Embodiment 1

[0024] see figure 1 with figure 2 , a needle-type precision filter drug-dissolving syringe proposed in this embodiment includes a push rod 110, a first drug-dissolving tube 120, a drug-dissolving cavity 130, a second drug-dissolving tube 140, and an injection needle 150; the push rod 110 Movably installed in the first drug dissolving tube 120, the first drug dissolving tube 120 communicates with the drug dissolving cavity 130; the second drug dissolving tube 140 is provided with a main channel 141, a second drug dissolving tube 140 A secondary channel 142 and a second secondary channel 143; the first port of the main channel 141 communicates with the drug-dissolving chamber 130, and its second port communicates with the injection needle 150; the first port of the first secondary channel 142 The port communicates with the drug-dissolving cavity 130, and its second port merges with the main channel 141; the first port of the second secondary channel 143 communicates with the d...

Embodiment 2

[0037] see Figure 4 , this embodiment proposes another needle-type precision filter drug-dissolving syringe, which differs from the needle-type precision filter drug-dissolving syringe in the above-mentioned embodiment 1 only in that the first drug-dissolving syringe in embodiment 2 is opposite to that of embodiment 1. Tube 120 made another design, formed as Figure 4 The first drug dissolving tube 220 is shown. In the first embodiment, the first drug-dissolving tube 120 and the drug-dissolving cavity 130 are preferably integrally formed; while in the second embodiment, the first drug-dissolving tube 220 and the drug-dissolving cavity 230 are a detachable combination, further Furthermore, the first drug dissolving tube 220 can also be used as a syringe barrel of a common syringe in the prior art, and it can be installed on the drug dissolving cavity 230 to filter the drug solution when extracting and injecting the drug solution.

[0038] Specifically, the needle-type precis...

Abstract

The invention relates to a needle type precise filtering and medicine dissolving syringe. A main channel, a first auxiliary channel and a second auxiliary channel are arranged in a second medicine dissolving pipe, a first port of the main channel is communicated with a medicine dissolving cavity, a second port of the main channel is communicated with an injection needle, a first port of the first auxiliary channel is communicated with the medicine dissolving cavity, a second port of the first auxiliary channel intersects with the main channel, a first port of the second auxiliary channel is communicated with the medicine dissolving cavity, a second port of the second auxiliary channel intersects with the main channel , a main one-way valve block is installed on the first port of the main channel, a first auxiliary one-way valve block is installed on the second port of the first auxiliary channel, a second auxiliary one-way valve block is installed on the second port of the second auxiliary channel, and the interior of the medicine dissolving cavity is provided with a precise filtering film which can separate the interior of the medicine dissolving cavity from the space from the first port of the main channel to the first port of the first auxiliary channel and the first port of the second auxiliary channel.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a needle-type precision filter drug-dissolving syringe capable of filtering drug liquid. Background technique [0002] At present, most of the medicines used clinically are packaged in glass bottles. When the rubber stopper of the glass bottle is pierced with the needle of a syringe or the glass bottle is cut with a grinding wheel to extract the medicine, particles such as bottle stopper chips or glass powder are easily mixed into the medicine; In addition, due to improper artificial preservation or misoperation, it is also easy to cause insoluble particles in the liquid medicine. And because ordinary syringes do not have the filtering function, these particles will be injected into the patient's body together with the liquid medicine, causing various injuries to the patient's body. In mild cases, it may induce venous inflammation and other diseases, and in severe cases...
