Description
Technical field
The present invention relates to a kind of transfusion device, particularly relate to the accurate film of a kind of Anti-bubble and stop liquid transfusion device.
Background technology
At present, the transfusion device of market is varied, and people, when using transfusion device transfusion, often have some impurity in medicinal liquid, especially some traditional Chinese medicine liquid, these impurity have certain influence to health, existing transfusion device does not have special defecator, and medicinal liquid in infusion bottle want defeated to the greatest extent time, just need transfusion needle to extract from human body, " blood back " phenomenon will be caused if do not extract, have very large harm to patient body like this.
Summary of the invention
The present invention, in order to solve the above-mentioned deficiency of prior art, proposes the accurate film of a kind of Anti-bubble and stops liquid transfusion device.
In order to solve the problems of the technologies described above, the present invention is by the following technical solutions: the accurate film of a kind of Anti-bubble stops liquid transfusion device, comprise tube for transfusion, perforator, dropping funnel, flow regulator, female Luer and transfusion needle, it is characterized in that: described tube for transfusion is also provided with the accurate film of an Anti-bubble and stops liquid device, the accurate film of this Anti-bubble stops liquid device and comprises and coordinate by fore shell and back cover the circular housing formed, and circular housing inside is cavity structure; Described back cover upper end is provided with water inlet pipe, and lower end is provided with outlet pipe, and back cover shell wall is laterally provided with correspondence and is arranged on waterwall below water inlet pipe; Described fore shell shell wall is provided with to coordinate and holds out against the overboard wall with waterwall, and overboard wall is provided with multiple water falling hole, and fixes a filter membrane by sealing between the overboard wall of described waterwall circular housing interior separation is become two accommodation spaces; The upper end mouth of pipe of described outlet pipe is provided with a secondary filter film.
Further, described fore shell shell wall is provided with multiple steam vent, and the inner surface of steam vent posts breathing waterproof film, and steam vent is arranged on the below of overboard wall.
Further, described outlet pipe extend into certain altitude in circular housing.
Further, described tube for transfusion is bimetallic tube, and wherein, interior pipe adopts not to be made containing DEHP plasticizer material, and outer tube adopts PVC material to make.
Compared with prior art, it is ingenious that the accurate film of the Anti-bubble that the present invention adopts stops liquid device design, circular housing is separated into two accommodation spaces by the filter membrane arranged in device, first access to plant inner liquid medicine is through waterwall and overboard wall effect, allow medicinal liquid enter and be provided with steam vent and breathing waterproof film side, the generation of bubble when this makes it possible to prevent from infusing, again after filter membrane filters, just the impurity in medicinal liquid can be stopped, and be arranged on the secondary filter film of outlet pipe, can again filter the impurity in medicinal liquid, and secondary filter film can at the end of transfusion be fast, prevent medicinal liquid adverse current, this device decreases the use of secondary filter film, save cost greatly, be worth significantly promoting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the side cross-sectional views that the accurate film of Anti-bubble of the present invention stops liquid device;
Fig. 3 is the axonometric chart that the accurate film of Anti-bubble of the present invention stops liquid device.
Detailed description of the invention
Below in conjunction with drawings and Examples, invention is described in detail.
As shown in Figure 1, 2, 3, the accurate film of the Anti-bubble that the present invention proposes stops liquid transfusion device, comprise tube for transfusion 1, perforator 2, dropping funnel 3, flow regulator 4, female Luer 5 and transfusion needle 6, tube for transfusion 1 is bimetallic tube, wherein, interior pipe adopts not to be made containing DEHP plasticizer material, and outer tube adopts PVC material to make.
Tube for transfusion 1 is also provided with the accurate film of an Anti-bubble and stops liquid device, the accurate film of this Anti-bubble stops liquid device and comprises and coordinate by fore shell 8 and back cover 9 circular housing 7 formed, and circular housing 7 inside is cavity structure; Back cover upper end is provided with water inlet pipe 91, and lower end is provided with outlet pipe 92, and outlet pipe 92 extend into certain altitude in circular housing, and back cover shell wall is laterally provided with correspondence and is arranged on waterwall 93 below water inlet pipe 91; Fore shell 8 shell wall is provided with to coordinate and holds out against the overboard wall 81 with waterwall 91, overboard wall is provided with multiple water falling hole, and fix a filter membrane 10 by sealing between the overboard wall 81 of waterwall 91 circular housing 7 interior separation is become two accommodation spaces, fore shell 8 shell wall is provided with multiple steam vent 82, the inner surface of steam vent 82 posts breathing waterproof film 83, and steam vent 82 is arranged on the below of overboard wall 81; The upper end mouth of pipe of outlet pipe 92 is provided with a secondary filter film 94.
When infusing, refer to Fig. 2 and Fig. 3, the flow direction of medicinal liquid when the direction of arrow is wherein transfusion, first medicinal liquid enters in circular housing from water inlet pipe 91, due to the effect of waterwall 93, medicinal liquid can only fall from overboard wall above, enter in the accommodation space on the left of filter membrane 10, in this accommodation space, can be acted on by steam vent 82 and breathing waterproof film 83, be exhausted process, again through the accommodation space of filter membrane 10 to opposite side, now in medicinal liquid, impurity is stopped and cannot be passed through filter membrane, filter membrane 10 is common filter membrane, cheap, cost is low, the medicinal liquid now entering into another accommodation space slowly overflows the outlet pipe of mouth of pipe certain altitude, flow out from outlet pipe again, the secondary filter film 94 on the mouth of pipe is now needed to filter, secondary filter film 94 can thoroughly by the contaminant filter in medicinal liquid, secondary filter film is by hydrophilic, when touching medicinal liquid, micropore on secondary filter film opens, medicinal liquid is dirty, when transfusion will at the end of, liquid level in accommodation space cannot continue to overflow and enters into outlet pipe 92, now, secondary filter film has departed from medicinal liquid, micropore on film is closed, isolated air, so just allow liquid level in outlet pipe cannot continue to decline, stopped transfusion, prevent " blood back " phenomenon to produce.
In the present invention, the mouth of pipe of outlet pipe is provided with certain altitude, which prevent the generation of bubble, and the contamination precipitation through filter membrane 10 can be allowed to get off, the secondary filter membrane area of mouth of pipe setting is simultaneously less, and the price of secondary filter film own is high, which reduces production cost.
Above-described embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, patent of the present invention and protection domain should be as the criterion with appended claims.
