Specific embodiment
In order to be illustrated more clearly that this utility model, this utility model is done into one with reference to preferred embodiments and drawings
The explanation of step.In accompanying drawing, similar part is indicated with identical reference.It will be appreciated by those skilled in the art that below
Specifically described content is illustrative and be not restrictive, and should not limit protection domain of the present utility model with this.
As shown in Figures 1 to 4, the present embodiment novel precise filter infusion device include Murphy's burette 1), tube for transfusion 2,
Accurate filter 23 and syringe needle 4, the Murphy's burette 1 are led with 23 fluid of the accurate filter by the tube for transfusion 2
It is logical, the accurate filter 23 and 4 fluid communication of the syringe needle；Accurate filter one is installed in the Murphy's burette 1,
The liquid outlet fluid communication of the liquid outlet of the accurate filter one and the Murphy's burette 1, in the Murphy's burette 1
Liquid passes sequentially through the liquid outlet of the accurate filter one and the liquid outlet stream of the Murphy's burette 1 enters the tube for transfusion 2.
When the liquid level in not Fei Shi drip tubes 1 is reduced to a certain degree, the accurate filter one in Fei Shi drip tubes 1 can be with
Delay or prevent the liquid in not Fei Shi drip tubes 1 to continue to flow downward, so play delay or prevent tube for transfusion 2 in liquid it is past
Lower movement, is easy to health care workers to connect bottle transfusion, mitigates the workload of medical worker and the worry of patient.
The accurate filter one is by one 5 groups of drainage screen 41 and the secondary filter film being wrapped in outside the drainage screen 41
Into the liquid in the Murphy's burette 1 passes sequentially through the secondary filter film 1 and the drainage screen 41 flow to the precision
The liquid outlet of filter one.The secondary filter film 1 can filter the microparticle that particle diameter is more than 1.2 microns.As not Fei Shi
When liquid level in drip tube 1 is reduced to a certain degree, the secondary filter film 1 outside the drainage screen 41 can be more effectively
The liquid not in Fei Shi drip tubes 1 is prevented to continue to flow downward.
Steam vent 12, the steam vent 12 and liquid in the accurate filter 23 are offered on the accurate filter 23
Space fluid conducting above body.After gas in the tube for transfusion 2 flows into the accurate filter 23 with liquid, gas
Discharged by the steam vent 12, thus before transfusion and in infusion process, the gas in tube for transfusion can be automatically drained out, can be with
Direct injection, without worrying that the air in tube for transfusion enters human body.
The steam vent 12 is turned on the space fluid above liquid in the accurate filter 23 by filter element.
Filter element can play the purpose for isolating liquid in the accurate filter 23 with outside air.
The accurate filter 23 includes air-permeative filter film 10, and has filter inlet 6 and filter liquid outlet
9 filter cavity 7；The air-permeative filter film 10 is located in the filter cavity 7, and the filter inlet 6 is worn
The air-permeative filter film 10 is crossed with the direct fluid communication in 7 inner space of filter cavity；The filter element is described
Gas filter membrane 10.Filter element can play the purpose for completely cutting off liquid in the accurate filter 23 with outside air.It is described
Air-permeative filter film 10 can be better protected from the dust in outside air or other harmful substances matter enters the accurate filter 23
It is interior, it is ensured that infusion safety.
The accurate filter 23 also includes the secondary filter film 3 11 in the filter cavity 7, the precision
Filter membrane 3 11 is located in the filter cavity 7, and is gone out with the filter positioned at 7 inner space of filter cavity
Between liquid mouth 9.The secondary filter film 3 11 can filter the microparticle that particle diameter is more than 1.2 microns, play to entering human body
Liquid carry out the purpose of secondary filter, it is ensured that infusion safety.
The filter inlet 6 is located at the top of the filter cavity 7, and the filter liquid outlet 9 is located at described
The bottom of filter cavity 7；The filter cavity 7 is in cylindrical and by filter upper cavity and filter lower chamber group
It is fixed together into, the filter upper cavity and the filter lower chamber.The steam vent 12 is provided with two；Institute
State 1 liquid feeding end of Murphy's burette and be provided with the liquid filling hole 13 with 1 fluid communication of the Murphy's burette, and the liquid filling hole 13
With feed tube 17 close to being set up in parallel；17 one end of the feed tube and medicine bottle fluid communication, the other end and the Murphy's burette 1
Fluid communication；This setup of the liquid filling hole 13 can play drainage so that when transfusion is started, without
Artificial force extrudes the Murphy's burette 1, and so that medicinal liquid in medicine bottle by only needing to the inlet opening 13 to open
Flow in the Murphy's burette 1 automatically by the feed tube 17.
Liquid blending device 14 is provided with the tube for transfusion 2, the accurate filter 23 is with the syringe needle 4 by sebific duct of infusing
15 fluid communications；Urgent liquid filling hole 16 with 2 fluid communication of the tube for transfusion is installed, when running into the state of an illness on the tube for transfusion 2
Urgent patient, when needing medicinal liquid to rapidly input in patient body, filling medicinal liquid by the liquid filling hole 13 needs relatively
The long time can just be input in patient body, and pass through the filling of urgent liquid filling hole 16 medicinal liquid, and medicinal liquid will flow into disease quickly
In human body, the purpose of urgent rescue is realized.
Air-permeative filter film 10 is different from the secondary filter film 1 and the secondary filter film 3 11, in use,
The air-permeative filter film 10 can pass through gas, hence in so that the gas in the accurate filter 23 can be discharged；And it is described
Gas can not pass through in use for secondary filter film 1 and the secondary filter film 3 11, thus realize double filtration gas
The effect of body, can be effectively prevented gas and enter in patient body.Accurate mistake in accurate filter one and accurate filter two
Filter membrane is differed, and that local filter membrane of steam vent filter membrane local with other is different, is not secondary filter film,
Air cannot pass through secondary filter film.
Novel precise of the present utility model filters infusion device and has following technological merit：1. dual secondary filter, filters
More than 1.2 microns of microparticle particle diameter, reduces microparticle and enters human body, so as to reduce the generation of infusion reaction and clinical doctor in transfusion
The generation for the treatment of accident, it is safer to medical personnel and patient；2. air filtering is crossed completely；3. without the need for first emptying tube for transfusion before infusing
In air, can not worry that the air in tube for transfusion enters human body, because of the secondary filter in Murphy's burette with direct injection
The accurate filter two of nethike embrane and distal end can cross air filtering completely；4. secondary filter nethike embrane not in Fei Shi drip tubes, can be with
In preventing tube for transfusion, liquid moves down, and is easy to health care workers to connect bottle transfusion, mitigates workload and the patient of medical worker
Worry；5, in preventing patient's blood vessel, backflow of blood is into tube for transfusion, it is to avoid patient's is terrified, and 6, infusion-completed pulled out after pin in pipe
Medicinal liquid will not be outbound flowed again, so protect the health of operating room, be also prevented from antibiotic and flow out the pollution to environment.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate this utility model example, and
It is not the restriction to embodiment of the present utility model, for those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms, all of embodiment cannot be exhaustive here,
It is every belong to the technical solution of the utility model it is extended obvious change or change still in of the present utility model
The row of protection domain.
