Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an indwelling needle. Background Art

[0002] In the medical field, an indwelling needle is a commonly used infusion tool that can remain in the patient's blood vessels for a long time, avoiding the pain caused by repeated punctures to the patient. However, in the process of using an indwelling needle, there are some technical problems that need to be solved.

[0003] Children are one of the main groups who use indwelling needles, but because they are afraid of needles and pain, they often move around after acupuncture, causing the indwelling needles to fall off. This not only increases the workload of medical staff, but also may affect the treatment of patients.

[0004] At present, when medical staff fix the indwelling needle after acupuncture, they usually use tape to wrap directly around the needle handle and the skin of the indwelling needle. However, the tape wrapping method is too slow and it is easy to fall off when the child resists and moves before the tape is wrapped.

[0005] Therefore, how to provide an indwelling needle that can quickly fix the indwelling needle on the back of the hand after acupuncture and reduce the chance of falling off is a technical problem that needs to be solved at present. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide an indwelling needle to overcome the deficiencies in the above-mentioned prior art.

[0007] The utility model provides a technical solution to the above-mentioned technical problems as follows: an indwelling needle, comprising an indwelling needle body and a limiting plate; the indwelling needle body is detachably connected to the limiting plate, an adhesive layer is provided at the bottom of the limiting plate, a release film is covered on the outside of the adhesive layer, a pulling belt is provided at the bottom of the release film, and the pulling belt is connected to the release film on the side of the needle tip of the indwelling needle body close to the needle tip.

[0008] The beneficial effects of the utility model are as follows: when in use, the indwelling needle body is inserted into the vein at the back of the patient's hand, and then the pulling belt is pulled backward to separate the release film from the adhesive layer, and the limiting sheet can be quickly attached to the patient's arm to fix the indwelling needle body on the back of the child's hand, which can prevent the indwelling needle body from falling off due to the child's movement before the medical staff fixes it with tape after acupuncture. In addition, since the sticking area of ​​the limiting sheet is large and the friction force is large, and the indwelling needle body is arranged on the limiting sheet, the risk of the indwelling needle body being pulled out after being wrapped with medical tape can be greatly reduced;

[0009] The setting of the release film can prevent the limiting piece from sticking to the back of the hand and making it impossible to complete the acupuncture during the acupuncture process. It can also protect the adhesive layer to prevent impurities from sticking to it and affecting the adhesive effect. The setting of the pulling belt makes it easy to quickly tear off the release film after the acupuncture is completed. When the indwelling needle body needs to be removed, you only need to remove the indwelling needle body from the limiting piece, and then tear off the limiting piece.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the needle head of the indwelling needle body includes a needle tube, a needle handle and a holding piece arranged in the middle of the needle handle.

[0012] Furthermore, the upper end surface of the limiting plate is located at the front end and the rear end of the limiting plate, and a first support seat and a second support seat are respectively provided. One end of the needle tube passes through the first support seat, and one end of the needle handle passes through the second support seat. The needle tube and the needle handle rotate in the first support seat and the second support seat respectively. A slot is opened above the second support seat, and the width of the slot is greater than the thickness of the holding plate.

[0013] Furthermore, a side wall of the notch is provided with a rounded corner near one end of the holding piece.

[0014] Furthermore, the length of the pulling belt is greater than the length of the limiting piece.

[0015] Furthermore, a medical tape roll is connected to one side of the limiting plate, and an end of the medical tape roll is connected to one side of the limiting plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] like Figure 1 to Figure 5 As shown, embodiment 1, an indwelling needle, includes an indwelling needle body 1 and a limiting plate 2; the indwelling needle body 1 is detachably connected to the limiting plate 2, an adhesive layer is provided at the bottom of the limiting plate 2, the outer side of the adhesive layer is covered with a release film 23, a pulling belt 24 is provided at the bottom of the release film 23, and the pulling belt 24 is connected to the release film 23 near the needle tip side of the indwelling needle body 1.

[0025] When in use, the indwelling needle body 1 is inserted into the vein at the back of the patient's hand, and then the pulling belt 24 is pulled back to separate the release film 23 from the adhesive layer. The limiting sheet 2 can be quickly attached to the patient's arm to fix the indwelling needle body 1 on the back of the child's hand, which can prevent the indwelling needle body 1 from falling off due to the child's movement before the medical staff fixes it with tape after acupuncture. In addition, since the limiting sheet 2 has a large adhesive area and a large friction force, and the indwelling needle body 1 is arranged on the limiting sheet 2, the risk of the indwelling needle body 1 being pulled out after being wrapped with medical tape can be greatly reduced;

[0026] The setting of the release film 23 can prevent the limiting plate 2 from sticking to the back of the hand and making it impossible to complete the acupuncture during the acupuncture process, and can also protect the adhesive layer to prevent impurities from sticking to it and affecting the adhesive effect; the setting of the pulling belt 24 makes it easy to quickly tear off the release film 23 after the acupuncture is completed; when the indwelling needle body 1 needs to be removed, it is only necessary to remove the indwelling needle body 1 from the limiting plate 2, and then tear off the limiting plate 2.

[0027] Embodiment 2: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0028] The needle head of the indwelling needle body 1 comprises a needle tube 11, a needle handle 12 and a holding piece 13 arranged in the middle of the needle handle 12. The holding piece 13 is arranged to facilitate holding the indwelling needle body 1 for acupuncture.

[0029] Embodiment 3, this embodiment is a further improvement on the basis of embodiment 2, and its details are as follows:

[0030] The upper end surface of the limiting plate 2 is located at the front and rear ends of the limiting plate 2, and a first support seat 21 and a second support seat 22 are respectively provided. One end of the needle tube 11 passes through the first support seat 21, and one end of the needle handle 12 passes through the second support seat 22. The needle tube 11 and the needle handle 12 rotate in the first support seat 21 and the second support seat 22 respectively. A slot 221 is opened above the second support seat 22, and the width of the slot 221 is greater than the thickness of the holding plate 13.

[0031] After acupuncture, rotate the holding piece 13 to make the holding piece 13 deviate from the slot 221. The holding piece 13 is intercepted by the second support seat 22, and the indwelling needle body 1 will not be accidentally pulled out. At this time, the medical tape can be manually wrapped. When the indwelling needle body 1 needs to be removed, it is only necessary to rotate the holding piece 13 to align the holding piece 13 with the slot 221, and the indwelling needle body 1 can be pulled out along the slot 221.

[0032] Embodiment 4: This embodiment is a further improvement on the basis of embodiment 3, and its details are as follows:

[0033] The side wall of the notch 221 is provided with a rounded corner 222 near one end of the holding piece 13 so as to guide the holding piece 13 and facilitate the holding piece 13 to enter the notch 221 better.

[0034] Embodiment 5: This embodiment is a further improvement based on any one of Embodiments 1 to 4, and its details are as follows:
