[0002] Puncture drainage tubes are commonly used medical devices in clinical practice, mainly used to drain the accumulated fluids in the body (such as pus, blood, tissue fluid, etc.) by puncturing and placing a drainage tube, so as to achieve the purpose of diagnosis, treatment or symptom relief. And the puncture drainage tube fixation device is a medical device used to fix the puncture drainage tube in the patient's body or on the body surface to ensure the stability and effectiveness of the drainage tube.

[0003] Common fixation devices on the market at present include tape fixation, buckle fixation, adhesive buckle fixation, etc. Among them, the adhesive buckle fixation mainly includes an adhesive patch, a connection surface is arranged on the adhesive patch, a cotton strip is arranged in the middle of the connection surface, and fixing patches are arranged on both sides of the cotton strip. When in use, the puncture drainage tube is placed on the cotton strip and then fixed around by the fixing patches on both sides.

[0004] However, when the fixing patch fixes the puncture drainage tube, it will exert a certain pressure, so the puncture drainage tube will exert a certain pressure on the patient's skin, which is likely to cause the skin at the squeezed position to be airtight and breed bacteria, resulting in pressure sores. And the puncture drainage tube is deformed under extrusion, which is likely to cause the puncture drainage tube to be blocked, affecting infusion.

[0005] Therefore, it is necessary to design a puncture drainage tube fixation device that can prevent skin compression and will not cause the puncture drainage tube to be squeezed and blocked to solve the problem. Summary of the Utility Model

Moreover, the pressure sore patch has good overall air permeability and contains antibiotic drugs that inhibit bacteria, effectively preventing infection. The puncture drainage tube passes through the limiting mechanism, and can also prevent being constricted and flattened by the first fixed patch and the second fixed patch. The first fixed patch and the second fixed patch are limited through the central arc groove and the side arc grooves to prevent displacement. Moreover, the friction with the puncture drainage tube is increased through a plurality of inclined arc-shaped rubber blocks.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Embodiment 1 is given by Figure 1-6 The puncture drainage tube fixing device includes a fixing mechanism fixed on the pressure ulcer patch 1. The pressure ulcer patch 1 is composed of an adhesive base, an absorption layer, a drug layer, a breathable layer and a protective layer from bottom to top;

[0027] Among them, the adhesive base is one of medical pressure-sensitive adhesive or polyurethane material, the absorption layer is made of foam sponge material, the drug layer is silver sulfadiazine, the breathable layer is one of microporous film or polyurethane transparent film, and the protective layer is one of PET film or PE film or PP film.

[0028] Specifically, the pressure ulcer patch 1 is adhered to the puncture wound of the patient, and the puncture drainage tube is limited by the fixing mechanism. The fixing mechanism is adhered to the patient through the pressure ulcer patch 1, so that the pressure on the skin is relatively small when fixing the puncture drainage tube, preventing pressure sores on the skin caused by excessive pressure. Moreover, the overall air permeability of the pressure ulcer patch 1 is good, and there is an antibiotic drug for inhibiting bacteria inside, effectively preventing infection.

[0029] In this embodiment, the fixing mechanism includes a connecting bottom surface 2 fixed to the top of the pressure ulcer patch 1. An adhesive surface patch 3 is fixed to the upper part of the connecting bottom surface 2. A limiting mechanism 6 is fixed to the middle part of the adhesive surface patch 3. A fixing patch one 4 and a fixing patch two 5 are respectively fixed on both sides of the limiting mechanism 6. A through hole 51 is formed near the middle of the fixing patch two 5 close to the limiting mechanism 6. A magic tape structure is arranged between the adhesive surface patch 3, the fixing patch one 4 and the fixing patch two 5 for bonding and fixing.

[0030] Specifically, the puncture drainage tube is placed on the limiting mechanism 6. The fixing patch one 4 and the fixing patch two 5 are grasped. The fixing patch one 4 passes through the through hole 51 around the limiting mechanism 6 and is bonded to the adhesive surface patch 3 through the magic tape structure. The fixing patch two 5 passes around the limiting mechanism 6 and is bonded to the adhesive surface patch 3 through the magic tape structure to limit the puncture drainage tube.

[0031] Among them, the magic tape structure includes an adhesive surface and a hook surface. The adhesive surfaces are respectively fixed to the fronts of the fixing patch one 4 and the fixing patch two 5, and the hook surface is fixed to the front of the connecting bottom surface 2.

[0032] In this embodiment, the limiting mechanism 6 includes a fixing seat 61 fixed to the middle of the adhesive surface patch 3. An arc groove 611 is formed at the top of the fixing seat 61. A plurality of arc-shaped rubber blocks 613 are evenly fixed to the bottom of the arc groove 611. A baffle 612 is fixed to the side of the fixing seat 61. An arc-shaped cover 62 is hinged to one side of the top of the fixing seat 61. A central arc groove 621 is formed in the middle of the outer surface of the arc-shaped cover 62. Side arc grooves 622 are formed on the outer surfaces of both ends of the arc-shaped cover 62.

[0033] Specifically, open the arc-shaped cover 62, place the puncture drainage tube into the arc-shaped groove 611 of the fixed seat 61, make contact with multiple arc-shaped rubber blocks 613, close the arc-shaped cover 62 with the fixed seat 61, and the arc-shaped cover 62 is limited by the baffle 612; then pick up the first fixing patch 4 and the second fixing patch 5. The first fixing patch 4 passes through the through hole 51 around the middle arc groove of the arc-shaped cover 62 and is adhesively bonded to the adhesive surface patch 3 through a magic tape structure. The second fixing patch 5 passes around the side arc groove 622 of the arc-shaped cover 62 and is adhesively bonded to the adhesive surface patch 3 through a magic tape structure to limit the puncture drainage tube. It is protected by the arc-shaped cover 62 and the fixed seat 61, and can also prevent being constricted and flattened by the first fixing patch 4 and the second fixing patch 5. The first fixing patch 4 and the second fixing patch 5 are limited by the central arc groove 621 and the side arc groove 622 to prevent displacement. Moreover, the multiple inclined arc-shaped rubber blocks 613 increase the friction force with the puncture drainage tube, and when the puncture drainage tube is pulled, a greater resistance can be generated to reduce the pain involved in the puncture wound.

