detail 102A2 is not in contact with the lower surface of the connector part 50 on the ventilator side, but a part of the upper surface of the first front side detail 102A2. It is in contact with the lower surface of the connector part 50 on the ventilator side. That is, the lower surface of the connector 50 is flat, but the upper surface of the first front taper 102A2 is not parallel to the flat lower surface and is inclined, so that the upper surface of the first front taper 102A2 is inclined. A part of the contact portion comes into contact with the lower surface of the connector portion 50 on the ventilator side.
Here, the upward direction is described as indicating the direction from the connector part 6 side toward the connector part 50 side on the ventilator side. Conversely, the downward direction is described as indicating the direction from the connector part 50 side on the ventilator side toward the connector part 6 side. For this reason, the upper surfaces of the first connector removal portion 110A and the second connector removal portion 110B refer to the surface on the ventilator-side connector portion 50 side, and the first connector removal portion 110A and the second connector removal portion. The lower surface of 110B refers to the surface on the connector part 6 side.

  At this time, although not shown, the first rear holding portion 103A is also in contact with the second rear holding portion 103B and rides on the upper side of the second rear holding portion 103B. A part of the upper surface of the first rear holding portion 103A is in contact with the lower surface of the connector portion 50 on the ventilator side.

In addition, since a part of the upper surface of the first front side detail 102A2 and a part of the upper surface of the first rear holding part 103A are in contact with the connector part 50 on the ventilator side, it is added by the practitioner. The applied force is concentrated on “a part of the upper surface” of the first front taper 102A2, and the connector part 50 on the ventilator side can be pushed up with a smaller force. If the entire upper surface of the first front side detail 102A2 and the entire upper surface of the first rear holding portion 103A are in contact with the lower surface of the connector part 50 on the ventilator side, the practitioner Is applied to the entire lower surface of the connector portion 50, and in order to push up the connector portion 50, a larger force is required.
That is, according to the removal tool 100, it is in a state closer to a point contact with respect to the connector part 50 on the ventilator side. In other words, the latter has a larger contact area with the connector part 50 on the ventilator side than the former, and the force used to remove the connector part 50 on the ventilator side is dispersed. End up.

Thus, the removal tool 100 has the first front side detail 102A2, the second front side detail 102B2, the second front side clamping part 102B, and the second rear side clamping part 103B, which are tapered. Therefore, the removal tool 100 can concentrate the force on the connector unit 50.
The first front side detail 102A2, the second front side detail 102B2, the first rear side clamping part 103A and the second rear side clamping part 103B are tapered, that is, tapered. And the height position of the front-end | tip of 1st front side detail 102A2, 2nd front side detail 102B2, 1st rear side clamping part 103A, and 2nd rear side clamping part 103B is a center position of height width. is there. More specifically, the first front tapered portion 102A2 is tapered toward the center position of the height width of the upper surface and the lower surface (center position of the interval between the upper surface and the lower surface).

  When the facing distance between the first connector detaching portion 110A and the second connector detaching portion 110B is further narrowed, the connector portion 50 is pushed up by the contact portion P as shown in FIG. The exposed portion R of 6 becomes wider. Thereby, the connector part 50 by the side of the respirator moves to the upper side, and comes off by moving to a certain place. This amount of movement is indicated by Z in FIG. At this time, the relative position of the first connector removal portion 110A with respect to the second connector removal portion 110B is raised. As described above, the removal tool 100 can be detached as shown in FIGS. 8A to 8C by removing the connector part 50 on the ventilator side.

  When the first connector removing portion 110A rides on the second connector removing portion 110B, the tapered slope of the first front side detail 102A2 and the connector portion 50 on the ventilator side come into contact with each other. Similarly, the tapered slope of the second front tapered portion 102B2 and the ventilator-side connector portion 50 abut, and the tapered slope of the second front clamping portion 102B and the ventilator-side connector portion 50 are in contact with each other. And the tapered slope of the second rear holding portion 103B and the connector portion 50 on the ventilator side come into contact with each other. Thus, when the contact close | similar to a point (line) is implement | achieved, the power of the practitioner who uses the removal tool 100 will concentrate on the point (line). For this reason, while being able to remove both connectors quickly, a work burden can be suppressed.

