Embodiment Construction

[0023] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 , figure 2 and Figure 5 As shown, the structure of a hemostatic drug rapid launch device in this embodiment includes a cylinder body 1, which is provided with an air storage chamber 11, a drug storage chamber 12, a piston 2, and the piston 2 and the valve core 5 are plugged in. At the same time, the valve The core 5 is inserted into the cylinder body 1 .

[0025] The structure of the piston 2 includes a piston head 23 , a rod portion 25 and an end cover 22 . The end cap 22 is an airtight cavity formed after closing the outlet of the medicine storage chamber 12 , in which the hemostatic medicine 7 is stored.

[0026] Specifically, a limit hole 21 is opened on one side of the piston head 23, such as Figure 4 As shown, the limiting hole 21 includes a narrow hole section 211 and a wide hole section 212 .

Abstract

The invention provides a rapid hemostatic emitting device. The device comprises a cylinder body, a piston and a valve element, wherein an air storage cavity and a medicine storage cavity are formed inthe cylinder body; a channel is formed between the air storage cavity and the medicine storage cavity; the piston is arranged in the medicine storage cavity; one end of the piston is used for extending into the channel to seal the channel, and the other end of the piston is used for sealing the medicine storage cavity; and the valve element is matched with the piston in an inserted connection mode, the piston is limited in the medicine storage cavity, or the piston is released to be pushed by compressed air in the air storage cavity to move towards the exterior of the medicine storage cavityby a certain distance, and therefore a hemostatic in the medicine storage cavity is emitted out. Through the cooperation of the valve element and the piston, the hemostatic is sprayed out through thecompressed air, so that the medicine emitting speed is greatly increased, and the operation convenience and the device reliability are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices for delivering hemostatic drugs, in particular to a rapid launching device for hemostatic drugs. Background technique [0002] The hemostatic drug delivery device is used for first aid during bleeding during medical operations or at the scene of traffic accidents, and plays an important role in hemostasis and drug delivery for large wounds. Among the existing technical solutions developed at home and abroad, most of the medical hemostatic drug delivery devices mostly use a syringe to push the hemostatic drug to the bleeding wound. The pushing speed is slow, which affects the hemostasis time of the wound, and is inconvenient to use. Certain requirements, the scope of applicable places is small. Contents of the invention [0003] The object of the present invention is to provide a rapid launching device for hemostatic drug, which solves the problems of inconvenient operation and slow deli...
