Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to an external drainage device for facilitating the adjustment of the height of a drainage drip bottle. Background Art

[0002] External drainage of cerebrospinal fluid refers to placing a drainage tube into the cerebral ventricle or the lumbar spinal canal and continuously draining the cerebrospinal fluid. Firstly, it can reduce intracranial pressure. Secondly, it can promote the discharge of inflammatory cerebrospinal fluid or bloody cerebrospinal fluid, achieve the effect of cleaning cerebrospinal fluid, assist in treating ventricular inflammation, and prevent the formation of hydrocephalus caused by fibrous adhesions. The most important thing in continuous external drainage of cerebrospinal fluid is how to control the drainage speed of cerebrospinal fluid. If the speed is too fast, it will lead to over-drainage and cause acute brain hernia, endangering life. If the speed is too slow, there will be poor drainage. Eventually, due to the small inner diameter of the drainage tube itself, it is extremely easy to cause tube blockage, and finally lead to or further exacerbate the occurrence of intracranial infection.

[0003] The prior art can adopt a craniocerebral pressure monitoring and adjustment device to regulate and monitor the intracranial pressure of patients during the process of external drainage. The device mainly includes a scale and a drainage drip bottle. A sliding groove and a sliding structure are arranged on the scale, and the drainage drip bottle is fixed on the sliding structure. The drainage drip bottle is driven by the sliding structure to slide up and down in the sliding groove. Thus, the drainage speed can be controlled by adjusting the hanging height of the drainage drip bottle, and further the function of regulating intracranial pressure can be achieved. In the existing craniocerebral pressure monitoring and adjustment device, how to realize the sliding and fixing of the sliding structure is a key problem. The existing sliding structures are usually relatively complex, have poor operation convenience, and high manufacturing costs. For example, in the patent CN218793291U, a number of nuts are opened at the bottom of the sliding groove provided on the surface of the scale. When the drainage drip bottle moves to each position, one nut needs to be loosened, and the sliding structure is locked with another nut corresponding to the target position. The device is complex, costly, and has cumbersome operation. For example, in the patent CN102526817B, a locking knob and an adjusting slide can be used to realize the height adjustment of the drainage drip bottle, but this product needs to set the scale on a support plate, and a sliding groove is formed between the scale and the support plate, resulting in a larger thickness of the whole device, higher manufacturing costs, and inconvenience for medical staff to use. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide an external drainage device for facilitating the adjustment of the height of a drainage drip bottle, which has a simple structure, convenient operation, and low manufacturing cost.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] Provided is an external drainage device facilitating the adjustment of the height of a drainage drip bottle, including a sliding structure, a scale plate, and a drainage drip bottle. The drainage drip bottle is installed on the sliding structure, and the sliding structure is slidably connected to the scale plate. The sliding structure includes a first sliding member, a second sliding member respectively disposed on the front and back sides of the scale plate, and an adjusting member for adjusting the distance between the first sliding member and the second sliding member.

[0007] For the drainage device facilitating the adjustment of the height of the drainage drip bottle of the present utility model, the first sliding member and the second sliding member are both slidably connected to the scale plate to realize the adjustment of the height of the drainage drip bottle relative to the scale plate. The adjustment of the distance between the first sliding member and the second sliding member by the adjusting member realizes the sliding and fixing of the sliding structure. The sliding structure of the present utility model only includes three structures, namely the first sliding member, the second sliding member, and the adjusting member, with a simple structure and low manufacturing cost; the sliding and fixing of the sliding structure are realized by adjusting the distance between the first sliding member and the second sliding member by the adjusting member, and the operation is simple.

[0008] Further, the adjusting member includes an operation part and a threaded part connected. The first sliding member is provided with a through hole, and the second sliding member is provided with a threaded hole. The threaded part passes through the through hole and is threadedly connected to the threaded hole. The adjusting member and the second sliding member form a lead screw-nut transmission structure, converting the rotational motion of the adjusting member into the linear movement of the second sliding member, thereby changing the distance between the first sliding member and the second sliding member, and thus realizing the sliding and fixing of the sliding structure.

