Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an external ventricular drainage tube and an intracranial pressure probe fixation device. Background Technology

[0002] Currently, neurological diseases are prevalent, and a large number of patients with neurological diseases require external ventricular drainage every year. External ventricular drainage is one of the common surgical treatment options for diseases such as craniocerebral trauma and intracranial hemorrhage. External ventricular drainage involves inserting an external ventricular drainage tube into the ventricle after puncturing the skull. The opening end of the drainage tube is located in the ventricle, and excess cerebrospinal fluid or blood is drained out of the ventricle through the drainage tube. The fluid then flows through the drainage tube into a drainage bottle and then into a collection bag for collection.

[0003] However, when using double fixation to secure the drainage tube and negative pressure tube after external ventricular drainage surgery, the double fixation with adhesive tape is prone to falling off, requiring frequent checks and fixation. Furthermore, the adhesive tape is also prone to falling off, requiring repeated fixation, which is cumbersome and can easily cause pain to the patient or loosening of the tube end, affecting its use. In addition, the adhesive tape is not secure enough, which can easily lead to tube dislodgement. The overall fixation is also messy and affects the appearance. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a device for fixing an external ventricular drainage tube and an intracranial pressure probe. This device offers advantages such as easy separate fixing of the drainage tube and negative pressure tube, good overall fixation, resistance to loosening, prevention of pipe loosening affecting use, easy inspection after overall fixation, and minimal messiness affecting aesthetics. It also facilitates the fixation of the intracranial pressure probe, preventing patient agitation from causing the ventricular drainage tube and intracranial pressure probe to dislodge. Furthermore, it offers the advantages of convenient assembly and disassembly, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an external ventricular drainage tube and an intracranial pressure probe fixing device, comprising a side plate and a top plate, an adjustment assembly being provided between the side plate and the top plate, a fixing mechanism being provided on the outer side of the side plate and the top plate respectively, a connecting line being provided on the bottom side of the top plate, a probe fixing assembly being provided at the end of the connecting line away from the top plate, and an intracranial pressure probe body being sleeved on the inner side of the probe fixing assembly.

[0008] Preferably, breathable soft pads are fixedly installed on the inner sides of the side panels and the top panel, and a first fixing strap and a second fixing strap are fixedly installed on the bottom side of the side panels respectively. The first fixing strap and the second fixing strap are Y-shaped, and the right side of the first fixing strap and the second fixing strap are respectively provided with a Velcro round surface and a Velcro barbed surface.

[0009] With the above technical solution, when in use, the fixing sleeve formed by the side plate and the top plate is fastened to the outside of the patient's head. Then, the first fixing strap and the second fixing strap are pulled respectively and fixed by the round surface and the barbed surface of the Velcro. The fixing is convenient and quick. At this time, with the help of the breathable soft pad, it helps to improve the comfort and breathability of the device after fixing and the patient's fit, thereby avoiding stuffiness that may cause discomfort or allergies at the fitting position.

[0010] Preferably, the adjustment assembly includes a cavity, a limiting rod, and a first fastening spring. Two sets of cavities are respectively opened on the top side of the side plate. A limiting rod is provided inside the cavity. A first fastening spring is fixedly installed between the limiting rod and the cavity. A top plate is fixedly installed at the end of the limiting rod away from the cavity.

[0011] With the above technical solution, during the fixation process, when adjustment is needed, the two sets of side plates can be pulled separately, so that the limiting rod can move inside the cavity, thereby facilitating the adjustment of the size of the fixation sleeve. This is beneficial for adjusting according to the size of the patient's head and has high applicability.

[0012] Preferably, the fixing mechanism includes a sleeve, an inner cylinder, a first fixing seat, a second fixing seat, and a disassembly mechanism. The inner cylinder is sleeved on the inner side of the sleeve. The second fixing seat and the first fixing seat are fixedly installed on the left and right sides of the outer sides of the sleeve and the inner cylinder, respectively. Limiting grooves are formed on the opposite sides of the second fixing seat and the first fixing seat. Anti-slip pads are fixedly installed on the inner side of the limiting grooves.

[0013] With the above technical solution, when fixing the drainage tube and the two sets of negative pressure tubes, the drainage tube and the two sets of negative pressure tubes are respectively inserted into the outer end of the limiting groove and pulled out from the inclined end of the first fixing seat. Then, the inner cylinder is pressed, so that the push rod pushes out the disassembly seat under the action of the first return spring. At this time, the drainage tube and the two sets of negative pressure tubes are limited and fixed by the anti-slip pad between the first fixing seat and the second fixing seat. This helps to avoid the drainage tube and the two sets of negative pressure tubes being messy and affecting the appearance. The fixing is convenient and quick, and the overall fixing effect is good.

