Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a neck drainage tube fixer. Background Art

[0002] During clinical diagnosis and treatment, some critically ill patients will have vascular drainage tubes placed in their necks due to their condition (such as extracorporeal ventricular assist device internal jugular vein catheters, peripheral extracorporeal membrane oxygenation internal jugular vein catheters, and internal carotid artery catheters). Proper fixation of the pipeline is of great clinical value, but there is currently no effective fixation device for this drainage tube on the market. The conventional fixation method is to use tape and gauze to fit part of the drainage tube to the patient's brain for circular wrapping and fixation to prevent clinical adverse events such as folding, twisting, thrombosis, pipeline slippage, and massive bleeding, which can endanger the patient's life in severe cases. Because the drainage tube is relatively thick and the distal pipeline has a certain weight, it is necessary to wrap multiple bandages around the patient's head to relatively stabilize its position. This fixation method causes the patient's head to feel tight and the pipeline is not firmly fixed. Multiple factors have caused the patient's activities to be restricted, which is not conducive to clinical recovery, and the medical experience is poor.

[0003] In view of this, the present invention is designed to solve the above-mentioned problems to serve clinical practice.

[0004] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned shortcomings and provide a neck drainage tube fixer.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The neck drainage tube fixer comprises a basic fixing part, which comprises a top frame placed on the top of the head, a forehead pillow pad fixedly arranged on the top frame for supporting the forehead, and a rear clamping arm rotatably arranged on the top frame for cooperating with the forehead pillow pad to clamp the head front and back from the lower side of the occipital convexity; a clamping assembly arranged on the top frame for clamping and fixing the drainage tube; and an adjusting assembly arranged on the top frame for controlling the rotation of the rear clamping arm.

[0008] Furthermore, a first bearing frame is arranged on the top frame, and the rear clamping arm includes a connecting rod rotatably arranged on the first bearing frame and a back head pad arranged at both ends of the connecting rod; the connecting rod is connected to the back head pad in a form that avoids the occipital bulge.

[0009] Furthermore, a fixing frame is provided at the side end of the top frame, and the clamping assembly includes a sleeve fixed on the fixing frame, a limiting slide rod movably connected to the sleeve, a clamping plate provided on the limiting slide rod for cooperating with the sleeve to clamp the drainage tube, a limiting frame provided on the outside of the sleeve, and a first threaded rod bolted to the limiting frame and clamped with a bearing at one end of the limiting slide rod away from the clamping plate.

[0010] Furthermore, the adjustment assembly includes a driving unit and a transmission unit arranged between the driving unit and the connecting rod.

[0011] Furthermore, second bearing frames are arranged on both sides of the top frame, and the driving unit includes a second threaded rod rotatably connected to the second bearing frame at both ends, a sleeve block threadedly sleeved with the second threaded rod, a first wedge block arranged on the sleeve block, and a rotating head arranged at the end of the second threaded rod; a limiting cross bar is arranged between the second bearing frames, and a limiting sliding groove is opened on the sleeve block for sliding engagement with the limiting cross bar.

[0012] Furthermore, a cross bar is arranged between the top frames, a third bearing frame is arranged on the cross bar, and the transmission unit includes a seesaw plate arranged on the third bearing frame through a movable shaft, a connecting rod hinged at the end of the seesaw plate, a connecting plate hinged at the end of the connecting rod away from the seesaw plate, and a second wedge block arranged on the lower surface of the connecting plate and adapted to abut against the first wedge block; a movable hole for the connecting rod to move is opened at the end of the seesaw plate away from the connecting rod; and limit baffles are arranged on both sides of the limit cross bar to limit the second wedge block so that it can only move up and down.

[0013] Furthermore, the connecting rod is also sleeved with a torsion spring having one end arranged on the first bearing frame and the other end arranged on the connecting rod.

[0014] Furthermore, it also includes a pulling component, a limiting slot is provided on the sleeve block, and a limiting block is provided at the lower end of the first wedge block and is slidably engaged in the limiting slot; the pulling component includes a connecting rope provided on the first wedge block and a locking belt provided at one end of the connecting rope away from the first wedge block and with Velcro on the upper end.

[0015] Furthermore, a groove for the connecting rope to pass through is formed at the lower end of the second wedge block, and a limiting sleeve frame is provided on the top frame, which is sleeved on the outside of the connecting rope and is used to limit the moving trajectory of the connecting rope.

