A newborn's external ventricular drainage device

Abstract

The present invention provides a newborn's ventricular external drainage device, belonging to the technical field of ventricular external drainage. By installing an external drainage bottle on a suspender, finding the patient's wound position according to a leveling component and moving the drainage bottle to a position equal to the patient's wound, the suspender drives the drainage bottle to move to a position 10-15 cm higher than the patient's wound position through a lifter, so that the patient's intracranial pressure is balanced, and the drainage fluid flow rate is balanced. The liquid level detector is located at the bottom of the drainage bottle and rises at a certain rate, and is used to detect the liquid level height in the drainage bottle. When the liquid level is too high, it indicates that the drainage rate is too fast, and the drainage bottle is raised by the lifter to reduce the drainage rate; when the detected liquid level is too low, the drainage bottle is lowered to increase the drainage rate. The device can automatically adjust the height of the drainage bottle and change the flow rate according to the change of the liquid level in the patient's drainage bottle, which greatly improves the convenience of use and reduces the workload of medical staff.

Description

Technical Field

[0001] The present invention relates to the technical field of extracerebral ventricular drainage, in particular to an extracerebral ventricular drainage device for newborns. Background Art

[0002] Purulent meningitis is an inflammation of the meninges caused by purulent bacteria (it can also be caused by other pathogens such as viruses and fungi). It usually involves acute purulent inflammation of the meninges and may also affect the brain parenchyma. The condition is particularly common in infants and children. In severe cases of purulent meningitis, external ventricular drainage surgery is required. External ventricular drainage is a procedure that involves puncturing the lateral ventricle through a burr hole or cone hole in the skull, placing a drainage tube, and draining cerebrospinal fluid to the outside of the body, thereby reducing intracranial pressure, alleviating cerebral edema, and improving blood circulation and metabolism of brain tissue, providing favorable conditions for subsequent anti-inflammatory treatment.

[0003] In the prior art, the postoperative nursing stage of extraventricular drainage is relatively complicated. Doctors need to regularly check the intracranial pressure of patients and manually adjust the height of the drainage bottle according to the amount of drainage fluid output to change the flow rate of the drainage fluid. Through searching, it is found that a kind of extracerebral drainage device with flow limiting and pressure control function disclosed by Chinese Patent Publication No. CN216986032U can accurately adjust the position height of the "U" bend of the drainage tube through a soft ruler and a rope buckle, and can adjust the drainage pressure of the patient's intracranial cerebrospinal fluid, control the drainage of the patient's cerebrospinal fluid, measure and adjust the intracranial pressure, and prevent the patient's intracranial pressure from being too small or too large to cause secondary injury. However, the above device still does not change the manual adjustment, so that doctors need to adjust it repeatedly, which is relatively cumbersome. In the neonatal stage, children are prone to crying, which causes the intracranial pressure to rise too fast and the amount of drainage fluid to increase. Doctors need to clamp the drainage fluid, and it takes a while for doctors to rush from the department to the bedside, which is easy to bring danger to newborns. And newborns are prone to pulling the drainage tube, causing the drainage tube to fall off, resulting in accidental risks.

[0004] To this end, we propose a neonatal ventricular external drainage device to solve the problems of difficulty in regulating the drainage fluid output of neonatal intracranial pressure and easy detachment of the drainage tube in the prior art. Summary of the invention

The upper ends of the leveling component 2 are connected to the lifting component 3 and the locking component 4 respectively. The leveling component 2 is used to locate the surgical wound position of the patient and adjust the lifting component 3 to the same height.

[0059] The lifting assembly 3 is located at the side of the supporting assembly 1. The lifting assembly 3 includes a lifter 30, a hanger 31, and a liquid level detector 32. The hanger 31 is used to fix the external drainage bottle. The lifter 30 is connected to the hanger 31 and is used to control the lifting and lowering of the hanger 31 and the external drainage bottle. The liquid level detector 32 is installed inside the hanger 31 and can slide up and down, and is used to detect the liquid level area range of the drainage fluid in the external drainage bottle.

[0060] The locking component 4 is detachably connected to the top of the leveling component 2 and is used to lock the external drainage tube interface to prevent it from falling off;

[0061] The control display 5 is installed at the bottom of the lifter 30 and is used to control the operation of the leveling assembly 2 and the lifting assembly 3 and display detection data.

