Description

Drainage tube fixing device

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a drainage tube fixing device.

Background

The drainage tube is used after a plurality of current clinical surgical operations, and has the main functions of helping seepage and the like in a wound surface or an abdominal cavity of a patient to smoothly flow out, and avoiding the seepage from accumulating in the wound surface or the abdominal cavity, otherwise, the condition of repeated attack of diseases or infection can be caused. At this moment, the guide pipe must be kept unobstructed, once blockage occurs, the pipe must be communicated in time, and if the pipe cannot be communicated, the pipe may need to be pulled out again, or even another guide pipe is inserted again. If the patient is advised to find that the honeycomb duct is abnormal, such as blockage or air leakage, medical staff must be informed in time, professional medical staff are allowed to handle, and the condition that the drainage tube is blocked and liquid flows out in a limited mode can be effectively avoided. Once the outflow of fluid is limited, it may lead to local infection or recurrent attacks of the disease.

The suture fixation method has the following disadvantages: 1. the suture line drags the tissue to cause pain of the patient, which is not beneficial to the exercise and the rehabilitation of the patient; 2. the suture is easy to cause tissue cutting, especially under the condition of needing long-term drainage, a new wound surface is formed to aggravate tissue trauma, and the tissue infection chance is increased; 3. the suture is dropped off after the tissue is cut off, so that the drainage tube is pulled out; 4. the suturing and fixing needs more instruments and is inconvenient to operate; 5. the depth of the drainage tube is inconvenient to adjust.

The adhesive tape fixing method has the following disadvantages: 1. easily cause anaphylactic reaction; 2. due to sweating, friction and other reasons, the adhesive plaster is not reliably fixed, and the drainage tube is easy to fall off; 3. meanwhile, the adhesive plaster is pasted on the skin of a patient, the fixation is not stable, the drainage tube has certain mobility, and bacteria in vitro are easily brought into the body to cause local and/or body cavity infection.

The drainage tube needs to be kept in place again after the tube is taken off accidentally, which not only increases the pain of the patient, but also increases the workload of medical staff and the medical cost. Properly fixing the drainage tube, improving the comfort of the patient and reducing the infection, which has important significance clinically.

2. Technical scheme

In order to solve the above problems, the present invention adopts the following technical solutions.

A drainage tube fixing device comprises a fixing disc and a fixing sleeve; one end of the fixed disc is positioned in the fixed sleeve, the end face of the other end of the fixed disc is attached to the end face of the fixed sleeve, and the fixed disc can rotate relative to the fixed sleeve; the fixed sleeve comprises a fixed step and a connecting sleeve; one end of the connecting sleeve is connected with the fixed step; at least two clamping grooves are arranged on the periphery of the connecting sleeve; one end of the fixed disc is provided with elastic clamping pieces matched with the clamping grooves in number; the elastic clamping piece is positioned in the clamping groove.

Preferably, a through hole is formed in the middle of the fixed disc; the inner diameter of the through hole is larger than that of the connecting sleeve and is coaxial.

Preferably, the end face of the fixed disc is provided with concave points.

Preferably, the end face of the fixed step is provided with a groove matched with the fixed disc, and the end face of the fixed disc is embedded into the groove.

Preferably, an accommodating cavity is formed in the connecting sleeve, and the elastic clamping piece is located in the accommodating cavity.

3. Advantageous effects

Compared with the prior art, the utility model has the beneficial effects that:

a drainage tube fixing device fixes a drainage tube on skin through a fixing device, effectively relieves pain caused to a patient on the skin through needle and thread sewing in the prior art, and effectively solves exercise and rehabilitation movement caused by the pain.

Secondly, convenient operation is simple, through rotatory fixed disk, after the elasticity fastener that will straighten rotated the position of draw-in groove, elasticity buckle is crooked under the condition that external force was eliminated, in the skin around the drainage tube was gone into to the card through elasticity buckle, fixes the drainage tube on skin.

And thirdly, the fixing device replaces the tape sticking mode in the prior art, and effectively prevents skin ulceration caused by allergy of partial people to the tape.

Detailed Description

As shown in fig. 1 to 6, a drainage tube fixing device includes a fixing plate 1 and a fixing sleeve 2. Wherein, 1 one end of fixed disk is located fixed sleeve 2, and the terminal surface and the 2 terminal surface laminating of fixed sleeve of the other end, moreover, fixed disk 1 relative fixed sleeve 2 can rotate. The fixed sleeve 2 comprises a fixed step 21 and a connecting sleeve 22, one end of the connecting sleeve 22 is connected with the fixed step 21, the outer diameter of the fixed step 21 is larger than that of the connecting sleeve 22, a groove 211 matched with the fixed disc 1 is formed in the end face of the fixed step 21, and the fixed disc 1 is embedded into the groove 211. An accommodating cavity 222 is arranged in the connecting sleeve 22, the lower end of the accommodating cavity 222 is closed, the upper end opening is positioned on the upper end surface of the groove 211, at least two clamping grooves 221 are arranged on the outer side of the circumference of the connecting sleeve 22, and the clamping grooves 221 are used for communicating the accommodating cavity 222 with the outside. The lower end face of the fixed disk 1 is provided with elastic clamping pieces 11, the number and the shape of the elastic clamping pieces 11 are matched with those of the clamping grooves 221, and the elastic clamping pieces 11 are positioned in the accommodating cavity 222.

Specifically, the middle part of the elastic clamping piece 11 is folded under the state of not receiving external force, the elastic clamping piece can be straightened under the action of external force, when the elastic clamping piece 11 is placed into the accommodating cavity 222 and does not coincide with the clamping groove 221, the elastic clamping piece 111 is straightened under the action of the inner wall of the accommodating cavity 222, when the elastic clamping piece 111 coincides with the clamping groove 221 by rotating the fixed disc 1, the blocking force of the inner wall of the accommodating cavity 222 disappears, the elastic clamping piece 111 recovers to the initial folded state, the convex part and the inner side of the skin where the fixing device is placed are extruded and fastened, and the fixing device is fixed on the surface layer of the skin.