[0014] Preferably, two sets of disassembly mechanisms are respectively provided between the sleeve and the inner cylinder. The disassembly mechanism includes a push rod, a disassembly seat, a pressing head, a first return spring, and a second return spring. Push rods are movably installed on the left and right sides of the inner cylinder, and a first return spring is fixedly installed between the push rod and the inner cylinder. A disassembly seat is movably installed on the outer side of the sleeve, and a second return spring is fixedly installed between the disassembly seat and the sleeve support. The elastic force of the second return spring is less than that of the first return spring. A pressing head is fixedly installed on the opposite side of the push rod and the disassembly seat.

[0015] With the above technical solution, when it is necessary to remove the drainage tube or the two sets of negative pressure tubes, the two sets of disassembly seats are squeezed at the same time, thereby pushing out the top rod through the squeezing head, and then the inner cylinder drives the No. 1 fixed seat to return to its original position, making it convenient to remove the drainage tube and the two sets of negative pressure tubes. The disassembly and assembly are convenient and quick.

[0016] Preferably, the probe fixing assembly includes a rubber seat, a through hole, an adhesive layer, and a fastening mechanism. The rubber seat has a through hole on its top side, a fastening mechanism is provided inside the through hole, and an adhesive layer is provided on the bottom side of the rubber seat.

[0017] With the above technical solution, when the intracranial pressure probe body is inserted into the patient's skin, the insertion end of the intracranial pressure probe body is passed through the through hole, and then the insertion surgery is performed. After the insertion is completed, the adhesive layer is fixed to the patient's scalp. At this time, the anti-slip seat is reset under the action of the second fastening spring, thereby fixing and limiting the insertion end of the intracranial pressure probe body. This helps to improve the fixation effect and avoid the intracranial pressure probe body shaking during use, which may cause pain to the patient or affect the insertion hole.

[0018] Preferably, the fastening mechanism includes an anti-slip seat, a connecting rod, a pull ring, and a second fastening spring. There are two anti-slip seats in total. Several sets of second fastening springs are fixedly installed between the anti-slip seat and the rubber seat. The left end of the connecting rod is fixedly installed with an anti-slip seat, and the right end of the connecting rod is fixedly installed with a pull ring. The connecting rod is a movable connection structure.

[0019] With the above technical solution, when it is necessary to remove the intracranial pressure probe body, pull the pull ring, thereby moving the connecting rod and anti-slip seat, thereby loosening the insertion end of the intracranial pressure probe body, and thus making it easier to remove the probe body.

[0020] Compared with the prior art, the present invention provides an external ventricular drainage tube and an intracranial pressure probe fixation device, which has the following beneficial effects:

[0021] 1. This invention uses a fixing sleeve formed by the side plates and top plate to fit the patient's head. Then, the first and second fixing straps are pulled and fixed using the round and barbed surfaces of the Velcro. The fixing is convenient and quick. The breathable soft pad helps to improve the comfort and breathability of the device after fixing, thus avoiding stuffiness that could cause discomfort or allergies at the fitting position. Furthermore, during the fixing process, when adjustment is needed, the two sets of side plates can be pulled to move the limiting rod inside the cavity, thus facilitating the adjustment of the size of the fixing sleeve. This allows for adjustment according to the size of the patient's head, making it highly adaptable.

[0022] 2. When the intracranial pressure probe body is inserted into the patient's skin, the present invention first passes the insertion end of the intracranial pressure probe body through the through hole, and then performs the insertion surgery. After the insertion is completed, the adhesive layer is fixed to the patient's scalp. At this time, the anti-slip seat is reset under the action of the second fastening spring, thereby fixing and limiting the insertion end of the intracranial pressure probe body. This helps to improve the fixation effect and avoid the intracranial pressure probe body shaking during use, which may cause the patient to feel discomfort or affect the insertion hole. When it is necessary to remove the intracranial pressure probe body, the pull ring is pulled to move the connecting rod and the anti-slip seat, thereby loosening the insertion end of the intracranial pressure probe body for easy removal.