[0009] Further, the adjusting member further includes symmetrically arranged first and second legs and symmetrically arranged first and second bulges. The first leg is disposed between the threaded part and the first bulge, the second leg is disposed between the threaded part and the second bulge, the diameters of the first leg and the second leg are smaller than the diameters of the through hole and the threaded hole, and the diameters of the first bulge and the second bulge are larger than the diameters of the through hole and the threaded hole. There is a gap between the first leg and the second leg. Squeezing the first leg and the second leg makes the first leg and the second leg approach each other, thereby realizing the rapid installation of the adjusting member. Due to the arrangement of the first bulge and the second bulge, even if the adjusting member is loosened, the second sliding member will not fall off.

[0010] Further, a first frustum is machined on one side of the first sliding member close to the operation part, and second frustums are machined on both opposite side surfaces of the second sliding member. The setting of the first frustum and the second frustum can improve the connection strength at the joints of the adjusting member and the first sliding member and the second sliding member.

[0011] Furthermore, the scale plate is provided with a first sliding groove and a second sliding groove which are arranged in parallel. The first sliding member is slidably connected to the first sliding groove, and the second sliding member is slidably connected to the second sliding groove. The sliding structure of the present utility model has multiple sliding designs at the same time, which can ensure the stable sliding of the sliding structure.

[0012] Furthermore, the first sliding groove and the second sliding groove are communicated, and the width of the second sliding groove is greater than that of the first sliding groove. The first sliding groove is located in front of the second sliding groove. The first sliding member is connected to the drainage drip bottle and bears a relatively heavy weight. The design of the front-narrow and rear-wide slot helps to improve the stability of the sliding structure sliding relative to the scale plate.

[0013] Furthermore, the first sliding member includes a connecting plate and a limiting structure that abuts against the second sliding member to limit the rotation of the second sliding member. The limiting structure is arranged on the connecting plate and is slidably connected to the first sliding groove. When rotating and adjusting the relative distance between the first sliding member and the second sliding member, the limiting structure can prevent the second sliding member from rotating together with the rotation of the adjusting member.

[0014] Furthermore, the limiting structure includes a first stop block and a second stop block which are arranged in parallel. An installation groove for cooperating with the second sliding member is formed between the first stop block and the second stop block, and the axial direction of the installation groove intersects with the axial direction of the first sliding groove. The first stop block and the second stop block can not only play a role in stopping and limiting, but also serve as sliding components of the first sliding member.

[0015] Furthermore, the axial direction of the installation groove is perpendicular to the axial direction of the first sliding groove. When the axial direction of the installation groove is perpendicular to the axial direction of the first sliding groove, the limiting effect of the first stop block and the second stop block on the rotation of the second sliding member is better.

[0016] Furthermore, a hook-shaped part for hanging the liquid collection bag is provided at the bottom of the scale plate. The setting of the hook-shaped part facilitates the quick and stable hanging of the liquid collection bag.

[0017] Furthermore, scale marks are provided on the front surface of the scale plate, and an indicating block is provided on at least one side of the first sliding member. The indicating block is located on the front surface of the scale plate, and the indicating block and the scale marks cooperate with each other to read the intracranial pressure.

[0018] Furthermore, the sliding structure further includes a clamping assembly for clamping the drainage drip bottle and a positioning block arranged above the clamping assembly. Both the clamping assembly and the positioning block are arranged on the first sliding member, and the top surface of the drainage drip bottle abuts against the positioning block. The positioning block limits the placement height of the drainage drip bottle, which helps to simplify the reading operation and reduce the reading error.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] The drainage device of the present utility model that is convenient for adjusting the height of the drainage drip bottle consists of a sliding structure composed of a first sliding member, a second sliding member, and an adjusting member. Its structure is simple, the manufacturing cost is low, and it will not increase the thickness of the entire position adjusting device; by adjusting the distance between the first sliding member and the second sliding member through the adjusting member, the sliding and fixing of the sliding structure are realized, which is convenient for medical staff to adjust the height of the drainage drip bottle.

[0029] Embodiment 1

[0030] This embodiment is the first embodiment of the drainage device for facilitating the adjustment of the height of the drainage drip bottle 300 of the present utility model, including a sliding structure 100, a scale plate 200, and a drainage drip bottle 300, as Figure 5 shown. The drainage drip bottle 300 is installed on the sliding structure 100, and the sliding structure 100 is slidably connected to the scale plate 200; the sliding structure 100 includes a first sliding member 110, a second sliding member 120 respectively arranged on the front and back sides of the scale plate 200, and an adjusting member 130 for adjusting the distance between the first sliding member 110 and the second sliding member 120, as Figures 1 to 2 shown.

