DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0031] During the care of the indwelling tube, the first thing to consider is the waterproofing issue. The indwelling tube needs to be retained for a long time. During this process, it is inevitable that the indwelling tube will be contaminated by daily activities, such as bathing or sweating. This will also cause the gauze and tape that fix the indwelling tube to fail. If it is not replaced in time, there will be a risk of the indwelling tube falling off, and it may also breed bacteria. Frequent replacement of the gauze and tape is a burden for patients.

[0032] Embodiment 1:

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, the indwelling tube nursing auxiliary device is composed of a fixing member 100, a waterproof member 200 and an absorbent member 300. The fixing member 100 is used to fix the tube body and the tube head of the indwelling tube. The fixing member 100 is a cylindrical structure with a thickness of 0.5-1 cm. The fixing member 100 has a rounded rectangular through hole 110 at the center. The through hole 110 is used for the indwelling tube to pass through. The through hole 110 is connected to a tube groove 120. The tube groove 120 is used to fix the tube body of the indwelling tube. The tube groove 120 is an annular ring located outside the through hole 110. shaped groove and several strip grooves connecting the annular groove and the through hole 110. In the present embodiment, three strip grooves are respectively distributed in a fan shape on the left and right sides (the two sides opposite to the short sides of the through hole 100), one end of the strip groove is connected to the annular groove, and the other end is connected to the through hole 110, and the depth of the annular groove and the strip groove is the same; in the present embodiment, one of the strip grooves is perpendicular to the short side of the through hole 110 and is located at the center of the short side, and the other two strip grooves are respectively located at the two corners of the short side of the through hole 110.

[0034] The indwelling tube passes through the through hole 110, and then is inserted into any strip groove, and is inserted into the annular groove in sequence along the strip groove. According to the length of the tube body, the last distance of the indwelling tube body close to the tube head (usually a distance slightly longer than the length of the strip groove, which does not affect the fixing effect to some extent) is inserted into the direction of the through hole 110 along the nearest strip groove along the travel route. After insertion, the tube head of the indwelling tube is again located at the through hole 110. There is an upward protrusion outside the long side of the through hole 110 and inside the annular groove to form a tube head clamping groove 130, and the tube head of the indwelling tube is clamped into the tube head clamping groove 130 for fixing.

[0035] While fixing the tube body and the tube head, the fixing part 100 is also fixed on the surface of the skin, and then the waterproof part 200 is covered on the fixing part 100. The main body of the waterproof part 200 is a waterproof shell 210, which is a cylindrical shell structure with an opening at the bottom. The edge below the waterproof shell 210 is connected to a waterproof edge 220. The waterproof shell 210 and the waterproof edge 220 are integrally formed. The waterproof edge 220 is relatively provided with a pair of strap holes 230, and the strap holes 230 are used to connect straps. When in use, the waterproof shell 210 is covered on the fixing part 100, and the fixing part 100 is wrapped inside the waterproof shell 210. At this time, the waterproof edge 220 is attached to the skin, and finally the water retaining part 200 is fixed on the skin by a strap. Preferably, the waterproof part 200 is made of soft materials such as silicone, which will be more comfortable to use.

[0036] In order to solve the problems of fluid seepage and sweating at the connection between the indwelling tube and the skin, an absorbent 300 is added in the present embodiment. The absorbent 300 is a highly absorbent dressing, such as polyvinyl alcohol foam. The thickness of the absorbent 300 is about 2-5 mm. There is an absorbent through hole 310 of the same size and shape as the through hole 110 in the center of the absorbent 300. A groove 320 is vertically provided in the middle of the long side of one side of the absorbent through hole 310. The groove 320 allows the indwelling tube body to pass through. The advantage of this design is that the absorbent 300 can be replaced. The groove 320 is passed through the indwelling tube body. The final position of the absorbent 300 is located on the lower surface of the fixing member 100, so that the absorbent through hole 310 and the through hole 110 overlap. When replacing, the fixing member 100 is slightly lifted to remove the used absorbent 300 and replace it with a new absorbent 300.

[0037] In order to facilitate observation of the liquid absorption of the absorbent 300, the fixing member 100 and the waterproof member 200 are made of transparent materials.

[0038] Embodiment 2:

[0039] On the basis of Example 1, the air permeability of the waterproof component 200 is taken into consideration so that the humidity inside the waterproof component 200 will not be too high due to sweating, which will lead to problems such as bacterial growth.

[0040] like Figure 4 and Figure 5 As shown, a plurality of air holes 240 are provided on the upper surface of the waterproof shell 210. The air holes 240 are circular through holes. In order not to affect the waterproof sealing performance, a layer of air permeable membrane 250 is fixed on the inner surface of the upper surface of the waterproof shell 210. The air permeable membrane 250 is made of a waterproof but breathable material.

[0041] Embodiment 3:

[0042] Considering the position of the arm where the indwelling tube is located, for patients with small arms, the circular shape may not have enough area, resulting in poor waterproof effect. Although the fixing part 100 and the waterproof part 200 can be made of soft silicone material, which has a certain degree of flexibility, they can be wrapped around the arm for use.

[0043] The present embodiment optimizes the design by setting it to a rectangular shape, whose long side can be placed along the arm position, and its sealing and waterproof performance will be better. At the same time, the fixing part 100 and the waterproof part 200 are set into an integrated structure, which is more convenient to use.

[0044] like Figure 6 and Figure 7 As shown, the indwelling tube care auxiliary device is a fixed waterproof integrated part 400, the main body of the fixed waterproof integrated part 400 is an internally hollow shell 410, the shell 410 is a rounded rectangular shape, an upper through hole 411 is provided at the center of the upper surface of the shell 410, and two opposite sides of the upper through hole 411 (both sides of the short sides) have tube head grooves 412 formed by the upper surface being recessed inwardly, the tube body is received in the shell 410, and the tube head is fixed in the tube head groove 412.

[0045] There is a lower through hole 413 at the center of the lower surface of the shell 410. The upper through hole 411 and the lower through hole 413 are located at the same longitudinal position and are both in a rounded rectangular shape, which is convenient for the indwelling tube body and tube head to pass through. There is an absorber groove 414 formed by the lower surface being recessed inward around the lower through hole 413. The absorber groove 414 is used to accommodate the absorber 300. There is a circle of silicone ring 415 at a distance from the absorber groove 414 outside the absorber groove 414. The silicone ring 415 protrudes from the lower surface. When in use, the absorption and fixing integrated part 400 is placed on the skin surface, the indwelling tube passes through the lower through hole 413, the tube body is retained in the shell 410, and the tube head passes through the upper through hole 411 and is fixed in the tube head groove 412. The silicone ring 415 fits on the skin surface and is waterproof.

[0046] The surfaces of the left and right sides of the shell 410 are fixed with straps 430 , and the straps 430 fix the waterproof integrated part 400 on the arm.

[0047] In this embodiment, a cover body 420 is further included, and the periphery of the cover body 420 is a cover edge 421. The cover body 420 covers the housing 410, and the cover edge 421 is fixed on the side surface of the housing 410. After the cover body 420 is covered, the upper side of the housing 410 is sealed and has waterproof performance. At the same time, it can also protect the indwelling tube head.
