Description

Technical Field

[0001] The present invention relates to a drainage device, and in particular to an intracranial hydrocephalus drainage device. Background Art

[0002] Hydrocephalus drainage is a common surgical method for treating hydrocephalus. The main purpose is to drain excessive cerebrospinal fluid in the cerebral ventricle to relieve intracranial pressure and promote the recovery of brain tissue. During the drainage process of children with hydrocephalus in pediatric neurosurgery, after the operation, a sac needs to be installed or a shunt needs to be made to drain the hydrocephalus (cerebrospinal fluid). Generally, the drainage bag is hung on the head of the bed or 10-15 cm above the ear.

[0003] Because the drainage is a gravity operation, some caregivers are relatively careless and may forget to turn it off, resulting in too fast a flow rate when picked up, leading to an unstable intracranial pressure, which will have a certain impact on the growth and development of the child. Secondly, if the cerebrospinal fluid becomes infected and there are flocculent substances, there may be a situation of blocked tubes, resulting in the inability to perform normal drainage operations. Summary of the Invention

[0004] The purpose of the present invention is to provide an intracranial hydrocephalus drainage device to solve the problems presented in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: an intracranial hydrocephalus drainage device, including a support base, a placement base is fixedly connected to the upper surface of the support base, a storage barrel is placed on the placement base, a suction piston is slidably installed in the storage barrel, a connection head is fixedly connected to the upper surface of the suction piston, a drainage tube is inserted into the connection head, an electric telescopic cylinder is fixedly connected to the upper surface of the support base, a clamping joint is fixedly connected to the upper surface of the electric telescopic cylinder, a cushion column is fixedly connected to the lower surface of the suction piston, a connection buckle block is fixedly connected to the lower surface of the cushion column, a connection buckle groove is opened in the connection buckle block, and the connection buckle groove cooperates with the clamping joint.

[0006] Preferably, an avoidance groove is opened on the front surface of the placement base, a limit card slot is opened on one side of the avoidance groove, a dovetail chute is opened at the bottom of the avoidance groove, and a control host is fixedly connected to the rear surface of the support base.

[0007] Preferably, a limit convex block is fixedly connected to one side of the connection buckle block, and the limit convex block cooperates with the limit card slot.

[0008] Preferably, a vertical rod is fixedly connected to the upper surface of the placement base, a buckle is fixedly connected to the front surface of the vertical rod, and the drainage tube is clamped in the buckle.

[0009] Preferably, a scale is engraved on the outer wall of the storage barrel, and a limit angle is fixedly connected to the inner wall of the storage barrel near the lower edge.

[0010] Preferably, a dovetail slider is fixedly connected to the outer wall of the storage barrel near the lower edge, and a limiting hole is formed in the dovetail slider.

[0011] Preferably, a limiter is fixedly connected to the bottom of the placement base. A limiting groove is formed in the limiter, and a limiting pin is slidably installed in the limiting groove. The limiting pin cooperates with the limiting hole.

[0012] Preferably, a return spring is fixedly connected to the limiting groove, and the other end of the return spring is fixedly connected to the limiting pin.

[0013] Preferably, a shifting handle is fixedly connected to the limiting pin.

[0014] Preferably, a side joint is fixedly connected to the drainage tube, and a pressure sensor is inserted into the side joint.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By starting the electric telescopic cylinder, the suction piston can be driven to move downward. When the suction piston moves downward, the hydrocephalus in the patient's cranial cavity can be slowly pumped out through the drainage tube. By controlling the stroke of the electric telescopic cylinder, the suction speed and the flow rate can be controlled according to the preset values. Compared with the traditional gravity drainage, it can avoid the increase in the flow rate caused by the change of the patient's body position.

[0017] 2. By using the pressure sensor, the intracranial pressure of the patient can be measured. According to the preset intracranial threshold of the patient, the extraction of the hydrocephalus can be paused when the intracranial pressure is too low, and the extraction of the hydrocephalus can be accelerated when the intracranial pressure is too high.

[0018] 3. By driving the limiting pin to move downward with the shifting handle, the limiting pin is moved out of the limiting hole, and the restriction on the storage barrel is released. The storage barrel can be moved forward to separate the connecting buckle from the clamping joint, and then the storage barrel can be removed separately, which is convenient for later dumping and treatment of the extracted hydrocephalus.

[0025] 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 creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1-5 shown, the present invention has the following specific embodiments.

[0027] Embodiment 1

[0028] An intracranial hydrocephalus drainage device includes a support base 1, a placing base 101 is fixedly connected to the upper surface of the support base 1, a storage barrel 2 is placed on the placing base 101, a suction piston 205 is slidably installed in the storage barrel 2, a connector 210 is fixedly connected to the upper surface of the suction piston 205, a drainage pipe 5 is inserted into the connector 210, an electric telescopic cylinder 3 is fixedly connected to the upper surface of the support base 1, a card connector 301 is fixedly connected to the upper surface of the electric telescopic cylinder 3, a pad column 206 is fixedly connected to the lower surface of the suction piston 205, a connecting buckle block 207 is fixedly connected to the lower surface of the pad column 206, a connecting buckle groove 208 is formed in the connecting buckle block 207, and the connecting buckle groove 208 cooperates with the card connector 301.

