Description

Technical Field

[0001] This utility model relates to a catheter fixation component and belongs to the field of medical auxiliary equipment technology. Background Technology

[0002] A urinary catheter is a medical device used to drain urine. It is typically made of soft rubber, silicone, or plastic and is inserted into the bladder through the urethra to help patients urinate. It is commonly used for postoperative recovery, urinary dysfunction, coma, or prolonged bed rest. Types of urinary catheters include intermittent catheters and indwelling catheters. Aseptic technique must be observed during catheterization to prevent urinary tract infections.

[0003] Authorization announcement number (CN 219110558 U) discloses a urinary catheter fixation assembly, including a fixed base plate. A first restraint strap and a second restraint strap are fixedly installed on the left and right sides of the fixed base plate, respectively. A sliding groove is symmetrically opened on the rear surface of the fixed base plate. An installation groove is opened inside the fixed base plate. A light spring is fixedly installed on the front side of the installation groove. A limit block is fixedly installed at the end of the light spring away from the front side of the installation groove. A movable column is fixedly installed on the top of the limit block. A movable plate is provided on the rear side of the fixed base plate. A slider is fixedly installed on the left and right ends of the front side of the movable plate, respectively. A clamping mechanism is provided on the rear side of the movable plate. By setting a clamping mechanism in the urinary catheter fixation assembly, the purpose of fixing and clamping urinary catheters of different specifications is achieved, which brings convenience to nursing staff and ensures the work efficiency of nursing staff. However, in practice, most of the existing technologies only have simple fixation functions and lack the ability to manage excess catheter length. They can only fix a section of the catheter to the skin surface and cannot effectively store the excess part, which makes the catheter easy to be exposed, hanging or swinging when the patient moves. This not only increases the risk of the catheter being pulled or twisted, but also causes patient discomfort or catheter dislodgement.

[0004] Therefore, a catheter fixation component is proposed. Utility Model Content

[0005] In view of this, the present invention provides a catheter fixation assembly to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0006] The technical solution of this utility model is implemented as follows: a catheter fixing assembly includes a base plate, with support plates fixedly installed on all four sides of the top of the base plate, a top plate fixedly installed on the top of the support plates, and an adjustment assembly provided at the bottom of the top plate. The adjustment assembly includes a lead screw, a threaded sleeve, a first connecting block, a connecting rod, a second connecting block, a pin, a guide block, and a positioning roller. The lead screw is movably connected to the bottom of the top plate, and the lower end of the lead screw is movably connected to the top of the base plate through a rotating shaft. The threaded sleeve is threadedly connected to the surface of a knob. The first connecting block is fixedly connected to all four sides of the surface of the threaded sleeve. The guide blocks are located around all four sides of the surface of the base plate, and the positions of the four guide blocks correspond to those of the first connecting blocks. The positioning roller is movably connected to the bottom of the four guide blocks through a rotating shaft.

[0018] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] Example 1 like Figure 1-5As shown, this embodiment of the utility model provides a catheter fixing assembly, including a base plate 1. Support plates 2 are fixedly installed around the top perimeter of the base plate 1. A top plate 3 is fixedly installed on the top of the support plates 2. An adjusting assembly 4 is provided at the bottom of the top plate 3. The adjusting assembly 4 includes a lead screw 401, a threaded sleeve 403, a first connecting block 404, a connecting rod 405, a second connecting block 406, a pin 407, a guide block 408, and a positioning roller 409. The lead screw 401 is movably connected to the bottom of the top plate 3, and the lower end of the lead screw 401 is movably connected to the top of the base plate 1 via a rotating shaft. The threaded sleeve 403 is threadedly connected to the surface of a knob 402. The first connecting block 404 is fixedly connected to the perimeter of the surface of the threaded sleeve 403. Guide blocks 408 are located around the surface of substrate 1, and the positions of the four guide blocks 408 correspond to the positions of the first connecting blocks 404. The positioning roller 409 is movably connected to the bottom of the four guide blocks 408 via a rotating shaft. The second connecting block 406 is fixedly connected to the top of the four guide blocks 408. The connecting rod 405 is located inside the four first connecting blocks 404 and the second connecting blocks 406. The pin 407 is movably connected to the inside of the first connecting blocks 404 and the second connecting blocks 406. The connecting rod 405 is connected to the first connecting blocks 404 and the second connecting blocks 406 via the pin 407. A knob 402 is movably connected to the top of the top plate 3. The lower end of the knob 402 is fixedly connected to the upper end of the lead screw 401.

[0021] By adjusting the settings of component 4, the urinary catheter is wound onto the surface of the winding rod 5 and fixed by the inward movement of the positioning roller 409. This effectively accommodates excess urinary catheter, reduces the risk of catheter exposure, swinging, and being pulled, and improves patient comfort and safety.

[0022] Example 2 In one embodiment, a winding rod 5 is fixedly installed at the bottom and center of the substrate 1, a base plate 6 is fixedly installed at the lower end of the winding rod 5, and grooves 7 are provided around the top of the base plate 6. A connecting plate 410 is fixedly installed at the bottom of the positioning roller 409, and a slider 411 is fixedly installed at the lower end of the connecting plate 410. The slider 411 is slidably connected to the inner side of the groove 7. Guide grooves 412 are provided around the surface of the substrate 1, and guide blocks 408 are slidably connected to the inner side of the guide grooves 412.

[0023] By setting the slide groove 7, in cooperation with the connecting plate 410 and the slider 411, it can be ensured that the positioning roller 409 moves along the predetermined trajectory, and the positioning roller 409 is prevented from deviating during the movement. By setting the guide groove 412, it can play a guiding role and improve the stability of the guide block 408 during the movement.

[0024] In operation, this invention works as follows: after the catheter is wound onto the surface of the winding rod 5, the knob 402 can be manually rotated to drive the lead screw 401 to rotate. During the rotation of the lead screw 401, the threaded sleeve 403 will move upward through the threaded connection, thereby causing the first connecting block 404 to move upward along with the threaded sleeve 403. While the first connecting block 404 is moving, it will drive the upper end of the connecting rod 405 to move upward. Due to the oblique setting of the connecting rod 405, the lower end of the connecting rod 405 will move inward, thereby driving the second connecting block 406 and the guide block 408 to move inward. While the guide block 408 is moving, it will drive the positioning roller 409 to move inward, thus fixing the catheter.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
