Technical Field
[0001] The utility model relates to the technical field of indwelling needle fixation, in particular to an indwelling needle auxiliary fixation structure. Background Art
[0002] Indwelling needles are commonly used medical devices in nursing work. They are easy to use and can reduce the number of punctures on patients, thereby reducing repeated punctures during clinical infusions, reducing the patient's puncture pain and the workload of clinical nursing staff. Therefore, they have been widely used in today's clinical practice.
[0003] At present, the indwelling needle is usually composed of a puncture needle, an indwelling needle and an infusion catheter. When in use, the user first inserts the puncture needle and the indwelling needle into the patient's injection site, then guides the indwelling needle into the patient's blood vessel through the puncture needle guide, and finally withdraws the puncture needle, leaving the indwelling needle in the patient's blood vessel and fixing it with a patch. Since the patch is used to fix the indwelling needle on the patient's skin, the patch is in direct contact with the patient's skin. This setting is easy to cause redness, swelling and allergies in patients with sensitive skin.
[0004] Therefore, we propose an indwelling needle auxiliary fixation structure to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of the utility model is to provide an auxiliary fixing structure for an indwelling needle to solve the problem proposed in the above background technology that since the dressing is used to fix the indwelling needle on the patient's skin, the dressing is in direct contact with the patient's skin. This setting is easy to cause redness, swelling and allergies in patients with sensitive skin.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary fixing structure for an indwelling needle, comprising an outer plastic packaging component, in which an injection assembly is placed in the inner cavity of the outer plastic packaging component, and the outer plastic packaging component is arranged to limit and fix the outer wall of the injection assembly when the injection assembly is in use.
[0007] Preferably, the outer plastic packaging assembly includes a retention structure and a puncture needle arranged at one end of the retention structure, and an infusion structure is arranged at one end of the outer wall of the retention structure.
[0008] Preferably, the outer plastic packaging component includes a U-shaped cover sheet and angled slots symmetrically arranged around the outer wall of the U-shaped cover sheet.
[0009] Preferably, an annular leakage groove is provided in the middle of the U-shaped cover plate, and a transparent blocking cover is fixedly installed around the upper end of the notch of the annular leakage groove.
[0010] Preferably, the diameter of the annular leakage groove is set smaller than the diameter of the transparent blocking cover, and the annular leakage groove is used to wrap the needle assembly in its inner cavity.
[0011] Preferably, the infusion structure includes a long connecting tube and an elastic band bound to one side of the outer surface of the long connecting tube.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The medical staff takes out the indwelling needle and ties an elastic band on the upper part of the long tube connecting the indwelling needle. After the indwelling needle is successfully punctured, the elastic band is first used to wrap around the indwelling needle, and the U-shaped cover is used to drive the transparent cover to cover the puncture site. Then, the elastic band is wrapped around the edge of the transparent cover, and then the elastic band is continued to be wrapped, and the elastic band is stuck in the angled slot. According to the situation, it is wrapped several times to ensure that it is fixed and then stopped to prevent the tube from falling off. The setting of the elastic band replaces the use of patch fixation to reduce the discomfort caused by the use of indwelling needle fixation due to skin sensitivity.
[0014] 2. Medical staff cut the outer plastic packaging component in the middle with scissors and stack them together to use as a skin protection shell after successful puncture of the indwelling needle.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example 1: Please refer to Figure 1-4 An auxiliary fixing structure for an indwelling needle includes an outer plastic packaging component 1, in which an acupuncture component 2 is placed in the inner cavity of the outer plastic packaging component 1. The outer plastic packaging component 1 is configured to limit and fix the outer wall of the acupuncture component 2 when the acupuncture component 2 is in use.
[0022] The outer plastic packaging assembly 1 includes a retention structure 21 and a puncture needle 22 arranged at one end of the retention structure 21 , and an infusion structure 23 is arranged at one end of the outer wall of the retention structure 21 .
[0023] The diameter of the annular leakage groove 13 is set to be smaller than the diameter of the transparent cover 14. The annular leakage groove 13 is used to wrap the needle assembly 2 in its inner cavity to limit the placement of the needle assembly 2.
[0024] The infusion structure 23 includes a connecting long tube 231 and an elastic band 232 bound to one side of the outer surface of the connecting long tube 231. The elastic band 232 is used to bind the retention structure 21 together with the outer plastic packaging component 1 to the upper end of the patient's skin, replacing the dressing to play a fixing role. Since the transparent baffle 14 is fixedly installed on the upper end of the U-shaped cover piece 11, when the elastic band 232 is wrapped around the transparent baffle 14, that is, the elastic band 232 is pressed around the upper end of the U-shaped cover piece 11, the stability of the winding of the elastic band 232 is improved by embedding the elastic band 232 into the inner cavity of the angled slot 12.
[0025] In this embodiment: the medical staff first cuts four notches on the edge of the outer packaging of the indwelling needle, i.e., on both sides of the U-shaped cover sheet 11, as angled slots 12. The angled slots 12 are used to assist the elastic bandage to better fix the indwelling needle. The indwelling needle is taken out, and an elastic bandage 232 is tied on the upper part of the indwelling needle connecting long tube 231, and then placed in a sterile tray for standby use. After the indwelling needle puncture is successful, the elastic bandage 232 is first used to surround the indwelling needle, and the U-shaped cover sheet 11 is used to drive the transparent baffle 14 to cover the puncture site. Then, after the elastic bandage 232 is wrapped around the edge of the transparent baffle 14, it is continued to be wrapped, and the elastic bandage 232 is stuck in the angled slot 12. According to the situation, it is stopped after several turns of winding to determine whether it is fixed to prevent the tube from falling off. The elastic bandage 232 is set instead of the dressing fixation to reduce the discomfort caused by the use of indwelling needle fixation due to skin sensitivity.

[0027] An annular leakage groove 13 is provided in the middle of the U-shaped cover 11, and a transparent blocking cover 14 is fixedly installed around the upper end of the notch of the annular leakage groove 13. The transparent blocking cover 14 is used to accommodate the needle assembly 2 in its cavity to improve the safety of the needle assembly 2.
[0028] In this embodiment: medical staff cuts the outer plastic packaging component 1 in the middle with scissors and stacks them together to use as a skin protection shell after successful puncture of the indwelling needle. The cutting effect can be used to adjust the size of the outer plastic packaging component 1 according to the puncture site when in use.
[0029] Working principle: Medical staff takes out the indwelling needle, ties the elastic band 232 on the upper part of the indwelling needle connecting long tube 231, and after the indwelling needle puncture is successful, first use the elastic band 232 to wrap around the indwelling needle, use the U-shaped cover 11 to drive the transparent baffle 14 to cover the puncture site, and then wrap the edge of the transparent baffle 14 with the elastic band 232, continue to wrap it, and clamp the elastic band 232 in the angled slot 12, wrap it several times to make sure it is fixed and stop to prevent the tube from falling off.