The height of the suspender 31 is changed by the lifter 30, so that the suspender 31 drives the drainage bottle to move to a position 10-15cm higher than the patient's wound position, so that the patient's intracranial pressure is kept balanced and the drainage fluid flow rate is guided to be balanced. The liquid level detector 32 is located at the bottom of the drainage bottle and rises at a certain rate, which is used to detect the liquid level height in the drainage bottle. When the liquid level is too high, it indicates that the drainage rate is too fast. The drainage bottle is raised by the lifter 30 to reduce the drainage rate; when the detected liquid level is too low, the drainage bottle is lowered to increase the drainage rate. The device can automatically adjust the height of the drainage bottle and change the flow rate according to the change of the liquid level in the patient's drainage bottle, which greatly improves the convenience of use and reduces the workload of medical staff.

[0063] In one embodiment, the leveling component 2 includes an electric telescopic rod 20, the upper half of the support component 1 is set as a hollow structure and the electric telescopic rod 20 is located at the bottom of the hollow structure, and the top of the electric telescopic rod 20 is connected to a sliding block 21 that can move up and down along the hollow part of the support component 1, and both ends of the sliding block 21 extend outward and respectively penetrate the two end side walls of the support component 1, and the outer surface of the support component 1 is sleeved with a swivel 22, and the swivel 22 is rotatably connected to the two extensions of the sliding block 21, and the outer surface of the swivel 22 is connected to a number of evenly distributed infrared laser lights 23, and the infrared laser lights 23 are used to locate the patient's wound position, and one side of the swivel 22 is connected to a beam 24, and the two ends of the beam 24 are respectively connected to the lifting component 3 and the locking component 4.

[0064] The swivel ring 22 can rotate around the extension of the sliding block 21 to adjust the horizontal angles of the lifting assembly 3 and the locking assembly 4. At the same time, it can also change the irradiation angle of the infrared laser light 23 to make the position of the patient irradiated more accurate.

[0065] When in use, turn on all the infrared laser lights 23, start the electric telescopic rod 20, the electric telescopic rod 20 pushes the sliding block 21 to gradually rise and fall, the sliding block 21 drives the rotating ring 22 and the infrared laser light 23 to rise and fall, the infrared laser light 23 forms an irradiation point on the patient, the operator observes the relative height of the irradiation point from the wound, and finally closes the electric telescopic rod 20 within the error range of ±5cm, so that the sliding block 21 drives the lifting assembly 3 to move to a position at the same height as the patient's wound through the rotating ring 22 and the crossbeam 24.

[0066] It should be noted that the driving member for driving the sliding block 21 to slide up and down is not limited to the electric telescopic rod 20 in the text, and can be any other existing component that can move the sliding block 21 up and down by pneumatic, hydraulic or electric means.

[0067] In one embodiment, the lifter 30 includes a U-shaped bracket 301, the bottom of the U-shaped bracket 301 is connected to a motor 302, the output end of the motor 302 is connected to a screw 303, the two ends of the screw 303 are respectively rotatably connected to the inner top wall and the inner bottom wall of the U-shaped bracket 301, the outer surface of the screw 303 is threadedly connected to a threaded ring 304, the U-shaped bracket 301 is located on the opposite side of the screw 303 and is connected to a vertical sliding rod 305, the outer surface of the sliding rod 305 is slidably connected to a circular ring 306, the suspender 31 is located between the threaded ring 304 and the circular ring 306, and the facing sides of the threaded ring 304 and the circular ring 306 are both extended outward with a cross bar 307 for connecting the suspender 31.

[0068] After the leveling component 2 moves the lifting component 3 to the same height as the patient's wound, the motor 1 302 is started, the motor 1 302 drives the screw 303 to rotate, the screw 303 drives the threaded ring 304 to rise, the threaded ring 304 cooperates with the circular ring 306 to drive the suspender 31 to rise by 10-15cm, so that the patient's intracranial pressure and the drainage rate of the drainage fluid are the same. The device can automatically adjust the height of the drainage bottle, ensure that the drainage bottle is at a height of 10-15cm above the patient's wound, ensure that the intracranial pressure is stable, and the drainage rate is normal.

[0069] In one embodiment, the U-shaped bracket 301 is connected to a vertical scale 308 on the other side of the screw rod 303 , and a positioning frame 309 is sleeved on the outer surface of the scale 308 . The side of the positioning frame 309 is connected to the threaded ring 304 for moving up and down with the threaded ring 304 .

