Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and in particular to a 3D printing catheter clamping device based on asymmetric split and ball-hole mortise and tenon joints. Background Art
[0002] A medical catheter holder is a device used in the medical field. It is mainly used to fix and support various types of medical catheters to ensure the safety, stability and normal use of the catheters. It prevents the catheters from falling off, shifting or accidentally being pulled out during use. When the patient turns over, moves or receives nursing operations, it can keep the catheter in the correct position to ensure the continuity and effectiveness of treatment.
[0003] Although most current catheter clamping devices are capable of clamping the catheter, during use, due to their often symmetrical splitting, the clamping pressure is concentrated on the connection interface. This can easily lead to the device breaking apart over long periods of use, resulting in a failure in clamping the catheter, which is very inconvenient for medical staff to use.
[0004] Therefore, the present invention provides a 3D printed catheter clamping device based on asymmetric split and ball-hole mortise and tenon to solve the above problems. Utility Model Content
[0005] (1) Technical problems solved
[0006] The utility model provides a 3D printing catheter clamping device based on asymmetric split and ball-hole mortise and tenon, aiming to solve the problems raised in the background technology.
[0007] (2) Technical solution
[0008] To achieve the above objectives, the present invention provides the following technical solutions:
[0009] The 3D printed catheter clamping device based on asymmetric split and ball-hole mortise and tenon joints includes a main clamping body and a secondary clamping body, wherein the outer wall of the main clamping body is provided with a guide hole;
[0010] A snap-in ball hole is provided on the upper top of the main clamp body, and the outer surface of the auxiliary clamp body is snap-connected to the snap-in ball hole on the upper top of the main clamp body through a snap ball. There are multiple snap-in ball holes and multiple snap balls.
[0011] As a preferred technical solution of the present application, an extrusion strip is fixedly connected to the inner wall of the main clamp, and the extrusion strip is symmetrically arranged along the center of the main clamp.
[0012] As a preferred technical solution of the present application, an anti-slip strip is fixedly connected to the inner wall of the auxiliary clamping body, and the anti-slip strip is symmetrically arranged along the center of the auxiliary clamping body.
[0013] As a preferred technical solution of the present application, a pipe outlet is provided on the outer wall of the main clamp body, and the pipe outlet is located on one side of one of the clamping ball holes.
[0014] As a preferred technical solution of the present application, outer walls of the main clamp and the auxiliary clamp are coated with a waterproof and antibacterial layer.
[0015] (3) Beneficial effects
[0016] By setting up the main clamp body and the auxiliary clamp body, the clamping stability of the catheter can be improved through the cooperation of various components, ensuring the safety of the catheter during use by the operator. The one-piece main clamp body can be used to accurately match the clamping ball hole opened therein with the clamping ball fixedly connected to the auxiliary clamp body, which can not only improve the clamping speed, but also ensure the clamping stability and realize three-point self-locking. At the same time, through the material properties of the main clamp body itself, radial contraction force can also be applied to the catheter, further improving the stability of the catheter in use.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] The utility model provides a 3D printing catheter clamping device based on asymmetric split and ball hole tenon, such as Figure 1-Figure 3 As shown, the 3D printed catheter clamping device based on asymmetric split and ball-hole mortise and tenon comprises a main clamping body 1 and an auxiliary clamping body 2. The outer wall of the main clamping body 1 is provided with a guide hole 3;
[0024] A snap-in ball hole 4 is provided at the top of the main clamp body 1 , and the outer surface of the auxiliary clamp body 2 is snap-fitted to the snap-in ball hole 4 at the top of the main clamp body 1 via snap-in balls 5 . There are multiple snap-in ball holes 4 and snap-in balls 5 .
[0025] An extrusion strip 6 is fixedly connected to the inner wall of the main clamping body 1 , and the extrusion strip 6 is symmetrically arranged along the center of the main clamping body 1 .
[0026] The inner wall of the auxiliary clamping body 2 is fixedly connected with an anti-slip strip 7 , and the anti-slip strip 7 is symmetrically arranged along the center of the auxiliary clamping body 2 .
[0027] Specifically, the integrally formed main clamp body 1 and auxiliary clamp body 2 can ensure the stability of the catheter during use. At the same time, since the two are asymmetrically split, they can be easily replaced by the operator, avoiding the situation where the catheter needs to be replaced together during the traditional replacement process. It can not only improve the operator's operational flexibility, but also save the use cost to a certain extent. During use, the multiple clamping balls 5 provided on the auxiliary clamp body 2 and the clamping ball holes 4 opened on the main clamp body 1 can quickly and stably and accurately clamp the two together to ensure the use stability of the catheter therein. At the same time, the clamping of multiple clamping balls 5 can achieve three-point self-locking, ensuring that the catheter will not loosen during use. The guide hole 3 can facilitate the insertion of the catheter into it, thereby improving operational efficiency. The extrusion strip 6 on the inner wall of the main clamp body 1 and the anti-slip strip 7 on the inner wall of the auxiliary clamp body 2 can avoid the phenomenon of the catheter falling off due to pulling operation when the catheter is in use, thereby further improving the operator's use stability.
[0028] The outer wall of the main clamp body 1 is provided with a pipe outlet 8 , which is located on one side of one of the clamping ball holes 4 .
[0029] The outer walls of the main clamping body 1 and the auxiliary clamping body 2 are both coated with a waterproof and antibacterial layer.
[0030] Specifically, the pipe outlet 8 opened on the outer wall of the main clamp 1 can facilitate the positioning of the pipeline and improve its stability in use. The waterproof and antibacterial layer coated on the outer walls of the main clamp 1 and the auxiliary clamp 2 can prevent the clamp from being contaminated during use, thereby improving the safety and stability of the catheter clamping device.
[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
