Description
Technical field
The invention belongs to the field of medical instrument technology, are related to a kind of medicine dissolving device.
Background technology
Infusion is a kind of therapy being widely used, before being infused, it is often necessary to prepare some liquids, mesh
Before, the preparation of medicinal powder and medicament is generally completed using syringe, and specific operation is that syringe is inserted into medicinal liquid bottle and is extracted
Then a small amount of liquid is extracted syringe and is inserted into powdered medicine bottle, liquid medicine injection is entered in powdered medicine bottle, waits for that medicinal powder is completely molten with liquid
Xie Hou, then extract out in mixed liquor injection infusion bottle, during making up a prescription, since medicine bottle is sealing structure, it can be produced when operating
Raw certain Negative Pressure Difference, keeps operation laborious.
For this purpose, the applicant is improved the disadvantage present on, a kind of doser is applied on January 29th, 2008
The patent [patent No.：200810059615.6；Publication number：CN101229400A] comprising needle stand, casing and it is fixed on needle stand
On syringe needle, there is in syringe needle liquid-passing hole, casing to be fixed on needle stand, it is interior and have between casing certain that syringe needle is located at casing
The side in gap, casing is equipped with blow vent, and air-filtering membrane plug is provided in blow vent, and being equipped between casing and needle stand makes two
The clamping structure one that person is fixedly connected with and casing is made to form sealing with needle stand.
The doser of this kind of structure has the advantages that easy to assembly and rapid operation, but the doser of this kind of structure,
After use, syringe needle is still exposed at outside casing, needs housing being sleeved on outside casing, just syringe needle can be made not to be exposed in this way, but
It is to be sleeved on outside casing with housing, housing is easy to fall off, and syringe needle is caused still to be exposed, and people are arranging or clearing up this kind knot
When the doser of structure, there can be the risk pierced by syringe needle, there is infected possibility, there are some potential safety problemss.
Invention content
The purpose of the present invention is be directed to the above-mentioned problems in the prior art, it is proposed that a kind of medicine dissolving device, how is solution
Eliminate the security risk after existing medicine dissolving device use.
Object of the invention can be realized by the following technical scheme：A kind of medicine dissolving device, including needle stand, casing and syringe needle,
There is the syringe needle gap, bottom and the needle stand of the syringe needle to be fixedly connected with across casing and syringe needle and casing, and in syringe needle
Liquid-passing hole be connected with the endoporus in needle stand, which is characterized in that described sleeve pipe is detachably connected with needle stand, the bottom of described sleeve pipe
Portion is connected with compressible connecting tube, is equipped with spring in the connecting tube, one end of the spring is resisted against on needle stand, the other end
It is resisted against on casing, when casing and needle stand phase separation, the bottom of the connecting tube and the inside top of needle stand are interlockingly connected, described
Connecting tube extends under the effect of spring force makes syringe needle be located in casing and connecting tube.
This medicine dissolving device is matching used with syringe, in use, on the injector by the needle stand socket of this medicine dissolving device, so
After insert the needle into medicinal liquid bottle or in powdered medicine bottle, since casing and needle stand are fixedly connected with, i.e., extract medicine in syringe
Liquid or dissolving medicinal powder when casing will not shake, to make syringe needle not shake, will not be bent, stability is good, extract liquid or
It is easy to operate when person's dissolving medicinal powder, and when this medicine dissolving device does not use, since casing is to be detachably connected with needle stand, pass through
Applying certain external force makes casing be separated with needle stand, and whole of syringe needle is located at casing and connecting tube under the effect of spring force
In, syringe needle will not be exposed, and syringe needle would not pierce people, avoid infecting caused by accidentally injuring due to syringe needle, have a safety feature.
In a kind of above-mentioned medicine dissolving device, the connecting tube is telescoping tube, and the connecting tube and casing are integral structures,