[0070] The threaded ring 304 drives the positioning frame 309 to rise and fall on the scale 308, so that the operator can observe the height relative to the patient's wound through the positioning frame 309 and the scale 308 and make timely adjustments.

[0071] In one embodiment, the hanger 31 includes a fixing frame 310, the inner top of which is connected to a hook 311, the bottom of the fixing frame 310 is connected to a ring 312 and a clamp 313 via a connecting rod, and the clamp 313 is located below the ring 312 and is used to clamp the drainage tube.

[0072] The hook 311 is used to hang the drainage bottle, and the ring 312 is used to support the bottom of the drainage bottle to prevent the drainage bottle from falling.

[0073] In one embodiment, the clamp 313 includes a toothless vascular clamp 3130 , and an electric push rod 3131 is connected between two clamp arms of the toothless vascular clamp 3130 . The electric push rod 3131 is used to control the clamping and opening of the toothless vascular clamp 3130 .

[0074] The toothless vascular clamp 3130 is opened and closed by extending and retracting the electric push rod 3131, thereby completing the clamping and opening of the drainage tube.

[0075] In one embodiment, the liquid level detector 32 includes a driving part 320 , a front end of the driving part 320 is connected to a manual regulator 321 , and the manual regulator 321 is connected to two detection parts 322 ;

[0076] The driving unit 320 includes a second motor, and the second motor is connected to a conveyor belt structure through a gear set;

[0077] The gear set is two gears meshing with each other, which are used to compensate for the distance between the second motor and the conveyor belt. The second motor is used to control the forward and reverse rotation of the conveyor belt.

[0078] The manual regulator 321 includes a guide rail connected to the front end of the conveyor belt, the inner side walls of the front and rear ends of the guide rail are slidably connected with racks, the middle part of the left end of the guide rail is rotatably connected with a knob, and the right end of the knob passes through the guide rail and is connected with a latch tooth, which matches the rack;

[0079] In actual operation, the operator can turn the knob, the knob drives the latch gear to rotate, and the latch gear drives the two racks to move toward or relative to each other. A latch is provided on the side of the knob to lock the knob to prevent the knob from rotating.

[0080] The two detection parts 322 each include a C-shaped support bar 3220 , and the inner side walls at both ends of each C-shaped support bar 3220 are respectively connected to a sensor transmitter 3221 and a receiver 3222 , and each C-shaped support bar 3220 is connected to a rack.

[0081] In actual operation, the sensor transmitter 3221 emits a light signal, and the receiver 3222 at the other end of the drainage bottle receives the signal, so as to determine whether there is drainage fluid at the horizontal position. When the liquid level of the drainage bottle is between the two detection parts 322, the lower detection part 322 cannot receive the signal to detect the presence of liquid level, and the upper detection part 322 can receive the signal to detect the absence of liquid level. It should be noted that the drainage bottle used is preferably made of transparent material to facilitate the sensor to detect the liquid level and the naked eye to observe the liquid level.

[0082] When in use, according to the model and specification of the drainage bottle, the two racks drive the two detection parts 322 to move toward or relative to each other, change the distance between the two detection parts 322, and adjust the detection range of the liquid level in the drainage bottle. After drainage, start the second motor, the second motor conveyor belt rotates, and the conveyor belt drives the two detection parts 322 to rise through the manual adjustment part 321, so that the detection parts 322 rise together with the liquid level in the drainage bottle. If the liquid level is always within the detection range, it is within the normal range. When the liquid level exceeds (both detection parts 322 cannot receive signals) or is lower than (both detection parts 322 can receive signals) the detection range of the two detection parts 322, a signal is issued and the height of the drainage bottle is adjusted accordingly.

The liquid level detector 32 is located at the bottom of the drainage bottle and rises at a certain rate. It is used to detect the liquid level height in the drainage bottle. When the liquid level is higher than the detection range, it indicates that the drainage rate is too fast. The drainage bottle is raised by the lifter 30 to reduce the drainage rate; when the detected liquid level is too low, the drainage bottle is lowered to increase the drainage rate.

[0091] In summary, the neonatal external ventricular drainage device disclosed in the present invention can automatically adjust the height of the drainage bottle, and according to the changes in the liquid level in the patient's drainage bottle, automatically adjust the height of the drainage bottle, change the flow rate, and maintain the intracranial pressure of the neonatal patient stable, which greatly improves the convenience of use and reduces the workload of medical staff.

[0092] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