  In addition, although the case where the taper part of the 1st front side detail 102A2 of the removal tool 100 which concerns on this Embodiment is a taper was demonstrated to the example, it is not limited to it. For example, the upper surfaces of the tapered portions of the first front side detail 102A2 and the first rear side clamping part 103A may be formed in a curved shape protruding toward the connector part 50 side. Similarly, the upper surfaces of the tapered portions of the second front side detail 102B2 and the second rear side clamping part 103B may be formed in a curved shape protruding toward the connector part 50 side. Thus, when it is formed in a curved surface shape, the area of the contact portion P described above can be reduced, and the force applied to the connector portion 50 can be concentrated.

Note that at least one of the upper and lower surfaces of the first front taper 102A2 and the first rear clamping part 103A and the upper and lower surfaces of the second front taper 102B2 and the second rear clamping part 103B. One surface is good to be formed in the curved surface shape which protrudes in the connector part 50 side.
Note that both the first front side detail 102A2 and the first rear side clamping portion 103A and the second front side detail 102B2 and the second rear side clamping portion 103B may be formed in a curved surface shape. , Either one may be formed. If both are formed, the second front taper 102B2 and the second front taper 102B2 and the second front taper 102B2 and the second rear taper 102A2 even when the first front taper 102A2 and the first rear clamping part 103A come upward when the removal tool 100 is closed Even if the rear holding portion 103B comes to the upper side, the curved surface and the connector portion 50 come into contact with each other, and convenience is improved.

  Further, the upper surfaces of the first front side detail 102A2 and the first rear side clamping part 103A are formed in a curved shape protruding toward the connector part 50 side, and the second front side detail 102B2 and the second rear side The lower surface of the sandwiching portion 103B may be formed in a curved shape protruding toward the connector portion 6 side. That is, when the removal tool 100 is closed and the first front side detail 102A2 and the first rear holding portion 103A are on the upper side, the first front side detail 102A2 and the second front side detail are considered. The contact surface with 102B2 and the contact surface between the first rear holding portion 103A and the second rear holding portion 103B are formed in a taper shape, but the first front taper 102A2 and the first That is, the upper surface of the rear clamping unit 103A, the second front side detail 102B2, and the lower surface of the second rear clamping unit 103B are formed in a curved shape. With this configuration, even if the removal tool 100 is turned upside down and the removal tool 100 is inserted into the connector part 6 and the connector part 50, the curved surface and the connector part 50 come into contact with each other, and convenience is improved.

Note that the removal tool 100 may be integrally formed of a resin, or may be integrally formed of a metal such as stainless steel. When the removal tool 100 is made of a resin, for example, a polyoxymethylene resin can be used. When the removal tool 100 is made of stainless steel or the like, the surface may be roughened by, for example, blasting to prevent slipping. For example, the surface of the first gripping part 101A and the second gripping part 101B may be blasted.
Further, the first front side clamping unit 102A, the first rear side clamping unit 103A, the second front side clamping unit 102B, and the second rear side clamping unit 103B may be blasted to roughen the surface. By performing blasting in this manner, the first front side clamping unit 102A, the first rear side clamping unit 103A, the second front side clamping unit 102B, and the second rear side clamping unit 103B are connected to the lower surface of the connector unit 50. It is hard to slip when it comes into contact with the connector part 50, and it becomes easier to remove the connector part 50.
Further, the first connector removal portion 110A and the second connector removal portion 110B are made of stainless steel, the first gripping portion 101A, the second gripping portion 101B, and the bent portion 111 are made of resin, and You may make it comprise the removal tool 100 by assembling.

  Further, the case where the first connector detaching portion 110A is rotated 180 degrees has been described by taking the case where the second connector detaching portion 110B has the same shape as an example. That is, although the case where the first connector removal portion 110A and the second connector removal portion 110B are line-symmetric has been described as an example, it is not limited thereto, and may be asymmetrical.