[0034] Embodiment 2: On the basis of Embodiment 1, the side arc grooves 622 on both sides of the arc-shaped cover 62 are connected through an extrusion mechanism. The extrusion mechanism includes an arc-shaped plate 63 and an arc-shaped extrusion plate 632. Connecting blocks 633 are fixed on both sides between the arc-shaped plate 63 and the arc-shaped extrusion plate 632, and the connecting blocks 633 penetrate through the positions of the side arc grooves 622 of the arc-shaped cover 62.

[0035] Specifically, by setting an extrusion mechanism on the arc-shaped cover 62, the smaller puncture drainage tube can be limited and protected. Place the puncture drainage tube into the arc-shaped groove 611 of the fixed seat 61, make contact with multiple arc-shaped rubber blocks 613, close the arc-shaped cover 62 with the fixed seat 61, pick up the first fixing patch 4 and the second fixing patch 5. When the first fixing patch 4 passes through the through hole 51 around the middle arc groove of the arc-shaped cover 62 and is adhesively bonded to the adhesive surface patch 3 through a magic tape structure, and the second fixing patch 5 passes around the side arc groove 622 of the arc-shaped cover 62 and is adhesively bonded to the adhesive surface patch 3 through a magic tape structure, the second fixing patch 5 squeezes the arc-shaped extrusion plate 632, so that the connecting block 633 drives the arc-shaped plate 63 to move downward and contact and squeeze the puncture drainage tube, so that the puncture drainage tube in the fixed seat 61 is limited and fixed. Cooperating with the multiple inclined arc-shaped rubber blocks 613, it further prevents the drainage tube from involving the puncture wound when being pulled.

[0036] Among them, a limiting arc groove 631 is formed on the outer surface of the middle part of the arc-shaped extrusion plate 632. When the second fixing patch 5 passes around the side arc groove 622 of the arc-shaped cover 62 and is adhesively bonded to the adhesive surface patch 3 through a magic tape structure, the second fixing patch 5 squeezes the arc-shaped extrusion plate 632 and contacts and limits it with the limiting arc groove 631.

[0037] Working principle:

[0038] During use, paste the pressure ulcer dressing 1 beside the puncture wound of the patient. Then open the arc-shaped cover 62, place the puncture drainage tube into the arc-shaped groove 611 of the fixing seat 61, make contact with multiple arc-shaped rubber blocks 613, close the arc-shaped cover 62 with the fixing seat 61, and the arc-shaped cover 62 is limited by the baffle 612;

[0039] Then, pick up the first fixing patch 4 and the second fixing patch 5. The first fixing patch 4 passes through the through hole 51 around the middle arc groove of the arc-shaped cover 62 and is adhesively bonded to the adhesive surface patch 3 through the magic tape structure. The second fixing patch 5 passes around the side arc groove 622 of the arc-shaped cover 62 and is adhesively bonded to the adhesive surface patch 3 through the magic tape structure to limit the puncture drainage tube;

[0040] The fixing mechanism is adhesively bonded to the patient's body through the pressure ulcer dressing 1, so that when fixing the puncture drainage tube, the pressure on the skin is relatively small, preventing pressure sores from occurring due to excessive pressure. Moreover, the overall air permeability of the pressure ulcer dressing 1 is good, and there is an antibiotic drug for inhibiting bacteria inside, effectively preventing infection. The puncture drainage tube is placed in the limiting mechanism 6 and is protected by the arc-shaped cover 62 and the fixing seat 61, and can also prevent being constricted and flattened by the first fixing patch 4 and the second fixing patch 5. The first fixing patch 4 and the second fixing patch 5 are limited by the central arc groove 621 and the side arc groove 622 to prevent displacement. Moreover, the friction with the puncture drainage tube is increased by multiple inclined arc-shaped rubber blocks 613. When the puncture drainage tube is pulled, a large resistance can be generated, reducing the pain involved in the puncture wound;

[0041] An extrusion mechanism is arranged on the arc-shaped cover 62 to limit and protect the relatively small puncture drainage tube. Place the puncture drainage tube into the arc-shaped groove 611 of the fixing seat 61, make contact with multiple arc-shaped rubber blocks 613, close the arc-shaped cover 62 with the fixing seat 61, pick up the first fixing patch 4 and the second fixing patch 5. When the first fixing patch 4 passes through the through hole 51 around the middle arc groove of the arc-shaped cover 62 and is adhesively bonded to the adhesive surface patch 3 through the magic tape structure, and the second fixing patch 5 passes around the side arc groove 622 of the arc-shaped cover 62 and is adhesively bonded to the adhesive surface patch 3 through the magic tape structure, the second fixing patch 5 squeezes the arc-shaped extrusion plate 632 to make contact with the limiting arc groove 631 for limitation. Thus, the connecting block 633 drives the arc-shaped plate 63 to move downward to contact and squeeze the puncture drainage tube, so that the puncture drainage tube in the fixing seat 61 is limited and fixed. Cooperating with multiple inclined arc-shaped rubber blocks 613, it further prevents the drainage tube from involving the puncture wound when being pulled.
