[0024] In order to explain the technical content and structural features of the utility model in detail, the following further description is made in combination with the embodiments and the accompanying drawings.

[0025] Referring to Figures 1 to 7 The utility model provides a kind of catheter joint protective sleeve 100 for fixing catheter joint, wherein, in the present application, catheter joint is specifically deep vein catheter infusion catheter joint, one end of catheter is located in the deep vein cavity of patient, the other end is located outside patient's body, and is connected with the liquid required to be input by catheter joint, and deep vein includes but is not limited to, such as femoral vein, subclavian vein, upper arm basilic vein and internal jugular vein. Overall, the catheter joint protective sleeve 100 of the utility model includes the hollow pipe 10 with elasticity and the positioning member 20 connected to the bottom wall or side wall of hollow pipe 10, and the pipe body 11 of hollow pipe 10 has notch 13 communicated with its pipe hole 12 or / and pipe body 11 has taper. Notch 13 is arranged along the longitudinal direction of pipe body 11, and the caliber of notch 13 is less than the aperture of pipe hole 12, so that the two opposite ends of pipe body 11 divided by notch 13 can be elastically deformed to form limiting portion 111. When catheter joint is placed in pipe hole 12 through notch 13, two limiting portions 111 on both sides of notch 13 cooperate to wrap or half wrap catheter joint. Positioning member 20 is strip-shaped, and is used to be detachably pasted on or detachably tied on patient.

[0026] Specifically, positioning member 20 is pasted on patient at the position close to catheter joint first, then catheter joint is placed in pipe hole 12 through notch 13, when entering pipe hole 12 from notch 13, two limiting portions 111 on both sides of notch 13 are extruded to both sides by catheter joint itself, or two limiting portions 111 are manually pulled away from each other, and the extrusion on two limiting portions 111 is released after catheter joint completely enters pipe hole 12, two limiting portions 111 reset, and cooperate to wrap or half wrap catheter joint.

[0027] Of course, the catheter connector can also be first placed in the tube hole 12 through the gap 13. When entering the tube hole 12 from the gap 13, the two limiting portions 111 on both sides of the gap 13 are pressed to both sides by the catheter connector itself, or the two limiting portions 111 are manually pulled away from each other. After the catheter connector is completely inserted into the tube hole 12, the pressing of the two limiting portions 111 is released, and the two limiting portions 111 are reset to wrap or semi-wrap the catheter connector. Then, the positioning member 20 is positioned and pasted on the patient, or the hollow tube 10 is connected to the patient's body through the positioning member 20. Among them, the hollow tube 10 can be directly connected to the patient's body through the positioning member 20, effectively adapting to the use of patients allergic to glue, and the positioning member 20 can also be wound around the hollow tube 10 and the patient's body for multiple turns before being connected, thereby enhancing the stability of the positioning of the catheter connector.

[0028] Specifically, the hollow tube 10 is a soft silica gel tube or a plastic tube, which is light and convenient as a whole, easy to store and use, and has high comfort. The hollow tube 10 is specifically a transparent tube or a colored tube. The transparent setting facilitates the medical staff to visually observe the fixing condition of the catheter connector and the liquid input condition, and the colored setting has rich colors, which makes the patient happy and beneficial to recovery. In addition, the tube body 11 has a taper, so the cross-sectional area of the hollow tube 10 gradually decreases from one end to the other end, thereby further enhancing the fixing of the catheter connector placed therein on the basis of the cooperation of the two limiting portions 111, especially when the catheter connector is inserted from the end with a relatively small area. It can achieve better positioning effect. It should be noted that in some embodiments, when the tube body 11 itself has a taper, the diameter of the gap 13 can be relatively small, and even the gap 13 can be omitted. The catheter connector is directly inserted into the hollow tube 10 from the relatively large end and is inserted out from the relatively small end. The taper of the hollow tube 10 itself can also achieve positioning. Among them, the hollow tube 10 and the positioning member 20 can be an integral structure, such as being integrally formed by a mold, or the hollow tube 10 and the positioning member 20 can be a split structure, such as the hollow tube 10 being detachably bonded to the positioning member 20, thereby being used as needed.

[0029] Referring to Figures 3 to 5 , the hollow tube 10 has various structures according to different shapes, thereby achieving the fixing of catheter connectors with different shapes. Among them, as shown in Figure 3 and Figure 4 , in the first structure and the second structure of the hollow tube 10, the shape of the cross section of the hollow tube 10 is approximately "C" shaped, and the difference lies in the size of the gap and the position of the gap. As shown in Figure 5 , in the third structure of the hollow tube 10, the shape of the cross section of the hollow tube 10 is polygonal. Of course, the shape of the cross section of the hollow tube 10 can also be "V" shaped, ring shaped, or "concave" shaped.

[0030] With reference to Figures 1 to 5 , according to the structure of the positioning member 20, the catheter joint protective sleeve 100 of the utility model has a first structure, in which structure, the positioning member 20 is detachably pasted on the patient. Specifically, the top side end of the positioning member 20 is connected with the bottom wall of the hollow tube 10, the bottom side end of the positioning member 20 is provided with an adhesive layer, and the adhesive layer is provided with a protective paper. In use, the protective paper is torn off, and the adhesive layer is exposed, thereby realizing pasting.

