Description

Technical Field

[0001] This utility model is an intravenous infusion set with drug filtration effect, belonging to the field of medical equipment technology. Background Technology

[0002] Intravenous infusion sets are a widely used intravenous infusion device in clinical practice. There are two types of existing intravenous infusion sets: one is an intravenous infusion set with a venting tube that is inserted into an infusion glass bottle, and the other is an intravenous infusion set without a venting tube that is inserted into an infusion bag. The vast majority of intravenous infusion sets have a filtration function.

[0003] Chinese patent number CN203619994U mentions a filtering infusion set that achieves better filtration through a coarse filtration and a fine filtration, with the fine filtration having a large filtration area that does not affect the infusion flow rate and velocity. The venting function further enhances the filtration process. It is also simple in structure and low in cost. However, this device often requires the use of an infusion heater in winter to raise the temperature of the medication to a suitable level, which increases the operating cost for small clinics, making it less economical. There is an urgent need for an intravenous infusion set with medication filtration capabilities to address these issues. Utility Model Content

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-7 This utility model provides a technical solution: an intravenous infusion set with drug filtration effect, comprising a first tube body 1, an outer insulating cylinder 5, and an insulating mounting shell 6. An inner insulating cylinder 12 is installed on the bottom surface of the outer insulating cylinder 5. A second through groove 13 is opened on the bottom surface of the outer insulating cylinder 5, communicating with the inner insulating cylinder 12. A cover plate 9 is installed on the top of the outer insulating cylinder 5. A first through groove 8 is opened in the middle of the top of the cover plate 9, communicating with the inner insulating cylinder 12. An inlet pipe 10 is installed on the top of the cover plate 9. An outlet pipe 11 is installed on the bottom surface of the outer insulating cylinder 5. The outer insulating cylinder 5 and the inner insulating cylinder 12 are connected. An inner cavity is formed between the warm cylinders 12, and the inlet pipe 10 and outlet pipe 11 are respectively connected to the inner cavity. An inner ring 14 is installed above the heat-insulating mounting shell 6, and a circular groove 15 is opened through the middle of the inner ring 14. A precision filter 17, a filter membrane 18 and a filter screen 19 are installed in the heat-insulating mounting shell 6 from top to bottom. A bottle stopper inserter 4 is connected to the upper end of the first tube 1. The lower end of the heat-insulating mounting shell 6 is a conical design. This design solves the problem that the original device often needs to use an infusion heater in winter to raise the temperature of the medicine solution to a suitable value, which increases the cost of use for small clinics and is generally not economical.

[0023] As the first embodiment of this utility model: a roller speed regulator 3 is connected to the lower side of the upper end of the first tube 1, and a dripping bucket 2 is integrally formed in the middle of the first tube 1. By setting the roller speed regulator 3, it is convenient to adjust the delivery speed of the medicine liquid. The lower end of the first tube 1 is inserted into the first through groove 8, penetrating the inner insulation cylinder 12, and the lower end of the first tube 1 extends out from the second through groove 13. The tube wall of the first tube 1 is in contact with the inner wall of the inner insulation cylinder 12. By inserting the first tube 1 into the inner insulation cylinder 12, heat can be transferred to the first tube 1 through the side wall of the inner insulation cylinder 12 using the principle of heat transfer. The circular groove 15 is sealed to the lower end of the first tube 1. The second tube 16 is sealed to the lower part of the insulation mounting shell 6. The lower end of the second tube 16 is fitted with a needle 7. The filter membrane 18 is a nucleoporous membrane with a double-layer filter medium. The advantages of using a nucleoporous membrane with a double-layer filter medium are that it has strong dirt holding capacity, regular and uniform filter pores, high filtration accuracy, no foreign matter shedding, and low drug adsorption.

[0024] As a second embodiment of this utility model: In use, the outlet pipe 11 is first blocked by the external sealing plug, and then hot water at a suitable temperature is added to the inner cavity formed by the inner insulation cylinder 12 and the outer insulation cylinder 5 through the inlet pipe 10. Then, the bottle stopper inserter 4 is inserted into the outer bottle stopper, and the medicine will flow along the first tube 1. The flow speed of the medicine is adjusted by the roller speed regulator 3. When the medicine reaches the outer insulation cylinder 5, the inner wall of the inner insulation cylinder 12 will transfer heat to the wall of the first tube 1, and then to the medicine, causing its temperature to rise to a certain extent. Then the medicine will enter the insulation installation shell 6. Under the action of the precision filter 17, the filter membrane 18 and the filter screen 19, the medicine will be filtered and then enter the patient's blood vessel through the second tube 16 and the needle 7.
