Description

Technical Field

[0001] This utility model relates to the field of medical device drainage rack technology, and in particular to a portable multifunctional neurosurgical drainage rack. Background Technology

[0002] After neurosurgery, drainage tubes are used to drain postoperative oozing blood. The height of the drainage tubes also needs to be adjusted using a drainage frame to meet requirements such as keeping the drainage bag 10-15 cm above the external auditory canal for ventricular drainage.

[0003] The existing drainage tube is suspended outside the hospital bed by a drainage frame. The bottom of the drainage frame is supported by outriggers. To ensure the stability of the drainage frame, the outriggers extend radially outward. However, when the drainage frame is carried and moved, the outriggers are prone to collisions with the surroundings, especially when passing through places such as ward doors. The collisions of the outriggers can also cause backlash and interference to medical staff, making it inconvenient to carry and move the drainage frame. Summary of the Invention

[0004] This embodiment relates to a portable multifunctional neurosurgical drainage frame. By switching between the support mode and the storage mode through the misalignment and alignment of the outer slot of the middle limiting plate and the lower support leg, the lower support leg can be quickly switched. After the outer slot and the lower support leg are aligned, the lower support leg rotates downward and retracts. The lower support leg and the lower support frame keep in the same direction to reduce the space occupied, making it easier to pass through doorways and other locations, and effectively avoiding bumps and interference when passing through ward doors.

[0005] In a first aspect, this disclosure provides a portable multifunctional neurosurgical drainage frame, specifically comprising: an upper support rod, a lower support frame, and a middle drainage bracket. The lower part of the upper support rod and the lower support frame are axially slidably connected, and the middle part of the upper support rod is axially vertically slidably connected to the middle drainage bracket. Both the upper and lower parts of the upper support rod are provided with inner rotating shafts that are rotatably connected through rotating shafts. The inner rotating shafts are tensioned and engaged with the inner sides of the upper and lower parts of an annular chain. The lower part of the upper support rod is screwed with a lower fixing screw.

[0006] Furthermore, the lower support frame is provided with a rotating lower support leg in a circular array at its lower part, and a middle limiting plate is provided in a circumferential direction at the lower end of the lower support frame. The middle limiting plate is provided with an outer slot in a circular array, and the upper part of the lower support frame is provided with upper threaded limiting holes in an axially spaced array.

[0007] Furthermore, the upper threaded limiting hole and the lower fixing screw are screwed together to fix the relative position between the upper support rod and the lower support frame. When the outer slot and the lower support leg are staggered, the bottom surface of the middle limiting plate and the upper part of the lower support leg are in contact, and the lower support leg remains in a horizontal state.

[0008] Furthermore, when the outer slot and the lower support leg are aligned, the lower support leg can rotate downwards, while the lower support leg remains in the same axial direction as the lower support frame.

[0009] Furthermore, a tightening screw is threaded to one side of the middle part of the central drainage bracket, a connecting pin slides through the other side of the middle part of the central drainage bracket, a lower hook is fixedly installed at the lower part of the central drainage bracket, and the lower part of the central drainage bracket is fixedly connected to the first end of the lower connecting rope.

[0010] Furthermore, one side of the annular chain is connected to the central drainage bracket via a sliding engagement with a connecting pin, and the other side of the annular chain is connected to the side counterweight frame via a sliding engagement with a connecting pin. The side counterweight frame and the central drainage bracket move in opposite directions via the annular chain.

[0011] Furthermore, the head end of the tightening screw and the upper support rod are tightly abutted together, the side counterweight frame and the upper support rod are axially and vertically slidably connected, and a lower hook is fixedly installed at the lower part of the side counterweight frame for suspending the counterweight. The gravitational potential energy of the weight at the lower part of the side counterweight frame drives the central drainage bracket on the other side to move upward through the ring chain. The lower connecting rope between the central drainage bracket and the bed body is kept taut and taut. When the bed body rises and falls, the lower connecting rope pulls the central drainage bracket and the drainage tube to move synchronously, eliminating the need for medical staff to frequently manually adjust the height of the central drainage bracket.

[0012] This utility model provides a portable multifunctional neurosurgical drainage frame, which has the following beneficial effects:

[0013] By switching between the outer slot of the middle limiting plate and the misalignment of the lower support leg, the support mode and storage mode can be quickly switched. After the outer slot and the lower support leg are aligned, the lower support leg rotates downward and retracts. The lower support leg and the lower support frame keep in the same direction to reduce the space occupied, making it easier to pass through doorways and other locations. This effectively avoids bumps and interference when passing through ward doors. With the sliding compression of the support rod and the lower support frame, it can be quickly transferred with one hand, meeting the mobility needs of ICU, emergency and other scenarios.

