Detailed Description
The embodiment of the utility model provides a flow controller, which is applied to a medical negative pressure aspirator and solves the technical problems of low efficiency and low accuracy when the suction flow of the negative pressure aspirator is regulated in the related technology.
In order to solve the technical problems, the embodiment of the utility model provides the following general ideas:
the flow controller is matched with a negative pressure pipe of the medical negative pressure aspirator, then the fine adjustment handle can extrude the negative pressure pipe by changing the included angle between the fine adjustment handle and the fine adjustment pipe body, the smaller the included angle is, the larger the extrusion pressure is, the smaller the cross-sectional area of the negative pressure pipe is, so that the control of the suction flow of the negative pressure pipe is realized, and the efficiency and the accuracy of regulation control are improved when the suction flow of the negative pressure aspirator is regulated.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
In a first aspect, an embodiment of the present invention provides a flow controller, which is applied to a medical negative pressure aspirator, where the medical negative pressure aspirator includes a negative pressure bottle and a negative pressure tube connected to the negative pressure bottle. When the medical negative pressure aspirator works, air negative pressure can be generated in the negative pressure bottle, so that the negative pressure pipe also has the same air negative pressure, and dirt, such as dirty blood, phlegm and the like can be sucked into the negative pressure bottle from the negative pressure pipe by utilizing the air negative pressure.
Referring to fig. 1, in an embodiment of the present invention, a flow controller includes: a fine adjustment tube body 100 and a fine adjustment handle 200. Wherein, fine adjustment handle 200 is through pivot 300 and fine adjustment body 100 swivelling joint, and pivot 300 is perpendicular to the axial of fine adjustment body 100, and fine adjustment body 100 is provided with the first through-hole 400 that is used for wearing to establish negative pressure pipe 600 to and the uncovered 500 that supplies fine adjustment handle 200 to pass.
In a specific implementation process, the first through hole 400 may be disposed in an axial direction of the fine adjustment tube body 100, so that the negative pressure tube 600 can pass through the fine adjustment tube body 100, and specifically, a diameter of the first through hole 400 is greater than a diameter of the negative pressure tube 600.
For example, the diameter of the first through hole 400 may be 14mm to 20mm, for example, 14mm, 16mm, or 20 mm.
In a specific implementation, a small hole (not shown) may be respectively disposed at two ends of the rotating shaft 300, and the two small holes should be perpendicular to the axial direction of the rotating shaft 300. After the fine adjustment handle 200 is rotatably connected with the fine adjustment tube 100 through the rotating shaft 300, the bolt can be inserted into the small hole at the two ends of the rotating shaft 300, so that when the fine adjustment handle 200 and the fine adjustment tube 100 rotate relatively, the rotating shaft 300 cannot fall off, and the unstable rotation connection between the fine adjustment handle 200 and the fine adjustment tube 100 is avoided.
In a specific implementation, in order to enable the fine adjustment handle 200 to press the negative pressure pipe 600, an opening 500 may be provided on the fine adjustment handle 200. Specifically, the opening 500 is communicated with the first through hole 400, and when the fine adjustment handle 200 is rotated, the fine adjustment handle 200 can pass through the opening 500 to press the negative pressure pipe 600, thereby reducing the cross-sectional area of the negative pressure pipe 600 at that position, and reducing the suction flow rate through the negative pressure pipe 600.
In order to prevent the flow controller from moving freely on the negative pressure tube 600 and reduce the influence of the flow controller on clinical work during the use of the flow controller, referring to fig. 2, a first locking thread 101 and a first locking nut 102 may be provided on the fine adjustment tube body 100.
In a specific implementation process, the first locking screw 101 may be respectively disposed at two ends of the fine adjustment pipe body 100, and of course, the first locking screw 101 may be disposed at only one end thereof. Specifically, at the position where the first locking thread 101 is provided, notches as shown in fig. 1 may be provided, the inner diameter of the first locking nut 102 is smaller than the outer diameter of the fine adjustment pipe body 100, and the inner diameter of the first locking nut 102 is larger than the diameter of the negative pressure pipe 600. Referring to fig. 3a and 3b, the following description is provided for the locking principle:
first, because the breach can reduce the intensity of the accurate adjustment body 100 in relevant position, when receiving the exogenic action, the accurate adjustment body 100 of breach position can take place deformation to make this external diameter of the accurate adjustment body 100 of department change.