  Moreover, although the case where the 1st front side clamping part 102A and the 2nd front side clamping part 102B were provided in the forefront side of the removal tool 100 was demonstrated to the example, it is not limited to it. The first front-side clamping unit 102A and the second front-side clamping unit 102B may not be provided at the forefront as long as they are in front of the first rear-side clamping unit 103A and the second rear-side clamping unit 103B.

[Effects of removing tool 100 according to the present embodiment]
The removal tool 100 according to the present embodiment is not inserted between the connectors from one direction as in the removal tool 100 ′ (see FIG. 18) described in Patent Document 1 and Non-Patent Document 1, but from both directions. It has a structure to be sandwiched. That is, the removal tool 100 is capable of closing the first connector removal part 110A and the second connector removal part 110B and sandwiching both sides of the connector part 50 on the ventilator side and the connector part 6 with equal force. is there. For this reason, it is hard to make mistakes in the adjustment of force, and even if the adjustment of force is wrong, it is possible to prevent accident extubation.

  In the conventional removal tool 100 ′ of FIG. 18, when the rod-like member 101A ′ and the rod-like member 101B ′ are inserted between the connectors, the protruding portion Q shown in FIG. 18C may damage the patient tissue. However, since the removal tool 100 according to the present embodiment has a configuration in which both connectors are sandwiched from both directions, the distal ends of the first front side detail 102A2 and the second front side detail 102B2, and the first It is possible to suppress the occurrence of a situation in which the patient's tissue is injured by the contact between the front end of the first rear holding portion 103A and the second rear holding portion 103B and the piercing of the human body.

Since the removal tool 100 according to the present embodiment has a configuration in which both connectors are sandwiched from both directions, when the removal tool 100 is closed, the first connector removal portion 110A is detached from the second connector. It rides on the upper side of the part 110B. Therefore, the combined height of the first connector removal portion 110A and the second connector removal portion 110B can be ensured.
Depending on the combination of the connector unit 6 and the ventilator-side connector unit 50, the height of the portion R of the connector unit 6 exposed from the ventilator-side connector unit 50 may increase. However, in the detaching tool 100 according to the present embodiment, as described above, the heights of the first connector detaching portion 110A and the second connector detaching portion 110B can be ensured to be larger. It can suppress that it lacks.

  On the other hand, the connector part 6 is exposed from the ventilator-side connector part 50 of the connector part 6 because of the combination of the connector part 6 and the ventilator-side connector part 50 or the reason that the connector part 50 is pushed in strongly. In some cases, the height of the portion R is small. However, the removal tool 100 according to the present embodiment is easy to insert into the exposed portion R because the first connector removal portion 110A and the second connector removal portion 110B have a tapered shape. Can be reduced.

  When the removal tool 100 according to the present embodiment is closed, the contact area between the first connector removal part 110A and the second connector removal part 110B and the connector part 50 on the ventilator side when the removal tool 100 is closed. Is getting smaller. Thereby, it is suppressed that the force used for the removal of the connector part 50 on the ventilator side is dispersed, and the practitioner can quickly remove the connector part 50 on the ventilator side, and the practitioner. However, the work burden at the time of removing the connector part 50 on the side of the ventilator can be suppressed.

  As described above, according to the removal tool 100 according to the present embodiment, the connector portion 50 can be easily detached from the connector portion 6 while reducing the burden on the operator and the burden on the patient. , Can greatly improve the convenience.

[Modification 1]
FIG. 9 shows a first modification (referred to as a removal tool 200) of the removal tool 100 shown in FIG. FIG. 10 is an explanatory diagram showing how the connector part 50 on the ventilator side is removed by the removal tool 200 shown in FIG.
The removal tool 200 differs from the removal tool 100 in the shape of the first front side detail 202A2, the second front side detail 202B2, the first rear side clamping part 203A, and the second rear side clamping part 203B. is there. Moreover, the removal tool 200 differs from the removal tool 100 in the height position of the rib part 220, the height position of the first connector removal part 210A, and the height position of the second connector removal part 210B. The other first gripping part 201A, second gripping part 201B, bent part 211, first base part 202A1 and second base part 202B1 have the same shape as the removal tool 100.