[0023] 3. This invention involves inserting the drainage tube and two sets of negative pressure tubes into the outer end of the limiting groove and pulling them out from the inclined end of the first fixing seat. Then, pressing the inner cylinder causes the push rod to push out the disassembly seat under the action of the first return spring. At this time, the anti-slip pad between the first and second fixing seats limits and fixes the drainage tube and the two sets of negative pressure tubes, which helps to avoid the drainage tube and the two sets of negative pressure tubes being messy and affecting the appearance. The fixing is convenient and quick, and the overall fixing effect is good. When it is necessary to remove the drainage tube or the two sets of negative pressure tubes, the two sets of disassembly seats are squeezed at the same time, so that the push rod is pushed out through the squeezing head. Then, the inner cylinder drives the first fixing seat to return to its original position, making it easy to remove the drainage tube and the two sets of negative pressure tubes.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] like Figure 1-6 As shown, the present invention provides an external ventricular drainage tube and an intracranial pressure probe fixing device, including a side plate 1 and a top plate 2. An adjustment component 3 is provided between the side plate 1 and the top plate 2. Fixing mechanisms 4 are respectively provided on the outer sides of the side plate 1 and the top plate 2. A connecting line 5 is provided on the bottom side of the top plate 2. A probe fixing component 6 is provided at the end of the connecting line 5 away from the top plate 2. An intracranial pressure probe body 7 is sleeved on the inner side of the probe fixing component 6.

[0034] Specifically, breathable pads 101 are fixedly installed on the inner sides of the side panels 1 and the top panel 2. A first fixing strap 102 and a second fixing strap 103 are fixedly installed on the bottom side of the side panels 1. The first fixing strap 102 and the second fixing strap 103 have a Y-shaped structure, and their right sides are respectively provided with a round hook-and-loop fastener and a barbed hook-and-loop fastener. The advantage is that by fastening the fixing sleeve formed by the side panels 1 and the top panel 2 to the outside of the patient's head, and then pulling the first fixing strap 102 and the second fixing strap 103 to secure them using the round hook-and-loop fastener and the barbed hook-and-loop fastener, the fastening is convenient and quick. At this time, the breathable pads 101 help improve the comfort and breathability of the device after fixation, thus avoiding stuffiness that could cause discomfort or allergies at the contact point.

[0035] Specifically, the adjustment component 3 includes a cavity 301, a limiting rod 302, and a first fastening spring 303. Two cavities 301 are respectively formed on the top side of the side plate 1. A limiting rod 302 is provided inside each cavity 301, and a first fastening spring 303 is fixedly installed between the limiting rod 302 and the cavity 301. A top plate 2 is fixedly installed at the end of the limiting rod 302 away from the cavity 301. The advantage is that by pulling the two sets of side plates 1 respectively, the limiting rod 302 can move inside the cavity 301, thus facilitating the adjustment of the size of the fixing sleeve. This allows for adjustment according to the patient's head size, resulting in high applicability.

[0036] Specifically, the fixing mechanism 4 includes a sleeve 401, an inner cylinder 402, a first fixing seat 403, a second fixing seat 404, and a disassembly mechanism 405. The inner cylinder 402 is sleeved on the inner side of the sleeve 401. The second fixing seat 404 and the first fixing seat 403 are fixedly installed on the left and right sides of the outer sides of the sleeve 401 and the inner cylinder 402, respectively. Limiting grooves 4031 are opened on the opposite sides of the second fixing seat 404 and the first fixing seat 403. An anti-slip pad is fixedly installed on the inner side of the limiting groove 4031. The advantage is that by inserting the drainage tube and the two sets of negative pressure tubes into the outer end of the limiting groove 4031 respectively, and pulling them out from the inclined end of the first fixing seat 403, and then pressing the inner cylinder 402, the push rod 4051 pushes out the disassembly seat 4052 under the action of the first return spring 4054. At this time, the anti-slip pad between the first fixing seat 403 and the second fixing seat 404 limits and fixes the drainage tube and the two sets of negative pressure tubes, which helps to avoid the drainage tube and the two sets of negative pressure tubes being messy and affecting the appearance. Moreover, the fixing is convenient and quick, and the overall fixing effect is good.

[0037] Example 2:

[0038] like Figure 1-6As shown, as an improvement on the previous embodiment, specifically, two sets of disassembly mechanisms 405 are respectively provided between the sleeve 401 and the inner cylinder 402. The disassembly mechanism 405 includes a push rod 4051, a disassembly seat 4052, a pressing head 4053, a first return spring 4054, and a second return spring 4055. The push rod 4051 is movably installed on the left and right sides of the inner cylinder 402, and the first return spring 4054 is fixedly installed between the push rod 4051 and the inner cylinder 402. The disassembly seat 4052 is movably installed on the outer side of the sleeve 401, and the second return spring 4055 is fixedly installed between the disassembly seat 4052 and the sleeve 401 bracket. The elastic force of the second return spring 4055 is less than the elastic force of the first return spring 4054. A pressing head 4053 is fixedly installed on the opposite side of the push rod 4051 and the disassembly seat 4052. The advantage is that by simultaneously squeezing the two sets of disassembly seats 4052, the top rod 4051 is pushed out through the squeezing head 4053, and then the inner cylinder 402 drives the first fixed seat 403 to return to its original position, making it convenient to remove the drainage tube and the two sets of negative pressure tubes. The disassembly and assembly are convenient and quick.

