fig. 6 is an enlarged view of the structure of the portion I of fig. 5.
The specific implementation mode is as follows:
the invention is explained in further detail below with reference to the drawings.
Referring to fig. 1 to 6, the ventricular drainage tube comprises a catheter A and a drainage bag B, wherein a flow limiting valve C is additionally inserted between the catheter A and the drainage bag B, the structure formed by inserting the flow limiting valve C, the catheter A and the drainage bag B is used for preventing the drainage tube from being blocked in the later period, and a sterile tee joint can be additionally arranged for providing connection from the side surface for the extraction of an injector.
The flow limiting valve C comprises a valve barrel 1, a narrow channel cover 2 and a buffer barrel 3, wherein the narrow channel cover 2 is in threaded connection with one end of the valve barrel 1 and is used for allowing liquid to enter the valve barrel 1, and the buffer barrel 3 is in threaded connection with the other end of the valve barrel 1 and is used for outputting liquid. Namely, the guide pipe A is inserted in the extension port 21 of the narrow passage cover 2 of the valve cylinder 1, and the guide pipe sleeve above the liquid guide bag B is inserted in the extension port 31 of the buffer cylinder 3. The buffer cylinder 3 is internally provided with a buffer clapboard 31 with an inner wall extending towards the cylinder center, and the buffer clapboard 31 can be arranged in a single piece, multiple pieces and a ring shape, or in a ring shape.
The inner side of the valve cylinder 1, which is close to one side of the buffer cylinder 3, is provided with a supporting seat 4 with a plurality of through holes 41, a supporting rod 42 is arranged on the supporting seat 4, a spring 5 is sleeved on the supporting rod 42, and the tail end of the spring 5 is jacked into the tail end of a valve pin 6; the valve pin 6 is arranged on the opening edge of the narrow channel 21 of the narrow channel cover 2 which leads into the valve cylinder 1.
In the present invention, the throat cover 2 includes a cover seat 23, an inner blocking wall 24 extending from the inner side of the cover seat 23 and disposed between the extension opening 21 and the valve cylinder 1, and a sealing ring 25 disposed between the cylinder edge of the valve cylinder 1 and the inner blocking wall 24 and extending outward from the edge. In implementation, if the flow rate needs to be adjusted manually, the narrow channel cover 2 or the valve cylinder 1 can be slightly rotated to make the two displace relative to the height of the sealing ring 25, so that the valve pin 6 is separated from the mouth edge of the narrow channel 21 or the spring 5 is in a loose state, thereby reducing the liquid pressure borne by the valve pin 6 blocking the mouth edge of the narrow channel 21, i.e. the valve pin 6 can be retracted by less hydraulic pressure. Usually, it is used to confirm intracranial hypotension when no outflow of cerebrospinal fluid is found. When the skull is confirmed to be depressed, the narrow channel cover 2 and the valve cylinder 1 are screwed again to restore the valve pin 6 to the original opening edge of the overhead narrow channel opening 21.
When the drainage device is used, the catheter A to the drainage bag B do not need to be 10-15CM higher than the skull (namely the level of the external auditory canal), and the drainage bag B can be placed on one side of a sickbed lower than the skull by 10 CM.
Generally, the intracranial pressure of an adult is 0.7-2.0 kpa, the intracranial pressure of a child is 0.5-1.0 kpa, and aiming at the situation that the elasticity of a spring 5 in a ventricular drainage tube flow-limiting valve C corresponding to the adult and the child needs to be converted into the corresponding elasticity corresponding to the highest pressure of the adult or the child, the spring needs to be selected, and the spring needs to be marked for the adult or the child to use when the spring leaves a factory.
In addition, drainage bag B pegs graft in the buffer cylinder 3 below of drainage valve C, need again change after disinfecting to inserting the interface after drainage bag B fills with. The drainage valve C buffer cylinder is arranged not only for production consideration, but also for replacement by directly connecting other larger cerebrospinal fluid collecting containers under the condition that the drainage bag is inconvenient to replace at the later stage.
When in normal use, the catheter A is connected with the connecting pipe of the ventricle, and the drainage bag B is horizontally placed or hung on one side of the bed edge. When drainage is started, intracranial pressure is released rapidly, the cerebrospinal fluid pushes the valve pin 6 open to enter the valve barrel 1, then enters the buffer barrel 3 in threaded connection with the valve barrel 1 through the through hole 41 of the supporting seat 4, the cerebrospinal fluid advances reversely and is blocked by the buffer clapboard 31 due to the buffer clapboard 31 arranged on the inner wall of the buffer barrel 3, part of the cerebrospinal fluid flows out of the buffer barrel 3 through the gap between the buffer clapboards 31, but the part of the reversely blocked cerebrospinal fluid is flushed with the cerebrospinal fluid flowing into the valve barrel 1, so that the speed of the cerebrospinal fluid in the valve barrel 1 is slowed, and the cerebrospinal fluid flowing into the valve barrel 1 is also slowed. The configuration of the buffer baffles 31 is effective in slowing the rate of cerebrospinal fluid entry at the beginning of use, which also prevents the occurrence of air entrainment.
After the cerebrospinal fluid flows into the drainage bag B and the catheter A and the flow limiting valve C are both filled with the cerebrospinal fluid, the flow rate of the cerebrospinal fluid in the buffer cylinder 3 and the flow rate of the cerebrospinal fluid in the valve cylinder are gradually restored to be the same and integrated.