[0016] Furthermore, an elastic cushion belt is also arranged in the top frame.

[0017] Compared with the prior art, the beneficial effect of the present solution is that the present invention improves the convenience of fixation by being worn on the patient's head and using the clamping assembly thereon to fix the neck drainage tube. At the same time, the front and rear end clamping structure also avoids the overall wrapping of the patient's head, making the patient more comfortable to wear without affecting their normal activity state.

[0018] The present invention additionally provides a pulling component on the adjusting component, thereby being able to additionally sleeve and fix the upper side of the clamped portion of the drainage tube, and additionally increase the clamping force on the head when the drainage tube is deviated toward the outside of the brain, thereby enhancing the overall stability and preventing the drainage tube from being easily loosened from the clamping component.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0039] like Figure 1-17The neck drainage tube fixer shown includes a basic fixing part, which includes a top frame 1 placed on the top of the head, a forehead pillow pad 11 fixedly set on the top frame 1 for supporting the forehead, and a rear clamping arm 12 rotatably set on the top frame 1. The top frame 1 is equipped with a movably detachable shell 8 to conceal the internal structure and improve the overall aesthetics of the product; it also has a clamping component set on the top frame 1 for clamping and fixing the drainage tube; it also has an adjustment component set on the top frame 1 for controlling the rotation of the rear clamping arm 12. The fixer is worn on the patient's head and uses the forehead pillow pad 11 and the rear clamping arm 12 to clamp and fix the patient's head. The clamping arm 12 is set to two groups to clamp from both sides below the occipital bulge to adapt to the support of different head shapes. (The inner sides of the forehead pillow 11 and the clamping arm 12 are made of a material with relatively large friction and elasticity, such as rubber, to ensure that it can generate greater friction without slipping after clamping the patient's head. At the same time, it also has a large thickness so that it can deform under the clamping pressure state to adapt to the patient's skin surface). Then, the drainage tube body on the patient's neck is clamped by the clamping assembly on the top frame 1, so that the patient's head is used as an additional fulcrum to fix the drainage tube, avoiding the drainage tube from moving away from the patient and generating tension, causing the drainage port to loosen. This fixing method eliminates the tedious steps of wrapping and fixing with gauze, and also improves the patient's comfort, making it less likely for the patient to resist.

[0040] In one embodiment, a first bearing frame 20 is provided on the top frame 1, and the rear clamping arm 12 includes a connecting rod 2 rotatably arranged on the first bearing frame 20 and a back head pad 21 arranged at both ends of the connecting rod 2; the connecting rod 2 is connected to the back head pad 21 in a shape that avoids the occipital bulge. Since there is an occipital bulge at the rear end of the patient's brain, when the back head pad 21 is clamped here, it will cause insufficient overall stability. Therefore, the back head pad 21 is set at a position below the occipital bulge for support and clamping. This is the back of the patient's head. Therefore, when the patient lies down, a certain gap will be formed here with the pillow part, which can reduce the patient's discomfort. The material of the connecting rod 2 is a relatively hard metal material to ensure the stability of the clamping of the back head pad 21. At the same time, the overall shape of the connecting rod 2 is set to extend from both sides of the top frame 1 toward the patient's ear side and then downward, and then extend obliquely backward to the lower side of the occipital bulge, so as to avoid the discomfort caused by the hard object being supported when the connecting rod 2 directly extends from the back of the head to the lower side of the occipital bulge.

[0041] In one embodiment, a fixing frame 3 is provided at the side end of the top frame 1, and the clamping assembly includes a sleeve 31 fixed on the fixing frame 3, a limiting slide bar 32 movably connected to the sleeve 31, a splint 33 provided on the limiting slide bar 32 for cooperating with the sleeve 31 to clamp the drainage tube, a limiting frame 34 provided on the outside of the sleeve 31, and a first threaded rod 35 bolted to the limiting frame 34 and bearing-engaged with the end of the limiting slide bar 32 away from the splint 33. The drainage tube extends from the patient's neck and extends upward along the side end of the brain to the drainage device, and then the drainage tube section passing through the patient's brain side is placed in the sleeve 31, and the first threaded rod 35 is rotated so that it drives the splint 33 to clamp the outer wall of the tube body through the limiting slide bar 32, thereby fixing the tube body.

