Description

Technical Field

[0001] The present invention belongs to the technical field of medical fixation patches, and particularly relates to a drainage tube fixation patch for use after lumbar spine surgery. Background Art

[0002] Drainage is sometimes required after lumbar surgery. Drainage refers to a method of draining harmful fluids in the human body out of the body. Its basic principle is to place a drainage material into the body, and through adsorption, negative pressure, siphon and other effects, the body's fluids are drained out. When draining, the drainage hose needs to be fixed so that the drainage tube is safe, firm and does not slip off. This will use a fixation patch. The drainage tube fixation patch can isolate the wound surface from air exchange, effectively prevent secondary infection at the wound site, and also has an adsorption effect. It can adsorb exudates at any time, keep the wound surface clean and comfortable, and prevent wound ulceration.

[0003] Generally, for lumbar spine surgery on the posterior lumbar region, the wound is on the posterior lumbar region. After the surgery, the patient needs to lie flat and rest quietly. However, when lying flat, the wound on the posterior lumbar region is easily compressed, and when not lying flat, it is also easy to cause secondary damage to the lumbar spine. A fixation patch structure that can fit the posterior lumbar region and assist in lying flat is needed to improve comfort and convenience. Therefore, it is very necessary to provide a drainage tube fixation patch for use after lumbar spine surgery. Summary of the Invention

By adjusting the adjustment mechanism 13 to make the position of the clamping plate 14 match the drainage tube, the drainage tube passes through between the clamping plates 14. Start the motor 6, and the motor 6 drives the connecting needle 8 on the rotating rod 7 to rotate, causing the limiting rod 11 and the connecting rod 12 on the connecting needle 8 to pull and displace. With the help of the limitation of the slider 9 and the support beam 4, pull the clamping plate 14 driven by the adjustment mechanism 13 on the sliding plate 10 to move towards each other for clamping, achieving the fixation of the drainage tube. While assisting in lying flat, it improves comfort and convenience. The protection pad 15 increases the softness and protection degree of the surface of the clamping plate 14, which can protect the safety of the contact surface between the drainage tube and the clamping plate 14. Avoiding affecting the discharge due to excessive pressure squeezing the exudate inside the drainage tube, and at the same time, it can protect the safety of the drainage tube, avoiding damage and breakage of the drainage tube and the clamping plate 14 due to friction. After the drainage tube is fixed, one end passes through the outside of the pipe-passing hole 19 and is connected to the drainage bag to hold the exudate. When it is necessary to replace the drainage bag, remove the drainage bag, and block the end of the drainage tube with the plug cap 20 connected by the connecting rope 21, avoiding dirty sundries from entering the wound through the drainage tube and causing secondary infection. At the same time, it also avoids the exudate inside the drainage tube from flowing out and soiling the patient's clothes or bed sheets and quilts, improving cleanliness and health. The connecting rope 21 fixes the plug cap 20 to avoid loss of the plug cap 20. The power storage chamber 22 increases the storage space and can store and install the power storage block 23.

When the operation of passing the drainage tube through is required, the sliding door 26 is opened, and the operation is carried out through the outflow fixing port 3. Finally, the sliding door 26 can be pushed. With the help of the sliding groove 25, the pushing and pulling movement position of the sliding door 26 can be limited, the fixing port 3 can be closed, and the exposure of the internal components can be avoided to prevent damage, improving safety. The protective soft frame 27 can protect the safety of the four sides of the fixing port 3, avoid the damage of the drainage tube caused by the contact and friction between the four sides and the drainage tube, and can also protect the patient's skin from direct contact with the four sides of the fixing port 3 to prevent skin abrasion, improving safety.
