Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a drainage tube fixing device. Background Art

[0002] A drainage tube is a medical device used for clinical surgical drainage. It guides pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. When using a drainage tube, some fixing devices are needed to fix the drainage tube to prevent it from falling off.

[0003] A drainage tube fixing device currently in use has been found through searching, for example, in a Chinese patent document with authorization publication number CN219071736U, which discloses a drainage tube fixing device, including a drainage tube support plate, a fixing belt is installed at the left end of the drainage tube support plate, and a support rod is installed on the upper surface of the drainage tube support plate. The utility model is provided with a fastening component. After the medical staff puts the fixing belt on the outside of the limb part of the drainage patient, the motor is turned on to drive the rotating rod to rotate through the first gear and the second gear to store the fixing belt. The device can be firmly fixed on the patient, thereby effectively avoiding displacement and pulling of the drainage tube. The air flow exchange can be carried out on the skin of the area through the ventilation hose to avoid the skin of the area being stuffy and sweating profusely.

[0004] Although the above patents solve the problems in the above-mentioned background technology, they still have the following shortcomings: 1. The drainage tube fixing plate in the device relies on a fixing bolt to achieve fixation, and this fixing method is not adjustable. Therefore, when fixing drainage tubes of different sizes, it is easy for the drainage tube fixing plate to fail to form a stable contact with the drainage tube, which in turn causes the drainage tube to slide and shift, which is not conducive to the effective guidance of pus, blood, and liquid, and reduces the applicability of the device; 2. The drainage fixing plate in the device is easy to detach from the drainage tube when the position is adjusted in the drainage tube. Therefore, when using it, it is easy to cause trouble to the user and is not conducive to subsequent use.

[0005] In summary, the utility model solves the problems in the above-mentioned background technology by designing a drainage tube fixing device. Utility Model Content

[0027] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0028] A drainage tube fixing device comprises a drainage tube 1 and a sleeve 2 sleeved on the outside of the drainage tube 1, wherein a clamping block 201, a limiting column 202 and a supporting compression spring 203 are respectively arranged inside the sleeve 2, a supporting seat 3 is fixedly installed at the bottom of the sleeve 2, and an adhesive patch 4 is arranged at the bottom of the supporting seat 3;

[0029] Specifically, the sleeve 2 is a semi-cylindrical structure with an open top, and has two clamping blocks 201. The two clamping blocks 201 are arranged in a front-to-back mirror image with respect to the inner wall of the sleeve 2, and the opposite side surfaces thereof are respectively fixed to the limiting column 202 and the opposite ends of the supporting compression spring 203, one end of the supporting compression spring 203 is in contact with the inner wall of the sleeve 2, and one end of the limiting column 202 is fitted through the inner wall of the sleeve 2 and extends outward;

[0030] In this embodiment, the fitting contact between the limiting column 202 and the inner wall of the sleeve 2 is mainly used to limit the displacement of the clamping block 201, and the setting of the supporting compression spring 203 is mainly used to elastically support the clamping block 201, so that the clamping blocks 201 can move toward each other smoothly, thereby forming a sliding clamp between the clamping block 201 and the outer surface of the drainage tube 1, which is convenient for the subsequent fixation of the drainage tube 1 in different positions.

[0031] Specifically, the bottom surface of the adhesive patch 4 is an adhesive surface and is pasted with release paper;

[0032] In this embodiment, the adhesive patch 4 is mainly used to form adhesion with the patient's skin surface, thereby achieving the function of fixing the support base 3 and the sleeve 2.

[0033] In this embodiment, please refer to Figure 1 and Figure 2 The left and right ends of the support seat 3 are respectively fixedly mounted with arc rings 5, the top of the arc ring 5 is provided with a rubber layer 6, and the bottom of the arc ring 5 is fixedly mounted with a foam sticker 7;

[0034] Specifically, the arc ring 5 is symmetrically distributed about the outer surface of the support seat 3, the vertical cross-section of the rubber layer 6 is a semi-arc structure, and adhesive strips 701 are provided at both the front and rear ends of the top of the foam sticker 7;

[0035] In this embodiment, the arc ring 5 is mainly used to support the rubber layer 6, and the rubber layer 6 is mainly used to contact the drainage tube 1, and the adhesive strip 701 is mainly used to drive the foam patch 7 to form a wrapping contact with the drainage tube 1, thereby achieving the effect of firmly fixing the drainage tube 1 and meeting the fixing requirement of the drainage tube 1.

[0036] The working process of the utility model is as follows: when using a drainage tube fixing device, the sleeve 2 is first moved and the sleeve 2 is pressed into the clamping block 201. Under the extension of the support compression spring 203, the support compression spring 203 drives the clamping block 201 to move toward each other, and the clamping block 201 drives the limit column 202 to slide with the inner wall of the sleeve 2 and form contact with the outer surface of the drainage tube 1, thereby realizing the sleeve installation operation of the support seat 3, and then the support seat 3 is slid along the outer side of the drainage tube 1 to the limb part of the patient that needs drainage. Then the release paper is torn off to expose the adhesive surface of the adhesive patch 4 and contact the patient's skin surface, so that the support seat 3 and the sleeve 2 are fixed, and finally the foam patch 7 is moved to wrap the outer surface of the drainage tube 1. Under the action of the adhesive strip 701, the foam patch 7 and the drainage tube 1 remain relatively still. At this time, the rubber layer 6 is in friction contact with the drainage tube 1, so that the drainage tube 1 is firmly fixed, avoiding the drainage tube 1 from sliding and shifting during operation, improving the fixing effect of the device, and facilitating subsequent use.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
