Description

TECHNICAL FIELD

[0001] The utility model relates to a catheter fixing device and belongs to the technical field of urological surgery auxiliary equipment. BACKGROUND

[0002] In the diagnosis and treatment process of urology, the rubber pipeline of the catheter is directly inserted into the bladder through the urethra, thereby assisting the patient's bladder to guide urination. During the use process, the catheter needs to be fixed in position to avoid the catheter deviating from the patient and causing treatment failure.

[0003] The existing catheter fixing device is directly fixed on the head of the bed or the patient's body by rubber band or rope. When the binding force is too large, the catheter is squeezed and deformed, affecting the normal outflow of subsequent liquid. When the binding force is too small, the catheter is easily displaced, the stability is poor, and the practicability of the device is reduced. Another part is directly pasted on the inner side of the patient's thigh by medical tape. The medical tape is easy to fall off, the fixing effect is poor, and when the patient turns over, the catheter is easily stretched and squeezed, directly leading to poor urination of the patient and possibly causing injury to the urethral part. Therefore, it is necessary to improve it. SUMMARY

[0004] The utility model aims at providing a catheter fixing device which is convenient to wear, has good fixing effect and is not easy to fall off, so as to solve the problems of the existing catheter fixing device that the binding force is too large to affect the normal outflow of subsequent liquid and the catheter is directly pasted on the inner side of the patient's thigh and is easily stretched and squeezed.

Specific implementation

[0023] As shown in the accompanying drawings Figures 1-6

[0024] The catheter fixing device is composed of fixed plate 1, elastic band 2, top cover 3, stretching unit and buckle 4, the left and right sides of fixed plate 1 are respectively provided with elastic band 2, and the two elastic bands 2 are bonded by magic tape 5, when using, the device is bound on the thigh of the patient by elastic band 2, and the tightness of elastic band 2 can be further adjusted by magic tape 5, and the device is very convenient to wear.

[0025] The fixed plate 1 is provided with stretching unit symmetrically, the stretching unit is composed of two stretching pieces, the two stretching pieces are arranged in staggered mode, the two stretching pieces form "S" shape, the stretching piece is composed of elastic sheet 6, first limit post 7, second limit post 8, fixed column 9 and buffer head 10, the elastic sheet 6 is in the shape of a hook, the one end of the elastic sheet 6 is in the shape of a ring, the fixed column 9 is fixedly installed on the fixed plate 1 corresponding to the ring-shaped end, the ring-shaped end of the elastic sheet 6 is matched with the fixed column 9, the first limit post 7 and the second limit post 8 are fixedly installed on the fixed plate 1 in staggered mode on the left and right sides of the elastic sheet 6 close to the fixed column 9, when using, the elastic sheet 6 can be limited by the fixed column 9, the first limit post 7 and the second limit post 8, the elastic sheet 6 is prevented from deviating, and the elastic deformation of the elastic sheet 6 can effectively ensure that the catheter 15 is buffered.

[0026] The other end of the elastic sheet 6 is fixedly installed with buffer head 10, the buffer head 10 is in the shape of a semicircular plate, the buffer head 10 is provided with limit slot 11 on the outside, the limit slot 11 can limit and guide the catheter 15, and the catheter 15 is prevented from slipping on the stretching unit.

[0027] The fixed plate 1 below the two stretching units is movably installed with guide slot wheel 12 through a short shaft, the guide slot wheel 12 has the following effects: first, the catheter 15 is assisted and supported, the span between the two stretching units is prevented from being too large, the catheter 15 is prevented from being bent at too small an angle and being easily blocked, and second, the catheter 15 is transitionally guided, and the installation of the catheter 15 in the stretching unit is more stable.

[0028] ​One of the fixed plate 1 on the side of the stretching unit is fixedly installed with a buckle 4, the cross section of the buckle 4 is "C" shape, and the buckle 4 can form clamping and limiting on one end of the catheter 15 during use, thereby facilitating the disassembly and assembly of the catheter 15.

[0029] The top cover 3 is arranged outside the stretching unit, and the top cover 3 is matched and clamped with the fixed plate 1. The cross sections of the fixed plate 1 and the top cover 3 are circular respectively, which is beneficial to protect the skin of the patient's thigh from being scratched. The diameters of the fixed plate 1 and the top cover 3 are consistent, and a plurality of clamping holes 13 are uniformly arranged at the edges of the fixed plate 1. A plurality of clamping columns 14 are arranged on the top cover 3 corresponding to the clamping holes 13. The clamping column 14 is a variable-diameter column, and the small-diameter end of the clamping column 14 is matched and clamped with the clamping hole 13. During use, the variable-diameter clamping column 14 makes the top cover 3 and the fixed plate 1 have a gap, which is convenient for installing the stretching unit and the buckle 4, and also protects the catheter 15 from being squeezed.

[0030] During use of the catheter fixing device, first, the device is bound on the patient's thigh (applicable to the left leg or the right leg) through the cooperation of the elastic band 2 and the magic tape 5, then the catheter 15 on the patient's body is wound in an "S" shape along the buffer head 10 of one side of the stretching unit, and after passing through the guide groove wheel 12, it is wound out in an "S" shape along the buffer head 10 of the other side of the stretching unit, and finally one end of the catheter 15 is clamped on the buckle 4, and the top cover 3 is matched and clamped on the fixed plate 1 through the cooperation of the clamping column 14 and the clamping hole 13, thereby completing the fixing work of the catheter 15.

The cooperation of the multiple stretching units makes the catheter 15 have a buffer stroke when it is wound on the stretching unit, thereby effectively avoiding the overstretching of the catheter 15 when the patient turns over or moves the catheter 15, effectively protecting the catheter 15 from being pulled out excessively, and facilitating the arrangement and storage of the catheter 15 in an "S" shape without affecting the normal urination of the patient. The use is very convenient.

[0031] The catheter fixing device can limit and fix one end of the catheter 15 through the buckle 4, which is very convenient for disassembly and assembly of the catheter 15. The catheter fixing device is convenient to wear, has good fixing effect and is not easy to fall off, solves the problems that the existing catheter fixing device has too much binding force to affect the normal flow of subsequent liquid and the catheter 15 is directly pasted on the inner side of the patient's thigh and is easy to be stretched and squeezed excessively, and is very suitable for fixing the catheter 15 of a urinary patient.
