Description
Technical field
This utility model relates to a kind of transfusion device, relates in particular to the accurate film of a kind of Anti-bubble and stops liquid transfusion device.
Background technology
At present, the transfusion device of market is varied, and people, in the time 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 wants defeated to the greatest extent time, just transfusion needle need to be extracted from human body, will be caused " blood back " phenomenon if do not extract, like this patient body be had to very large harm.
Utility model content
This utility model, in order to solve the above-mentioned deficiency of prior art, has proposed the accurate film of a kind of Anti-bubble and has stopped liquid transfusion device.
In order to solve the problems of the technologies described above, this utility model 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: on described tube for transfusion, be also provided with the accurate film of an Anti-bubble and stop liquid device, the accurate film of this Anti-bubble stops liquid device and comprises by fore shell and back cover and coordinate the circular housing forming, 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 on back cover shell wall, is laterally provided with correspondence and is arranged on the waterwall of water inlet pipe below; Described fore shell shell wall is provided with to coordinate and holds out against overboard wall in waterwall, and overboard wall is provided with multiple water falling holes, and between described waterwall and overboard wall, fixes a filter membrane by sealing circular housing interior separation is become to two accommodation spaces; One secondary filter film is installed on the upper end mouth of pipe of described outlet pipe.
Further, described fore shell shell wall is provided with multiple steam vents, 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, inner tube does not adopt and makes containing DEHP plasticizer material, and outer tube adopts PVC material to make.
Compared with prior art, it is ingenious that the accurate film of Anti-bubble that this utility model adopts stops liquid device design, circular housing is separated into two accommodation spaces by the filter membrane arranging 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 one side, the generation of bubble so just can prevent from infusing time, 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 be in the time that transfusion finishes soon, prevent medicinal liquid adverse current, this device has reduced the use of secondary filter film, save greatly cost, be worth significantly promoting.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side cross-sectional views that the accurate film of Anti-bubble of the present utility model stops liquid device;
Fig. 3 is the axonometric chart that the accurate film of Anti-bubble of the present utility model stops liquid device.
Detailed description of the invention
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, 2, 3, the accurate film of Anti-bubble the utility model 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, inner tube does not adopt and makes containing DEHP plasticizer material, and outer tube adopts PVC material to make.
On tube for transfusion 1, be also provided with the accurate film of an Anti-bubble and stop liquid device, the accurate film of this Anti-bubble stops liquid device and comprises by fore shell 8 and back cover 9 and coordinate the circular housing 7 forming, and circular housing 7 inside are 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 on back cover shell wall, is laterally provided with correspondence and is arranged on the waterwall 93 of water inlet pipe 91 belows; Fore shell 8 shell walls are provided with and coordinate the overboard wall 81 holding out against in waterwall 93, overboard wall is provided with multiple water falling holes, and between waterwall 93 and overboard wall 81, fix a filter membrane 10 by sealing circular housing 7 interior separations are become to two accommodation spaces, fore shell 8 shell walls are provided with multiple steam vents 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; One secondary filter film 94 is installed on the upper end mouth of pipe of outlet pipe 92.
In the time 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 in filter membrane 10 left sides, in this accommodation space, can act on by steam vent 82 and breathing waterproof film 83, carry out pump-down process, the accommodation space to opposite side through filter membrane 10 again, now in medicinal liquid, impurity is blocked and cannot passes through filter membrane, filter membrane 10 is common filter membrane, cheap, cost is low, the medicinal liquid that now enters into another accommodation space slowly overflows the outlet pipe of mouth of pipe certain altitude, flow out from outlet pipe again, now need to filter through the secondary filter film 94 on the mouth of pipe, secondary filter film 94 can be thoroughly by the contaminant filter in medicinal liquid, secondary filter film is by hydrophilic, while touching medicinal liquid, micropore on secondary filter film opens, medicinal liquid is dirty, in the time that transfusion will finish, 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 the interior liquid level of outlet pipe cannot continue to decline, stop transfusion, preventing " blood back " phenomenon produces.
In this utility model, the mouth of pipe of outlet pipe is provided with certain altitude, has prevented like this generation of bubble, and can allow get off through the contamination precipitation of filter membrane 10, the secondary filter membrane area that the mouth of pipe arranges is simultaneously less, and the price of secondary filter film own is high, has so just reduced production cost.
Above-described embodiment has only been expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, this utility model patent and protection domain should be as the criterion with appended claims.