  As shown in FIG. 9 (c), the first front side detail 202A2 has a shape formed such that the tip thereof is below the tip of the second front side detail 202B2. It is. That is, the first front side detail 202A2 has a surface that inclines downward as it goes from the right side to the left side of the paper surface of FIG. 9C. The second front taper 202B2 has a lower surface corresponding to the upper surface of the first front taper 202A2.

As shown in FIG. 10, when the removal tool 200 is closed, the second connector removal portion 210B rides on the first connector removal portion 210A. For this reason, similarly to the removal tool 100, the removal tool 200 can remove the ventilator-side connector part 50 from the connector part 6. However, when the second connector removal portion 210B rides on the first connector removal portion 210A, the removal tool 200 has a contact area between the second connector removal portion 210B and the connector portion 50 that is greater than that of the removal tool 100. It is wide (see the contact portion P1 in FIG. 10). For this reason, the removal tool 100 is easier to concentrate the force applied by the practitioner than the removal tool 200. In other respects, the removal tool 200 can obtain the same effects as the removal tool 100.
Note that the removal tool 200 is different from the removal tool 100 in terms of the vertical relationship between the first connector removal part 210A and the second connector removal part 210B when the removal tool 200 is closed. That is, when the upper and lower positions of the removal tool 200 shown in FIG. 10 are fixed and the both connectors (6, 50) are sandwiched, the second connector removal portion 210B comes above the first connector removal portion 210A. Conversely, when the vertical position of the removal tool 200 shown in FIG. 10 is reversed and both connectors (6, 50) are sandwiched, the first connector removal portion 210A comes above the second connector removal portion 210B. .

  The first front clamping unit 202A and the first rear clamping unit 203A correspond to the first clamping unit, and the second front clamping unit 202B and the second rear clamping unit 203B are the second clamping unit. It corresponds to.

[Modification 2]
FIG. 11 shows a second modification (referred to as a removal tool 300) of the removal tool 100 shown in FIG. FIG. 12 is an explanatory diagram showing how the connector part 50 on the ventilator side is removed by the removal tool 300 shown in FIG.
The removal tool 300 is different from the removal tool 100 in the shapes of the first connector removal part 310A and the second connector removal part 310B. The other first gripping portion 301A, second gripping portion 301B, bent portion 311 and rib portion 320 have substantially the same shape as the removal tool 100.

  The front side detail 302A2 and the rear side clamping portion 303A are formed so as to protrude toward the second gripping portion 301B, and taper, that is, taper toward the second gripping portion 301B. Here, the rear clamping portion 303 </ b> A corresponds to “rear side detail”. The front side detail 302A2 is formed such that the height of the tip thereof is at the height of the lower surface of the second connector removal portion 310B. Similarly, the rear holding portion 303A is formed such that the height position of the tip is located at the height position of the lower surface of the second connector removal portion 310B. As a result, when the facing distance between the front tapered portion 302A2 and the rear holding portion 303A and the second connector removing portion 310B is narrowed, the front tapered portion 302A2, the rear holding portion 303A and the second connector removing portion are arranged. It is possible to avoid the interference with 310B and the removal tool 300 from becoming difficult to close, and to push up and remove the connector portion 50 more reliably.

  As shown in FIGS. 11A to 11C, the removal tool 300 is longer than the first connector removal portion 110 </ b> A of the removal tool 100, and further has a large height. A removal portion 310A is provided. That is, the first connector removal portion 310A is formed with a front clamping portion 302A and a rear clamping portion 303A. The length and height of the base 302A1 and the front taper 302A2 of the front clamping unit 302A are the same as the first base 102A1 (second base 102B1) and the first front taper 102A2 (second) of the removal tool 100. Longer than the front taper 102B2). In addition, the length and height of the rear clamping unit 303A are longer than the first rear clamping unit 103A (second rear clamping unit 103B) of the removal tool 100. In other respects, the first connector removal portion 310A is the same as the first connector removal portion 110A. The reason why the length and the height width are increased in this way is not to insert the second connector removal portion 310B of the removal tool 300 into the exposed portion R of the connector portion 6. Because.

