Description

A drainage tube fixing device Technical Field

[0001] This invention relates to the field of medical auxiliary products technology, and in particular to a drainage tube fixing device. Background Technology

[0002] Drainage tubes are widely used in clinical medicine to meet the drainage needs of various surgeries. They are mainly placed in human tissues or specific body cavities to drain blood, tissue fluid, secretions, and other fluids, preventing adverse symptoms such as compression and irritation of organs caused by accumulation in specific parts of the body. They also prevent postoperative infection and impair wound healing, and are even helpful for observing whether there is active bleeding at the surgical site or bleeding at the suture site after surgery. Furthermore, by examining the characteristics, quantity, and composition of various drainage fluids, the patient's postoperative recovery can be monitored. Technical issues

[0003] Please refer to Figures 1 to 3 for a prior art drainage tube fixing device, which includes: a patch 1 having a tube hole 2, a cutout 3 extending to the tube hole 2 on one side of the patch 1, and an adhesive layer 4 on the bottom surface of the patch 1; a fixing seat 5 disposed on the top surface of the patch 1 and closely attached to or close to the tube hole 2, the fixing seat 5 having a strap 6 and a strap hole 7 on the side facing the tube hole 2, the strap 6 having a plurality of anti-reverse teeth 8, and the strap hole 7 having a plurality of buckle teeth 9 that can engage and latch with the anti-reverse teeth 8.

[0004] In use, the drainage tube T1 is introduced into the tube hole 2 through the incision 3. The patch 1 is firmly adhered to the patient's skin using the adhesive layer 4. After the band 6 is wrapped around the drainage tube T1, it is passed through the band hole 7 of the fixation seat 5, so that the buckle teeth 9 in the band hole 7 and the anti-reverse teeth 8 of the band 6 engage and buckle with each other, so that the drainage tube T1 is bound and fixed towards the fixation seat 5 by the band 6.

[0005] However, the existing drainage tube fixing device has a problem where the fixing seat 5 is close to or near the tube hole 2, and the patch 1 and fixing seat 5 can obstruct the medical staff's view of the wound, which makes it difficult to disinfect and clean the wound.

[0006] In addition, the diameter of the tube hole 2 is small. Since the diameter of the drainage tube T1 varies, when encountering a large-diameter drainage tube T1, in addition to causing the drainage tube T1 to bend and deform, when the strap 6 binds and fixes the drainage tube T1 towards the fixing seat 5, it is also easy to cause the drainage tube T1 to be severely deformed or deviated, thereby affecting the drainage effect and wound healing. Technical solutions

[0007] To address the aforementioned issues, this invention provides a drainage tube fixing device capable of securing a drainage tube to the human body. The device includes: a fixing patch, which is annular in shape, having a first side and a second side arranged opposite to each other. The first side is provided with an adhesive layer, and the fixing patch is adhered to the human body through the adhesive layer. An opening is formed at the center of the fixing patch, and a slit is formed at the edge of the fixing patch, extending and communicating with the opening. The area of ​​the opening occupies at least one-quarter of the area of ​​the fixing patch. A fixing seat is disposed on the second side of the fixing patch, and the fixing seat is provided with a… The container includes a strap and a strap hole on the side of the fixing base facing the opening. The strap has multiple anti-reverse teeth arranged along its length. The strap hole has an elastic buckle. The elastic buckle has a locking tooth on the side facing the strap hole. The locking tooth can engage with each anti-reverse tooth to lock. The container also includes a control member that is slidably disposed in the container of the fixing patch. One side of the control member has a top abutment. The top abutment of the control member can abut against the drainage tube and wrap the strap around the drainage tube with one end extending into the strap hole. The drainage tube is then tied to the top abutment and the drainage tube is secured by the top abutment in conjunction with the strap.

[0008] In one embodiment, the control member has a connecting block and a control block connected to each other. The connecting block is slidably disposed in the receiving groove, and the top abutment is disposed on the side of the connecting block facing the opening direction. The control block is exposed in the receiving groove. When an external force pushes the control block, the connecting block can move forward or away from the opening direction, thereby causing the top abutment to move accordingly.