Secondly, since the inner diameter of the first locking nut 102 is smaller than the outer diameter of the fine adjustment tube 100, the outer diameter of the fine adjustment tube 100 at the position of the gap is reduced by the binding force of the first locking nut 102, as shown in fig. 3a, when the displacement of the first locking nut 102 is x1When the minimum value of the outer diameter of the fine adjustment pipe body 100 is
When the displacement of the first lock nut 102 is x, as shown in fig. 3b2When the minimum value of the outer diameter of the fine adjustment pipe body 100 is
As will be apparent from the above description,if x1＜x2Then, then
That is to say: the smaller the rotational displacement of the first lock nut 102 on the first lock thread 101, the smaller the minimum value of the outer diameter of the fine adjustment pipe body 100. When the minimum value of the outer diameter of the fine adjustment tube body 100 is smaller than the diameter of the negative pressure tube 600, the fine adjustment tube body 100 can lock the negative pressure tube 600, so that the flow controller does not generate relative displacement with the negative pressure tube 600.
In addition, a non-slip pad may be further disposed on an inner wall of the first through hole 400 at the position of the first locking thread 101 to enhance the locking performance of the first locking nut 102, thereby enhancing the fixing effect.
To facilitate gripping of the flow controller and to better apply a squeezing force to the negative pressure tube 600. Referring to fig. 2, the fine adjustment handle 200 may include a handle 201 and a pressing rod 202, one end of the handle 201 is connected to the pressing rod 202, and an included angle between the handle 201 and the pressing rod 202 is an acute angle. Wherein, the handle 201 is used for the user to hold to in order that the user exerts the extrusion force, thereby through the rigid connection between handle 201 and the press bar 202, the extrusion force that the user exerted can transmit to press bar 202, and then realizes exerting the extrusion force to the negative pressure tube 600 through pressing handle 201.
It should be noted that, in order to ensure the safety of the user during the operation of the flow controller, the handle 201 and the pressing rod 202 should not be sharp and sharp, and the handle 201 and the pressing rod 202 should have a certain yield strength to prevent the handle 201 and the pressing rod 202 from breaking and losing the corresponding functions during the operation.
In addition, in order to ensure the comfort of the user using the flow controller, the handle 201 and the fine adjustment tube 100 may be configured to have an ergonomic shape, for example, the handle 201 may be configured to have a stick shape with two thinner ends and a thicker middle, and the fine adjustment tube 100 may be configured to have a tube shape with two thicker ends and a thinner middle.
As an alternative embodiment, in order to prevent the fine adjustment handle 200 from swinging too much, causing unexpected swing collision, and also to facilitate rapid pressing of the negative pressure tube 600. Referring to fig. 2, a stopper 103 for limiting the rotation of the fine adjustment handle 200 may be provided on the fine adjustment tube 100.
In a specific implementation process, the limit block 103 can be arranged between the handle 201 and the pressing rod 202, so that the pressing rod 202 can only rotate between the negative pressure tube 600 and the limit block 103, and the limitation on the swing angle of the fine adjustment handle 200 is realized.
As an alternative embodiment, in order to facilitate the understanding of the change of the suction flow rate of the negative pressure tube 600 after the flow rate controller is used, a dial 203 may be provided on the fine adjustment handle 200. Correspondingly, a pointer 104 corresponding to the dial 203 may be provided on the fine adjustment pipe body 100.
In the implementation, when the pressing rod 202 just contacts the negative pressure tube 600, the suction flow of the negative pressure tube 600 is constant, and the position of the dial 203 aligned with the pointer 104 at this time can be marked as the starting value. The initial value may be a number 0, and may of course be Lv0, which is not illustrated herein for the sake of simplicity of the description.