  More specifically, in the removal tool 300, it is necessary to remove the connector part 50 only by the height width of the first connector removal part 310A, so that the height of the corresponding part is higher than that of the removal tool 100. The width is increased. However, if only the height width is increased, the angle of the taper becomes tight and it becomes difficult to insert into the exposed portion R of the connector portion 6, and the force required to push up the connector portion 50 is also required accordingly. Therefore, the length of the removal tool 300 is also increased. Specifically, in a state in which the removal tool 300 is open, that is, in a state in which the first gripping portion 301A and the second gripping portion 301B are open, the removal tool 300 has a front end and a rear end of the front tapered portion 302A2. The tip of the side clamping portion 303A is formed so as to be located on the second gripping portion 301B side with the bent portion 311 as a boundary.

  The second connector detaching portion 310 </ b> B is used to support the connector portion 50. That is, the second connector removal portion 310B is not aligned with the exposed portion R of the connector portion 6, but is aligned with the connector portion 50. The second connector removal portion 310B is formed in a circular arc shape in accordance with the shape of the outer peripheral surface of the connector portion 50.

  As shown in FIG. 12, when the removal tool 300 is closed, the first connector removal portion 310 </ b> A pushes up the connector portion 50 and removes the ventilator-side connector portion 50 from the connector portion 6 in the same manner as the removal device 100. Can do. And the removal tool 300 is a thing with which the contact area of 310 A of 1st connector removal parts and the connector part 50 reduced like the removal tool 100 (refer contact part P2 of FIG. 12). For this reason, the removal tool 300 is easy to concentrate the force applied by the practitioner, like the removal tool 100.

  In FIG. 12, the tracheostomy tube 1 is described as an example in the same manner as in FIG. 7, but the description is omitted because the same applies to the tracheal tube 1B. In the description of FIG. 12, the front side clamping portion 302A of the first connector removing portion 310A is shown, and the description of the rear side clamping portion 303A is omitted for convenience of description.

  When removing the connector portion 6 from the connector portion 50, the practitioner attaches the first connector removal portion 310A and the second connector removal portion 310B to both connectors (6, 50) as shown in FIG. Match the connection position. More specifically, the practitioner makes the second connector removal portion 310B abut on the outer peripheral surface of the connector portion 50, and the connector on the ventilator side of the connector portion 6 is attached to the tip of the first connector removal portion 310A. The position of the first connector removal portion 310A is aligned so that the portion R exposed from the portion 50 is located. At this time, the exposed portion R is inserted between the front clamping portion 302A and the rear clamping portion 303A.

Then, the practitioner closes the first gripping portion 301A and the second gripping portion 301B, and narrows the facing distance between the first connector removal portion 310A and the second connector removal portion 310B. As a result, as shown in FIG. 12B, the upper surface of the front side detail 302A2 and the ventilator-side connector 50 are brought into contact (see the contact portion P2 in FIG. 12B). In the contact portion P2, the entire upper surface of the front tapered portion 302A2 is not in contact with the lower surface of the ventilator-side connector portion 50, but the ventilator-side connector is partially contacted with the upper surface of the front tapered portion 302A2. It is in contact with the lower surface of the portion 50. That is, the lower surface of the connector portion 50 is flat, but the upper surface of the front side detail 302A2 is not parallel to the flat lower surface and is inclined, so that artificial respiration is performed on a part of the upper surface of the front side detail 302A2. It contacts the lower surface of the connector part 50 on the container side.
In addition, although illustration is abbreviate | omitted, the back side clamping part 303A is also contact | abutting with the lower surface of the connector part 50 by the side of the ventilator so that it may correspond to the front side clamping part 302A.

  Since a part of the upper surface of the front taper 302A2 and a part of the upper surface of the rear clamping part 303A are in contact with the connector part 50 on the ventilator side, the force applied by the practitioner is the front taper 302A2. The connector part 50 on the side of the ventilator can be pushed upward with a smaller force. That is, the removal tool 300 has the front side detail 302A2 and the rear side clamping portion 303A, which are tapered, so that the removal tool 300 can concentrate the force on the connector portion 50.

