Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a replaceable intracranial pressure monitoring wire fixator. Background Technique
[0002] Clinically, when the patient's condition requires or after undergoing surgery, since it is necessary to analyze the changes in the patient's intracranial pressure to help judge the patient's injury and the condition of cerebral edema, the intracranial pressure monitor implantation technology is often required. However, the intracranial pressure monitoring wire is long, thin and fragile. Coupled with the fact that the heads of general patients after craniotomy are wrapped with a lot of dressings, the existing clinical fixation techniques mostly use adhesive stickers or films for fixation. When replacing the adhesive stickers and films, it is easy to pull the wire, increasing the risk of breakage, which is not conducive to observing the patient's condition. At the same time, when the patient changes dressings after surgery, it is necessary to re-fix, increasing the clinical workload; and if it is adhesively fixed on the patient's skin, it is easy to produce oil and affect the adhesiveness, and there is not much exposed skin on the patient's head. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is that the existing intracranial pressure monitoring wire is adhesively fixed on the dressing, and the wire is easily pulled when the dressing is replaced, increasing the risk of breakage, and there are also many inconveniences in directly adhesively fixing on the skin surface; in view of the above problems, a replaceable intracranial pressure monitoring wire fixator is proposed, which includes a base and a fixator. The lower surface of the base is provided with an adhesive sticker for fixation, and two buckle inserts are arranged in parallel on the upper surface of the base. Two slots are arranged in the fixator, and the buckle inserts are inserted into the slots, and the buckle inserts are flush with the side wall of the fixator. The upper surface of the fixator is provided with a fixing buckle for installing a sensor, and a plurality of wire clips are evenly arranged on the upper surface of the fixator.
[0004] The technical solution of the utility model, through the structure that the base and the fixator are connected by a snap-in connection, when the patient changes the dressing, the base is replaced together, and at the same time, the new base is adhered to the replaced dressing, and then the fixator is connected to the new base. The replacement process does not affect the wire and reduces the risk of breakage; by arranging a frosted bump on the inner wall of the fixing buckle, the friction force is increased after the sensor is snapped in, reducing the shaking and reducing the pulling effect on the wire; by arranging wire clips on the surface of the fixator, the wire clips are evenly distributed around the surface of the fixator, so that the wire is coiled and fixed on the surface of the fixator, preventing the wire from being entangled or pulled, and at the same time, the convex teeth in the wire clip can prevent the wire from falling off from the wire clip.
[0005] Preferably, the slots are provided with limit blocks at the edges of the fixator, and the limit blocks are used to engage the buckle inserts to prevent the buckle inserts from shaking.
[0006] Preferably, the front wall of the end of the buckle insert fits with the limit block, and after the buckle insert fits with the limit block through elastic deformation, it is caught by the limit block.
[0007] For the optimization of the technical solution of the present utility model, a clamping groove is provided at the entrance of the slot of the fixator, and the connecting end of the insertion buckle and the base is clamped into the clamping groove. After the insertion buckle is clamped into the clamping groove, it is flush with the surface of the fixator without protruding, presenting a neat and dexterous appearance.
[0008] For the optimization of the technical solution of the present utility model, convex teeth are provided on both inner side walls of the wire clamp, and the convex teeth all face inwards. The convex teeth are used to clamp the wire to prevent the wire from breaking due to slipping out of the wire clamp.
[0009] For the optimization of the technical solution of the present utility model, there is a certain distance between the two convex teeth, and this distance is smaller than the diameter of the wire. Through the elastic deformation of the wire clamp, the distance is enlarged. After the wire is clamped into it, the wire clamp returns to its original state, and the wire cannot slip out of the wire clamp.
[0010] For the optimization of the technical solution of the present utility model, convex points for increasing friction are provided on the inner wall of the fixing buckle. The fixing opening is used to fix the sensor, and the convex points increase the friction to prevent the sensor from falling out of the fixing buckle and pulling the wire to cause breakage.
