Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a drainage tube support device. Background Art

[0002] The lumbar cistern drainage refers to a method of placing one end of a drainage tube into the lumbar cistern and continuously draining cerebrospinal fluid to the outside at the other end. The function of the lumbar cistern drainage is to reduce intracranial pressure and then reduce the amount of cerebrospinal fluid after drainage, which is a simple and effective surgical method for treating increased intracranial pressure.

[0003] Currently, when draining a patient, an infusion stand is used in combination to support the drainage tube. However, since the drainage tube is relatively long, bent parts will inevitably be formed. For example, after both ends of the drainage tube are fixed, other parts of the drainage tube are in a natural hanging state, and a bend will be formed at the bottom. If the curvature of the bottom bend is large, it is easy to occur the phenomenon of folding (that is, the inner walls of the drainage tube approach each other), resulting in the abnormal flow of the medium in the drainage tube. Therefore, medical staff will wind the drainage tube around the infusion stand. However, due to the gravity of the drainage tube and the fact that it cannot be wound too tightly (if it is wound too tightly, the phenomenon that the inner walls of the drainage tube approach each other will still occur), the drainage tube will fall due to its own weight, and the folding phenomenon still cannot be effectively solved.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] The embodiment of the present invention provides a drainage tube support device for eliminating the phenomenon of folding of the drooping part of the drainage tube and realizing the support of the drainage tube to ensure that during the drainage process of the patient, the phenomenon that the drainage tube is blocked due to bending is avoided, as Figure 7 shown, which is an application scenario diagram of the drainage tube support device.

[0030] As Figure 1 and Figure 2 shown, the embodiment of the present invention provides a drainage tube support device, including a first support frame 1 and a second support frame 2; the first support frame 1 is rotatably connected to the second support frame 2 through a locking piece 3.

[0031] One end of the first support frame 1 away from the locking piece 3 is rotatably connected with a first clamping piece 4. Exemplarily, one end of the first support frame 1 away from the locking piece 3 is hinged to the first clamping piece 4; one end of the second support frame 2 away from the locking piece 3 is rotatably connected with a second clamping piece 5. Exemplarily, one end of the second support frame 2 away from the locking piece 3 is hinged to the second clamping piece 5; both the first clamping piece 4 and the second clamping piece 5 are used for clamping the drainage tube. The locking piece 3 is used to lock the positions of the first support frame 1 and the second support frame 2, and when the locking piece 3 is triggered to the unlocking state, the first support frame 1 and the second support frame 2 can rotate relative to each other.

[0032] In the embodiment of the present utility model, the first clamping member 4 and the second clamping member 5 are used to clamp the drainage tube respectively, so that the drainage tube between the first clamping member 4 and the second clamping member 5 forms a U-shaped structure (defined as the drooping bottom). At the same time, the included angle between the first support frame 1 and the second support frame 2 can be adjusted according to requirements to adjust the curvature of the drooping bottom, thereby eliminating the phenomenon of folding at the drooping bottom to a certain extent and ensuring the smooth progress of the drainage work.

[0033] In one embodiment, the second clamping member 5 is connected with a fixing member 6; the fixing member 6 is fixedly connected to the infusion stand.

[0034] As Figure 3 and Figure 4 shown, the second clamping member 5 includes a first arc-shaped member 51 and a second arc-shaped member 52; the first arc-shaped member 51 is rotatably connected to the fixing member 6; the second arc-shaped member 52 is rotatably connected to the second support frame 2; the first arc-shaped member 51 and the second arc-shaped member 52 form an openable and closable cylindrical structure. An elastic member 7 is arranged between the first arc-shaped member 51 and the fixing member 6.

[0035] Based on the application environment, the fixing member 6 is used to connect the clamp, and the fixing member 6 can be fixed on the infusion stand through the clamp, so as to realize the support of the fixing member 6 and the overall drainage tube support device connected to the fixing member 6. At the same time, the arranged elastic member 7 can realize a small swing between the second support frame 2 and the fixing member 6 when the drainage tube is displaced, reducing the risk that the drainage tube cannot give way due to the pulling force.

[0036] Exemplarily, one end of the first arc-shaped member 51 is hinged to one end of the second arc-shaped member 52; a slot 511 is arranged at the end of the first arc-shaped member 51 far from the hinge; as Figure 5 shown, a plug 521 matching the slot 511 is opened at the end of the second arc-shaped member 52 far from the hinge.

[0037] During the use process, the plug 521 is disengaged from the slot 511, then the drainage tube is placed between the first arc-shaped member 51 and the second arc-shaped member 52, and then the first arc-shaped member 51 and the second arc-shaped member 52 are closed, so that the plug 521 is clamped into the slot 511 to realize connection and fixation. In this embodiment, it can also be that slots 511 are arranged at both ends of the first arc-shaped member 51, and plugs 521 are correspondingly opened at both ends of the second arc-shaped member 52. During the use process, the two plugs 521 on the second arc-shaped member 52 are respectively disengaged from the two slots 511 on the first arc-shaped member 51, then the drainage tube is placed between the first arc-shaped member 51 and the second arc-shaped member 52, and then the first arc-shaped member 51 and the second arc-shaped member 52 are closed, so that the two plugs 521 are clamped into the corresponding two slots 511 to realize connection and fixation.

[0038] To increase the frictional force between the first arc-shaped member 51 and the second arc-shaped member 52 and the drainage tube, at least one anti-slip protrusion 53 is provided on the inner wall of the first arc-shaped member 51 and / or the second arc-shaped member 52. The protrusion height of the anti-slip protrusion 53 is relatively low, as long as it satisfies that the anti-slip protrusion 53 protrudes from the inner arc surface of the first arc-shaped member 51 and / or the second arc-shaped member 52. The specific protrusion height can be selected according to requirements. Of course, the protrusion height of the anti-slip protrusion 53 cannot affect the passing capacity of the drainage tube.