[0009] In one embodiment, the sides of the receiving groove are respectively provided with a plurality of teeth, and the control member is provided with two symmetrically arranged elastic abutments on the side opposite to the top abutment. The two elastic abutments can be engaged with the teeth to form a positioning. During the movement of the control member, the two elastic abutments can continuously bend inward and spring back outward. After the movement, the two elastic abutments are re-engaged with the teeth to form a positioning.

[0010] In one embodiment, the present invention further includes a positioning member slidably disposed between the contact block and the receiving groove of the control member. The positioning member can be controlled by external force to engage between two elastic locking portions, thereby restricting the bending deformation of the two elastic locking portions.

[0011] In one embodiment, the positioning member is provided with a positioning block, and the positioning member can move between a release position and a positioning position; when the positioning member is in the release position, the two elastic locking parts are not blocked by the positioning block and can bend and deform inward; when the positioning member moves to the positioning position, the positioning block is locked between the two elastic locking parts, restricting them from bending and deforming inward.

[0012] In one embodiment, the adhesive layer is covered with a peelable release paper.

[0013] In one embodiment, the release paper consists of two symmetrical semi-circular rings.

[0014] In one embodiment, the fixing patch is circular, and the opening is circular; the diameter of the opening is at least half the diameter of the fixing patch.

[0015] In one embodiment, the diameter of the opening is 20 mm to 80 mm.

[0016] In one embodiment, the top abutment is concave.

[0017] As described above, the drainage tube fixing device of the present invention has a large-area opening in the fixing patch, and the fixing seat does not block the opening. When the drainage tube is located in the opening, it can effectively avoid obstructing the wound through which the drainage tube is inserted, allowing medical staff to clearly observe the wound condition and facilitate wound disinfection and cleaning. In this way, it can improve the problem that the existing drainage tube fixing device will obstruct the medical staff's line of sight to observe the wound, and can also improve the problem that the diameter of the tube hole is too small, which can easily lead to the deformation of the drainage tube.

[0018] Furthermore, when using the drainage tube fixing device of the present invention, the top part of the control member is used to press against the drainage tube, and then the strap is used to wrap around the drainage tube to tighten it towards the top part. This can effectively prevent the drainage tube from deforming or shifting, ensuring that the drainage effect and wound healing are not affected. In this way, the problem of drainage tube deformation caused by the small tube hole in the prior art drainage tube fixing device can be improved.

[0019] Furthermore, the locking mechanism between the locking teeth and the two elastic locking parts of the present invention can effectively fix the position of the device, prevent displacement or loosening during use, and maintain the stability of the fixation; and when the control member moves, the two elastic locking parts will engage with the locking teeth, which can prevent the two elastic locking parts from being misaligned or improperly bent, and maintain normal operation; and through the elastic characteristics of the elastic locking parts, they can automatically return to the original locking position, ensuring quick and accurate positioning with a simple structure and operation.

[0020] In addition, the positioning element of the present invention can limit excessive bending of the elastic locking part, maintain the stability of the overall structure, thereby ensuring accurate operation and adjustment during use; moreover, the positioning element can serve as a key component for effective locking, preventing accidental movement or dislodging, ensuring the fixation effect of the drainage tube, thereby improving patient safety.

[0072] The following description, in conjunction with the drawings of a preferred embodiment of the present invention, is intended to enable those skilled in the art to implement the invention based on the statements herein.

[0073] Please refer to Figures 4 to 12. The present invention provides a drainage tube fixing device that can fix a drainage tube T2 to the human body (not shown in the figure).

[0074] The drainage tube fixing device of the present invention includes:

[0075] A fixing patch 10 is ring-shaped and has a first surface 11 and a second surface 12 arranged opposite to each other. The first surface 11 is provided with an adhesive layer 13, and a peelable release paper 14 is attached to the adhesive layer 13. The release paper 14 is used to protect the adhesiveness of the adhesive layer 13. When the release paper 14 is peeled off from the adhesive layer, the fixing patch 10 can be attached and fixed to the human body through the adhesive layer 13.

