Description

Transfusion system

Technical Field

The utility model relates to the field of medical equipment, in particular to an infusion apparatus.

Background

The infusion apparatus is a common medical consumable, and a channel between a vein and liquid medicine is established through aseptic treatment for intravenous infusion. Generally, the infusion apparatus is formed by connecting eight parts, namely a vein needle or an injection needle, a needle head protective cap, an infusion hose, a liquid medicine filter, a flow rate regulator, a drip cup, a bottle stopper puncture outfit, an air filter and the like, and a part of the infusion apparatus also comprises an injection piece, a medicine adding port and the like. GB8368-2018 'Disposable transfusion system gravity infusion formula' stipulates that a transfusion system adopts a bottle stopper puncture outfit, but the existing transfusion system adopts the bottle stopper puncture outfit, the bottle stopper puncture outfit has large size, and tiny rubber particles are easily generated in the process of puncturing a transfusion bag during dispensing and transfusion, so that the medicine delivery safety is influenced.

Disclosure of Invention

The utility model discloses a solve present transfusion system and produce tiny rubber granule easily when dispensing, infusing repeatedly the puncture in-process, influence the technical problem of infusion safety, provide a transfusion system that puncture procedure is few.

The utility model provides a transfusion system, it is equipped with venous transfusion needle, liquid medicine filter, hose, velocity of flow regulator and Murphy's burette, and venous transfusion needle, liquid medicine filter and Murphy's burette pass through the hose intercommunication, and the velocity of flow regulator is installed on the hose, still is equipped with the connector through threaded connection.

Preferably, the connection port is an externally threaded connection port.

Preferably, a connecting pipe is arranged outside the connecting port, and internal threads are arranged on the connecting pipe along the inner edge of the pipe wall.

The utility model has the advantages that: during the infusion process, only puncture is needed during the first dispensing, and no puncture is needed during the later dosing or the infusion process, so that the generation of rubber particles is effectively reduced, and the infusion safety is ensured; the infusion apparatus is connected with the infusion bottle through threads, so that the connection is convenient and fast, the connection reliability is effectively guaranteed, and the possibility of pollution is reduced.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, so that those skilled in the art can easily implement the present invention.

Example 1: as shown in fig. 1-2, the present embodiment includes an intravenous infusion needle 1, a medical liquid filter 2, a lower hose 3, a murphy's dropper 4, a flow rate regulator 5, an upper hose 6 and an internal thread connector 8, the intravenous infusion needle 1 is communicated with the medical liquid filter 2, the medical liquid filter 2 is communicated with the murphy's dropper 4 through the lower hose 3, the murphy's dropper 4 is communicated with the internal thread connector 8 through the upper hose 6, and the lower hose 3 is further provided with the flow rate regulator 5 for regulating the flow rate of the medical liquid; an inner transfusion port 81 is arranged on the internal thread connecting port 8 and communicated with the upper hose 6, a connecting pipe 82 is arranged on the outer ring of the inner transfusion port 81, and an internal thread 83 is arranged on the connecting pipe 82 along the inner edge of the pipe wall.

As shown in fig. 3, the infusion needle is provided with a connecting pipe 10 and a needle 12, the outer periphery of the connecting pipe 10 is provided with a connecting pipe external thread 11, and the infusion needle with the external thread can be matched through an internal thread 83 to complete the whole infusion operation; the infusion needle is inserted into the infusion bottle in the dispensing process before infusion and is reliably fixed by the corresponding clamping device; when infusion is needed, the infusion operation can be completed only by inserting the embodiment into the needle head with the external thread and screwing the embodiment to firmly fix the embodiment and the needle head.

Example 2: as shown in fig. 4, the present embodiment includes an intravenous infusion needle 1, a liquid medicine filter 2, a lower hose 3, a murphy's dropper 4, a flow rate regulator 5, an upper hose 6 and an external thread connector 9, the intravenous infusion needle 1 is communicated with the liquid medicine filter 2, the liquid medicine filter 2 is communicated with the murphy's dropper 4 through the lower hose 3, the murphy's dropper 4 is communicated with the external thread connector 9 through the upper hose 6, and the lower hose 3 is further provided with the flow rate regulator 5 for regulating the flow rate of the liquid medicine; the external thread connecting port 9 is provided with an external infusion port 91 communicated with the upper hose 6, and the outer ring of the external infusion port 91 is provided with an external thread 92.

In the embodiment, the external thread 92 can be matched with a needle with an internal thread to complete the whole infusion operation; the main structure of the needle with the internal thread is that the lower end of the needle is provided with an infusion needle with a connecting pipe, the inner wall of the connecting pipe is provided with the internal thread, and the connection is completed by the internal thread and the external thread 92.
