Abstract
The utility model discloses a heparin pump, which comprises a heparin cap having a front liquid feeding passage and a rear rubber cushion, a butterfly clack membrane provided on the inner wall of the liquid feeding passage and having the size gradually decreasing from the rear portion to the front portion, and a liquid storage cavity formed between the butterfly clack membrane and the rubber cushion, wherein a line seam is provided on the front end face of the butterfly clack membrane. The utility model has convenient operation, and can continuously feed liquid when an injector is extracted without blood backflow, thereby obviating thrombosis.
Description
Technical field
This utility model relates to a kind of heparin pump.
Background technology
Remaining needle uses the back first if need to keep somewhere, and must connect the auxiliary products calparine cap on its connector, injects a certain proportion of heparin in calparine cap, and anti-hemostasis-coagulation is kept somewhere to realize tube sealing.But heparin injects the back syringe when extracting, and can produce negative pressure and blood back, and form thrombosis, prevent the generation of blood back, just must be when the withdraw of the needle while moving back feed liquor, require the nurse to have behaviour's experience of relatively enriching, otherwise, be difficult to obtain satisfied effect.
Summary of the invention
This utility model purpose is: a kind of heparin pump is provided, and this heparin pump is easy to operate, can also continue feed liquor when syringe is extracted, can blood back, avoided the formation of thrombosis.
The technical solution of the utility model is: a kind of heparin pump, comprise that the front portion has the calparine cap that feed pathway, rear portion have rubber cushion, the inwall of described feed pathway be provided with one by after the butterfly valve that closes up gradually forward, be formed with liquid storage cylinder between butterfly valve and the rubber cushion, the front end face of butterfly valve is provided with wire and cracks.
The further technical scheme of this utility model is: a kind of heparin pump, comprise that the front portion has the calparine cap that feed pathway, rear portion have rubber cushion, the inwall of described feed pathway be provided with one by after the butterfly valve that closes up gradually forward, be formed with liquid storage cylinder between butterfly valve and the rubber cushion, the front end face of butterfly valve is provided with wire and cracks; Described calparine cap is provided with the air bag that is communicated with liquid storage cylinder outward.
The more detailed technical scheme of this utility model is: a kind of heparin pump, comprise that the front portion has the calparine cap that feed pathway, rear portion have rubber cushion, the inwall of described feed pathway be provided with one by after the butterfly valve that closes up gradually forward, be formed with liquid storage cylinder between butterfly valve and the rubber cushion, the front end face of butterfly valve is provided with wire and cracks; Described calparine cap is provided with the air bag that is communicated with liquid storage cylinder outward; The rear port of described butterfly valve is rounded, and the front end face of butterfly valve is Long Circle.
This utility model advantage is:
This utility model be provided with on the inwall of feed pathway one by after the butterfly valve that closes up gradually forward, the front end face of butterfly valve is provided with wire and cracks, when syringe injected liquid storage cylinder with liquid, the pressurized that cracks of butterfly valve opened, and liquid is entered; When the syringe needle of syringe is extracted, owing in the liquid storage cylinder liquid is housed also, so liquid also can continue to flow into, and occurs blood back when having avoided the withdraw of the needle, avoided the formation of thrombosis.
2. butterfly valve of the present utility model by after close up gradually forward, and the rear port of butterfly valve is rounded, the front end face of butterfly valve is Long Circle, when this just helped injecting liquid, the pressurized that cracks opened, and had realized the liquid way flow.
3. this utility model is provided with the air bag that is communicated with liquid storage cylinder outside calparine cap, when to the liquid storage cylinder fluid injection, part liquid can flow into air bag, during the withdraw of the needle, meet as long as just can make liquid continue to flow into to open by lower gasbag gently, continue feed liquor when having realized the withdraw of the needle better, further avoided the formation of thrombosis.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further described:
Structural representation when Fig. 1 does not have air bag for this utility model;
Structural representation when Fig. 2 has air bag for this utility model.
Wherein: 1 feed pathway; 2 rubber cushions; 3 calparine caps; 4 butterfly valves; 5 liquid storage cylinders; 6 air bags.
The specific embodiment
Embodiment: as depicted in figs. 1 and 2, a kind of heparin pump, comprise that the front portion has the calparine cap 3 that feed pathway 1, rear portion have rubber cushion 2, the inwall of feed pathway 1 be provided with one by after the butterfly valve 4 that closes up gradually forward, be formed with liquid storage cylinder 5 between butterfly valve 4 and the rubber cushion 2, the calparine cap 3 outer air bags 6 that are communicated with liquid storage cylinder 5 that are provided with; The rear port of butterfly valve 4 is rounded, and the front end face of butterfly valve 4 is Long Circle, and the front end face of butterfly valve 4 is provided with wire and cracks.
When syringe injected liquid storage cylinder 5 with liquid, the pressurized that cracks of butterfly valve 4 opened, and liquid is entered; When the syringe needle of syringe is extracted, can press lower gasbag 6 gently, liquid be continued to flow into open and meet, avoid the formation of thrombosis.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, this utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within this utility model scope required for protection.
