Detailed Description
The present invention will be described in further detail below with reference to the accompanying drawings by way of specific embodiments.
A disposable automatic exhaust liquid-stop infusion apparatus as shown in the figure comprises a puncture outfit 1, an upper infusion tube 2, a dropping funnel 3, a lower infusion tube, a flow regulator 5, an outer conical joint 6, a capillary infusion tube 7 and an intravenous injection needle 8 which are connected in sequence, wherein a flow guide column 9 is arranged in the dropping funnel 3, the height of the flow guide column 9 is 2/3 of the height of the dropping funnel 3, a flow guide channel 10 which is communicated up and down is arranged in the flow guide column 9, the flow guide channel 10 is respectively communicated with the dropping funnel 3 and the lower infusion tube, a flow baffle plate 11 is arranged above the flow guide column 9, the longitudinal section of the flow baffle plate 11 is of an arc-shaped structure, the flow baffle plate 11 is connected with the top of the flow guide column 9 through a plurality of connecting rods 12, a micro-flow guide hole 13 is arranged at the lower part.
The lower infusion tube is provided with a drug solution filter 14, and the drug solution filter 14 comprises a shell 1401. The inside liquid medicine filtration membrane 1402 that is equipped with vertical distribution of shell 1401, liquid medicine filtration membrane 1402 separates into first chamber 1403, second chamber 1404 with liquid medicine filter 14, and first chamber 1403 is equipped with at least one gas vent 1405, and fixedly connected with waterproof ventilated membrane 1406 in the gas vent 1405, first chamber 1403 top, second chamber 1404 bottom all with lower transfer line intercommunication.
The lower infusion tube comprises a first lower infusion tube 401 and a second lower infusion tube 402; the top of the first chamber 1403 is communicated with the first lower infusion tube 401 through a first joint 1407, and the top of the first lower infusion tube 401 is communicated with the diversion channel 10; the bottom of the second chamber 1404 communicates with the second lower infusion tube 402 through a second connector 1408.
Wherein, the inner wall of the shell 1401 is fixedly connected with a supporting part 15, and the supporting part 15 is fixedly connected with the liquid medicine filtering membrane 1402. The supporting portion 15 includes a fixing ring 1501 fixedly connected to the inner wall of the outer shell 1401, and a plurality of supporting rods 1502 arranged in a staggered manner are fixedly connected to the inside of the fixing ring 1501. The support portion 15 may provide support for the liquid medicine filtering membrane 1402, so as to prevent the liquid medicine filtering membrane 1402 from deforming or even breaking.
The chemical liquid filtration membrane 1402 is a polyethersulfone membrane having a pore diameter of 5 μm. The waterproof breathable membrane 1406 is a polytetrafluoroethylene membrane with a pore size of 0.2 μm.
In addition, a rubber seal plug 16 is provided in the exhaust port 1405 to be fitted to the exhaust port 1405. Before the infusion apparatus is unsealed and used, the rubber sealing plug 16 blocks the exhaust port 1405, so that the exhaust gas path is prevented from being blocked due to the fact that external foreign matters enter the exhaust port 1405 before the infusion apparatus is used.
The utility model discloses when concrete implementation: the rubber sealing plug 16 is pulled out, the puncture outfit 1 is connected with an infusion bottle, liquid medicine enters the dropping funnel 3 through the puncture outfit 1 and the upper infusion tube 2, the liquid medicine falls on the flow baffle plate 11 and falls into the dropping funnel 3 along the flow baffle plate 11, the liquid medicine is gathered at the lower part of the dropping funnel 3, and along with the rise of the liquid level, gas is continuously discharged from the flow guide channel 10 to the lower infusion tube. When the liquid level rises to be level with the top of the flow guide column 9, the liquid medicine flows into the first chamber 1403 through the flow guide channel 10, the liquid medicine wets the liquid medicine filtering membrane 1402, the liquid medicine adsorbed in membrane holes of the liquid medicine filtering membrane 1402 forms tension, air is prevented from entering the second chamber 1404, and when the liquid medicine is accumulated and rises to a sufficiently large pressure in the first chamber 1403, the liquid medicine enters the second chamber 1404 through the liquid medicine filtering membrane 1402, and the liquid medicine flows into the lower infusion tube again and is conveyed to the intravenous injection needle 8. After the liquid medicine in the infusion bottle is dripped, the residual liquid medicine is intercepted under the tension action of the liquid medicine filtering membrane 1402, so that the liquid stopping is realized. At this time, the residual liquid medicine still remains in the dropping funnel 3, and flows into the lower infusion tube through the micro-flow diversion hole 13, and because the aperture of the micro-flow diversion hole 13 is small, the residual liquid medicine flows into the lower infusion tube at an extremely slow speed, so that a small amount of liquid medicine flows within a period of time after liquid stopping, and the blood coagulation phenomenon caused by the liquid stopping at the intravenous injection needle 8 is avoided.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
