Also, terms such as "first", "second", "third", etc. are used herein for the purpose of description and are not intended to indicate or imply importance or significance.

[0025] Referring to Figures 1 to 4 As shown, the sleeve drainage tube fixing device of the present invention comprises a sleeve tube body 1, both ends of the sleeve tube body 1 are restraint ends, after the drainage tube 2 enters the sleeve tube body 1, the sleeve tube body 1 is temporarily clamped on the drainage tube 2 through the restraint ends, playing a temporary fixing and protection role.

[0026] In the preferred embodiment, continuing to refer to the drawings, the fixing device further comprises a tightening cap 4 with an internal thread 3, the end of the sleeve tube body 1 comprises a deformed part and a connecting part connected in sequence in the axial direction, the deformed part is located at the outer end of the connecting part, the connecting part has an external thread 5, the tightening cap 4 is threadedly connected to the connecting part, and the tightening cap 4 and the connecting part are both conical frustums.

[0027] Specifically, the deformation part is composed of several circumferentially distributed and spaced valve pieces 6. After the drainage tube 2 is placed into the sleeve tube body 1, the valve pieces 6 wrap the outside of the drainage tube 2. The inner cavity of the tightening cap 4 is circular truncated cone-shaped, and the inner wall of the large end of the inner cavity is provided with an inner thread 3 matched with the outer thread 5. When the tightening cap 4 is screwed, the valve pieces 6 are tightened under the action of the tightening cap 4. The inner wall of the small end of the inner cavity of the tightening cap 4 tightens the valve pieces 6 to hold and fix the drainage tube 2, thereby realizing the fixation and protection of the connection between the inner and outer tubes of the placed drainage tube to the connection between the inner tube and the negative pressure device, reducing the probability of tube cavity distortion caused by changes in the patient's body position, the gravity of the drainage device, etc., effectively avoiding ineffective drainage and causing serious complications such as abdominal infection, and also protecting the exposed part of the inner tube of the drainage tube to avoid secondary infection caused by hospital infection.

[0028] In order to avoid the problem that the medical staff or family members may tighten the tightening cap 3 too much or too little when tightening, the end of the sleeve tube body 1 is provided with an axially distributed scale (not shown in the figure), and the range is preferably 0-20 cm. Through repeated tightening tests of the tightening cap 3, the maximum extrusion resistance value of the tightening cap 4 to the pressure resistance of the intraoperative catheter is determined, thereby determining the final tightening limit. In other words, when the medical staff or family members fix it, they only need to stop tightening the tightening cap 4 when they reach the specified scale, so the scale is the best fixed state of the tightening. This setting is convenient for the operation of medical staff and family members, and is simple and convenient to fix.

[0029] The side of the sleeve tube body 1 is provided with a first opening gap 7 which is axially distributed and penetrates the sleeve tube body 1 from the head to the tail. In the current use, the double-sleeve drainage tube is used, one end of which is in the human body, and the other end is connected to a negative pressure device. The side opening gap can remove the drainage tube in the sleeve tube body 1 at any time. Medical staff can pull the inner tube to flush the inner wall of the outer tube and the abdominal cavity, observe the drainage fluid, and the like. After the treatment is completed, the drainage tube in the opening gap continues to be used. In order to cooperate with the first opening gap 7, one side of the tightening cap 3 is provided with a second opening gap 8 which is axially distributed and penetrates the tightening cap 3 from the head to the tail. Through the second opening gap 8, the drainage tube 2 is conveniently installed and placed, which avoids the drainage tube 2 from being repeatedly disassembled and the head end of the drainage tube 2 from being inserted into the inner cavity hole of the tightening cap 4 during use. At the same time, in order to further realize the fixation of the sleeve tube body 1 by the tightening cap 4, the two opposite surfaces of the second opening gap 7 of the tightening cap 3 are respectively provided with a matched buckle 9. The two buckles 9 are fixed by buckling. During use, the buckles 9 of the second opening gap 8 of the tightening cap 4 are buckled with each other, so that the tightening cap 4 forms a stable body which can be fixed. Then, the inner thread 3 in the inner cavity of the tightening cap 4 is connected to the outer thread 5 at the head end of the sleeve tube body 1. In the process, in order to improve the stability of the tightening cap 4, a fixed sleeve or a magic tape can be further wound around the outer circle of the tightening cap 4 for secondary reinforcement, so as to reduce the problem that the buckle 9 on the tightening cap 4 is stretched apart during the screwing process. In the embodiment, the maximum tightening limit of the tightening cap 4 during screwing can be determined through multiple experiments, and the problem that the buckle 9 on the tightening cap 4 is stretched apart due to excessive force can also be avoided by cooperating with the set scale.

[0030] In addition, in order to facilitate the smooth effect of the tightening cap 4 during screwing, the transition is provided at the connection between the valve sheet 6 and the two ends of the sleeve tube body 1. In order to facilitate the operation of the medical staff and family members, the outer surface of the tightening cap 4 is also provided with anti-skid lines (not shown in the figure), which increases the friction force when contacted.

[0031] In the embodiment, the sleeve tube body 1 is made of PVC material and has certain toughness and elasticity, so as to improve the protection effect and reduce unnecessary bending during the process.

[0032] The sleeve tube body 1 can be axially stretched and contracted, which is convenient for corresponding elongation. Specifically, referring to FIG. 1, Figure 5 It can be seen that the sleeve tube body 1 includes an inner sleeve 10 and at least two axially distributed outer sleeves 11, preferably two outer sleeves 11 with the same axial length. The inner wall of the outer sleeve 11 and the outer wall of the inner sleeve 10 are connected by sliding through the sliding groove and the sliding block 12. It can be understood that the positions of the sliding groove and the sliding block 12 can be interchanged.

[0033] In use, the drainage tube part structure is put into through the opening on one side of the sleeve tube body 1, and then the sleeve tube body 1 is sleeved into the tightening cap 4, the sleeve tube body 1 is screwed and connected with the tightening cap 4 through the matched internal and external threads, and is moved to the specified scale, under the action of the tightening cap 4, the valve piece 6 at the end of the sleeve tube body 1 extrudes the put-in drainage tube 2, and with the continuous screwing of the tightening cap 4, the valve piece 6 is folded inward and is resisted by the drainage tube 2 more and more tightly, until the final tightening limit. In the process, the sleeve tube body 1 can be stretched to increase the length range of the drainage tube part to be protected, so as to protect the drainage tube part.

[0034] In the embodiment, in order to facilitate the drainage tube part to enter the sleeve tube body 1, the outer diameter of the drainage tube 2 is equal to the inner diameter of the sleeve tube body 1, and the radius of the small end of the inner cavity of the tightening cap 4 is smaller than the sum of the thickness of the valve piece 6 and the radius of the drainage tube 2, so that the clamping and fixing are facilitated.

[0035] The utility model discloses simple structure, convenient operation can be through the setting of tightening cap and valve piece to the drainage tube part of putting in is sustained tightening, thereby reach the purpose of fixed protection, reduced due to the patient body position change, the gravity effect of drainage device etc. cause the lumen distortion and fold, lead to the invalid drainage and cause the abdominal cavity infection such as serious complication, also protected the inside and outside pipe junction and the inner tube exposed part, avoided the hospital infection to the patient caused secondary infection.

[0036] The above is only the preferred embodiment of the utility model, and does not limit the implementation mode and protection scope of the utility model, and for those skilled in the art, it should be realized that the scheme obtained by equivalent replacement and obvious change of the utility model specification and drawing content should be included in the protection scope of the utility model.