[0042] In one embodiment, the adjustment component includes a driving unit and a transmission unit arranged between the driving unit and the connecting rod 2, second bearing frames 4 are arranged on both sides of the top frame 1, the driving unit includes a second threaded rod 41 rotatably connected to the second bearing frame 4 at both ends, a sleeve block 42 threadedly sleeved with the second threaded rod 41, a first wedge block 43 arranged on the sleeve block 42, and a rotating head 44 arranged at the end of the second threaded rod 41; a limiting cross bar 45 is arranged between the second bearing frames 4, and a limiting slide groove 46 is provided on the sleeve block 42 for sliding engagement with the limiting cross bar 45; a cross frame rod 5 is arranged between the top frames 1, and a third bearing frame 51 is arranged on the cross frame rod 5, and the transmission unit includes a seesaw 53 rotatably arranged on the third bearing frame 51 through a movable shaft, a connecting rod 54 hinged at the end of the seesaw 53, and a connecting plate 5 hinged at the end of the connecting rod 54 away from the seesaw 53. The second wedge 56 is arranged on the lower surface of the connecting plate 55 and is adapted to abut against the first wedge 43; a movable hole 57 for the connecting rod 2 to move is opened at one end of the seesaw 53 away from the connecting rod 54; and limiting baffles 58 are arranged on both sides of the limiting cross bar 45 to limit the second wedge 56 so that it can only move up and down. By rotating the rotating head 44, the second threaded rod 41 is driven to rotate, so that the sleeve block 42 slides on the limiting cross bar 45, and the first wedge 43 at its upper end pushes the second wedge 56 to move upward, and then the connecting plate 55 and the connecting rod 54 drive one end of the seesaw 53 to tilt up, so that the other end drives the connecting rod 2 to press down, and then the connecting rod 2 rotates with the hinged part with the first bearing frame 20 as the center of the circle, so that the back of the head pad 21 at its lower end moves to the lower side of the patient's occipital convexity, and then cooperates with the forehead pillow pad 11 to clamp the patient's head.

[0043] In one embodiment, the connecting rod 2 is also sleeved with a torsion spring 22, one end of which is arranged on the first bearing frame 20 and the other end of which is arranged on the connecting rod 2. Through the arrangement of the torsion spring 22, the connecting rod 2 can automatically rotate and reset under normal conditions.

[0044] In one embodiment, a pulling assembly is also included. A limiting card slot 6 is provided on the sleeve block 42. A limiting card block 61 is provided at the lower end of the first wedge block 43 and is slidably engaged in the limiting card slot 6. The pulling assembly includes a connecting rope 62 provided on the first wedge block 43 and a locking belt 63 provided at the end of the connecting rope 62 away from the first wedge block 43. The locking belt 63 is provided with Velcro. When the body of the drainage tube is fixed on the jacket 31, the locking belt 63 is wound around the upper part of the clamped section of the tube body, and then when the tube body moves away from the patient's brain, the locking belt 63 is provided. When there is a tendency to deviate in the side direction, the first wedge block 43 will be driven to slide on the sleeve block 42 through the connecting rope 62, so that the first wedge block 43 continues to support the second wedge block 56. At this time, the back of the head pad 21 is further clamped on the patient's brain, and the brain is used as a fulcrum. The tube body is pulled and restrained by the reverse force of the connecting rope 62, making it difficult for it to detach from the side of the sleeve 31, and then the two-point fixing method is used to ensure that there is no tension in the tube section from the fixed point to the neck of the drainage tube, thereby enhancing the fixing stability of the tube body.

[0045] In one embodiment, a groove 64 is formed at the lower end of the second wedge block 56 for the connecting rope 62 to pass through, and a limiting sleeve 65 is provided on the fixed frame 3 and is sleeved on the outside of the connecting rope 62. The limiting sleeve 65 is provided to limit the movement trajectory of the connecting rope 62 so that it will not interfere with the movement of other structures on the top frame 1, and at the same time, the pulling direction of the connecting rope 62 on the locking belt 63 is kept horizontal.

[0046] In one embodiment, an elastic pad belt 7 is further provided in the top frame 1. The elastic pad belt 7 is made of a soft material with high friction, such as rubber, to ensure that it generates sufficient friction with the top of the patient. The top frame 1 is hollow as a whole, thereby reducing its weight. At the same time, the elastic pad belt 7 is used to fit the top of the patient's skull, which strengthens the stability of the top frame 1 and the brain while also improving the wearing comfort of the patient.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