[0011] The beneficial effects of the present utility model compared with the prior art are as follows:
[0012] In the technical solution of the present utility model, through the plug-in connection structure of the base and the fixator, when the patient changes the dressing, the base is replaced together. At the same time, the new base is adhered to the replaced dressing, and then the fixator is connected to the new base. The wire is not affected during the replacement process, reducing the risk of breakage; by providing matte-like convex points on the inner wall of the fixing buckle, the friction is increased after the sensor is clamped, reducing shaking and the pulling effect on the wire; by providing a wire clamp on the surface of the fixator, the wire clamps are evenly distributed around the surface of the fixator, so that the wire is coiled and fixed on the surface of the fixator, preventing the wire from being entangled or pulled. At the same time, the convex teeth in the wire clamp can prevent the wire from falling out of the wire clamp. Description of the Drawings

[0018] The following will combine the drawings in the embodiments of the present utility model Figures 1-4 to describe in detail the technical solutions in the embodiments of the present utility model. Embodiment 1
[0019] As Figures 1-4 shown, the present utility model is a replaceable intracranial pressure monitoring wire fixator, which includes a base 1 and a fixator 2. The base 1 is adhered to the dressing on the patient's head, and the fixator 2 is used to fix the sensor and the wire. The connection between the fixator 2 and the base 1 is detachable. When changing the dressing, the base 1 and the dressing are replaced together. After changing the dressing, the fixator 2 is connected to the new base 1, reducing the disassembly and assembly of the wire and reducing the risk of wire breakage.
[0020] The bottom of the base 1 is an adhesive patch 12 for adhering to the dressing. The adhesive patch 12 covers the entire bottom of the base 1, and the adhesive fixation is stable, avoiding shaking or even falling off. Two snap buttons 11 are fixedly arranged on the upper surface of the base 1, and the snap buttons 11 are parallel to each other.
[0021] A slot 23 matching the snap button 11 is opened inside the fixator 2. The two sides of the slot 23 are limit blocks 21. The snap button 11 is inserted into the slot 23 through elastic deformation, and its end extends outward to form a convex block. When the snap button 11 is inserted in place, due to the elastic deformation, the snap button 11 returns to its original shape, so that the front wall of the convex block fits against the limit block 21 and is flush with the side wall of the fixator 2. The snap button 11 is clamped in the slot 23, completing the connection between the fixator 2 and the base 1.
[0022] The fixator 2 is recessed to form a card slot 22 at the entrance of the slot 23. When the snap button 11 is inserted in place, the connection end of the snap button 11 and the base 1 is snapped into the card slot 22. At this time, the surfaces of the base 1 and the fixator 2 are both flush, without any protrusions, smooth and flat.
[0023] A fixing buckle 25 is fixedly installed on the upper surface of the fixator 2. The fixing buckle 25 is used to install the sensor. The inner wall of the fixing buckle 25 is provided with convex points to increase friction and prevent the sensor from falling out of the fixing buckle 25.
[0024] Three wire clips 24 are also fixedly installed on the upper surface of the fixator 2. The wire clips 24 and the fixing buckle 25 are distributed around the upper surface of the fixator 2. The wire head of the wire is placed inside the patient's skull, and the other end is connected to the sensor. The redundant wire exposed outside is coiled and fixed by the wire clip 24, and then the sensor is fixed in the fixing buckle 25, reducing the pulling of the wire and preventing breakage.
[0025] The wire clamp 24 is in the shape of a "匚" with its opening facing upward. Convex teeth 241 are fixedly arranged on both side walls inside the wire clamp 24. The cross section of the convex teeth 241 is triangular. The convex teeth 241 are arranged in a mirror image, and the two vertices are close to each other. The distance between the two vertices is slightly smaller than the diameter of the wire. When the wire needs to be inserted, the elastic deformation of the wire clamp 24 causes the two side walls to face outward, and the distance between the two convex teeth 241 increases. After the wire is inserted, the wire clamp 24 returns to its original state due to the elastic deformation, and the wire cannot be detached.
[0026] The base 1 and the fixture 2 are made of plastic, are integrally formed parts, and each structure has a certain elastic deformation capability.
[0027] A method of using a replaceable intracranial pressure monitoring wire fixator of this embodiment is as follows:
[0028] First, insert the patient's intracranial pressure monitoring wire into the wire card 24 in a ring shape along the wire card 24 on the upper surface of the fixator 2, then insert the sensor connected to the monitoring wire into the fixing buckle 25 on the upper surface of the fixator 2, and then insert the fixator 2 into the slot 23 of the base 1 through the buckle 11 to fix the fixator 2 to the base 1. Finally, tear off the protective film on the adhesive sticker 12 at the bottom of the base 1, and stick the entire device on the dressing adhered to the patient's head, so as to effectively fix it.
[0029] When it is necessary to change the dressing, pinch the buckle 11 with both hands to make it elastically deform and disengage from the slot 23, separate the fixer from the base 1, remove the dressing and the base 1 together and discard them. After the dressing change is completed, take a new base 1, connect it to the fixer 2, and then tear off the protective film on the adhesive tape 12 to complete the re-fixation of the device. There is no need to remove the old base 1 for recycling, which reduces the labor of medical staff and avoids the problem of unstable fixation caused by insufficient viscosity of the adhesive tape 12 when it is peeled off and glued again.
[0030] The above embodiments are only for illustrating the technical idea of the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
