Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a novel auxiliary device for puncture of medium-length catheters. Background Technology

[0002] In modern medical practice, medium-length catheter puncture is widely used in various clinical treatments, such as intravenous infusion and drug injection. However, traditional puncture procedures face many challenges. During the puncture, the attending physician often needs an assistant to lift the patient's arm to find a suitable puncture angle, but this method is affected by many factors and can easily lead to inaccurate puncture points.

[0003] Currently, precise adjustment of the puncture angle for medium-length catheters remains a major challenge for medical professionals. Clinically, when stabilizing the patient's forearm with manual support and then searching for the appropriate puncture angle, puncture errors are prone to occur because manual support cannot stably stabilize the patient's arm. If the patient accidentally shakes their arm during the puncture, or if the assistant supporting the patient's arm trembles after holding it up for a long time, the accuracy of the puncture will be affected.

[0004] In view of the above situation, this utility model is hereby proposed! Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a novel auxiliary device for medium-length catheter puncture.

[0013] Optionally, the pressure adjustment knob has a hexagonal groove at its end that matches the hexagonal block, and the knob surface has anti-slip texture.

[0014] In summary, this application includes the following beneficial technical effects: This invention utilizes a wide-face restraint band, a limiting roller, a flexible toothed rack, and toothed blocks to flexibly adjust the tightness of the restraint according to the actual condition of the patient's wrist, stabilizing and fixing the patient's wrist and preventing wrist movement from affecting the puncture operation during the procedure, thus improving the success rate and safety of the puncture.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0018] This application discloses a novel auxiliary device for puncturing medium-length catheters.

The base plate 301 is fixedly installed on one side of the angle adjustment assembly 2. The wrist support plate 302 is fixedly connected to the top of the base plate 301. The support plate connecting column 303 is built into the wrist support plate 302. The restraint strap base 304 is fixed to one side of the top of the base plate 301. One end of the wide restraint strap 305 is connected to the restraint strap base 304, and the other end movably passes through the limiting roller 306 and is fixedly connected to the flexible rack 307. The toothed block 308 is fixedly set on the side of the base plate 301 away from the limiting roller 306 and forms an meshing connection with the flexible rack 307.

[0021] The restraint assembly 3 also includes a pressure plate 309, a bolt 310 and an internal threaded hole 311. The pressure plate 309 is movably installed on one side of the toothed block 308. The bolt 310 passes through the pressure plate 309 and the toothed block 308 in sequence and is threadedly connected to the internal threaded hole 311. The internal threaded hole 311 is opened on the side of the base plate 301 away from the limiting roller 306.

[0022] Angle adjustment assembly 2 includes a first adjustment assembly 21, a second adjustment assembly 22, and a third adjustment assembly 23, which are hinged sequentially by a bracket. Each adjustment assembly includes a lower hinge block 201, an internal hexagonal groove 202, a hexagonal block 203, a first damping ring 204, an internal groove locking block 205, an external convex locking block 206, a second damping ring 207, an upper hinge block 208, and a pressure adjustment knob 209. The lower hinge block 201 is fixed to the top of the bracket, and its side wall has an internal hexagonal groove. The groove 202 is fixedly installed with the hexagonal block 203. The first damping ring 204 is fixed to the side of the lower hinge block 201 away from the hexagonal block 203. The inner groove block 205 with a thickness reduced by 2mm is embedded inside. The outer protruding block 206 engages with the inner groove block 205 and is embedded in the second damping ring 207. The second damping ring 207 is fixedly connected to the upper hinge block 208. The pressure adjustment knob 209 is movably installed on the upper hinge block 208 and is connected to the hexagonal block 203 by threads.

[0023] The wrist support plate 302 is composed of multiple independent silicone support plates arranged at 5mm intervals, and each silicone support plate is connected and fixed in series through the support plate series column 303.

[0024] The supports of the first adjustment component 21, the second adjustment component 22 and the third adjustment component 23 are connected by a two-way hinge structure, and the hinge axes of each support are orthogonally distributed.

[0025] The first damping ring 204 and the second damping ring 207 are made of elastic damping material, and the meshing surfaces of the inner groove block 205 and the outer convex block 206 are provided with progressive meshing teeth.

[0026] The pressure adjustment knob 209 has a hexagonal slot at its end that matches the hexagonal block 203, and the knob surface has anti-slip texture.

[0027] Further explanation is needed: The angle adjustment assembly 2 plays a crucial role in the entire auxiliary device. It comprises a first adjustment assembly 21, a second adjustment assembly 22, and a third adjustment assembly 23, which are sequentially hinged together by brackets. The brackets employ a bidirectional hinge structure, with the hinge axes of each bracket orthogonally distributed. This unique design allows the entire assembly to be flexibly adjusted in multiple dimensions. The lower hinge block 201 is fixed to the top of the bracket, serving as a basic connecting component. Its internal hexagonal slot 202 facilitates installation and adjustment operations. The hexagonal block 203 is threaded onto the pressure adjustment knob 209. The connection allows for adjustment of the pressure on the first damping ring 204 and the second damping ring 207 by rotating the pressure adjustment knob 209. The first damping ring 204 and the second damping ring 207 are made of elastic damping material, and the meshing surfaces of the inner groove block 205 and the outer convex block 206 are provided with progressive meshing teeth. This not only makes the adjustment process smoother, but also ensures that the adjusted angle is kept stable. The angle adjustment component 2 can accurately adjust the puncture angle to adapt to different patient positions and blood vessel locations, greatly improving the accuracy and success rate of puncture.

