Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to a urinary catheter fixing device. Background Art

[0002] After male patients undergo similar surgeries such as prostatectomy and radical prostatectomy, a urinary catheter is usually inserted into the bladder to drain urine. The drainage time is determined according to the different symptoms of the patients, ranging from 1 to 3 days at the shortest, and up to 1 to 2 weeks or even longer. Once the urinary catheter is inserted into the patient's bladder, it should be fully ensured that it always remains in the same position until it is removed. Otherwise, once the position changes, the drainage effect will be affected or even fail, and it must be reset by medical staff.

[0003] To fix the urinary catheter, the traditional method is to use adhesive tape to fix the part of the urinary catheter outside the body on the patient's body, such as on the patient's thigh. Although this fixing method of the urinary catheter can prevent the urinary catheter from moving for a certain period of time, thus effectively avoiding the urinary catheter from slipping out of the bladder, however, the adhesive tape will be affected by factors such as the patient's sweat, and its viscosity will weaken over time, thus gradually losing the binding force on the urinary catheter, and ultimately leading to the loosening of the urinary catheter and even the risk of tube dislodgment. Therefore, medical staff need to check frequently, which increases the workload of medical staff. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a urinary catheter fixing device, which has a longer fixing time compared with using adhesive tape to fix the urinary catheter.

[0005] To solve the above technical problem, the utility model adopts the following technical solutions:

[0006] A urinary catheter fixing device includes a base, a splint, a strap and a soft pad; a tube groove for placing the urinary catheter is arranged on the upper surface of the base, and the tube groove extends from the rear surface of the base to the front surface; on both sides of the tube groove on the upper surface of the base, a slot is respectively arranged; the splint is arranged above the tube groove, a clamping groove is arranged on the lower plate surface of the splint, the clamping groove is arranged opposite to the tube groove, and the clamping groove and the tube groove cooperate with each other to clamp the urinary catheter; insertion blocks are arranged on both sides of the splint, and the insertion blocks are inserted into the slots to fix the splint on the base; the strap is arranged on the side wall of the base for fixing the base on the patient's leg; the soft pad is arranged on the lower surface of the base opposite to the tube groove.

[0007] Furthermore, a placement groove is arranged on the side wall of the insertion block far away from the clamping groove, a spring and a ball are arranged in the placement groove, the spring is arranged at the notch of the placement groove, one end of the spring is connected with the ball, and the other end is connected with the bottom wall of the placement groove; a side hole is arranged on the side wall of the base, and the side hole is communicated with the slot. After the insertion block is inserted into the slot, the ball can elastically pop into the side hole.

[0008] The catheter fixing device provided by the utility model has the following beneficial effects:

[0009] 1. When in use, first tightly bind the base to the patient's leg through the strap, then place the catheter in the tube slot, and then insert the insertion block of the splint into the slot on the base, so as to fasten the catheter between the clamping groove and the tube slot. Since the base is already in a fixed state, the catheter is also in a fixed state. Therefore, compared with using ordinary adhesive tape, the fixing device has higher stability, is not affected by sweat, and has a longer fixing time.

[0010] 2. Since a soft pad is provided between the lower surface of the base and the patient's skin, when the catheter is in a fixed state, it does not directly contact the patient's skin, which can effectively avoid the skin being compressed by the catheter. Description of the Drawings

[0016] The following describes the utility model with reference to the drawings. The specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. Without departing from the design spirit of the utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the utility model shall fall within the protection scope of the utility model.

[0017] As Figures 1 to 4 shown, the catheter fixing device of this embodiment includes a base 1, a splint 2, a strap 3 and a soft pad 4.

[0018] The upper surface of the base 1 is provided with a tube groove 11 for placing a urinary catheter, and the tube groove 11 extends from the rear surface to the front surface of the base 1. The upper surface of the base 1 is provided with a slot 12 on both sides of the tube groove 11.

[0019] The clamping plate 2 is arranged above the tube groove 11, and a clamping groove 21 is arranged on the lower plate surface of the clamping plate 2. The clamping groove 21 is arranged opposite to the tube groove 11, and the clamping groove 21 and the tube groove 11 cooperate with each other to clamp the urinary catheter. Specifically in this embodiment, the cross section of the clamping plate 2 is in the shape of "Ω", the concave surface of the clamping plate 2 is the clamping groove 21, and the cross section of the tube groove 11 is in the shape of "C". The gap between the clamping groove 21 and the tube groove 11 is smaller than the diameter of the urinary catheter. After the urinary catheter is placed, the clamping groove 21 and the tube groove 11 will slightly squeeze the tube wall of the urinary catheter, so that the urinary catheter is fixed between the clamping groove 21 and the tube groove 11.

[0020] Insert blocks 22 are provided on both sides of the clamping plate 2. The insert blocks 22 are inserted into the slots 12 to fix the clamping plate 2 on the base 1. Specifically in this embodiment, the side wall of the insert block 22 away from the clamping slot 21 is provided with a placement slot 211, and a spring 5 and a marble 6 are provided in the placement slot 211. The spring 5 is arranged at the notch of the placement slot 211, and one end of the spring 5 is connected to the marble 6, and the other end is connected to the bottom wall of the placement slot 211; the side wall of the base 1 is provided with a side hole 13, and the side hole 13 is connected to the slot 12. After the insert block 22 is inserted into the slot 12, the marble 6 can be elastically ejected into the side hole 13. Two insert blocks 22 are inserted facing the two slots 12. During the insertion process, the marble 6 contacts the inner wall of the slot 12 and shrinks into the placement slot 211. The spring 5 is compressed and generates elastic force. When the lower plate surface of the clamping plate 2 contacts the upper surface of the base 1, the spring 5 releases the elastic force and ejects the marble 6 into the side hole 13 to fix the position of the clamping plate 2 at this time. When the clamping plate 2 needs to be separated from the base 1, the two marbles 6 are pressed so that the two marbles 6 retract into the placement grooves 211 again and are separated from the side holes 13. At this time, the clamping plate 2 is lifted up to separate the clamping plate 2 from the base 1. In order to facilitate lifting the clamping plate 2, a protrusion 23 is provided on the upper plate surface of the clamping plate 2.

[0021] The strap 3 is arranged on the side wall of the base 1, and is used to fix the base 1 on the patient's leg. Specifically in this embodiment, two straps 3 are arranged, one end of each of the two straps 3 is connected to the two sides of the base 1 respectively, and the other ends of the two straps 3 are connected through a connector 7. The connector 7 in this embodiment includes a hidden buckle, wherein the sub-buckle of the hidden buckle is arranged at the end of one of the straps 3, and the female buckle of the hidden buckle is arranged at the end of the other strap 3. The connector 7 can also be a Velcro or an adjustable buckle.

[0022] The cushion 4 is arranged on the lower surface of the base 1 relative to the tube groove 11, which can improve the comfort of the patient.

[0023] When the utility model is in use, first, the base 1 is tightly tied to the patient's leg through the strap 3. Then, the catheter is placed in the tube groove 11. After that, the insertion block 22 of the splint 2 is inserted into the slot 12 on the base 1, so as to fasten the catheter between the clamping groove 21 and the tube groove 11. Since the base 1 is already in a fixed state, the catheter is also in a fixed state. Therefore, compared with using ordinary adhesive tape, the use of this fixing device has higher stability, is not affected by sweat, and has a longer fixing time. Since a soft pad 4 is provided between the lower surface of the base 1 and the patient's skin, the catheter does not directly contact the patient's skin in the fixed state, and can effectively avoid the skin being compressed by the catheter.
