Description

A kind of alkali metal memotron

Technical field

The utility model relates to medical treatment device, specifically, relates to a kind of alkali metal memotron.

Background technology

The alkali metal such as Na-K alloy, can be injected in tissue, with the heat-producing chemical reaction that in tissue, naturally occurring water generates is strong, and realize focus ablation. Because reaction is violent, only need trace just can reach efficient heating ablation object. But, also just because of this feature of alkali metal thermotherapy, make will especially take care in practical operation, at inhalation syringe and in being expelled to tissue time, all to avoid alkali metal fluid to contact with air or water. At present, in use all there is safety issue more or less in traditional syringe, still can not serve as the in addition extensive use of safe and reliable medicine equipment.

CN204484292U discloses a kind of disposable squash type alkali metal injection device, comprises alkali metal memotron, entry needle and injection control assembly; One end of described entry needle is angle, and the other end is flat mouth, and one end of flat mouth is outside equipped with connection overcoat, and described entry needle is connected and connects overcoat with one end of alkali metal memotron and is enclosed within outside connecting portion; The other end of alkali metal memotron is connected with described injection control assembly; Described alkali metal fluid and protection liquid are placed in alkali metal memotron.

Then, syringe is inserted in the alkali metal fluid of alkali metal pipe, draw enough alkali metal fluids by use amount, when syringe is extracted out, draw trace protection liquid.

(3) beneficial effect

The alkali metal memotron that the utility model provides, can make syringe extract out time, draws trace protection liquid, to avoid the alkali metal fluid in syringe to contact with air or water after syringe is extracted out, also can avoid syringe needle head part to speckle with alkali metal fluid.

The utility model is all in the alkali metal memotron of protection liquid by alkali metal Fluid Sealing at two ends, is convenient to transport and stores. Being equipped with independent protection liquid pipe, for the air of exhaustjet pin, owing to protecting liquid pipe and alkali metal pipe not to communicate, entering alkali metal pipe so do not have in this course air, is a kind of safe apparatus and method of simply and not losing.