[0039] In another embodiment, as Figure 6 shown, a first disc connecting member 11 is provided at one end of the first support frame 1 away from the first clamping member 4; a second disc connecting member 21 is provided at one end of the second support frame 2 away from the second clamping member 5. Exemplarily, the number of the first disc connecting members 11 is one; the number of the second disc connecting members 21 is two and they are arranged side by side; the first disc connecting member 11 is located between the two second disc connecting members 21.

[0040] A first through hole 111 is axially formed in the middle of the first disc connecting member 11 along the axis of the first disc connecting member 11; second through holes 211 are axially formed in the middle of the two second disc connecting members 21 along the axis of the second disc connecting member 21.

[0041] The locking member 3 includes a cylindrical member 31 and a first limiting member 32 connected in sequence; the cylindrical member 31 passes through the first through hole 111 and is slidably connected to the first disc connecting member 11 along the axis of the first disc connecting member 11. It should be noted that the cylindrical member 31 is only slidably connected to the first disc connecting member 11 along the axis of the first disc connecting member 11, and the cylindrical member 31 cannot rotate circumferentially around a point on the axis of the cylindrical member 31 along the first disc connecting member 11.

[0042] The cylindrical member 31 can rotate reciprocally within the second through hole 211, that is, the cylindrical member 31 can rotate circumferentially around a point on the axis of the cylindrical member 31 along the second disc connecting member 21. Under this condition, the cylindrical member 31 can of course reciprocally rotate within the second through hole 211 along the axis of the second disc connecting member 21.

[0043] The first limiting member 32 is located within the second through hole 211 and is slidably connected to the second disc connecting member 21 along the axis of the second disc connecting member 21. It should be noted that when the first limiting member 32 is located within the second through hole 211, the first limiting member 32 is only slidably connected to the second disc connecting member 21 along the axis of the second disc connecting member 21, and the first limiting member 32 cannot rotate circumferentially around a point on the axis of the first limiting member 32 along the second disc connecting member 21.

[0044] Regarding the cylindrical member 31 and the first through hole 111, if the cross-section of the cylindrical member 31 perpendicular to the axial direction of the cylindrical member 31 is a polygon, then the cross-section of the first through hole 111 along the radial direction of the first through hole 111 is a polygon with the same number of sides as the cylindrical member 31. In other words, the cross-sectional profile of the cylindrical member 31 perpendicular to the axial direction of the cylindrical member 31 is the same as the cross-sectional profile of the first through hole 111 along the radial direction of the first through hole 111.

[0045] Exemplarily, the cylindrical member 31 is a cylindrical structure; the first limiting member 32 is a gear; the first through hole 111 and the second through hole 211 are both cylindrical structures; on the inner wall of the second through hole 211, along the circumferential direction of the second through hole 211, a plurality of internal teeth matching the gear are uniformly arranged. At this time, the diameter of the second through hole 211 is greater than the diameter of the cylindrical member 31.

[0046] As Figure 6 shown, a second limiting member 311 is arranged on the outer wall of the cylindrical member 31 along the axial direction of the cylindrical member 31; a limiting groove 1111 matching the second limiting member 311 is formed on the inner wall of the first through hole 111.

[0047] The meshing of the internal teeth and the external teeth of the gear, and the cooperation between the second limiting member 311 and the limiting groove 1111 prevent the first support frame 1 and the second support frame 2 from rotating relative to each other, thereby locking the included angle between the first support frame 1 and the second support frame 2.

[0048] Push the cylindrical member 31 along the axial direction of the cylindrical member 31 towards the direction close to the second through hole 211, so that the first limiting member 32 disengages from the second through hole 211. At this time, the first support frame 1 and the second support frame 2 can rotate relative to each other. After adjusting the angle (included angle) between the first support frame 1 and the second support frame 2, place the first limiting member 32 into the second through hole 211 to fix the angle between the first support frame 1 and the second support frame 2.

[0049] Preferably, the locking member 3 further includes a pressing member 33; the pressing member 33 is fixedly connected to one end of the cylindrical member 31 away from the first limiting member 32; a spring 34 is sleeved on the outer wall of the cylindrical member 31; both ends of the spring 34 abut against the pressing member 33 and the first disc-shaped connecting member 11 respectively.

[0050] In this embodiment, the spring 34 is in a compressed state, and the spring 34 has a tendency to push the pressing member 33 away from the second through hole 211, thereby fixing the first limiting member 32 in the second through hole 211 and preventing the first limiting member 32 from falling out of the second through hole 211 during use. When it is necessary to adjust the angle between the first support frame 1 and the second support frame 2, press the pressing member 33 to further compress the spring 34 until the first limiting member 32 disengages from the second through hole 211. When the angle between the first support frame 1 and the second support frame 2 is adjusted to the required angle, release the pressing member 33. Under the pressure of the spring 34, place the first limiting member 32 in the second through hole 211 to achieve the angle fixation of the first support frame 1 and the second support frame 2.

[0051] The present invention has been described in detail above in combination with specific embodiments and exemplary examples, but these descriptions should not be construed as limiting the present invention. Those skilled in the art understand that without departing from the spirit and scope of the present invention, various equivalent substitutions, modifications or improvements can be made to the technical solutions and implementation manners of the present invention, and these all fall within the scope of the present invention. The protection scope of the present invention is subject to the appended claims.