[0014] When the bed rises and falls, the central drainage support moves synchronously with the bed's movement, eliminating the need for frequent manual adjustments by medical staff. The central drainage support and the bed maintain a fixed distance, meeting the height requirements between the neurosurgical drainage tube and the patient. This ensures that the vertical height between the drainage bag and the patient's drainage site is always maintained at the designed value, avoiding the risk of poor drainage or backflow caused by changes in height. It also eliminates the need to adjust the height of the drainage support synchronously when the bed moves. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model proposes a portable multifunctional neurosurgical drainage frame, comprising: an upper support rod 1, a lower support frame 2, and a middle drainage bracket 3. The upper support rod 1 has inner rotating shafts 101 rotatably mounted on both its upper and lower ends via rotating shafts. The inner rotating shafts 101 are tensioned and engaged with the inner sides of the upper and lower parts of an annular chain 102. A lower fixing screw 103 is screwed onto the lower part of the upper support rod 1. The lower part of the upper support rod 1 and the lower support frame 2 are axially slidably connected. The lower part of the lower support frame 2 has rotating lower support legs 201 arranged in an annular array. A middle limiting plate 202 is rotatably mounted on the lower end of the lower support frame 2, and the middle limiting plate 202 has an outer slot 203 arranged in an annular array. The upper part of the lower support frame 2 has upper threaded limiting holes 204 arranged in an axially spaced array. The upper threaded limiting holes 204 are screwed onto the first ends of the lower fixing screws 103, fixing the upper support rod 1 and the lower support frame 2. When the outer slot 203 and the lower support leg 201 are misaligned, the bottom surface of the middle limit plate 202 and the upper part of the lower support leg 201 are in contact, and the lower support leg 201 remains in a horizontal state. The middle part of the upper support rod 1 is axially vertically slidably connected to the middle drainage bracket 3. The middle part of the middle drainage bracket 3 is threadedly connected to one side of the middle part of the middle drainage bracket 3, and the other side of the middle part of the middle drainage bracket 3 is slidably connected to the connecting pin 303. The lower part of the middle drainage bracket 3 is fixedly provided with the lower hook 302. The lower part of the middle drainage bracket 3 is fixedly connected to the first end of the lower connecting rope 304. One side of the ring chain 102 is connected to the middle drainage bracket 3 through the sliding engagement of the connecting pin 303. The other side of the ring chain 102 is connected to the side counterweight frame 305 through the sliding engagement of the connecting pin 303. The side counterweight frame 305 and the middle drainage bracket 3 move in opposite directions through the ring chain 102.

[0031] In this embodiment, when the outer slot 203 and the lower support leg 201 are aligned, the lower support leg 201 can rotate downwards. The lower support leg 201 remains in the same direction as the lower support frame 2, which facilitates storage and carrying, and effectively avoids collisions and interference when passing through the standard width of 800mm of the ward door.

[0032] In this embodiment, the head end of the tightening screw 301 and the upper support rod 1 are tightly abutted together. The side counterweight frame 305 and the upper support rod 1 are axially and vertically slidably connected. The lower part of the side counterweight frame 305 is fixedly provided with a lower hook 302 for suspending counterweights. The gravitational potential energy of the weights at the bottom of the side counterweight frame 305 drives the middle drainage bracket 3 on the other side to move upward through the ring chain 102. The lower connecting rope 304 between the middle drainage bracket 3 and the bed body is kept taut and taut. When the bed body rises and falls, the lower connecting rope 304 pulls the middle drainage bracket 3 and the drainage tube to move synchronously. There is no need for medical staff to frequently manually adjust the height of the middle drainage bracket 3. The middle drainage bracket 3 and the bed body are kept at a fixed distance to meet the height distance between the neurosurgical drainage tube and the patient.

[0033] In Example 2, based on Example 1, the upper support rod 1 is provided with a box to surround the ring chain 102, so as to avoid direct contact between external personnel and the ring chain 102, prevent external objects from getting caught in the ring chain 102 and causing jamming, and ensure the smooth movement of the ring chain 102.

[0034] The working principle of this embodiment is as follows: By switching between the misaligned alignment state of the outer slot 203 of the middle limiting plate 202 and the lower support leg 201, a rapid transition between support mode and storage mode is achieved. The middle limiting plate 202 rotates circumferentially. After the outer slot 203 and the lower support leg 201 are misaligned, the bottom surface of the middle limiting plate 202 and the upper part of the lower support leg 201 form a rigid limit, keeping the lower support leg 201 in a horizontal extended state. The lower support leg 201 supports the lower support frame 2, keeping it vertically standing beside the hospital bed. After the outer slot 203 and the lower support leg 201 are aligned, the lower support leg 201 rotates downward through the outer slot 203. The lower support leg 201 and the lower support frame 2 rotate downwards and retract, with the lower support leg 201 and the lower support frame 2 moving vertically downwards in the same direction. This reduces the space occupied by the lower support leg 201 and the lower support frame 2, making it easier to pass through doorways and other locations. It effectively avoids bumps and interference when passing through ward doors with a standard width of 800mm. With the upper support rod 1 and the lower support frame 2 having a sliding compression height adjustment range of 600-1200mm, it can be quickly transferred with one hand, meeting the mobility needs of ICU, emergency and other scenarios. At the same time, the sliding compression between the upper support rod 1 and the lower support frame 2 makes it more convenient for personnel to transfer and carry, and the height of the upper support rod 1 can be easily adjusted according to the usage status.

[0035] The central drainage support 3 suspends the drainage tube via the lower hook 302. The lower connecting rope 304 is tied to the height-adjustable bed. The side counterweight frame 305 suspends a 100g weight via the lower hook 302. The gravitational potential energy of the weight at the bottom of the side counterweight frame 305 drives the central drainage support 3 on the other side to move upward via the annular chain 102. The lower connecting rope 304 between the central drainage support 3 and the bed remains taut and taut. When the bed rises or falls, the lower connecting rope 304 pulls the central drainage support 3 and the drainage tube. The system allows for synchronized movement, eliminating the need for frequent manual adjustments to the height of the central drainage support 3 by medical staff. The central drainage support 3 and the bed maintain a fixed distance, ensuring sufficient height between the neurosurgical drainage tube and the patient. This guarantees that the vertical height between the drainage bag and the patient's drainage site is always maintained at the designed value, such as the 10-15cm required for intracranial pressure monitoring. This avoids the risk of poor drainage or backflow caused by changes in height difference, and eliminates the need to adjust the height of the drainage support simultaneously when the bed is tilted, reducing the adjustment procedures for staff.