[0031] In this embodiment, the sliding connection between the sliding structure 100 and the scale plate 200 is realized by both the first sliding member 110 and the second sliding member 120 being slidably connected to the scale plate 200. The height adjustment of the drainage drip bottle 300 relative to the scale plate 200 is realized by the sliding between the sliding structure 100 and the scale plate 200. The sliding and fixing of the sliding structure 100 are realized by adjusting the distance between the first sliding member 110 and the second sliding member 120 by the adjusting member 130, that is, the fixing of the height of the drainage drip bottle 300 is realized.

[0032] In this embodiment, the adjusting member 130 includes an operating portion 131 and a threaded portion 132 which are connected and arranged. The first sliding member 110 is provided with a through hole 111, and the second sliding member 120 is provided with a threaded hole 121. The threaded portion 132 passes through the through hole 111 and is threadedly connected to the threaded hole 121. The adjusting member 130 and the second sliding member 120 form a lead screw-nut transmission structure, which converts the rotational motion of the adjusting member 130 into the linear movement of the second sliding member 120, thereby changing the distance between the first sliding member 110 and the second sliding member 120, and thus realizing the sliding and fixing of the sliding structure 100. For the lead screw-nut structure, when the threaded portion 132 is rotated by the operating portion 131, if no limit is imposed on the threaded portion 132, the second sliding member 120 will rotate together with the threaded portion 132 and cannot move linearly smoothly. In this embodiment, in order to smoothly convert the rotation of the operating portion 131 into the linear movement of the second sliding member 120, in this embodiment, the second sliding member 120 can be manually limited during the adjustment operation, or a limiting structure 150 can be provided to limit the rotation of the second sliding member 120. This embodiment does not make specific limitations here. For the convenience of rotation operation, the operating portion 131 of this embodiment is an operating knob provided with a plurality of convex portions along the circumferential direction.

[0033] In order to improve the connection stability between the first sliding member 110 and the second sliding member 120, in this embodiment, the adjusting member 130 further includes a first leg 133 and a second leg 134 which are symmetrically arranged and a first enlarged portion 135 and a second enlarged portion 136 which are symmetrically arranged. The first leg 133 is arranged between the threaded portion 132 and the first enlarged portion 135, and the second leg 134 is arranged between the threaded portion 132 and the second enlarged portion 136. The diameters of the first leg 133 and the second leg 134 are smaller than the diameters of the through hole 111 and the threaded hole 121, and the diameters of the first enlarged portion 135 and the second enlarged portion 136 are larger than the diameters of the through hole 111 and the threaded hole 121, as Figure 1 shown. There is a gap between the first leg 133 and the second leg 134. By squeezing the first leg 133 and the second leg 134, the first leg 133 and the second leg 134 are made to approach each other, thereby realizing the rapid installation of the adjusting member 130. And due to the arrangement of the first enlarged portion 135 and the second enlarged portion 136, even if the adjusting member 130 is loosened, the second sliding member 120 will not fall off. Among them, the gap between the first leg 133 and the second leg 134 is set such that: when the first leg 133 is in contact with the second leg 134 by extrusion, the first enlarged portion 135 and the second enlarged portion 136 are in contact and the first enlarged portion 135 and the second enlarged portion 136 can pass through the through hole 111 and the threaded hole 121.

[0034] To ensure the structural strength of the through hole 111 and the screw hole 121 and to avoid adverse effects on the structural strength caused by the wear of the adjusting member 130 on the first sliding member 110 and / or the second sliding member 120 during the rotation operation, in this embodiment, a first frustum 112 is machined on one side of the first sliding member 110 close to the operating portion 131, and second frustums 122 are machined on two opposite side surfaces of the second sliding member 120.