[0039] Specifically, the probe fixing assembly 6 includes a rubber base 601, a through hole 602, an adhesive layer 603, and a fastening mechanism 604. The rubber base 601 has a through hole 602 on its top side, a fastening mechanism 604 inside the through hole 602, and an adhesive layer 603 on its bottom side. The advantage is that by passing the insertion end of the intracranial pressure probe body 7 through the through hole 602, followed by the insertion surgery, and then fixing the adhesive layer 603 to the patient's scalp after insertion, the anti-slip base 6041 is reset under the action of the second fastening spring 6044, thereby fixing and limiting the insertion end of the intracranial pressure probe body 7. This improves the fixation effect and prevents the intracranial pressure probe body 7 from shaking during use, which could cause pain to the patient or affect the insertion hole.

[0040] Specifically, the fastening mechanism 604 includes an anti-slip seat 6041, a connecting rod 6042, a pull ring 6043, and a second fastening spring 6044. Two anti-slip seats 6041 are provided. Several sets of second fastening springs 6044 are fixedly installed between the anti-slip seat 6041 and the rubber seat 601. The left end of the connecting rod 6042 is fixedly installed with the anti-slip seat 6041, and the right end of the connecting rod 6042 is fixedly installed with the pull ring 6043. The connecting rod 6042 is a movable connection structure. The advantage is that by pulling the pull ring 6043, the connecting rod 6042 and the anti-slip seat 6041 can be moved, thereby loosening the insertion end of the intracranial pressure probe body 7 for easy removal.

[0041] In use, the fixing sleeve formed by the side plate 1 and the top plate 2 is fastened to the outside of the patient's head. Then, the first fixing strap 102 and the second fixing strap 103 are pulled respectively and fixed by the round and barbed surfaces of the Velcro. The fixing is convenient and quick. At this time, the breathable soft pad 101 helps to improve the comfort and breathability of the device after fixing, thereby avoiding stuffiness that may cause discomfort or allergies at the fitting position. Furthermore, during the fixing process, when adjustment is needed, the two sets of side plates 1 can be pulled respectively, so that the limiting rod 302 is within the cavity 301. The device can be moved to the side to facilitate adjustment of the size of the fixation sleeve, making it suitable for different head sizes and highly adaptable. Next, when the intracranial pressure probe body 7 is inserted into the patient's skin, the insertion end of the probe body 7 is first passed through the through hole 602, followed by the insertion procedure. After insertion, the adhesive layer 603 is fixed to the patient's scalp. At this time, the anti-slip seat 6041 is reset under the action of the second fastening spring 6044, thus fixing and limiting the insertion end of the intracranial pressure probe body 7, which helps improve the fixation effect and avoids overuse. If the intracranial pressure probe body 7 shakes during the procedure, causing pain to the patient or affecting the insertion hole, and it is necessary to remove the intracranial pressure probe body 7, pull the pull ring 6043 to move the connecting rod 6042 and the anti-slip seat 6041, thereby loosening the insertion end of the intracranial pressure probe body 7 for easy removal. Then, insert the drainage tube and the two sets of negative pressure tubes into the outer end of the limiting groove 4031 respectively, and pull them out from the inclined end of the first fixing seat 403. Then press the inner cylinder 402, so that the top rod 4051, under the action of the first return spring 4054, will release the disassembly seat 4. When the 052 is ejected, the drainage tube and the two sets of negative pressure tubes are limited and fixed by the anti-slip pad between the first fixing seat 403 and the second fixing seat 404. This helps to prevent the drainage tube and the two sets of negative pressure tubes from being messy and affecting the appearance. The fixing is convenient and quick, and the overall fixing effect is good. When it is necessary to remove the drainage tube or the two sets of negative pressure tubes, the two sets of disassembly seats 4052 are squeezed at the same time. Then, the extrusion head 4053 pushes out the push rod 4051, and then the inner cylinder 402 drives the first fixing seat 403 to return to its original position, making it convenient to remove the drainage tube and the two sets of negative pressure tubes. The disassembly and assembly are convenient and quick.