[0076] An opening 15 is formed through the center of the fixing patch 10, and a slit 16 is formed on the edge of the fixing patch 10. The slit 16 extends and connects to the opening 15, and the drainage tube T2 can be introduced into the opening 15 through the slit 16. The area of ​​the opening 15 occupies at least one-quarter of the area of ​​the fixing patch 10, and the diameter of the opening 15 is at least one-half of the diameter of the fixing patch 10. In this embodiment of the invention, the fixing patch 10 is circular, and the opening 15 is circular. The diameter of the opening 15 is 20 mm to 80 mm. The release paper 14 is composed of two symmetrical semi-circular rings, as shown in Figure 5.

[0077] A fixing seat 20 is disposed on the second surface 12 of the fixing patch 10. The fixing seat 20 does not obstruct the opening 15. The fixing seat 20 has a recessed groove 21 on the side opposite to the fixing patch 10. The two ends of the groove 21 are open. The two symmetrical sides of the groove 21 are respectively provided with a plurality of retaining teeth 211, as shown in Figures 4 and 5.

[0078] A strap 22 protrudes from the side of the fixing base 20 facing the opening 15, and a strap hole 23 is provided through the side of the fixing base 20 facing the opening 15. The strap 22 and the strap hole 23 are spaced apart. The strap 22 has a plurality of anti-reverse teeth 221 arranged along the length direction. One end of the strap hole 23 is provided with an elastic buckle 231. The side of the elastic buckle 231 facing the strap hole 23 has a buckle tooth 232, which can engage with each anti-reverse tooth 221 to buckle.

[0079] A control member 30 is slidably disposed in the receiving groove 21 of the fixed patch 10. The control member 30 can reciprocate in a direction parallel to the first surface 11 or the second surface 12 of the fixed patch 10. The control member 30 has a connecting block 31 and a control block 32 connected to each other. The connecting block 31 is slidably disposed in the receiving groove 21, and a top abutment 311 is provided on the side of the connecting block 31 facing the opening 15. The control block 32 is exposed in the receiving groove 21. When an external force pushes the control block 32, it can make the connecting block... 31 moves forward or away from the opening 15, thereby moving the top abutment 311 accordingly. The top abutment 311 of the control member 30 abuts against the drainage tube T2, and the strap 22 is wrapped around the drainage tube T2 with one end extending into the strap hole 23, binding the drainage tube T2 towards the top abutment 311. The top abutment 311 and the strap 22 are used to secure the drainage tube T2. In this embodiment of the invention, the top abutment 311 is concave arc-shaped to match the arc surface of the outer periphery of the drainage tube T2, as shown in Figures 8 to 12.

[0080] Additionally, the control member 30 has two symmetrically arranged elastic locking parts 33 on the side opposite to the top abutment 311. The two elastic locking parts 33 can be locked into the locking teeth 211 to form a positioning. During the movement of the control member 30, the two elastic locking parts 33 can continuously bend inward and spring back outward. After the movement, the two elastic locking parts 33 are re-locked into the locking teeth 211 to form a positioning.

[0081] In use, the release paper 14 is first peeled off, and then the drainage tube T2 is introduced into the opening 15 through the cut 16 (as shown in Figure 9). Next, the fixing patch 10 is firmly attached to the skin of the human body using the adhesive layer 13, ensuring that the fixing patch 10 is fixed around the drainage tube T2. Then, by pushing the control block 32 of the control member 30, the connecting block 31 of the control member 30 is driven to move towards the opening 15 until the top part 311 of the connecting block 31 abuts against the drainage tube T2 (as shown in Figure 10). Then, the strap 22 is wrapped around the drainage tube T2, and one end of the strap 22 is inserted into the strap hole 23 of the fixing base 20, so that the buckle 232 in the strap hole 23 and the anti-reverse tooth 221 of the strap 22 engage and lock with each other, forming a one-way limiting locking form, and the drainage tube T2 is bound and tightened towards the fixing base 20 by the strap 22, thus completing the fixation of the drainage tube T2 (as shown in Figure 11).