And because the restriction valve C exists, the catheter A and the drainage bag B which are connected with the two ends of the restriction valve C can be made to be very short, so that the phenomena of compression, distortion and folding of the catheter A are reduced. The patient can be turned over in the later period if necessary, and the drainage bag can be directly placed on one side of the pillow during the operation of treatment and nursing, which is very convenient.
With reference to fig. 3, as an improvement of the present invention, a plurality of fiber heating wires 43 are sealed in the support rod 42, and the connection end of the fiber heating wire 43 extends to the other side of the support seat, and a socket seat 45 and a battery chamber seat 7 with a plug 71 are arranged from the side to the cylinder wall of the valve cylinder 1. The plug 71 is rod-shaped, and has an anode and a cathode separated by an insulator, and the anode and the cathode are electrically opposite to the anode and the cathode in the jack 45.
In the invention, because the power of the fiber heating wire is low, a battery with a small volume can be placed in the battery chamber seat 7, so that the fiber heating wire 43 can be used for a long time, the heat productivity of the fiber heating wire is not large, and the flow of the lipid-containing substances in the cerebrospinal fluid is facilitated relative to the cerebrospinal fluid passing through the diameter surface of the valve barrel 1.
With continuing reference to fig. 4, as a further improvement of the present invention, a fiber heating wire 43 is disposed in the supporting seat, a connecting end of the fiber heating wire 43 extends to a jack seat 44 extending outward from one side of the supporting seat, and the jack seat 44 is matched with the battery compartment seat 7 externally provided with a plug.
Further, as a modification of the present invention, the battery chamber seat 7 further includes two upper and lower clamping frames 72 that can be clamped on the valve cylinder 1, and a battery chamber 73 disposed between the two clamping frames.
In the present invention, the clamping frame 72 is in a semi-circular arc shape, and the clamping frame can be clamped on the valve barrel 1 after expanding to both sides around the surface of the valve barrel 1 by pushing the battery chamber seat 73 onto the valve barrel 1. Because the power of the fiber heating wire 43 is small, the battery chamber 73 has small volume, and the valve cylinder 1 is not greatly influenced after the valve cylinder 1 is clamped.
Further, as an improvement of the present invention, the section of the buffer cylinder 3 is funnel-shaped, the section is the same as that of the valve cylinder, and the length of the buffer cylinder is at least one time of that of the valve cylinder.
Funnel-shaped flow rate which helps cerebrospinal fluid to enter the drainage bag can be restored to the speed of the cerebrospinal fluid flowing into the drainage valve C, and the entering of the cerebrospinal fluid in the valve cylinder is not influenced.
Further, as an improvement of the present invention, the buffer cylinder 1 is made of transparent material, and a color screening device (not shown) is clamped on the outer surface thereof; the color screening device (not shown) comprises an LED lamp clamped on one side surface and a photoresistor module on the other side surface, the LED lamp and the photoresistor module are connected with a single chip microcomputer chip, and one output end of the single chip microcomputer chip is connected with a buzzer or an alarm lamp.
In the invention, the normally drained cerebral cerebrospinal fluid is colorless and transparent and has no sediment, and the cerebral cerebrospinal fluid can be slightly bloody after 1-2 days of operation and then is converted into pale bloody. For example, there is a large amount of fresh blood in the cerebral cerebrospinal fluid after operation, or the color of the cerebral cerebrospinal fluid becomes darker gradually after operation, usually the cerebral ventricle bleeds, and bleeding is stopped by emergency operation when the amount of bleeding is excessive. Through from buffer 1 one side normal bright or regularly flash the LED lamp, through the blood colour becomes transmission medium in the buffer 1, the photoresistor module of reaction opposite side turns into the signal of telecommunication, sets up the signal of telecommunication that dangerous blood colour corresponds into the alarm, and the signal of telecommunication that every resistance module of light was dangerous blood colour changes into the singlechip chip promptly, and the singlechip chip promotes bee calling organ to cry or alarm lamp flashing is reported to the police. Therefore, the state of an illness can be found in time, and the method is effective and convenient.
In addition, because the singlechip chip is directly connected with pins for use, the whole color screening device (not shown) can be made very small.
Further, as an improvement of the invention, a magnet is arranged at the end of the valve pin 42, and when the testing intracranial pressure is too low, a magnet ring with opposite magnetic poles is sleeved outside the valve cylinder to push the end of the valve pin 42 away from the opening edge of the narrow channel.
Typically, such a configuration may be used to confirm cranial depression when no outflow of spinal fluid is found. When the skull is confirmed to be pressed down, the magnetic ring is removed, and the valve pin 6 can be restored to the original position of the top narrow opening 21.
Further, as an improvement of the present invention, the drainage bag B is placed in a bag holder (not shown), a weight sensor is disposed in the bag holder (not shown), and a nixie tube is disposed on an outer surface of the bag holder (not shown) for displaying a numerical value of the weight sensor.
When the drainage bag B needs to be led out continuously for multiple days without replacing, the arrangement of the bag seat can be adopted, the main board corresponding to the weight sensor can have a memory function, automatically records the cerebrospinal fluid amount of drainage every day, and can be read through the operation of the operation panel. In addition, the drainage bag B can be made to be very large by adopting the bag seat.