  When the facing distance between the first connector removal portion 310A and the second connector removal portion 310B is further reduced, the connector portion 50 is pushed up by the contact portion P2 as shown in FIG. The exposed portion R of 6 becomes wider. Thereby, the connector part 50 by the side of the respirator moves to the upper side, and comes off by moving to a certain place. This amount of movement is indicated by Z in FIG. At this time, the relative position of the first connector removal portion 310A with respect to the second connector removal portion 310B is raised. As described above, the removal tool 300 operates as shown in FIGS. 12A to 12C so that the connector part 50 on the ventilator side can be detached.

The first connector removal portion 310A has a first clamping portion. And the front side clamping part 302A (front side detail 302A2) and the back side clamping part 303A (rear side detail) are the structures corresponding to a 1st clamping part.
The second connector removal portion 310B is formed with a second clamping portion. In the second modification, since the second connector removal portion 310B is not formed with a configuration such as the second front side sandwiching portion 102B of the removal tool 100, the second connector removal portion 310B and the second sandwiching portion Is the same configuration.

[Modification 3]
FIG. 13 shows a third modification (referred to as a removal tool 400) of the removal tool 100 shown in FIG. 13 (a) is a perspective view, FIG. 13 (b) is a view of the removal tool 400 seen from the upper surface side, and FIG. 13 (c) is the first connector removal portion 410A and the second connector removal portion 410A. It is the figure which looked at the removal tool 400 in the direction which goes to the bending part 411 side from the connector removal part 410B side. 14A is a side view of the removal tool 400 on the second connector removal portion 410B side, FIG. 14B is a side view of the first connector removal portion 410A side, and FIG. 14C is a removal tool. It is the figure which looked at 400 from the lower surface side.

  The removal tool 400 is different from the removal tool 300 according to the modified example 2 in that a bending portion 401A1 and a bending portion 401B1 are formed, and a first holding portion 430A and a second holding portion 430B are formed. Is different. Other configurations are common. In the third modification, the configuration different from the second modification will be mainly described.

  The removal tool 400 is bent between the first connector removal portion 410A and the first gripping portion 401A, and between the second connector removal portion 410B and the second gripping portion 401B. In the third modification, the first gripping portion 401A and the second gripping portion 401B are bent.

  More specifically, as shown in FIGS. 14 (a) and 14 (b), the first gripping portion 401A has a height position of the bent portion 411 higher than that of the first connector removing portion 410A. It is bent to be higher than the vertical position. A bent portion of the first gripping portion 401A is a bent portion 401A1. The bending portion 401A1 is formed on the end portion side of the first connector removal portion 410A in the first gripping portion 401A. Corresponding to this, the second gripping portion 401B has a bent portion 401B1, and the height position of the bent portion 411 is higher than the height position of the second connector removing portion 410B. It is bent and formed.

  As shown in FIG. 14A, the first gripping portion 401A and the second gripping portion 401B are bent clockwise θ with respect to the horizontal direction (in FIG. 14B, with respect to the horizontal direction). It is bent so as to form (counterclockwise). The bending angle θ may be set to about 15 degrees to 25 degrees, for example.

  As described above, since the bending tool 401A1 and the bending part 401B1 are formed in the removal tool 400, when the practitioner is grasping the removal tool 400, the bending part 411 is included in the palm of the practitioner. It comes in contact with the little finger side portion, and the removal tool 400 can be gripped more reliably.

  Note that the first connector removal portion 410A and the second connector removal portion 410B may be bent instead of the first gripping portion 401A and the second gripping portion 401B. That is, the bent portion 401A1 and the bent portion 401B1 may be formed in the first connector removing portion 410A and the second connector removing portion 410B.

  The removal tool 400 includes a first holding portion 430A provided at a connection position between the first gripping portion 401A and the first connector removal portion 410A, a second gripping portion 401B, and a second connector removal portion. And a second holding portion 430B provided at a connection position with 410B. Here, the removal tool 400 shows an example of a practitioner that is right-handed.

