Description
Technical field
The present invention relates to medical material tech fields, and in particular to a kind of reusable formula delivery device of pocket.
Background technology
Common infusion model is that medicine bag or medicine bottle are suspended on higher place, and liquid will produce in higher place
Potential energy, traditional device are kinetic energy using the pinnacled potential energy of liquid, provide the power of infusion.Defect one, this infusion
Mode the space occupied is larger, and needs tender to follow when patient needs to go to toilet and lift infusion bottle to higher than head
Top, operation are fairly cumbersome.The lighter patient of the state of an illness originally completely can be freely movable, but is fettered by such infusion device
In the head of a bed.Defect two, the woven hose of original infusion device are longer, are easy accidentally surprisingly to be wound, cause safety accident, because
This needs to seek a kind of safe and reliable device newly to solve above-mentioned technical problem.
Invention content
The present invention overcomes the shortcomings of that background technology provides a kind of reusable formula delivery device of pocket, designs and develops this
The purpose of product：The first, the case where portability is quite strong, carries this delivery device, and patient's self-condition allows while administration
Out-of-bed activity that down can be voluntarily, can go to the toilet, can stroll in the park, can stroll supermarket.The second, longer infusion tube need not be used,
Dangerous generation of stumbling to avoid.
The present invention provides following technical proposals：A kind of reusable formula delivery device of pocket, the delivery device include
Medicine storing pot 1 leads medicine hose 2, injection medicine needle 3, and described one end for leading medicine hose 2 is connect with the medicine storing pot 1, described to lead medicine hose
2 other end is connect with the injection medicine needle 3, and the delivery device further includes flowmeter 4, pressure reducing valve 5, cooling gas check valve 6, described
Cooling gas check valve 6 is connected to the inner cavity of the medicine storing pot 1, and the flowmeter 4 is led set on described in the pipeline of medicine hose 2, described
Pressure reducing valve 5 leads medicine hose 2 and 1 junction of the medicine storing pot described in being set to, and has high pressure air cavity 7, the high pressure in the medicine storing pot 1
The pressure of air cavity 7 is 0.5~3.5MPa.
Further, the pressure reducing valve 5 is AR10-02 type tubular type pressure regulator valves.
Further, the connection type of the other end for leading medicine hose 2 and the injection medicine needle 3 is detachable connection.
Beneficial effects of the present invention：Gas is filled with by cooling gas check valve 6 into high pressure air cavity 7 so that in high pressure air cavity 7
Air pressure height stops inflation when air pressure reaches within the scope of 0.5~3.5MPa in high pressure air cavity 7.Cooling gas check valve 6 rises
The effect not leaked outside to latching air.It opens 5 liquid of pressure reducing valve and is flowed out from injection medicine needle 3 by leading medicine hose 2.High pressure air cavity 7
In air pressure liquid be provided convey power, pressure reducing valve 5 is for adjusting discharge pressure, the pressure of entire medicine storing pot 1 in infusion process
Power continuously decreases, when 1 herb liquid of medicine storing pot it is defeated to the greatest extent after, air pressure in medicine storing pot 1 is close to an atmospheric pressure.It can be by this during use
The medicine storing pot 1 of device is placed in the pocket of patient, can also take use.The infusion that volume is big, weight is heavy need not be used
Frame.To which the present apparatus has the advantages that.The first, portability is quite strong, carries this delivery device, patient while administration
Self-condition allow in the case of can be voluntarily out-of-bed activity, can go to the toilet, can stroll in the park, supermarket can be strolled.The second, it need not adopt
With longer infusion tube, the dangerous generation of stumbling to avoid.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
Below in conjunction with attached drawing, the invention will be further described with specific embodiment.
In Fig. 1：Medicine storing pot 1 leads medicine hose 2, injection medicine needle 3, flowmeter 4, pressure reducing valve 5, cooling gas check valve 6, high pressure gas
Chamber 7.
A kind of reusable formula delivery device of pocket, the delivery device include medicine storing pot 1, lead medicine hose 2, injection medicine needle
3, described one end for leading medicine hose 2 is connect with the medicine storing pot 1, and the other end for leading medicine hose 2 connects with the injection medicine needle 3
It connects, which is characterized in that the delivery device further includes flowmeter 4, pressure reducing valve 5, cooling gas check valve 6, the cooling gas check valve 6 and institute
The inner cavity connection of medicine storing pot 1 is stated, the flowmeter 4 is led set on described in the pipeline of medicine hose 2, and the pressure reducing valve 5 is set to described
Medicine hose 2 and 1 junction of the medicine storing pot are led, has the high pressure air cavity 7, the pressure of the high pressure air cavity 7 to be in the medicine storing pot 1
0.5~3.5MPa.
The pressure reducing valve 5 is AR10-02 type tubular type pressure regulator valves.It can be reduced the higher fluid pressure of pipeline before valve to valve
Level needed for pipeline afterwards.This pressure reducing valve stable working is without friction；Without spring in valve body, therefore without spring corrosion, metal fatigue
The worry of failure；Favorable sealing property is non-leakage, does not especially influence water flow while decompression.
The connection type of the other end for leading medicine hose 2 and the injection medicine needle 3 is detachable connection.It can screw thread rotation
Connect, be clamped, be socketed etc..Such design, which is the present apparatus, to be reused by replacing syringe needle.
Flowmeter 4 using suspended body flowmeter, suspended body flowmeter be with float in vertical taper pipe as flow becomes
Change and lift, the volume flow instrument for changing the circulation area between them to measure, also known as spinner flowmeter.
Cooling gas check valve 6 is a kind of air route membrane one-way valve, is made of valve body, valve deck and diaphragm.One end of valve body is
Connector equipped with central through hole, the other end are then connected equipped with threaded hole with valve body.Placed in valve body cavity it is a piece of or it is a piece of with
On diaphragm.Central through hole is equipped on valve deck, one end is connector, and the other end stretches into valve body cavity and is equipped with one in its end point
Item or a plurality of air channel.By diaphragm unidirectional effect is realized under stream pressure effect.
It will be initially injected liquid by installing the interface of cooling gas check valve 6 in medicine storing pot 1 during use, then installed
This cooling gas check valve 6 so that form a high pressure air cavity 7 in medicine storing pot 1, then filled into high pressure air cavity 7 by cooling gas check valve 6
Enter gas so that air pressure height in high pressure air cavity 7, when air pressure reaches within the scope of 0.5~3.5MPa in high pressure air cavity 7,
Stop inflation.Cooling gas check valve 6 plays the role of latching air and does not leak outside.5 liquid of pressure reducing valve is opened by leading medicine hose 2 from note
Penetrate the outflow of medicine needle 3.Air pressure in high pressure air cavity 7 provides liquid and conveys power, and pressure reducing valve 5 is being infused for adjusting discharge pressure
The pressure of entire medicine storing pot 1 continuously decreases in the process, and after 1 herb liquid of medicine storing pot is defeated most, the air pressure in medicine storing pot 1 is big close to one
Air pressure.
