Ventricle drainer

Abstract

The invention relates to a ventricle drainer which is characterized by comprising a drain device and a negative-pressure liquid collecting device, wherein the main body of the drain device is a panel, the middle of the panel is hollow, the middle of the panel is provided with a screw, the head of the screw is provided with a hand wheel, and a slide block is connected on the screw through a screw nut; and the main body of the negative-pressure liquid collecting device comprises a liquid storage bag, a drain tube and a drain regulator, wherein the drain tube is inserted into the liquid storage bag and is hermetically connected with the inlet of the liquid storage bag, the drain regulator is sleeved outside the drain tube, a negative-pressure tube is hermetically connected with the inlet of the liquid storage bag, the other end of the negative-pressure tube is hermetically connected with a negative-pressure regulation ball, and a single-phase exhaust valve device is installed in the negative-pressure regulation ball. The whole panel is fixed in a proper position by a bed fixing frame, the hand wheel is rotated to regulate the height of the slide block, the single-phase exhaust valve device in the negative-pressure regulation ball enables the inside of the liquid storage bag to generate pressure difference, and liquid smoothly flows into the liquid storage bag through the drain tube, thereby ensuring that the liquid collecting effect is better in a certain pressure range, and the collected person is safe.

Description

technical field [0001] The invention relates to a ventricle drainage device for controlling the height of a drip bottle in a medical device to control the pressure generated by the medicinal liquid flowing into the human body. Background technique [0002] In the blood collection device of existing medical equipment, through such as Figure 7 The collection device shown mainly includes a liquid storage bag 21, a drainage tube 22 sealingly connected with the liquid storage bag 21, and a drainage regulator 23 that can slide outside the overflow tube to control the flow rate. The liquid storage bag 21 is a stretchable spring shape, collect blood by compressing its own liquid storage bag 21, and use a single drainage regulator 23 to control the blood flow rate. In this way, the efficiency of liquid collection can neither be improved nor the safety of liquid collection can be guaranteed; the equipment related to the drainage device is still in the In the original hook-type state,...

[0002] In the blood collection device of existing medical equipment, through such as Figure 7 The collection device shown mainly includes a liquid storage bag 21, a drainage tube 22 sealingly connected with the liquid storage bag 21, and a drainage regulator 23 that can slide outside the overflow tube to control the flow rate. The liquid storage bag 21 is a stretchable spring shape, collect blood by compressing its own liquid storage bag 21, and use a single drainage regulator 23 to control the blood flow rate. In this way, the efficiency of liquid collection can neither be improved nor the safety of liquid collection can be guaranteed; the equipment related to the drainage device is still in the In the original hook-type state, when a patient is sick and needs an IV or injects a medicinal solution in the brain, he simply nails a nail on a high wall or a wooden board, and then hangs the fluid storage bag 21 through a rope. on the nail

In this way, when the liquid storage bag 21 is injected into the human body, it will easily shake left and right due to external collisions, causing air to enter the injection port to cause backflow, and as the liquid medicine in the bottle decreases, the internal pressure will also increase. Even if there is a slight change, for the person undergoing brain injection, a little pressure difference will also have serious consequences. In this way, the liquid storage bag always maintains a certain height, which will affect the normal injection process