  When the practitioner is right-handed, the first holding portion 430A is a portion that is held by, for example, the thumb of the practitioner, and the second holding portion 430B is a portion that is held by, for example, the index finger of the practitioner . Here, the first holding portion 430A is formed with a plurality of rows of protruding portions 430A1 so that the operator's finger can be easily caught. A plurality of rows of protrusions 430B1 corresponding to the plurality of rows of protrusions 430A1 are also formed in the second holding portion 430B. The shapes of the protrusions 430A1 and the protrusions 430B1 will be described later with reference to FIG.

  The third modification differs from the second modification in the formation position of the rib portion 420. The rib portion 420 is continuously formed on the upper end side of the inner side surface of the first gripping portion 401A, the upper end side of the inner side surface of the bent portion 411, and the upper end side of the inner side surface of the second gripping portion 401B. . When the practitioner closes the removal tool 400 and removes the connector unit 50, the practitioner does not always apply a uniform force to the finger contact surface of the first holding unit 430A and the finger contact surface of the second holding unit 430B. Absent. That is, the practitioner may close the removal tool 400 by applying force to the upper side of the first holding part 430A and the upper side of the second holding part 430B. This is because when the force is applied in this manner, the connector portion 50 is easily held by the second connector removal portion 410B while the first connector removal portion 410A is pushed between the connector portion 50 and the connector portion 6. In this way, considering that the force may be applied more strongly on the upper side of the first holding part 430A and the upper side of the second holding part 430B, the rib part 420 has the first The upper end side of the inner side surface of the gripping portion 401A, the upper end side of the inner side surface of the bent portion 411, and the upper end side of the inner side surface of the second gripping portion 401B are provided to reinforce the removal tool 400. Thus, although the rib part 420 is formed in a different position from the rib part 320 of the second modification, it may be formed at the same position as the rib part 320.

  FIG. 15 is an explanatory diagram of a plurality of rows of protrusions 430B1 formed in the second holding part 430B. The second holding unit 430B has a configuration in which a practitioner's finger can be easily caught and the finger can be prevented from slipping. The protrusion 430B1 is formed with a plurality of rows of protrusions. That is, the protrusions 430B1 are formed such that a plurality of protrusions formed so as to extend in the vertical direction are arranged in the horizontal direction with a predetermined interval therebetween.

  Further, although not shown in FIG. 15, the first holding portion 430A is also formed with a plurality of rows of convex portions (see FIG. 14B). That is, the plurality of rows of protrusions 430A1 of the first holding portion 430A are also formed such that a plurality of protrusions formed so as to extend in the vertical direction are arranged in the horizontal direction at predetermined intervals. It is.

As described above, the first holding portion 430A and the second holding portion 430B are formed with the non-slip convex portions formed so as to extend in the vertical direction, so that the practitioner uses the removal tool 400. The finger can be prevented from slipping in the longitudinal direction of the detaching tool 400 during the operation.
Further, the removal tool 400 is provided with a first holding part 430A between the first gripping part 401A and the first connector removal part 410A, and the second gripping part 401B and the second connector removal are provided. A second holding portion 430B is provided between the portion 410B. That is, the first holding part 430A and the second holding part 430B are located at positions where the fingertips come into contact when the practitioner holds the removal tool 400, and the practitioner applies a force to open and close the removal tool 400. It has become easier.

  In addition, in FIG. 15 of this modification 3, etc., the case where the protrusions 430B1 are a plurality of rows of protrusions is shown as an example. However, the present invention is not limited thereto, and for example, the surface is roughened to protrude. The first holding portion 430A and the second holding portion 430B may be provided with a function of preventing slipping.

  FIG. 16 is a view of the first holding portion 430A, the second holding portion 430B, the first connector removing portion 410A, and the second connector removing portion 410B as viewed from the lower surface side. FIG. 16 shows a state in which the first holding unit 430A and the second holding unit 430B are closed.

