Abstract
The utility model relates to a medical close valve, which is mainly used for sterilizing formulations, chamber formulations, and the clinic is composed of a base, a valve core, a valve body, a valve cover, a pedal, or an electromagnetic valve, etc. Through a foot-operated control pedal or an electric control valve core, the medical close valve can realize the used purposes of the formulations and the clinic. Firstly, the medical close valve which is convenient to be operated by one person has the advantages of novel and simple structural design and safe and convenient operation; secondly, the quality of the sterilizing formulations is high and is in conformity with the 90-version requirement of the Chinese pharmacopoeia, and the qualification rate can be improved over 85% than the prior art.
Description
This utility model belongs to medical apparatus and makes the field.
Prior art in this utility model prior art field is: the stop valve that the preparation of existing hospital sterile preparation department and a clinical line are adopted in coloclysis, gastric lavage, department of obstetrics and gynecology, surgical operation flushing is hand switch or sebific duct gives a discount into utensils such as extruding sealing.
Purpose of design of the present utility model is: the medical stop valve of design a kind of medical foot-propelled or solenoid control Qi Guan, opening, with protection during sterilization preparation the quality of the pharmaceutical preparations and be convenient to clinical one man operation and use.
Design of the present utility model is: medical stop valve is divided into medical foot-propelled stop valve and two kinds of organization plans of electro-medical magnet valve stop valve.1, the bottom of the valve body 3 of medical foot-propelled stop valve is screwed on the base 1, is shaped on locating hole 11 on the base 1; Spool 4 is positioned at valve body 3 and is equipped with a stage clip 2 at the in-core intracavity of spool 4; Valve gap 6 passes the core bar of spool 4 and is screwed in the top of valve body 3; Spool 4 is made of core body and core bar, and is shaped on intake chute 9 on one's body at core; Pedal 8 is positioned on the core bar of spool 4; Two pipe joints 5 are symmetrically located at two of the body bodies of valve body 3 and are communicated with valve body.Its operation principle: base 1 is fixed on required place, and transfusion or system liquid flexible pipe are enclosed within respectively on the pipe joint 5.When preparation or clinical use, push down on the pedal 8, make the lumens aligned of intake chute 9 and pipe joint 5 on the spool 4, liquid will be used for preparation or be used for clinical through the stop valve infusion tube of flowing through.Not the time spent, unclamp foot, spool 4 resets under the effect of stage clip 2 and reaches the purpose of closing.2, the bottom of the valve body 3 of electro-medical magnet valve stop valve is screwed on the base 1, and is shaped on locating hole 11 on base 1; Spool 4 is positioned at valve body 3 and is equipped with a stage clip 2 at the in-core intracavity of spool 4; Valve gap 6 passes the core bar of spool 4 and is screwed in the top of valve body 3; Spool 4 is made of core body and core bar, and is shaped on intake chute 9 on one's body at core; Electromagnetic valve 10 is positioned on the valve gap 6 and the contact of electromagnetic valve is positioned on the core bar upper end of spool, and two pipe joints 5 are symmetrically located at two of the body bodies of valve body 3 and are communicated with valve body 3.Its operation principle: transfusion or system liquid flexible pipe are enclosed within respectively on the pipe joint 5, and stop valve is fixed on required place, and the connecting line of the electromagnetic valve 10 in gauge tap and the stop valve is connected.When preparation or clinical use, 10 adhesives of Closing Switch electromagnetic valve, its contact forces spool 4 to move down, make intake chute 9 and two pipe joint lumens aligned on the spool 4, liquid is used for preparation or clinical through the stop valve infusion tube of flowing through, and not the time spent, opens gauge tap, electromagnetic valve disconnects, and moves on the spool 4 and closes.Medical stop valve adopts rustless steel or titanium material to make.
This utility model compared with prior art, the one, it is simple, safe and convenient to use to have the structural design novelty, is convenient to clinical people's independent operation; The 2nd, sterilization preparation quality height meets 90 editions pharmacopeia (China) requirement, and through 3.8 ten thousand bottles of 42 batches of meters on probation, batch qualification rate improves more than 85% than prior art, 500,000 milliliters of every batch of saving distilled water.
Description of drawings:
Fig. 1 is the structural representation of medical foot-propelled stop valve.
Fig. 2 is the structural representation of electro-medical magnet valve stop valve.
Embodiment:
1 pair of medical foot-propelled stop valve is done with narration in conjunction with the accompanying drawings.
Be shaped on locating hole 11 on the base 1, be mainly used in standing valve; The bottom of valve body 3 is screwed on the base 1; Spool 4 is made of core body and core bar, and is shaped on intake chute 9 on one's body at the core of spool 4, and spool 4 is positioned at valve body 3 and is equipped with a stage clip that is used to reset 2 at the in-core intracavity of spool 4; Valve gap 6 passes the core bar of spool 4 and is screwed in the top of valve body 3; Pedal 8 adopts sunk screw 7 and is fixed on the core bar of spool 4; The body that two pipe joints 5 are screwed in valve body 3 symmetrically is communicated with on one's body and with valve body 3.
2 pairs of electro-medical magnet valve stop valves are done with narration in conjunction with the accompanying drawings.
On the basis of medical foot-propelled stop valve, take down pedal 8, sunk screw 7, electromagnetic valve 10 is adopted be bolted on the valve gap 6 and the contact of electromagnetic valve 10 is positioned on the core bar upper end of spool 4, gauge tap is connected with the line of electromagnetic valve 10 and gets final product.
