Description
Technical field
This utility model relates to a kind of medical Transfusion device additional device, specifically a kind of transfusion one-way valve.
Background technology
At present, disposable infusion set is widely used in venous transfusion.At changing position, the arm of raising one's hand, when walking about, may make transfusion position higher than dropping funnel liquid level, blood back can appear as patient; During higher than infusion pressure, also blood back can appear as the human pressure; When nursing staff's Comparision is busy, if having little time to close tube for transfusion, blood back appears easily also; This has caused the feared state of mind not only for the patient to a certain extent, and long-time blood back, can cause blood vessel embolism, and is very dangerous.Because transfusion device small volume, cost are low, higher to the requirement of check valve, so up to now, disposable transfusion device does not still have the return blood function.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of structure reasonable, easy to use, reliable, has the return blood function, improves the transfusion one-way valve of infusion safety.
the technical scheme in the invention for solving the above technical problem is: a kind of transfusion one-way valve, it comprises upper shell, lower house, latex balloon, spring, it is characterized in that: described upper shell and lower house are respectively equipped with infusion channel, the lower house upper surface is provided with the supporting clapboard with manhole, lower house and upper shell are gluing fixedly to be integral, intermediate formation one conical cavity, described latex balloon and spring fitting are in conical cavity, the spring bottom is fixed on the supporting clapboard of lower house, apical support is positioned at the latex balloon on conical cavity top, the latex balloon shutoff is below the infusion channel outlet of upper shell.
Described lower house supporting clapboard is circular, and several manholes evenly distribute on it.Manhole is communicated with the infusion channel of upper shell and lower house.
Described lower house supporting clapboard center is provided with a projection that is fixed with the spring bottom.
Described lower house is provided with tapped female Luer.Female Luer communicates with the infusion channel of lower house, be used for to connect the normal component in transfusion downstream, as the remaining needle joint etc.
Described upper shell is provided with the pipe joint with infusion channel.Be used for to connect the transfusion device upstream, as dropping funnel etc.Conical cavity is communicated with the infusion channel of this pipe joint.
When this utility model uses, the normal infusion process, latex balloon overcomes spring supporting under the pressure of top circulating liquid, to bottom offset, open infusion channel, and liquid flows to female Luer by the upper shell infusion channel.When transfusion end or other abnormal condition, the resilient support of spring makes latex balloon get back to original position, blocks the infusion channel of upper shell, and the infusion channel blocking-up like this, has just realized the one-way flow of liquid.Against existing technologies, this utility model structure rationally, and is easy to use, reliable, has the return blood function, improved infusion safety.It is a kind of desirable transfusion one-way valve.This utility model is applicable to be arranged on medical Transfusion device, guarantees the one-way flow of transfusion, blood transfusion.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is composition structural representation of the present utility model.
1. lower houses in figure, 2. upper shell, 3. latex balloon, 4. spring, 11. female Luer, 12. infusion channel, 13. supporting clapboards, 131. manholes, 132. projections, 21. conical cavities, 22. infusion channel.
The specific embodiment
As can be seen from Figure 1, a kind of transfusion one-way valve, it comprises upper shell 2, lower house 1, latex balloon 3, spring 4 etc.Described upper shell 2 and lower house 1 are respectively equipped with infusion channel 22 and infusion channel 12, and lower house 1 upper surface is provided with the supporting clapboard 13 with manhole 131.Lower house 1 and upper shell 2 stick with glue that agent is gluing fixedly to be integral, intermediate formation one conical cavity 21.Conical cavity 21 is communicated with infusion channel 22.Manhole 131 is communicated with the infusion channel 22 and 12 of upper shells and lower house, like this, just forms a passage that can circulate medicinal liquid between lower house 1 and upper shell 2.
Characteristics of the present utility model are: described latex balloon 3 and spring 4 are arranged in conical cavity 21, spring 4 bottoms are fixed on the supporting clapboard 13 of lower house 1, the top connects supports the latex balloon 3 that is positioned at conical cavity 21 tops, and latex balloon 3 shutoff are below infusion channel 22 outlets of upper shell.
Described lower house 1 supporting clapboard 13 is circular, and several manholes 131 evenly distribute on it.Manhole 131 is communicated with infusion channel 22 and the infusion channel 12 of upper shell and lower house.
Described lower house 1 supporting clapboard 13 centers are provided with a projection 132 that is fixed with spring 4 bottoms.
Described lower house 1 is provided with tapped female Luer 11.Female Luer 11 communicates with the infusion channel 12 of lower house, be used for to connect the normal component in transfusion downstream, as the remaining needle joint etc.
Described upper shell 2 is provided with the pipe joint with infusion channel 22.Be used for to connect the transfusion device upstream, as dropping funnel etc.Conical cavity is communicated with the infusion channel of this pipe joint.
When this utility model uses, the normal infusion process, latex balloon 3 overcomes the support of spring 4 under the pressure of top circulating liquid, to bottom offset, open infusion channel 22, and liquid flows to female Luer 11 by upper shell infusion channel 22.When transfusion end or other abnormal condition, the resilient support of spring 4 makes latex balloon 3 get back to original position, blocks the infusion channel 22 of upper shell, and the infusion channel blocking-up like this, has just realized the one-way flow of liquid.
This utility model structure rationally, and is easy to use, reliable, has the return blood function, improved infusion safety.It is a kind of desirable transfusion one-way valve.This utility model is applicable to be arranged on medical Transfusion device, guarantees the one-way flow of transfusion, blood transfusion.