Since the dial 203 is rotated by a corresponding angle when the pressing rod 202 is pressed against the negative pressure tube 600, the pointer 104 is aligned with a new position on the dial 203. This new position can characterize the compression stroke of the compression rod 202 on the negative pressure tube 600, the larger the compression stroke, the smaller the cross-sectional area of the negative pressure tube 600 there, and the smaller the suction flow through the negative pressure tube 600. Specifically, the compression stroke can be obtained by the following formula:
L＝Lrod×(sinθ′-sinθ)；
Wherein L is the pressing stroke of the pressing rod 202 to the negative pressure tube 600, LRodThe distance from the end of the pressing rod 203 to the rotating shaft 300, θ' is the angle between the current pressing rod 203 and the horizontal line, and θ is the angle between the pressing rod 203 and the horizontal line when the pressing rod 203 just contacts the negative pressure tube 600.
In the concrete implementation process, the relationship between the compression stroke and the cross-sectional area of the negative pressure pipe 600 can be obtained through experiments, so that the control value of the suction flow rate can be represented on the dial 203, and further, the pointer 104 is aligned with the control value on the dial 203 through rotating the fine adjustment handle 200, so that the suction flow rate of the negative pressure pipe 600 can be accurately controlled.
As an optional embodiment, in order to achieve finer control when controlling the suction flow rate of the negative pressure tube 600, referring to fig. 4 to 5, the flow rate controller may further include: the assembly 700 is coarsely adjusted.
Specifically, the one end and the fine adjustment body 100 swivelling joint of coarse adjustment subassembly 700, coarse adjustment subassembly 700 include coarse adjustment body 701 and coarse adjustment knob 702, and wherein, coarse adjustment body 701 is provided with the second through-hole 7011 that is used for wearing to establish negative pressure pipe 600, and coarse adjustment body 701 is provided with the third through-hole 7012 that is used for wearing to establish coarse adjustment knob 702, second through-hole 7011 and third through-hole 7012 intercommunication.
In a specific implementation process, a connection rotating shaft (not shown) may be disposed at one end of the coarse adjustment tube 701, and the connection rotating shaft is rotatably connected to the fine adjustment tube 100, and specific implementation details of the connection rotating shaft may refer to the implementation details of the rotating shaft 300, which are not described herein again for brevity of the description.
In a specific implementation process, details of implementing the second through hole 7011 may refer to details of implementing the first through hole 400, which are not described herein again.
In a specific implementation process, a blocking piece 7015 is arranged on the inner wall of the third through hole 7012, the coarse adjustment knob 702 is provided with a boss 7021 which is complementary to the blocking piece 7015 in shape, and the distance between the boss 7021 and the pressing sphere 7022 is a coarse adjustment stroke.
Specifically, in the process that the coarse adjustment knob 702 passes through the blocking piece 7015, pressing the sphere 7022 can squeeze the negative pressure tube 600, and the greater the distance between the pressing sphere 7022 and the blocking piece 7015, the greater the squeezing force on the negative pressure tube 600. When the boss 7021 is located between the negative pressure tube 600 and the blocking piece 7015, at this time, the coarse adjustment knob 702 is rotated by a certain angle, and the boss 7021 is limited by the blocking piece 7015, so that the coarse adjustment knob 702 cannot be extruded from the third through hole 7012 under the elastic force action of the negative pressure tube 600. At this time, the pressing force of the rough adjustment knob 702 on the negative pressure pipe 600 is maximized.
It should be noted that the coarse adjustment stroke of the coarse adjustment knob 702 can be set according to the use requirement, and the larger the coarse adjustment stroke is, the larger the pressing force of the coarse adjustment knob 702 on the negative pressure tube 600 is. For example, the coarse adjustment stroke may be set to be half of the diameter of the negative pressure tube 600, or may be set to be one third of the diameter of the negative pressure tube 600.
The rough adjustment assembly 700 can be arranged at the upstream of the fine adjustment pipe body 100, of course, the rough adjustment assembly 700 can also be arranged at the downstream of the fine adjustment pipe body 100, the fine adjustment handle 200 and the rough adjustment knob 702 are utilized to extrude the negative pressure pipe 600, and when the negative pressure pipe 600 is controlled to absorb the flow, a finer control effect can be achieved.
In order to avoid the random movement of the coarse adjustment assembly 700 on the negative pressure tube 600 and reduce the influence of the coarse adjustment assembly 700 on clinical work, a second locking thread 7013 and a second locking nut 7014 may be provided on the coarse adjustment tube body 701.
