Abstract
The utility model relates to a medical tapping device, comprising a medical pressure pump and an air filter. The air filter is provided with a liquid cavity and an air cavity which are separated from each other; the liquid cavity is provided with a liquid inlet, an air inlet pipe and an air outlet; the air cavity is provided with an air inlet and an air outlet; the air outlet of the air cavity and the air inlet pipe of the liquid cavity are connected by a guide tube; the air outlet of the liquid cavity and the medical pressure pump are connected by the guide tube. The utility model has the advantages of simple structure, low cost and convenient operation, the labor intensity of medical personnel is lightened greatly, and the asepticizing operation for pumping and allocating liquid is realized.
Description
This utility model relates to a kind of clinical drawing liquid, the simple and easy pumping device that uses in the dosing process.
At present, the big bottle intravenous drip liquid that uses in the hospital clinical all is directly to be prepared by medical personnel before the clinical use.That is,, be injected into then in the liquid of big bottle with earlier the medicinal liquid in the injection being extracted out by medical personnel through sterilization, germ-resistant needle tubing.The big bottle of this artificial clinical preparation drip liquid, both loaded down with trivial details, time-consuming again, effort if careless slightly syringe needle or the nook closing member of touching also can cause big bottle drip liquid to carry disease germs, jeopardizes the healthy of patient.
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of simple in structure, easy to use, can guarantee the medical simple and easy liquid extracting device of sterile working in the drawing liquid process.
Specific embodiments of the present utility model is as shown in drawings:
Fig. 1 is the structural representation of this utility model embodiment
Below with reference to the accompanying drawings embodiment of the present utility model is elaborated:
Medical tapping device contains a medical pressure pump 1 and an air cleaner 2. At sky Be provided with a fluid chamber 3 and an air chamber 4, fluid chamber 3 and air chamber 4 in the air filter 2 Mutually isolation. On fluid chamber 3, be provided with inlet 7, air inlet pipe 8 and gas outlet 6. On the air chamber, be provided with air inlet 11 and gas outlet 10. Gas outlet 10 Hes of air chamber 4 Between the air inlet pipe 8 of fluid chamber 3, adopt conduit 9 to connect. In order to guarantee the space in the air chamber Keep germ-free condition, the air inlet pipe 8 on the fluid chamber should place under the interior liquid level of fluid chamber. Liquid Between the gas outlet 6 and medical pressure pump 1 on the chamber, adopt conduit 5 to connect.
During drawing liquid, with a conduit 12 that has syringe needle air inlet on the air chamber of air filter 11 and big bottle liquid 15 are coupled together earlier.The conduit 13 that one of reuse has double needle couples together injection 14 and big bottle liquid 15, starting the medical pressure pump then bleeds, make in air filter 2 and the big bottle liquid and all produce negative pressure, medicinal liquid in the injection just can be sucked in the big bottle liquid very easily like this, thereby not only guaranteed carrying out smoothly of drawing liquid operation, and guaranteed the asepticize of drawing liquid process.
This utility model is simple in structure, with low cost, easy to use, and it has not only alleviated medical workers significantly, and has realized the asepticize operation of drawing liquid dosing.