[0082] When removing the drainage tube fixing device, the elastic buckle 231 is pulled outward to separate the buckle teeth 232 of the elastic buckle 231 from the anti-reverse teeth 221 of the strap 22. Then, the strap 22 is pulled out from the strap hole 23 to release the binding around the drainage tube T2. Then, by pushing the control block 32 of the control member 30, the connecting block 31 of the control member 30 is driven to move backward away from the opening 15 until the top part 311 of the connecting block 31 separates from the drainage tube T2 (as shown in Figure 12). Finally, the fixing patch 10 is peeled off the skin of the human body to complete the entire removal process.

[0083] Please refer to Figures 13 to 17, which show another embodiment of the drainage tube fixing device of the present invention. The difference between this other embodiment and the above embodiment is that:

[0084] A positioning member 40 is slidably disposed between the connecting block 31 and the receiving groove 21 of the control member 30. The positioning member 40 can be controlled by external force to be engaged between two elastic locking parts 33, thereby restricting the bending and deformation of the two elastic locking parts 33.

[0085] Furthermore, the positioning member 40 is provided with a positioning block 41, and the positioning member 40 can move between a release position and a positioning position; wherein, when the positioning member 40 is in the release position, the two elastic locking parts 33 are not blocked by the positioning block 41 and can be bent and deformed inward; when the positioning member 40 moves to the positioning position, the positioning block 41 is locked between the two elastic locking parts 33, restricting them from bending and deforming inward.

[0086] When the control block 32 of the control member 30 is pushed, causing the connecting block 31 of the control member 30 to move forward toward the opening 15 or backward away from the opening 15, the positioning member 40 remains in the released position.

[0087] When the connecting block 31 of the control member 30 moves towards the opening 15, and the top part 311 abuts against the drainage tube T2, the positioning member 40 can be pushed to the positioning position, so that the positioning block 41 is locked between the two elastic locking parts 33, thereby restricting the two elastic locking parts 33 from bending and deforming inward, thus making the control member 30 stably positioned and preventing the control member 30 from sliding unexpectedly.

[0088] The following benefits can be obtained from the structure of the above specific embodiments:

[0089] 1. The drainage tube fixing device of the present invention has a large-area opening 15 on the fixing patch 10 and the fixing seat 20 does not block the opening 15. When the drainage tube T2 is located in the opening 15, it can effectively avoid blocking the wound through which the drainage tube T2 passes, so that medical staff can clearly observe the wound condition and facilitate the disinfection and cleaning of the wound.

[0090] 2. When using the drainage tube fixing device of the present invention, the top part 311 of the control member 30 is used to press against the drainage tube T2, and then the strap 22 is used to wrap around the drainage tube T2 to fasten the drainage tube T2 towards the top part 311. This can effectively prevent the drainage tube T2 from deforming or shifting, and ensure that the drainage effect and wound healing are not affected.

[0091] 3. The locking mechanism between the locking tooth 211 and the two elastic locking parts 33 of the present invention can effectively fix the position of the device, prevent displacement or loosening during use, and maintain the stability of the fixation; moreover, when the control member 30 moves, the two elastic locking parts 33 will engage with the locking tooth 211, which can prevent the two elastic locking parts 33 from being misaligned or improperly bent, and maintain normal operation of the control.

[0092] 4. The present invention can automatically return to the original buckle position through the elastic characteristics of the elastic locking part 33, so as to ensure quick and accurate positioning with simple structure and operation.

[0093] 5. The positioning member 40 of the present invention can limit the excessive bending of the elastic locking part 33, maintain the stability of the overall structure, thereby ensuring precise operation and adjustment during use.

[0094] 6. The positioning element 40 of the present invention can serve as a key component for effective locking, preventing accidental movement or dislodging, ensuring the fixation effect of the drainage tube T2, thereby improving patient safety.