[0035] When implementing this embodiment, the first sliding member 110 and the second sliding member 120 are respectively placed on both sides of the scale plate 200, the through hole 111 of the first sliding member 110 and the screw hole 121 of the second sliding member 120 are aligned, the first leg 133 and the second leg 134 are squeezed, the adjusting member 130 is passed through the through hole 111 and the screw hole 121, and the adjusting member 130 is rotated. Under the action of the threaded portion 132 of the adjusting member 130 and the screw hole 121, the second sliding member 120 approaches the first sliding member 110 to reduce the distance between the first sliding member 110 and the second sliding member 120, thereby fastening the sliding structure 100 to the scale plate 200; when the position of the sliding structure 100 needs to be adjusted, the adjusting member 130 is rotated in the reverse direction. Under the action of the threaded portion 132 of the adjusting member 130 and the screw hole 121, the second sliding member 120 moves away from the first sliding member 110 to increase the distance between the first sliding member 110 and the second sliding member 120 until the sliding structure 100 can slide relative to the scale plate 200; during the sliding process, since the diameters of the first enlarged portion 135 and the second enlarged portion 136 are larger than the diameters of the through hole 111 and the screw hole 121, the second sliding member 120 will not fall off; when the first sliding member 110 slides to the required height, the adjusting member 130 is rotated. Under the action of the threaded portion 132 of the adjusting member 130 and the screw hole 121, the second sliding member 120 approaches the first sliding member 110 to reduce the distance between the first sliding member 110 and the second sliding member 120, thereby fastening the sliding structure 100 to the scale plate 200.

[0036] The drainage device in this embodiment that is convenient for adjusting the height of the drainage drip bottle 300 can realize the sliding and fixing of the sliding structure 100 by rotating the adjusting member 130 to adjust the distance between the first sliding member 110 and the second sliding member 120, and the operation is simple; through the structural setting of the adjusting member 130, the rapid installation of the adjusting member 130 can be realized, and even when the adjusting member 130 is loosened, the second sliding member 120 will not fall off, effectively ensuring the structural stability of the overall device.

[0037] Embodiment Two

[0038] This embodiment is a second embodiment of the drainage device of the utility model for facilitating adjustment of the height of the drainage dropper bottle 300. This embodiment is similar to the first embodiment, except that, in this embodiment, the scale plate 200 is provided with a first slide groove 240 and a second slide groove 230 arranged in parallel, the first sliding member 110 is slidably connected to the first slide groove 240, and the second sliding member 120 is slidably connected to the second slide groove 230. Figure 3 、 Figure 4 As shown, the two sliding designs can ensure that the sliding structure 100 slides stably.

[0039] The first chute 240 is connected to the second chute 230, and the width of the second chute 230 is greater than that of the first chute 240. The first chute 240 is located in front of the second chute 230. The first sliding member 110 is connected to the drainage dropper 300 and bears a heavy weight. The slot design with a narrow front and a wide rear helps improve the stability of the sliding structure 100 relative to the scale plate 200.

[0040] Specifically, the first and second slide grooves 240, 230 are stepped holes formed in the scale plate 200. A first slide rail 210 is formed between the first and second slide grooves 240, 230. The second slide groove 230 is formed between two sets of second slide rails 220, which are located on the back of the scale plate 200. After the first and second sliders 110, 120 are connected, a third slide groove 140 is formed between the first and second sliders 110, 120. The first and second sliders 110, 120 are both bilaterally symmetrical, forming two sets of the third slide grooves 140 on the left and right sides of the first and second sliders 110, 120, thereby improving the sliding stability of the sliding structure 100. In this embodiment, the width of the second slider 120 is equal to or slightly smaller than the width of the first slider 110, ensuring that the first slide groove 240 has a regular shape and the product has a compact structure.

[0041] In addition, the first sliding member 110 includes a connecting plate and a limiting structure 150 that abuts against the second sliding member 120 to limit the rotation of the second sliding member 120. The limiting structure 150 is disposed on the connecting plate and is slidably connected to the first sliding groove 240. In addition to serving as a sliding component of the first sliding member 110 and being slidably connected to the first sliding groove 240, the limiting structure 150 can also prevent the second sliding member 120 from rotating along with the adjustment member 130 when the relative distance between the first sliding member 110 and the second sliding member 120 is adjusted by rotation.

[0042] Specifically, the limiting structure 150 includes a first stop block 151 and a second stop block 152 arranged in parallel. An installation groove 153 for cooperating with the second sliding member 120 is formed between the first stop block 151 and the second stop block 152. The axial direction of the installation groove 153 intersects with the axial direction of the first chute 240. When the axial direction of the installation groove 153 is perpendicular to the axial direction of the first chute 240, the limiting effect of the first stop block 151 and the second stop block 152 on the rotation of the second sliding member 120 is the best. In this embodiment, the first stop block 151 and the second stop block 152 can not only play a role in stopping and limiting, but also serve as sliding components of the first sliding member 110, such as Figure 4 shown. Specifically, in this embodiment, the first stop block 151, the second stop block 152 and the connecting plate are of an integrally formed structure. The first stop block 151 is a plate-like structure, and the second stop block 152 is a body-like structure. To reduce the overall mass of the product, the second stop block 152 can also be designed as a frame-like structure. The first stop block 151 and the second stop block 152 have the same width and thickness. The second sliding member 120 is a plate-like structure and is placed between the first stop block 151 and the second stop block 152. In this way, the position of the second sliding member 120 is restricted in multiple directions.

