Description

Technical Field

[0001] The utility model relates to the technical field of fixing clamps, in particular to a fixing clamp for a medical catheter. Background Art

[0002] After a patient undergoes a surgical operation, it is usually necessary to insert a drainage tube on the patient's body surface to drain the patient's body fluids and infuse the patient, so as to facilitate the patient's postoperative recuperation. The drainage tube and the infusion tube need to be fixed and clamped by a fixing clip when in use to avoid the occurrence of dangerous situations due to the drainage tube or the infusion tube loosening or slipping.

[0003] However, when the current medical catheter fixing clamp fixes and clamps the catheter, the catheter is relatively soft and easily deformed, which may affect its passage, and the clamped catheter model is relatively single. In view of the above problems, a medical catheter fixing clamp is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a fixing clamp for a medical catheter to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fixing clamp for a medical catheter comprises a first clamp body and a second clamp body, wherein the first clamp body is rotatably connected to the second clamp body, a torsion spring is arranged between the first clamp body and the second clamp body at a rotating position, a suction cup is fixedly mounted on an outer wall of the first clamp body, and a clamping mechanism is arranged on an outer wall of the second clamp body;

[0007] The clamping mechanism includes a clamping plate, a connecting rod is fixedly connected to the bottom of one end of the clamping plate, a guide hole is opened on the outer wall of the second clamping plate, a guide sleeve is fixedly connected to the top thread of the inner wall of the guide hole, the connecting rod passes through the guide sleeve and is fixedly connected to a slider in the guide hole, the slider is slidably connected to the inner wall of the guide hole, and the connecting rod is slidably connected to the inner wall of the guide sleeve, a spring is sleeved on the connecting rod between the slider and the guide sleeve, and a screw is connected to the thread passing through the other end of the clamping plate.

[0008] As a further solution of the utility model: a storage cavity is provided at the tail end of the first clamp body and the second clamp body, and an extension arm is rotatably connected to the storage cavity via a pin shaft.

[0009] As a further solution of the utility model: a layer of rubber pad is fixedly connected to the inner wall of the first clamp and the second clamp.

[0010] As a further solution of the utility model: the top end of the screw rod is fixedly connected with a handle.

[0011] As a further solution of the utility model: a clamping hole is opened on the top of the second clamping body just below the screw rod, and the inner diameter of the clamping hole is matched with the diameter of the screw rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model pulls the clamping plate, and the clamping plate extends out of the guide sleeve with a fixedly connected connecting rod. The connecting rod is fixedly connected to the slider to squeeze the spring between the clamping plates and the second clamping body, and the clamping plate is loosened, the spring rebounds, and the connecting rod moves the clamping plate to clamp the catheter. The screw rod is rotated to adjust the extended length of the screw rod, so as to avoid deformation of the catheter clamped by the clamping plate, thereby avoiding deformation of the catheter affecting the passage, thereby meeting the clamping and fixing requirements for catheters of different models.

[0014] 2. The utility model fixes the clamping mechanism by pressing the first clamp and the second clamp, which squeeze the torsion spring. The torsion spring rebounds and clamps the first clamp and the second clamp on the rod or the bed. Similarly, by squeezing the suction cup, the device can be fixed on the head of the bed or the edge of the bed. Two ways of fixing the utility model are achieved, and the scope of use is increased.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3In an embodiment of the utility model, a fixing clamp for a medical catheter comprises a first clamp body 1 and a second clamp body 2, wherein the first clamp body 1 is rotatably connected to the second clamp body 2, a torsion spring 3 is arranged at a rotation point between the first clamp body 1 and the second clamp body 2, a suction cup 5 is fixedly installed on the outer wall of the first clamp body 1, and a clamping mechanism is arranged on the outer wall of the second clamp body 2;

[0021] The clamping mechanism includes a clamping plate 8, a connecting rod 12 is fixedly connected to the bottom of one end of the clamping plate 8, a guide hole 15 is opened on the outer wall of the second clamping body 2, and a guide sleeve 13 is fixedly connected to the top thread of the inner wall of the guide hole 15, the connecting rod 12 passes through the guide sleeve 13 and is fixedly connected to a slider 16 in the guide hole 15, the slider 16 is slidably connected to the inner wall of the guide hole 15, and the connecting rod 12 is slidably connected to the inner wall of the guide sleeve 13, and a spring 14 is sleeved between the slider 16 and the guide sleeve 13, and a screw 9 is threadedly connected to the other end of the clamping plate 8.

[0022] When in use, by pressing the first clamp body 1 and the second clamp body 2, the first clamp body 1 and the second clamp body 2 squeeze the torsion spring 3, and the torsion spring 3 rebounds to clamp the first clamp body 1 and the second clamp body 2 on the rod body or the bed body, so as to fix the clamping mechanism. Similarly, by squeezing the suction cup 5, the device can be fixed on the head of the bed or the edge of the bed. By pulling the splint 8, the catheter is built in between the splint 8 and the second clamp body 2. The splint 8 is loosened, and the spring 14 rebounds and moves with the splint 8 through the connecting rod 12 to clamp the catheter. By turning the screw 9, the length of the screw 9 is adjusted to avoid deformation of the catheter clamped by the splint 8.

[0023] A storage cavity 7 is provided at the tail end of the first clamp body 1 and the second clamp body 2, and an extension arm 6 is rotatably connected to the storage cavity 7 through a pin shaft. When in use, the extension arm 6 is rotated out from the storage cavity 7, and the extension arm 6 increases the length of the pressing end of the first clamp body 1 and the second clamp body 2. The first clamp body 1 and the second clamp body 2 are opened by pressing the extension arm 6, thereby reducing the pressing pressure.

[0024] A layer of rubber pad 4 is fixedly connected to the inner walls of the first clamp body 1 and the second clamp body 2. The first rubber pad 4 increases the friction between the first clamp body 1 and the second clamp body 2 and the clamping body, thereby increasing the stability of the clamping.

[0026] A clamping hole 10 is provided at the top of the second clamp body 2 just below the screw 9, and the inner diameter of the clamping hole 10 is adapted to the diameter of the screw 9. When the clamping plate 8 clamps and limits the catheter, the bottom end of the screw 9 is built into the clamping hole 10 to limit the screw 9, thereby limiting the position of the clamping plate 8.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
