Description

  The present invention relates to an infusion needle removal preventer that prevents an indwelling needle for infusion from being pulled out due to an accident or being pulled out by a patient.

  FIG. 8 shows a conventional infusion performed when supplying nutrients or transfusing. As shown in the figure, in the case where the infusion needle 51 is stabbed into the patient's arm A continuously, in order to prevent the infusion needle 51 from being removed, a transparent tape 52 is applied on the infusion needle 51 and the infusion is further performed. In general, the tube 53 is fixed with a fixing tape 54.

  By the way, there are various patients who receive infusion. For this reason, there are cases where it is not sufficient to fix the transparent tape 52 or the fixing tape 54 alone. Patients include, for example, those with severe and mild disturbances of consciousness, dementia and dementia that are common in the elderly. Alternatively, some patients have poor understanding of infusion devices and methods of use. Of these, patients with mild insufficiency can understand the contents of the explanation. For example, if the precautions when moving while instilling are described, fixing with the above-mentioned transparent tape 52 or fixing tape 54 Is often sufficient.

  However, patients with consciousness disorder, dementia, dementia, severe insufficiency, etc. often have insufficient fixation with the transparent tape 52 or the fixing tape 54 described above. For this reason, these patients are dealt with by so-called suppression, which restrains a part of the body and deprives freedom according to the patient's symptoms. This restraint requires a physical restraint consent form, but it is completely pre-prepared from all patients and their families in preparation for a dripping needle removal accident that is difficult to predict. It is difficult. Also, for patients, suffering physical and mental distress due to suppression. On the other hand, from the viewpoint of doctors and nurses, there is always a risk of removal, and in the unlikely event that a removal accident occurs, the submission of an accident report is a cause of considerable stress. . For this reason, both the patient side and the doctor / nurse side do not need to be restrained, can be easily worn on the arm, and can be reliably prevented from being removed after wearing. There is a strong need for preventive devices.

  Therefore, in order to make it more difficult for the drip needle to come off, Patent Document 1 proposes a method in which a synthetic resin sheet is wound around a portion where the drip needle of the arm is pierced and is covered with a cylindrical shape by stopping with an adhesive tape or a hook-and-loop fastener. ing. Further, Patent Document 2 proposes that an arm with a drip needle is placed on a substantially flat underlay mat having elasticity or flexibility, and the arm is covered with a transparent or translucent protective cover having a substantially arc-shaped cross section. Has been.

<Embodiment 1>

  1, 2 and 3 show a drip needle removal preventing device 10 according to the present invention. 1 is a development view of the drip needle removal preventing device 10, FIG. 2 is a view for explaining the inside of the connecting member 11 in FIG. 1, and FIG. 3 is a view when the drip needle removal preventing device 10 is attached to the arm. It is an enlarged view of the vicinity of the winding convex part 16. In the following description, in the drip needle removal preventing device 10, the left-right direction in FIGS. 1 and 2 is referred to as “length direction (winding direction)”, and the up-down direction is referred to as “width direction”. The length direction corresponds to the periphery of the arm, and the width direction corresponds to the longitudinal direction of the arm.

  As shown in these drawings, the drip needle removal preventing device 10 includes a connecting member 11, A surfaces (female portions) 12 and 13 of a hook and loop fastener, B surfaces (male portions) 14 and 15 of the hook and loop fastener, Hanging projections 16 and 17 are provided.

  The connecting member 11 includes a cloth-like member 20 formed in a bag shape, and rubber (elastic members) 21 and 22 (see FIG. 2) disposed on the inside thereof. The cloth-like member 20 is formed in a double shape (bag shape), and the base end portions 12a and 13a of the A surfaces 12 and 13 are attached to the left end portion 20a in FIGS. Further, base end portions 14 a and 15 a of the B surfaces 14 and 15 are attached to the right end portion 20 b of the cloth-like member 20. The rubber 21 has one end portion 21a attached to the upper end side (elbow side in FIGS. 4 and 5) of the base end portion 12a of the A surface 12 in FIGS. 1 and 2, and the other end portion 21b in the B surface. 14 is attached to the upper end side of the base end portion 14a. The rubber 22 has one end portion 22 a attached to the lower end side (the wrist side in FIGS. 1 and 2) of the base end portion 13 a of the A surface 13 and the other end portion 22 b being the base end portion of the B surface 15. It is attached to the lower end side of 15a. The lengths of these rubbers 21 and 22 are set to be shorter than the length in the winding direction of the cloth-like member 20 in a natural state, that is, in a state where the drip needle removal preventing device 10 is not attached to the arm. In other words, in the natural state where the rubbers 21 and 22 are contracted, the cloth-like member 20 is in a loose state. Therefore, the cloth-like member 20 and the rubbers 21 and 22 are stretched at the time of wearing, but the extension limit of the rubbers 21 and 22 is restricted to the length when the cloth-like member 20 is stretched. Thereby, it can be tightened with an appropriate force without excessively tightening the arms with the rubbers 21 and 22 at the time of wearing.

