Anesthetic drug proportioning device

Abstract

The invention provides an anesthetic drug proportioning device; uniformity during anesthetic drug proportioning is achieved, use and independent proportioning operation can be well achieved accordingto a liquid preparation area and a liquid storage area which can be communicated and isolated, and flexibility is high; according to the technical scheme, the anesthetic drug proportioning device comprises a solution tank and a piston flat plate, the interior of the solution tank is divided into a solution preparation area and a solution storage area by the piston flat plate; a stepped hole is formed in the center of the piston flat plate; a stirring rod and a pull rod are arranged in the solution tank; a sealing pressing block is arranged at the lower end of the pull rod; the diameter of thesealing pressing block is smaller than the diameter of a large hole of the stepped hole and smaller than the diameter of a small hole of the stepped hole, the upper end of the pull rod penetrates through a top plate of the solution tank and the upper end of a driving shaft, the pull rod can move up and down along the driving shaft but cannot rotate, the upper end of the driving shaft is connectedwith an adjusting nut, and the adjusting nut is in threaded connection with the pull rod; the device is novel in conception and ingenious in structure.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to an anesthetic drug proportioning device. Background technique [0002] In the current medical treatment system, anesthesia is a very widely used drug, especially necessary for surgery. [0003] Now when configuring anesthetic drugs, it is often necessary to mix multiple raw materials strictly according to the ratio to mix and stir to support the anesthetic drugs. Due to the need to use different doses according to different patients during the use of anesthetic drugs, this leads to It is necessary to configure different amounts of narcotic drugs during the configuration process, but in the actual operation process, sometimes the narcotic drugs need to be reconfigured for some reasons during use. At this time, if the new additives are directly added to the previous When it is in the prepared solution, this will lead to an unbalanced ratio of the so...

[0003] Now when configuring anesthetic drugs, it is often necessary to mix multiple raw materials strictly according to the ratio to mix and stir to support the anesthetic drugs. Due to the need to use different dosages according to different patients during the use of anesthetic drugs, this leads to It is necessary to configure different amounts of narcotic drugs during the configuration process, but in the actual operation process, sometimes the narcotic drugs need to be reconfigured for some reasons during use. At this time, if the new additives are directly added to the previous When the solution is prepared, this will lead to an unbalanced ratio of the solution, but if it is prepared with other devices alone, it will be more troublesome, and the use of multiple devices will also increase the cost to a certain extent