[0043] When implementing this embodiment, the first sliding member 110 and the second sliding member 120 are respectively placed on both sides of the first slide rail 210. The first stop block 151 and the second stop block 152 are placed in the first chute 240. The second sliding member 120 slides in the second chute 230. The adjusting member 130 is rotated. Under the action of the threaded portion 132 of the adjusting member 130 and the screw hole 121 and under the limiting action of the first stop block 151 and the second stop block 152 on the second sliding member 120, the second sliding member 120 approaches the first sliding member 110 to reduce the distance between the first sliding member 110 and the second sliding member 120, thereby fastening the sliding structure 100 to the scale plate 200, that is, fixing the position of the drainage drip bottle 300. When it is necessary to adjust the position of the sliding structure 100, the adjusting member 130 is rotated in the reverse direction. Under the action of the threaded portion 132 of the adjusting member 130 and the screw hole 121 and under the limiting action of the first stop block 151 and the second stop block 152 on the second sliding member 120, the second sliding member 120 moves away from the first sliding member 110 to increase the distance between the first sliding member 110 and the second sliding member 120 until the thickness of the first chute 240 is greater than the thickness of the first slide rail 210, and the sliding structure 100 can slide relative to the scale plate 200. During the sliding process, the first slide rail 210 is slidably connected to the third chute 140, the first stop block 151 and the second stop block 152 are slidably connected to the first chute 240, and the second sliding member 120 is slidably connected to the second chute 230. Multiple slides can effectively improve the sliding stability of the sliding structure 100 relative to the scale plate 200.

[0044] Embodiment III

[0045] This embodiment is the third embodiment of the drainage device for facilitating the adjustment of the height of the drainage drip bottle 300 of the present utility model. This embodiment is similar to Embodiment I, except that scale marks are provided on the front surface of the scale plate 200, and indicating blocks 115 are provided on both sides of the first sliding member 110. The indicating blocks 115 are located on the front surface of the scale plate 200, and the indicating blocks 115 cooperate with the scale marks to read the intracranial pressure.

[0046] The sliding structure 100 further includes a clamping assembly 113 for clamping the drainage drip bottle 300 and a positioning block 114 provided above the clamping assembly 113. Both the clamping assembly 113 and the positioning block 114 are provided on the first sliding member 110, and the top surface of the drainage drip bottle 300 abuts against the positioning block 114. The positioning block 114 limits the height of the drainage drip bottle 300, which helps to simplify the reading operation and reduce the reading error, as Figure 2 shown.

[0047] In order to hang the liquid collection bag conveniently and stably, a hook-shaped portion 250 for hanging the liquid collection bag is provided at the bottom of the scale plate 200 in this embodiment. In this embodiment, the hook-shaped portion 250 is used to hang the liquid collection bag. On the one hand, it is easy to hang the operation, and on the other hand, the hanging is stable and the liquid collection bag can be effectively prevented from detaching from the hook-shaped portion 250. During use, the liquid collection bag is hung on the hook-shaped portion 250, that is, at the bottom of the scale plate 200, and will not move with the sliding of the drainage drip bottle 300. The operation is simple, and the manufacturing cost and manufacturing difficulty are low.

[0048] When implementing this embodiment, first install the drainage drip bottle 300 through the clamping assembly 113, position the drainage drip bottle 300 through the positioning block 114, hang the liquid collection bag at the bottom of the scale plate 200, and drive the drainage drip bottle 300 to move by sliding the sliding structure 100 on the scale to adjust the height of the drainage drip bottle 300 to control the drainage speed. When the liquid flow rate at the liquid inlet of the drainage drip bottle 300 approaches 0, the scale mark pointed to by the indicating block 115 is the intracranial pressure of the patient at this time.

[0049] In the specific content of the above specific implementation manner, the technical features can be combined arbitrarily without contradiction. For the sake of concise description, not all possible combinations of the above technical features are described. However, as long as the combinations of these technical features do not exist in contradiction, they should all be considered to be within the scope described in this specification.