  The A surfaces 12 and 13 are formed in a rectangular shape that is long in the winding direction, and the base end portions 12a and 13a are attached to the cloth-like member 20 as described above so as to be adjacent to each other in the width direction. Yes. Cloth-like members 23 and 24 that are slightly larger than these are attached to the back surfaces of the A surfaces 12 and 13. Since the cloth-like members 23 and 24 and the cloth-like member 20 of the above-described connecting member 11 are in direct contact with the patient's arm, a material with less irritation, for example, flannel or cotton is selected. . An appropriate gap G is provided between the cloth-like members 23 and 24. After the drip needle removal preventing device 10 is attached to the arm and fixed with a tape (not shown), the drip tube 25 (see FIG. 4) is taken out from the gap G. The A surfaces 12 and 13 have locking surfaces A1 and A1 on the surface side, respectively, and winding projections 16 and 17 to be described later project from substantially the center of the locking surfaces A1 and A1.

  Similarly to the A surfaces 12 and 13, the B surfaces 14 and 15 are also formed in a rectangular shape that is long in the winding direction, and are adjacent to each other in the width direction, as described above. 15 a is attached to the cloth-like member 20. The back surfaces of the B surfaces 14 and 15 are locking surfaces B1 and B1. The width W1 of the B surfaces 14 and 15 is set to be narrower than the width W2 of the A surfaces 12 and 13 described above. This is when the locking surfaces B1 and B1 of the B surfaces 14 and 15 are engaged with (attached to) the locking surfaces A1 and A1 of the A surfaces 12 and 13 when the drip needle removal preventing device 10 is mounted. This is for preventing a part of the B surfaces 14 and 15 from protruding from the cloth-like member 23 on the A surfaces 12 and 13 side and touching the patient's arm. As described above, since the A surfaces 12 and 13 and the B surfaces 14 and 15 are divided into two in the width direction, when the drip needle removal preventing device 10 is attached to the arm, the entire surface is easily fitted to the arm.

  As shown in FIGS. 1, 2, and 3, the winding protrusions 16 and 17 are provided so as to protrude substantially at the center of the locking surfaces A <b> 1 and A <b> 1 of the A surfaces 12 and 13. Since these winding convex parts 16 and 17 are the same shape, the winding convex part 16 is demonstrated to an example. As shown in FIG. 3, the winding projection 16 has a mounting portion 16a at the base end portion, a winding portion 16b at the intermediate portion, and a retaining portion 16c at the distal end portion. The attachment portion 16a is formed in a substantially elliptical shape, and is fixed to the locking surface A1 of the A surface 12. The winding part 16b is smaller than the attachment part 16a and is formed in a thick disk shape. The thickness of the winding portion 16b is set to be approximately the same as the outer diameter of the drip tube 25. At least the outer peripheral surface of the winding portion 16b is covered with a member having a large coefficient of friction with the drip tube 25. This is because when the drip tube 25 is wound around the winding portion 16b and set, and the drip tube 25 is pulled unnecessarily, it is difficult to come off the winding portion 16b. The diameter of the winding part 16b is set so as not to become too small. If this is too small, when the drip tube 25 is wound around the winding portion 16b, the drip tube 25 is bent with a small radius, and there is a possibility that the flow of liquid in the drip tube 25 may be inhibited. is there. The retaining portion 16c is formed in a disk shape (flange shape) that is slightly larger than the above-described winding portion 6b. The retaining portion 16a is for preventing the drip tube 25 from coming off from the winding portion when the drip tube 25 is wound around the winding portion 16b and after the drip tube 25 is wound.

  4 and 5 show usage examples of the drip needle removal preventing device 10 having the above-described configuration. An infusion needle (not shown) is pierced into the arm and then fixed to the arm with a tape (not shown). A site where the drip needle is fixed is referred to as a fixed site P. However, in FIG. 4 and FIG. 5, a portion immediately outside the drip needle in the drip tube 25, that is, a portion taken out first from between the arm and the drip needle removal preventing device 10 in the drip tube 25 connected to the drip needle. Is illustrated.

  The drip needle removal preventing device 10 is adapted so that the gap between the A surfaces 12 and 13 of the hook and loop fastener (substantially the same as the gap G of the cloth-like members 23 and 24 in FIG. 1) corresponds to the fixing portion P of the drip needle. The A faces 12 and 13 are put on the arm. Then, as described later, the drip tube 25 is appropriately wound around the winding convex portions 16 and 17, and then the B surface 14 and 15 are wound around the arm while the connecting member 11 is stretched in the winding direction. , 13. Thus, the drip tube 25 is wound around the winding convex portions 16 and 17, and the portions other than the wound portions are also bonded to each other by the A surface 12 and 13 and the B surfaces 14 and 15. Firmly sandwiched. For this reason, for example, even when the drip tube 25 is strongly pulled by the patient, the force does not reach the drip needle, so that the removal of the drip needle can be effectively prevented. Furthermore, since the drip needle removal preventing device 10 uses a hook-and-loop fastener, it can be easily attached to and removed from the patient.