[0031] Among them, as Figure 1 indicated, the positioning member 20 is of an integral type structure, at this time, the area of the bonding surface of the positioning member 20 is relatively large, the positioning member 20 is bonded with the entire bottom wall of the hollow tube 20, thereby firmly bonding the entire hollow tube 20 on the body of the patient.

[0032] Of course, as Figure 2 indicated, the positioning member 20 is of a segmented type structure, the area of the bonding surface of each positioning member 20 is relatively small, and at least two positioning members 20 are spacedly bonded at different positions of the bottom wall of the hollow tube 10, on the basis of realizing firm bonding, reducing the area of the skin of the patient, reducing allergy, and improving the use comfort.

[0033] With reference to Figure 6 , the catheter joint protective sleeve 100 of the utility model has a second structure, in which structure, the positioning member 20 is detachably tied on the patient, effectively adapting to the use of patients allergic to glue, and further improving the adaptability. Specifically, one end of the positioning member 20 is connected with the side wall of the hollow tube 10, the other end of the positioning member 20 can be wound on the patient and the hollow tube 10 around the hollow tube 10, and is detachably fixed on itself through the bonding member arranged on itself. Among them, the bonding member is specifically a magic tape.

[0034] With reference to Figure 7 , in the third structure of the catheter joint protective sleeve 100 of the utility model, the difference between the second structure mainly lies in that the setting position and the number of the positioning member 10 on the side wall of the hollow tube 10 are different. In this structure, at least two positioning members 20 arranged in pairs are arranged on the side wall of the hollow tube 10 on both sides of the notch 13, each pair of positioning members 20 cooperates to be wound on the patient or the patient and the hollow tube 10, and is detachably tied between each other. Among them, the hollow tube 10 can be fixed on the patient by directly tying the two positioning members 20 arranged in pairs on the body of the patient, and the hollow tube 10 can also be fixed on the patient by winding each pair of positioning members 20 around the hollow tube 10 and the body of the patient for one or more turns before tying, further strengthening the stability of the positioning of the catheter joint.

[0035] Compared with the prior art, the catheter joint protective sleeve 100 comprises a hollow tube 10 with elasticity and a positioning member 20 connected to the bottom wall or the side wall of the hollow tube 10. On the one hand, the tube body 11 of the hollow tube 10 is provided with a notch 13 arranged along the longitudinal direction and communicated with the tube hole 12, and the notch 13 divides the tube body 11 into two limiting portions 111 capable of being elastically deformed at two opposite ends of the notch 12. The caliber of the notch 13 is smaller than the caliber of the tube hole 12, so that when the catheter joint is inserted into the tube hole 12 through the notch 13, the two limiting portions 111 on both sides of the notch are matched, which can be elastically deformed to move away from each other to facilitate the insertion of the catheter joint, and after the catheter joint is inserted into the tube hole 12, the two limiting portions 111 can move close to each other under the action of elastic restoring force to wrap or semi-wrap the catheter joint, thereby firmly fixing the catheter joint and preventing it from moving. The elastic setting of the hollow tube 10 also facilitates the fixation of catheter joints of different specifications, effectively improving the universality. The wrapping setting of the hollow tube 10 effectively reduces the weight, basically matches the catheter joint, effectively reduces the height protruding from the skin, avoids pulling the catheter joint, and thereby improves the safety of use. In addition, when the tube body 11 has a taper, the fixation of the catheter joint inserted into the tube body 11 is further strengthened by the shape of the tube body 11 based on the matching and positioning of the two limiting portions 111, especially when the catheter joint is inserted from the end with a relatively small area, a better positioning effect can be achieved. When the tube body 11 has a taper, the caliber of the notch 13 can also be relatively small, and even the notch 13 can be omitted. The catheter joint is directly inserted into the hollow tube 10 from the relatively large end and is inserted out from the end with a relatively small area, and the taper of the hollow tube 10 itself can also achieve positioning. On the other hand, the strip-shaped positioning member 20 can be detachably pasted or detachably tied to the patient, effectively improving the convenience of use, and only single-sided bonding avoids the adhesive pollution caused by multiple winding and pasting. The hollow tube 10 is tied to the patient's body by the positioning member 20, effectively adapting to the use of patients who are allergic to glue, further improving the adaptability, and the positioning member 20 can also be wound around the hollow tube 10 and the patient's body multiple times before being tied, further strengthening the stability of the positioning of the catheter joint. The catheter joint protective sleeve 100 has a simple overall structure, effectively avoids the direct contact of the adhesive tape with the catheter joint, only needs to insert the catheter joint into the hollow tube 10 with elasticity, is convenient to use, has firm positioning and high universality.

[0036] The above disclosure is only a preferred embodiment of the utility model, and cannot limit the scope of the utility model, so equivalent changes made according to the utility model claims all belong to the scope covered by the utility model.
