Abstract
The invention discloses a double-layer gas-phase membrane structure of a precise liquid medicine filter. The double-layer gas-phase membrane structure comprises a liquid medicine filter, wherein a ventilating window of the liquid medicine filter is of an inner sleeve ring structure, i.e., double steps are arranged at the position of the ventilating window; a layer of gas-phase membrane is welded on an elliptical ring with a raised inner ring; two layers of gas-phase membranes are welded on an elliptical ring with a raised outer ring. According to the double-layer gas-phase membrane structure of the precise liquid medicine filter, disclosed by the invention, the ventilating window of the precise liquid medicine filter is designed into a double-step structure, and two layers of gas-phase membranes are welded, so that the security of the ventilating window is enhanced, a liquid leakage problem during a transfusion process is effectively reduced, and a non-qualified rate of liquid leakage is reduced to one millionth from one thousandth in the past; the area of the gas-phase membranes is increased, the air permeability of the gas-phase membranes is enhanced, and the reduction of the air permeability cannot be caused by the double-layer gas-phase membranes. A method of the double-layer gas-phase membrane structure is suitable for improving all precise liquid medicine filters in the market.
Description
Technical field
The present invention relates to a kind of double-deck gas phase membrane structure and welding method thereof of precision liquid medicine filter, belong to technical field of medical instruments.
Background technology
Along with the raising of Chinese medical level, the use of single use precision infusion set is more and more universal, and the output of its critical component single use precision liquid medicine filter is also increasing.
At present, there is serious problem in the gas phase membrane safety aspect of precision liquid medicine filter, and the monolayer gas phase membrane phenomenon of leakage is serious, has a strong impact on infusion safety.Gas phase membrane is the weakest position that liquid medicine filter is isolated from the outside, the safety in utilization of its firm, complete degree direct influence product.Because not prison welding is solid and the factor such as medicine corrosion, the phenomenon of leakage happens occasionally, and causes infusing unsuccessfully, all causes damage to patient and hospital, aggravates conflict between doctors and patients.
Summary of the invention
The object of the present invention is to provide one can overcome above-mentioned defect, structure and the welding method of precision liquid medicine filter dependability can be promoted.
The double-deck gas phase membrane structure of precision liquid medicine filter of the present invention, comprise liquid medicine filter, the transom place of liquid medicine filter is inner sleeve structure, namely transom place arranges double step, weld one deck gas phase membrane at the elliptical ring place of inner ring projection, weld two layers of gas phase membrane at the elliptical ring place of outer ring projection.
Two layers of described gas phase membrane area are 1.5-2.5 times of one deck gas phase membrane area.
A welding method for the double-deck gas phase membrane structure of above-mentioned precision liquid medicine filter, by needing the upper casing welding gas phase membrane to put into welding tooling, being installed one deck gas phase membrane, being welded by ultrasonic welding machine; After the rear inspection of welding is errorless, the upper casing being welded with one deck gas phase membrane is put into welding tooling, secondary gas phase membrane is installed, is welded by ultrasonic welding machine.
The present invention compared with prior art, has following beneficial effect:
The transom of precision liquid medicine filter is designed to double step structure, welds two-layer gas phase membrane, strengthen its safety, effectively reduce the leakage problem in infusion process, the disqualification rate of leakage by original one thousandth be reduced to 1,000,000/.Increase gas phase membrane area, strengthen its aeration, venting capability will be caused to decline because of double-deck gas phase membrane.Its method is applicable to the improvement of all precision liquid medicine filters on the market.

Fig. 2 is the main TV structure schematic diagram of the present invention;
In figure: 1, upper casing; 2, two layers of gas phase membrane; 3, one deck gas phase membrane; 4, the elliptical ring of inner ring projection; 5, the elliptical ring of outer ring projection.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated:
The double-deck gas phase membrane structure of precision liquid medicine filter as shown in Figure 1, comprise liquid medicine filter, the transom place of liquid medicine filter is inner sleeve structure, namely transom place arranges double step, weld one deck gas phase membrane 3 at elliptical ring 4 place of inner ring projection, weld two layers of gas phase membrane 2 at elliptical ring 5 place of outer ring projection.Two layers of gas phase membrane 2 area is 1.8 times of one deck gas phase membrane 3 area.
When welding by needing the upper casing welding gas phase membrane to put into welding tooling, one deck gas phase membrane 3 being installed, being welded by ultrasonic welding machine; After the rear inspection of welding is errorless, the upper casing being welded with one deck gas phase membrane 3 is put into welding tooling, secondary gas phase membrane 2 is installed, is welded by ultrasonic welding machine.