  Furthermore, with reference to FIG. 4, FIG. 5, the specific example of an infusion line is demonstrated. Among these, FIG. 4 shows the case where the fixed part P of the drip needle is a general part of the patient's arm M, and FIG. 5 shows the case where the part is close to the wrist.

  The infusion line A shown in FIG. 4 starts from the fixing portion P of the infusion needle, extends the infusion tube 25 to the elbow side (right side in the figure), winds it around the winding convex portion 16 by a half circumference, and then the wrist side ( Folded back to the left side in the figure, hung a little on the winding convex part 17, and then put out on the wrist side.

  In the drip line B, the drip tube 25 is further wound around the drip line A from the above-described drip line A and wound around the convex portion 17 by a half circumference, folded back to the elbow side, and taken out above the B surface 14.

In the drip line C, the drip tube 25 is further sandwiched between the A surface 12 and the B surface 14 from the above-mentioned drip line B, and is put out on the elbow side along the winding convex portion 16.
The infusion line D shown in FIG. 5 starts from a location where the drip needle fixing portion P is close to the wrist and extends from the winding convex portion 17 to the elbow side along the winding convex portion 16. In addition, when there is room in the length of the drip tube 25, it is good to wind around the winding convex part 16 for one round.

  In the drip line E, the drip tube 25 is further wound around the drip line D from the drip line D described above, wound around the convex portion 16 by a half circumference, folded back to the wrist side, and put out above the B surface 13.

  4 and 5 are examples of an infusion line, and the infusion needle removal preventing device 10 according to the present invention has a large or small possibility that the infusion needle is removed by a patient, for example. Depending on the, any infusion line can be constructed. In this case, for example, the number of the winding protrusions may be further increased.

  6 and 7, a drip needle removal prevention device 10 according to the present invention is attached to a patient's arm M to construct an infusion line, and then a sleeve-like cover 30 covering the whole is shown. 6 shows a state in which the drip needle removal preventing device 10 is covered with the cover 30, and FIG. 7 shows a cross section. However, in order to simplify the description in FIG. 7, the drip needle extraction preventing device 10 is illustrated in a simplified ring shape. The cover 30 is formed in a cloth shape, and the width thereof is a little wider than the drip needle removal preventing device 10, and the length in the winding direction is slightly longer than one arm. The cover 30 has a base end portion 30a integrally attached to the drip needle removal preventing device 10, and a female portion 31 of a hook-and-loop fastener is provided in the vicinity of the base end portion 30a over the entire width. On the other hand, a male portion 32 of a hook-and-loop fastener is provided at the front end portion 30b of the cover 30 over the entire width. The cover 30 can be mounted by attaching the drip needle removal preventing device 10 to the arm M, then winding the cover 30 from above, and bonding the male portion 32 of the distal end portion 30b to the female portion 31 of the proximal end portion 30a. it can. Thereby, since the drip line can be covered from the patient, the possibility of removing the drip needle can be further reduced. In addition, as shown in FIG. 6, when rubber | gum is attached to the both ends of the width direction of the cover 30 over the full length of a winding direction, the fitting feeling after mounting | wearing can be improved. It can also be configured integrally with the needle removal prevention tool 10.

  In the above embodiment, the case where the A surfaces 12 and 13 of the hook and loop fastener are divided into two parts and the B surfaces 14 and 15 are divided into two parts corresponding thereto is described as an example. Thus, the fit for the patient may be further enhanced. On the contrary, when there is no necessity, you may make it not divide | segment A surface and B surface.

  In the above-described embodiment, the case where the A surfaces 12 and 13 of the hook and loop fastener are female portions and the B surfaces 14 and 15 are male portions has been described as an example. In the male part, the B surfaces 14 and 15 can be female parts. In this case, the same effect can be obtained.

  In addition, the connecting member 11 to which the A surfaces 12 and 13 and the B surfaces 14 and 15 are attached is configured by the cloth-like member 20 and the rubbers 21 and 22. Instead, a stretchable cloth-like member is used. You may do it.

  Further, the shape of the winding portion 16b of the winding convex portion 16 has been described above in the case where it is formed in a circular shape. However, instead of this, an elliptical shape or a track shape (for an athletic stadium) should be used. You can also. In any case, it is preferable that the wound drip tube is shaped and sized so as not to bend with a small radius.
