Description

An anti-stick type retention needle

technical field

The utility model relates to the technical field of retention needles, in particular to an anti-stick retention needle.

Background technique

The retained needle refers to a needle that penetrates into the blood vessel once and can be used repeatedly during long-term injection, which can reduce the pain of multiple injections for patients, especially for patients with edema. The utility model patent with the application number CN202122452146.8 includes the indwelling needle and the needle handles fixedly installed on both sides of the indwelling needle respectively. The backs of the two needle handles are fixed with medical pressure-sensitive adhesive. The back paste is provided with silicone oil release paper. The utility model realizes the fixing of the needle handle through the setting of medical pressure-sensitive adhesive, which solves the need to fix the needle handle with fingers and then paste the transparent dressing after the successful puncture of the indwelling needle in the prior art. During the process, the transparent dressing is easy to stick to the finger or easily Moving the needle handle causes it to fall off, and it is difficult to stick the needle handle when changing the dressing. At the same time, it solves the problem that after the puncture is successful, it is necessary to prepare an infusion sticker to fix the needle handle and then paste the transparent dressing. The operation is cumbersome and the remaining infusion If the stickers are not utilized, the problem of waste is caused, and the operation of the medical staff is more convenient. However, when the retained needle is taken out, the fixing adhesive tape will stick to the retained needle, which is not conducive to the nurse's pulling out the needle, and may even cause secondary injury to the patient.

The above-mentioned problems are urgent problems to be solved in this area.

Utility model content

The technical problem to be solved by the utility model is to provide an anti-adhesive retention needle, so as to avoid the stickiness of the retention needle and the fixing adhesive tape, and facilitate the needle removal by the nurse.

In order to solve the above-mentioned technical problems, the solution provided by the utility model is: an anti-adhesive retention needle, including a needle head and an anti-adhesion plate, the bottom surface of the anti-adhesion plate is provided with a placement slot corresponding to the needle head, and the needle head is arranged on In the placement groove, the outside of the anti-adhesive plate is provided with a fixed adhesive plaster to fix the anti-adhesive plate on the skin;

The anti-adhesion plate includes a connecting plate, and support plates are arranged symmetrically on both sides of the connecting plate, and the supporting plate and the connecting plate are arranged obliquely to each other.

As a further improvement of the utility model, ventilation holes are provided on the support plate and the fixing adhesive plaster.

As a further improvement of the utility model, the inclination angle of the support plate and the connecting plate is 150°-170°.

As a further improvement of the present utility model, the needle head is provided with a needle handle, and the anti-sticking plate is provided with a relief groove corresponding to the needle handle.

As a further improvement of the utility model, the end of the support plate in contact with the skin is arc-shaped.

As a further improvement of the utility model, the anti-sticking plate is made of transparent material.

The beneficial effects of the utility model:

The utility model has reasonable and simple structure and convenient operation. When the nurse uses the retained needle, insert the needle into the vein of the patient, and then put the anti-sticking plate on the top of the needle, so that the needle is located inside the placement groove, and then use it to fix the needle. The adhesive tape is attached to the release plate, and the needle and the release plate are stuck to the patient's skin. At the same time, the inclined support plate can reduce the contact area between the anti-adhesive plate and the patient's skin, effectively reduce the occurrence of sweating and foreign body sensation, and improve the patient's experience in use. When it is necessary to take out the retained needle, the fixed tape is torn off, and the anti-adhesive plate will be lifted together with the fixed adhesive tape, and the needle will not stick to the fixed adhesive tape through the protection of the anti-adhesive plate. Nurses only need to take out the needle from the patient's skin, no need to consider the situation of the needle sticking to the fixed adhesive tape, which greatly improves the convenience for nurses to take out the needle.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the utility model and implement it, but the examples given are not intended to limit the utility model.

With reference to shown in Fig. 1, be an embodiment of the present utility model, comprise needle head 1 and anti-adhesive plate 2, anti-adhesive plate 2 is by connecting plate 22 and supporting plate 23, and supporting plate 23 is arranged on the both sides of connecting plate 22 obliquely A slot 21 is provided on the bottom surface of the connecting plate 22 corresponding to the size of the needle head 1 . When using the retention needle, the nurse inserts the needle 1 into the patient's vein, and then puts the anti-adhesive plate 2 on the top of the needle 1 so that the needle 1 is located inside the placement groove 21, and then sticks it on the anti-adhesive plate with a fixed adhesive tape 2, stick the needle 1 and the anti-adhesive plate 2 on the patient's skin. At the same time, the inclined support plate 23 can reduce the contact area between the anti-adhesive plate 2 and the patient's skin, effectively reduce the occurrence of sweating and foreign body sensation, and improve the patient's experience in use. When it is necessary to take out the retained needle, the fixed adhesive tape is torn off, and now the anti-adhesive plate 2 will be lifted together with the fixed adhesive tape, and the needle 1 will not be stuck on the fixed adhesive tape through the protection of the anti-adhesive plate 2. The nurse only needs to take out the needle 1 from the patient's skin, and does not need to consider the situation that the needle 1 sticks to the fixed adhesive tape, which greatly improves the convenience for the nurse to take out the needle.

As shown in FIG. 1 , the support plate 23 and the fixing adhesive plaster are respectively provided with ventilation holes 24 , which can facilitate the circulation of air and avoid infection caused by sweating at the acupuncture points.

In this embodiment, the inclination angle of the support plate 23 and the connecting plate 22 is 150°-170°, usually 160°, which is the best angle, which can further reduce the contact area between the anti-adhesion plate 2 and the patient's skin. Improve patient experience.

As shown in Figure 2, in order to facilitate the nurse's needle insertion and needle removal, a needle handle 11 is provided on the needle head 1, and a relief groove 25 is provided on the anti-sticking plate 2 corresponding to the needle handle 11, and the nurse holds the needle by hand. The handle 11 is used to insert the needle 1 into the patient's vein.

In this embodiment, in order to further reduce the foreign body sensation of the patient, the end of the support plate 23 in contact with the skin is set in an arc shape. Compared with the ordinary right-angle shape, the contact between the arc shape and the skin is more accurate. Round, can reduce the foreign body sensation of patients.

In this embodiment, the anti-adhesive plate 2 is made of transparent material, so that the nurse can observe the situation of the needle 1 in real time through the transparent material.

In actual work, the size of the placement groove 21 is usually slightly larger than the size of the needle 1, so as to avoid lifting the needle 1 when the anti-adhesive plate 2 is lifted. When the nurse takes the needle, it only needs to tear off the fixed adhesive tape, and the anti-adhesive plate 2 is lifted together with the fixed adhesive tape, and the nurse only needs to take out the needle head 1 through the needle handle 11. Thereby, the sticking between the needle head 1 and the fixing tape can be avoided, and the convenience of taking out the needle can be improved.
