Abstract
The utility model relates to a medicine adding liquid sucking filter needle seat for a single steel needle. The utility model is characterized in that a filtering valve seat is arranged between an upper needle seat and a lower needle seat; the right side of the valve seat is provided with a liquid inlet valve, and the right side is provided with a liquid outlet valve. When liquid medicine is sucked, the liquid medicine enters an upper gap (2) from a channel (12) for inlet liquid and outlet liquid in order to cause opening sheets (13), (14) to close. The liquid medicine enters the liquid inlet valve from a liquid inlet channel (4) to open the opening sheet (8), (9) through filtering. The liquid medicine enters a lower channel (10) for inlet liquid and outlet liquid from a lower gap (19) to be sucked into a needle cylinder. When the liquid medicine is injected, the liquid medicine causes the opening sheets (8), (9) to close through the lower channel for inlet liquid and outlet liquid, and the lower gap (19), the liquid medicine enters a liquid inlet valve (15) from a liquid outlet channel (18) through filtering, and the opening sheets (13), (14) are opened to enter the upper channel (12) for inlet liquid and outlet liquid from the upper gap to flow out. The utility model has the advantages and the effects that the operation is simple, the medicine suction and filtering can be controlled automatically and completed synchronously, the medical expenses can be saved, the medical cost can be reduced, and the patients' safety of medical medication can be ensured.
Description
Technical field
This utility model relates to a kind of single draw point dosing and takes out notes filtration needle stand, belongs to medical appliance.
Background technology
In order to solve rubber particle and other particulates emissions that to sneak in the feeding operations herb liquid, improve clinical transfusion dosing matter child, healthy highly responsible to patient, the measure of all adopting at present the crosspointer operation to finish clinically, be that the first step is installed liquid medicine filter at the syringe head, the syringe needle that the liquid medicine filter upper end is installed the common or special-purpose band needle stand of a cover again aspirates required medicinal liquid, medicinal liquid is entered in the syringe by filter, to filter the particle matter that comes off in medicinal liquid owing to operating, second step, remove used syringe needle and liquid medicine filter from the syringe head, change the untapped common or special-purpose syringe needle of a cover again and be installed in the syringe head and inject operation again.Its weak point is that a dosing needs two cover syringe needles and a cover liquid medicine filter, brings the high burden of medical expense to the patient, increases the cost of medical institutions simultaneously, makes the medical worker increase labor intensity, operates loaded down with trivial details.
Summary of the invention
The purpose of this utility model in order to overcome the shortcoming and defect of above-mentioned prior art, is annotated the filtration needle stand and provide a kind of single draw point dosing to take out, thereby has been simplified operating process just, also reduces medical treatment cost and product cost, has guaranteed the safety of patient's pharmaceutical drugs.
The purpose of this utility model realizes by following technical proposal:
Single draw point dosing is taken out to annotate and is filtered needle stand, comprises needle stand (1), following needle stand (11), liquid in-out upper channel (12) and liquid in-out lower channel (10), it is characterized in that:
Between last needle stand and following needle stand, have one to filter valve seat (3), upper left-hand in filtering valve seat has a liquid valve (15), there is a feed liquor valve (7) on the right side, bottom, the feed liquor valve is made up of filter course (5) and valve body (6), valve body top is that cylindrical lower part is two left sides, the right closeable opening sheet (8 that is del, 9), left side opening sheet inner face and right openings sheet top overlap joint, filter course top communicates with feed pathway (4), feed pathway top is tubaeform, and mouth communicates with filtering the last gap of leaving on valve seat top (2) with the bottom inner platform of last needle stand, and lower openings sheet top communicates with the following gap (19) that filtration valve seat bottom is left with the top inner platform of following needle stand; Liquid valve (15) is made up of valve seat (17) and valve body (16), valve body lower portion is a cylindrical shape, top is two left and right closeable leg-of-mutton opening sheets (13,14), right openings sheet inner face and left side opening sheet top drum connect, the valve seat bottom communicates with liquid outlet channel (18), the tubaeform mouth of liquid outlet channel communicates with filtering the following gap of leaving the valve seat bottom (19) with the top inner platform of following needle stand, and upper opening sheet top communicates with the following gap (2) that filtration valve seat top is left with the inner platform of the bottom of last needle stand.
Owing to take technique scheme, it is simple to operate that compared with the prior art this utility model is had, and makes to take out to annotate to filter to control automatically and finish synchronously, saves medical expense, reduces medical treatment cost, guarantees the advantage and the effect of patient's pharmaceutical drugs safety.
