Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: the utility model provides a hydrops drainage device for neurosurgery, is including having open-ended stock solution bottle 1, and this opening part joint has rubber buffer 2, and rubber buffer 2 carries out the shutoff to stock solution bottle 1, prevents the weeping, and air exhaust device is installed at rubber buffer 2's top.

The air extracting device comprises an air extracting pump 3, a first inserting needle 4 is fixedly connected to the position of an air inlet in the middle of the bottom of the air extracting pump 3, the first inserting needle 4 is made of stainless steel or rigid plastic, a small ball 5 is arranged in the bottom cavity of the first inserting needle 4, the size of the small ball 5 is matched with the inner cavity of the first inserting needle 4, when the air extracting pump 3 is started, a gap between the small ball 5 and the inner cavity of the first inserting needle 4 can pass through gas but cannot pass through particles slightly, the first inserting needle 4 penetrates through the rubber plug 2 to extend to the top in the cavity of the liquid storage bottle 1, an air outlet pipe 6 is fixedly connected to the position of the air inlet in the middle of one side of the air extracting pump 3, a second inserting needle 7 is inserted into the top, far away from the first inserting needle 4, the second inserting needle 7 is made of stainless steel or rigid plastic, a hose 8 is fixedly connected to the top of the second inserting needle 7, the, a drainage needle 9 is fixedly connected to one end of the hose 8 far away from the second insertion needle 7, the drainage needle 9 is made of stainless steel or rigid plastic, but the second insertion needle 7, the hose 8 and the drainage needle 9 can also be disposable plastic products in consideration of sanitation and cost.

Because stock solution bottle 1 is soft elasticity plastic bottle, so when the drawing liquid, start aspiration pump 3, aspiration pump 3 can take out shrivelled with stock solution bottle 1, negative pressure in the stock solution bottle 1 this moment, install pressure head 13 on the hose 8, pressure head 13 plays the effect of switch and speed governing, the switch is then the inner chamber that the extrusion closed living hose 8, the speed governing is then the speed of adjusting the drawing liquid, wait to stock solution bottle 1 take out shrivelled complete back, slowly open pressure head 13, under the negative pressure effect in stock solution bottle 1, make the hydrops flow into stock solution bottle 1 through hose 8 in collect can, along with the balance of pressure in the stock solution bottle 1 and the elastic action of stock solution bottle 1 self, stock solution bottle 1 resets gradually and is full, because the bottom of first contact pin 4 is inserted at 1 intracavity top position of stock solution bottle, the shutoff effect of pellet 5 in addition, the hydrops hardly enters into in first contact pin 4.

Install switch 11 on the aspiration pump 3, switch 11 is connected with aspiration pump 3 on one side, and power transformer 12 is connected to the another side, and aspiration pump 3 is the small-size silence vacuum pump of 24V, and after the switch on, aspiration pump 3 does not switch on, and until opening switch 11 after, aspiration pump 3 just begins the function, and safety insurance to sum up, compare in prior art, this device easy operation, efficient, it is more convenient, swift to use.

The working principle is as follows: this hydrops drainage device for neurosurgery uses, at first place 1 is vertical with stock solution bottle, after the switch on, aspiration pump 3 does not circular telegram, until opening behind switch 11, aspiration pump 3 just begins the function, aspiration pump 3 can be with stock solution bottle 1 take out the flat, negative pressure in the stock solution bottle 1 this moment, after that, press head 13 is slowly opened, in stock solution bottle 1 under the negative pressure effect, make the hydrops flow into in stock solution bottle 1 through hose 8 and collect can, the balance of pressure and the elastic action of stock solution bottle 1 self in the stock solution bottle 1 along with, stock solution bottle 1 resets gradually and is full, after filling up thoroughly resetting in stock solution bottle 1, the hydrops extraction finishes, pull out first contact pin 4 and second contact pin 7 this moment, can with stock solution bottle 1 take off.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