  The second holding portion 430B is formed so as to protrude below the lower surface of the second connector removal portion 410B. That is, the second holding portion 430B is formed to project in a direction perpendicular to the paper surface of FIG. How much the second holding portion 430B protrudes from the lower surface of the second connector removal portion 410B is indicated by the protrusion amount D in FIG. 14A described above.

  Here, when the removal tool 400 is opened and closed, the rear clamping unit 403A draws an arc-shaped track. Since the second holding portion 430B is formed so as to protrude below the lower surface of the second connector removal portion 410B, the second holding portion 430B is formed on the locus formed when the rear holding portion 403A moves. If the holding portion 430B is disposed, the rear holding portion 403A and the second holding portion 430B interfere with each other, and the removal tool 400 may not be opened or closed, or may not be opened or closed. Therefore, the second holding portion 430B is formed such that the end portion 430B2 on the second connector detaching portion 410B side does not protrude forward relative to the locus drawn by the rear holding portion 403A. Further, the end portion 430B2 is formed from the second connector detaching portion 410B side to the second gripping portion 401B side so that the opening / closing of the detaching tool 400 becomes smooth when abutting against the rear holding portion 403A. Has a smooth curved surface.

  FIG. 17 is an explanatory diagram of how the connector part 50 on the ventilator side is removed by the removal tool 400 shown in FIG. The operation of the removal tool 400 is substantially the same as the operation of the removal tool 300 described in FIG. As shown in FIG. 17, when the removal tool 400 is closed, the first connector removal portion 410 </ b> A pushes up the connector portion 50 and removes the ventilator-side connector portion 50 from the connector portion 6 in the same manner as the removal device 100. Can do. And the removal tool 400 becomes the thing with which the contact area of 410 A of 1st connector removal parts and the connector part 50 reduced similarly to the removal tool 100 (refer contact part P2 of FIG. 17). For this reason, the removal tool 400 is easy to concentrate the force applied by the practitioner, like the removal tool 100.

(1) When the removal tool 400 is used upside down, the second connector removal portion 410B does not hold the connector portion 50 but holds the connector portion 6. For this reason, when the first connector removal part 410A is inserted between the connector part 6 and the connector part 50, the insertion part of the first connector removal part 410A moves upward in the connector part 50. In some cases, the side opposite to the insertion side does not move upward and the connector portion 50 is inclined. Then, the connector part 6 and the connector part 50 are strongly adhered, and the first connector removal part 410A cannot be pushed between the connector part 6 and the connector part 50, and the connector part 50 cannot be removed. It may be difficult to remove.
(2) Moreover, if the removal tool 400 is used upside down, it interferes with the flange 6a of the connector portion 6.
Thus, the removal tool 400 does not function when used upside down.

  The removal tool 400 of the third modification has a bent portion 401A1 and a bent portion 401B1. That is, the practitioner can easily determine the up and down of the removal tool 400 by visually determining whether the bent portion 411 side is higher than the first connector removal portion 410A and the second connector removal portion 410B side. It is like that. For this reason, it can avoid using the removal tool 400 upside down as mentioned above.

  Moreover, since the bending tool 401A1 and the bending part 401B1 are formed in the removal tool 400 of Modification 3, when the practitioner is holding the removal tool 400, the bending part 411 is included in the palm of the practitioner. Touching the little finger side makes it easier for the practitioner to grip. Conversely, when the practitioner holds the removal tool 400 upside down, the bent portion 411 is separated from the practitioner's palm, so it is difficult to grasp. For this reason, it is also possible to judge up and down by the touch with the removal tool 400, without judging up and down visually.

Note that a first clamping portion is formed in the first connector removal portion 410A. And the front side clamping part 402A (front side detail 402A2) and the back side clamping part 403A (rear side detail) are the structures corresponding to a 1st clamping part.
The second connector removal portion 410B is formed with a second clamping portion. In the second modification, since the second connector removal portion 410B is not formed with a configuration such as the second front side sandwiching portion 102B of the removal tool 100, the second connector removal portion 410B and the second sandwiching portion Is the same configuration.
