[0002] An intravenous catheter is a commonly used medical device. Placing the catheter in the patient's veins can reduce the pain caused by repeated punctures to the patient. Therefore, intravenous catheters are widely used in clinical practice.

[0003] When medical staff successfully puncture a patient's vein using an intravenous needle, a patch is used in related technologies to fix the needle on the skin to prevent the needle from shifting or falling off. Intravenous needle patches are usually transparent patches, which are airtight and prone to allergies. Especially for infants or children, the allergy problem caused by transparent patches is more prominent.

[0004] For this reason, a pediatric infusion fixing plate has appeared in the prior art. By fixing the palm on the fixing plate, the problem of needle displacement or falling off due to hand movement of infants or children can be prevented. However, this kind of fixing plate is usually made of hard materials. After the palm is fixed on the fixing plate, the hand cannot move freely, and the patient's comfort is affected. In addition, using the fixing plate to fix the palm may cause infection problems due to the exposure of the indwelling needle puncture point, and may also cause the indwelling needle to stick to the wall. After the indwelling needle is attached to the blood vessel wall, the indwelling needle is prone to poor liquid circulation during the infusion process, making it difficult to continue using the indwelling needle.

[0005] Therefore, providing a breathable, non-allergenic and comfortable-to-use indwelling needle fixture is a technical problem that needs to be urgently solved by those skilled in the art. Utility Model Content

[0035] In the related art, transparent dressings are used to fix indwelling needles, which have the problems of being airtight and prone to allergies. Especially for infants or children, the allergy problem caused by transparent dressings is more prominent; or in the related art, a child infusion fixing plate is used to fix the entire palm to prevent the needle from shifting or falling off. However, after using the child infusion fixing plate, there are still technical problems that the user's hand cannot move and is prone to infection and wall adhesion. To this end, the present application provides an indwelling needle fixing part, which is made of elastic bandage, so that the fixing part can not only reduce the hidden danger of the indwelling needle sticking to the wall, thereby extending the use time of the indwelling needle, but also has the advantages of good air permeability and not easy to cause allergies.

[0036] The following is combined with Figures 1 to 8 , the indwelling needle fixing device provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.

[0037] The indwelling needle fixing member of this embodiment is used to fix the indwelling needle 210 punctured on the back of the hand.

[0038] The indwelling needle fixing device of this embodiment includes a fixing device body 110. The fixing device body 110 has a first fixing portion 111 and a second fixing portion 112. When the fixing device body 110 is wrapped around the indwelling needle 210 on the patient's hand, the first fixing portion 111 and the second fixing portion 112 form a through hole 120, and an opening 130 is formed between the first fixing portion 111 and the second fixing portion 112. The through hole 120 is for the patient's palm and four fingers to pass through, and the opening 130 is for the patient's thumb to pass through. Figure 1 to Figure 7 shown.

[0039] This structure allows the indwelling needle fixing piece to match the shape of the human hand, which not only fixes the indwelling needle but also facilitates hand movements and is highly comfortable.

[0040] Preferably, the fixing body 110 is made of an elastic bandage. The elastic bandage is also called an elastic bandage or an elastic self-adhesive bandage, which is a product in the prior art and its structure is not described in detail. The elastic bandage is used in the medical field and has the advantages of being breathable, elastic, self-adhesive and comfortable.

[0041] The indwelling needle fixing piece of the present embodiment is made of an elastic bandage having an uneven structure on its surface. The uneven structure is used to fix the indwelling needle, which not only reduces the problem of sticking to the wall, thereby extending the use time of the indwelling needle, but also prevents the indwelling needle fixing piece from completely fitting against the skin when the indwelling needle fixing piece is wrapped on the hand, thereby making the indwelling needle fixing piece have the advantages of good air permeability and not prone to allergy problems.

[0042] That is, the indwelling needle fixing piece of this embodiment can solve the technical problems of indwelling needle dressings in related technologies being airtight and prone to allergies, and infusion fixing plates being low in comfort, prone to infection and sticking to the wall.

[0043] Preferably, the width ratio of the first fixing portion 111 to the second fixing portion 112 is 1 to 2:5. In the indwelling needle fixing device of this embodiment, the width ratio of the first fixing portion 111 to the second fixing portion 112 is 1 to 2:5, which can not only ensure the fixing and bandaging effect of the indwelling needle, but also prevent obvious foreign body sensation at the base of the thumb and the palm, and facilitate hand movement; at the same time, when the first fixing portion 111 and the second fixing portion 112 are an integrated structure, it can also avoid the problem that the pulling force of the first fixing portion 111 on the second fixing portion 112 is too large, causing tearing at the opening 130, and the pulling force in the radial direction of the fixing body 110 is too large, resulting in excessive pressure on the indwelling needle by the second fixing portion 112, affecting the patient's comfort when using it.

[0044] Preferably, the indwelling needle fixing member of this embodiment can be made into a sleeve-like structure, such as Figure 1 to Figure 4 The sleeve-shaped indwelling needle fixing piece can be directly sleeved on the indwelling needle on the hand when in use, which has the advantage of being easy to use.

[0045] Preferably, the indwelling needle fixing member of this embodiment can also be made into a strip or belt structure, such as Figure 5 to Figure 7 As shown. When using the strip or band-shaped indwelling needle fixing piece, it is necessary to wrap it around the indwelling needle on the hand. Since the elastic bandage has its own adhesiveness, it can be fixed by its own adhesiveness without using additional tape. The strip or band-shaped indwelling needle fixing piece has the advantage of being simple to produce and manufacture.

[0046] When the indwelling needle fixing piece is a strip or band structure, first, the fixing piece body 110 at the end without the opening 130 is covered on the indwelling needle 210, and then the second fixing part 112 is wrapped around the end on the palm close to the wrist, and the end of the second fixing part 112 can be fixed by the viscosity of the elastic bandage itself; then the first fixing part 111 is wrapped around the end on the palm close to the finger, and the end of the first fixing part 111 can be fixed by the viscosity of the elastic bandage itself.

[0047] According to a preferred embodiment, the length of the opening 130 satisfies: 1 / 4L≤L1≤2 / 3L, where L is the circumferential length of the fixing body 110, and L1 is the length of the opening 130 along the circumferential direction of the fixing body 110. Preferably, the length of the opening 130 at the back of the hand is shorter than the length of the opening 130 at the palm, that is, the opening 130 is mainly located at the palm, such as Figure 2 (palm) and Figure 3 (Back of hand) shown.

[0048] The indwelling needle fixing device of the preferred technical solution of the present embodiment limits the length of the opening 130 and makes the opening 130 mainly located in the palm part, so that the first fixing part 111 can mainly generate a pulling force on the second fixing part 112 located on the back of the hand, thereby ensuring that the first fixing part 111 has a suitable pulling force on the second fixing part 112, so that the pulling force maintains a suitable component in the radial direction of the fixing device body 110, avoiding the problem that the component force is too large, causing the user to have a noticeable squeezing feeling, and should also avoid the problem that the component force is too small, resulting in a loose fixation of the indwelling needle 210.

[0049] According to a preferred embodiment, when the indwelling needle fixing member is a sleeve-shaped structure, the first fixing portion 111 and the second fixing portion 112 may be an integrated structure or a split structure.