[0029] In this implementation scheme, the piston column of the electric telescopic cylinder 3 is connected to the suction piston 205 through the cooperation of the connecting buckle groove 208 and the clamping joint 301. The other end of the drainage tube 5 is connected to a drainage needle or the like and communicated with the patient's cranial cavity. Then, the accumulated water in the patient's cranial cavity will be transported to the storage barrel 2 through the drainage tube 5. Starting the electric telescopic cylinder 3 can drive the suction piston 205 to move downward. The downward movement of the suction piston 205 will form a negative pressure inside the storage barrel 2, thereby actively sucking the accumulated water in the patient's cranial cavity. At the same time, by using the control module, the stroke of the electric telescopic cylinder 3 can be controlled. According to the preset setting, the suction speed and the flow rate can be controlled. Compared with the traditional gravity drainage, it can avoid the problem that the flow rate becomes faster due to the change of the patient's body position. At the same time, the active suction method can avoid the problems of blockage or slowdown of the accumulated water outflow caused by the infection of cerebrospinal fluid and the presence of floccules.

[0030] Example 2

[0031] A relief groove 106 is formed on the front surface of the placement base 101. A limit card slot 107 is formed on one side inside the relief groove 106. A dovetail chute 108 is formed on the bottom inside the relief groove 106. A control host 102 is fixedly connected to the back of the support base 1. A limit convex block 209 is fixedly connected to one side of the connecting buckle block 207. The limit convex block 209 cooperates with the limit card slot 107. A vertical rod 104 is fixedly connected to the upper surface of the placement base 101. A buckle 105 is fixedly connected to the front surface of the vertical rod 104. The drainage tube 5 is clamped in the buckle 105. A scale 201 is engraved on the outer wall of the storage barrel 2. A limit angle 202 is fixedly connected to the inner wall of the storage barrel 2 near the lower edge.

[0032] In this implementation scheme, the relief groove 106 can avoid interference between the cushion column 206, the connecting buckle block 207 and the placement base 101. The limit convex block 209 cooperates with the limit card slot 107, which can limit the angle at which the cushion column 206 is inserted, so that the opening of the connecting buckle groove 208 faces backward. Then, the storage barrel 2 slides from front to back, so that the clamping joint 301 can be inserted into the inside of the connecting buckle groove 208, thereby connecting the clamping joint 301 to the connecting buckle block 207. At this time, starting the clamping joint 301 can drive the suction piston 205 to move up and down through the connecting buckle block 207. The limit angle 202 is used to limit the suction piston 205 from moving out of the inside of the storage barrel 2. The whole storage barrel 2 is transparent, and the scale 201 can be used to intuitively understand the amount of cerebrospinal fluid extracted inside the storage barrel 2.

[0033] Example 3

[0034] A dovetail slider 203 is fixedly connected to the outer wall of the storage barrel 2 near the lower edge, and a limit hole 204 is provided in the dovetail slider 203. A limiter 4 is fixedly connected to the lower side of the base 101, and a limit groove 401 is provided in the limiter 4. A limit pin 403 is slidably installed in the limit groove 401. The limit pin 403 cooperates with the limit hole 204. A return spring 402 is fixedly connected to the limit groove 401, and the other end of the return spring 402 is fixedly connected to the limit pin 403. A shift handle 404 is fixedly connected to the limit pin 403. A bypass joint 501 is fixedly connected to the drainage tube 5, and a pressure sensor 502 is plugged into the bypass joint 501.

[0035] In this embodiment, the storage barrel 2 is connected to the control host 102 by sliding the dovetail slider 203 with the dovetail slot 108. The return spring 402 can provide a certain thrust for the limit pin 403. The limit pin 403 can be inserted into the limit hole 204 under the thrust, and then the dovetail slider 203 is fixed in the dovetail slot 108, and the storage barrel 2 is fixed on the base 101. The limit pin 403 can be driven to move by the shift handle 404, and the pressure sensor 502 can be used to The side joint 501 is clamped on the drainage tube 5, and the interior of the drainage tube 5 is connected to the patient's brain, and the patient's intracranial pressure can be measured by the pressure sensor 502. According to the patient's intracranial threshold set in advance, the extraction of the accumulated water is suspended when the intracranial pressure is too low, and the extraction of the accumulated water is accelerated when the intracranial pressure is too high. It should be noted that since the extraction of accumulated water has a certain influence on the measurement of intracranial pressure, the electric telescopic cylinder 3 is set to pause at a time, so that the hydrocephalus in the drainage tube 5 is in a paused state, and the intracranial pressure is measured by the pressure sensor 502.

[0036] The working principle and use process of the present invention are as follows: the drainage tube 5 is connected to the drainage needle, and then the drainage tube 5 is connected to the patient's skull. Starting the electric telescopic cylinder 3 can drive the suction piston 205 to move downward. The downward movement of the suction piston 205 will slowly extract the hydrocephalus in the patient's skull through the drainage tube 5. The electric telescopic cylinder 3 is set to pause at a time, so that the hydrocephalus inside the drainage tube 5 is in a paused state. The pressure sensor 502 is used to measure the intracranial pressure. According to the threshold value set in advance, the extraction speed is controlled according to the intracranial pressure. After the hydrocephalus extraction is completed, the drainage tube 5 is disconnected from the drainage needle, and the shift handle 404 is used to drive the limit latch 403 to move downward, so that the limit latch 403 moves out of the limit hole 204, and the restriction on the storage barrel 2 is released. The storage barrel 2 can be moved forward to separate the connecting buckle block 207 from the clamping joint 301, and the storage barrel 2 can be removed separately to dump the extracted hydrocephalus inside.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
