Description

Technical Field

[0001] This utility model relates to the technical field of drainage tube instruments, and in particular to a fixing device and drainage system for drainage tubes. Background Technology

[0002] In thoracic surgery nursing, a drainage tube is typically connected to the patient's chest to drain pus, blood, and fluid accumulated between body tissues or in body cavities. This is a medical device used to prevent postoperative infection and promote wound healing. Many types of surgical drainage tubes are used clinically; some are used for urinary catheterization, others for wounds, and they are used in the thoracic cavity, brain cavity, gastrointestinal tract, and biliary tract, among others. The purpose of surgical drainage is to drain pus, blood, and fluid accumulated between body tissues or in body cavities to prevent postoperative infection and to avoid hindering wound healing.

[0003] After a drainage tube is inserted into a patient's chest cavity, a drainage tube fixation device is needed to secure it to the patient's chest. A common fixation device is adhesive tape. To use it, the tape is cut into an "E" shape, dividing one end into three sections. The middle section is wrapped around and adhered to the drainage tube, and the remaining two sections are adhered to the patient's skin, thus securing the drainage tube to the patient's body. This method of fixation is relatively ineffective, making the drainage tube prone to dislodgement during patient movement, or even accidental pull-out. Furthermore, when removing the tape, it needs to be detached, which can tear at the patient's wound, further aggravating pain. This method is quite inconvenient.

[0004] Currently, no effective solutions have been proposed for the problems of poor fixation, easy detachment, and inconvenience in tearing the tape in related technologies. Utility Model Content

[0161] In some of these embodiments, the third through-hole element 802 is a third through-hole.

[0162] The method of using this utility model is as follows:

[0163] (a) Preparation

[0164] The drainage device passes sequentially through the first through-hole element 102 through the adhesive element 101, through the second through-hole element 202 through the main body element 201, and through the third through-hole element 802 through the locking element 801;

[0165] Adhere the adhesive element 101 to the designated skin area.

[0166] (ii) Fixed Operations

[0167] Twist the locking element 801 clockwise to make it rotate circumferentially along the main body element 201 while moving downward along the axial direction of the main body element 201.

[0168] As the locking element 801 gradually descends to block the control element 501, the control element 501 is driven to move along the axis of the first sliding element 302 towards the support element 301 via the second sliding element 401.

[0169] The control element 501 drives the fixed element 701 to move accordingly through the second sliding element 401 until it abuts against the outer wall of the drainage device;

[0170] During the process, the elastic element 601 is compressed and deformed under the action of the control element 501.

[0171] (iii) Cancellation of fixed work

[0172] Twist the locking element 801 counterclockwise so that it rotates circumferentially along the main body element 201 while moving upward along the axial direction of the main body element 201.

[0173] As the locking element 801 gradually rises to separate the control element 501, the control element 501 is driven by the elastic element 601 to move away from the support element 301 along the axis of the first sliding element 302 via the second sliding element 401.

[0174] The control element 501 drives the fixed element 701 to move accordingly through the second sliding element 401 until it separates from the outer wall of the drainage device.

[0175] The advantages of this invention are that the drainage tube can be fixed by the cooperation of the main body unit, support unit, sliding unit, control unit, elastic unit, fixing unit and locking unit, which replaces the traditional tape fixing method, thereby improving the fixation stability; the locking unit can be used to control the drainage tube to separate it from the fixing unit by twisting the locking unit during disassembly, thereby removing the drainage tube and avoiding the tape tearing from the patient's wound during disassembly, reducing the patient's pain and providing convenience.

Generally, the outer diameter of the drainage device B is greater than the length and width of the fixing element 701, and the axial dimension of the drainage device B is greater than the height of the fixing element 701.