[0028] The main function of the restraint assembly 3 is to stabilize the patient's wrist and ensure a smooth puncture procedure. The base plate 301 is fixed to one side of the angle adjustment assembly 2, providing the mounting base for the entire restraint assembly 3. The wrist support plate 302 is composed of multiple independent silicone support plates arranged at 5mm intervals, connected and fixed in series by support plate connecting columns 303. The soft silicone material conforms to the wrist, effectively improving patient comfort while ensuring the structural stability of the support plate. The restraint strap base 304 is fixed to one side of the top of the base plate 301, and one end of the wide restraint strap 305 is connected to it, with the other end movable through... The limiting roller 306 is fixedly connected to the flexible rack 307. Through the limiting and guiding function of the limiting roller 306, the wide-face restraint band 305 can remain stable during adjustment. The flexible rack 307 is engaged with the toothed block 308 fixed on the other side of the base plate 301, which can flexibly adjust the length of the restraint band to achieve a stable restraint on the patient's wrist. In addition, the design of the pressure plate 309, bolt 310 and internal threaded hole 311 further strengthens the fixation of the engagement position of the flexible rack 307 and the toothed block 308, prevents the restraint band from loosening, and provides reliable wrist fixation for puncture.

[0029] The implementation principle of a novel auxiliary device for medium-length catheter puncture in this application is as follows: First, the clamping base 1 is placed firmly on a suitable support surface to provide a stable foundation for the entire device. Then, based on the patient's approximate body position and possible puncture site, the angle adjustment component 2 is initially adjusted. By operating the hinge structure between the first adjustment component 21, the second adjustment component 22, and the third adjustment component 23, the required orientation for puncture is roughly determined. The lower hinge block 201, the upper hinge block 208 in each component, and the bidirectional hinge structure between the support, together with the orthogonally distributed hinge axes, allow the angle adjustment component 2 to rotate flexibly in multiple dimensions to adapt to different patient body postures.

[0030] Next, guide the patient to place their wrist on the wrist support plate 302 of the restraint assembly 3. The wrist support plate 302 is composed of multiple independent silicone support plates arranged at 5mm intervals, which are connected and fixed in series by the support plate connecting column 303. The soft silicone material fits the wrist and provides comfortable support for the patient. At this time, pull the wide restraint strap 305 out from the restraint strap base 304, so that it wraps around the patient's wrist and passes through the limiting roller 306. The limiting roller 306 plays a limiting and guiding role to ensure that the wide restraint strap 305 maintains a stable direction during subsequent adjustment.

[0031] Next, depending on the thickness of the patient's wrist, the wide restraint strap 305 is pulled, causing it to move the flexible rack 307 fixedly connected to it. The flexible rack 307 engages with the toothed block 308 fixed on the other side of the base plate 301. In this way, the length of the restraint strap can be flexibly adjusted to achieve initial fixation of the patient's wrist. After adjusting to a suitable tightness, the fixation is further strengthened using the pressure plate 309, bolt 310, and internal threaded hole 311. The pressure plate 309 is placed on one side of the toothed block 308, and the bolt 310 is threaded through the pressure plate 309 and the toothed block 308 in sequence and then threaded into the internal threaded hole 311. The bolt 310 is tightened to ensure that the engagement position of the flexible rack 307 and the toothed block 308 is firm, preventing the restraint strap from loosening, thereby stabilizing and fixing the patient's wrist and providing reliable protection for the puncture process.

[0032] Next, after the patient's wrist is stabilized, if further precise adjustment of the puncture angle is required, the angle adjustment component 2 is operated again. By rotating the pressure adjustment knob 209, the pressure on the first damping ring 204 and the second damping ring 207 is changed. The first damping ring 204 and the second damping ring 207 are made of elastic damping material. The meshing surfaces of the inner groove block 205 and the outer convex block 206 are provided with progressive meshing teeth. As the pressure adjustment knob 209 is rotated, the meshing state between the inner groove block 205 and the outer convex block 206 changes, thereby finely adjusting the relative angle between each adjustment component. This fine adjustment can accurately adjust the puncture angle to adapt to the blood vessel position of different patients, greatly improving the accuracy of puncture.

[0033] Finally, after completing all the above preparations and adjustments, medical staff can perform a medium-length catheter puncture. At this time, the device has stabilized and fixed the patient's wrist, and the puncture angle has been precisely adjusted, providing stable and suitable operating conditions for the puncture, which helps to improve the success rate and safety of the puncture and ensures that the puncture process is carried out smoothly.
