Abstract
The utility model relates to a novel transfusion device. An inflating ball (2), a non-return stop valve (3), a gas bag (4), a three-way joint (5), a pressure gauge (6), a pressure limiting valve (7) and a needle head are orderly connected in the existing pressure transfusion device shell (1) by a pipe, an air filter (8) is added in a flow path, and is additionally provided with a liquid level warning device. Thus, air which enters a transfusion bottle can be disinfected and purified. The utility model has the advantages of more simple and convenient operation and safety, and the utility model is widely suitable for emergency treatment transfusion of hospitals and fields.
Description
This utility model relates to a kind of pressure-type infusion set, relates in particular to a kind of transfusion device with gas pressure.
(patent No.: 94239738.X) disclose a kind of pressure transfusion device, it mainly constructs and is Chinese patent, inflates ball, non-return stop valve, airbag, three way cock, air gauge, valve, syringe needle order conduit in the housing to connect.Its weak point is, the air non-sterile that enters in the infusion bottle is filtered, and liquid is totally lost and can not be reported to the police automatically, and the pipe of the Mo Shi on the disposable transfusion device is unstable, is difficult for observing transfusion speed.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of safer, easier, bottled and packed novel transfusion device that can both use of operation is provided.
The purpose of this utility model is achieved in that in housing (1), inflating ball (2), non-return stop valve (3), airbag (4), three way cock (5), Pressure gauge (6), pressure limiting valve (7), syringe needle (9) order pipeline connects, and spring (17) is pushed down airbag (4) by pressing plate (16).Between pressure limiting valve (7) and syringe needle (9) pipeline, add and be connected into an air filter (8).A side is provided with funnel-form bottle stand (13), annular Mo Shi pipe support (14), rubber band (15) and hook (18) outside housing (1).Liquid level alarm (10), display lamp (11) also are set in housing (1).The emission of liquid level alarm (10), receiving tube (12) place the bottle stand upper port.Adopt air filter, the air that enters infusion bottle is purified.When below the liquid level in the infusion bottle drops to liquid level alarm emission, receiving tube position, liquid level alarm sends the sound and light alarm signal.
Because adopt such scheme, it is safer to infuse, more convenient operation.Only increase air and liquid level alarm, construct also simple.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is that this utility model is analysed and observe organigram.
Fig. 2 be the A of Fig. 1 to view, signal bottle stand shape.
Fig. 3 be the B of Fig. 1 to view, signal Mo Shi pipe support shape.
Among the figure 1, housing 2, inflate ball 3, non-return stop valve 4, airbag 5, three way cock 6, Pressure gauge 7, pressure limiting valve 8, air filter 9, syringe needle 10, liquid level alarm 11, display lamp 12, the receiving tube 14 of making a good deal of money, Mo Shi pipe support 15, rubber band 16, pressing plate 17, spring 18, hook 19, spongy body
In Fig. 1, a kind of novel transfusion device, in housing (1), inflating ball (2), non-return stop valve (3), airbag (4) three way cock (5), Pressure gauge (6), pressure limiting valve (7), air filter (8), syringe needle (9) order pipeline connects, and spring (17) is pushed down airbag (4) by pressing plate (16).A side is provided with funnel-form bottle stand (13) (as shown in Figure 2), annular Mo Shi pipe support (14) (as shown in Figure 3), rubber band (15) and hook (18) outside housing (1).Funnel-form bottle stand and rubber band make glass infusion bottle more firm fixed, and hook extension plastic infusion bag is very convenient.Annular Mo Shi pipe support makes the Mo Shi pipe location on the disposable transfusion device, is convenient to observe transfusion speed.Liquid level alarm (10), display lamp (11) also are set in housing (1), and the emission of liquid level alarm (10), receiving tube (12) place bottle stand (13) upper port.Air filter (8) is a doleiform, the inlet in the bottom, the outlet on spongy body (19), in ethanol (20) is arranged.
Claims (2)
1, a kind of novel transfusion device, in housing (1), inflating ball (2), non-return stop valve (3), airbag (4), three way cock (5), Pressure gauge (6), pressure limiting valve (7), syringe needle (9) order pipeline connects, spring (17) is pushed down airbag (4) by pressing plate (16), it is characterized in that: add between pressure limiting valve (7) and syringe needle (9) pipeline and be connected into an air filter (8); A side is provided with funnel-form bottle stand (13), annular Mo Shi pipe support (14), rubber band (15) and hook (18) outside housing (1); Liquid level alarm (10), display lamp (11) also are set in housing (1); The emission of liquid level alarm (10), receiving tube (12) place bottle stand (13) upper port.
2, transfusion device according to claim 1 is characterized in that: air filter (8) is a doleiform, the inlet in the bottom, the outlet on spongy body (19), in ethanol (20) is arranged.
