Abstract
A backflow preventive transfusion apparatus belongs to medical appliances and mainly resolves the problem that a traditional transfusion apparatus is poor in service safety. The backflow preventive transfusion apparatus structurally comprises a needle and a transfusion tube, a backflow preventive card is arranged surrounding the inner wall of the transfusion tube on the upper portion of the needle, one end of the backflow preventive card is fixed on the inner wall of a hose, and the other end of the backflow preventive card is an open type inverted conical card. The service safety of the transfusion apparatus is increased, blood backflow during transfusion is effectively prevented and avoided, difficulty in nursing operation is reduced, and the backflow preventive transfusion apparatus is safe and convenient in use.
Description
Technical field
This utility model relates to a kind of transfusion device, specifically is a kind of anti-return transfusion device.
Background technology
Transfusion device is a kind of common disposable medical treatment consumptive materials process aseptic process, that set up passage between vein and the medicinal liquid that is mainly used in venous transfusion, is generally connected to form by intravenous needle, helmet, infusion tube, liquid medicine filter, flow regulator, a kettle, bottle plug puncture unit, air inlet pipe air filter.During use, under the atmospheric pressure effect, liquid flows into thinner infusion tube and forms water column in the bottle, when water column pressure during greater than venous pressure, liquid continuous in the bottle and stably flow into vein is to replenish body fluid, electrolyte or nutrient substance is provided, but because the unshielded effect of traditional infusion device, be totally lost the back as the untimely syringe needle that pulls out at liquid, cause blood to reflux easily, cause danger.
The utility model content
The purpose of this utility model is to provide a kind of anti-return transfusion device, and this transfusion device can effectively prevent and avoid the blood reflux problem in the infusion process, and is safe and convenient to use.
The technical scheme in the invention for solving the technical problem is: a kind of anti-return transfusion device, its structure comprises injection needle and tube for transfusion, tube for transfusion inner wall surrounding on injection needle top is provided with an anti-return card, described anti-return card one end is fixed on the hose inner wall, and the other end is open inverted cone card.
The beneficial effects of the utility model are: owing to be provided with an anti-return card in tube for transfusion inside, during use, the anti-return card is drawn close to the hose inner wall direction by the effect of medicinal liquid pressure, and hose passages is opened, and medicinal liquid flows through from the card place; After medicinal liquid had flowed, the pressure that acts on the card place disappeared, and two cards merge, and hose passages is dwindled, because card is inverted cone, the blood of backflow can't flow out by card; Improve safety in utilization, effectively prevented and avoided the blood backflow phenomenon in the infusion process, reduced the difficulty of nursery work, safe and convenient to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the local structure for amplifying sketch map among Fig. 1.
Among the figure: 1 injection needle, 2 tube for transfusions, 3 anti-return cards.
The specific embodiment
As shown in Figure 1 and Figure 2.A kind of anti-return transfusion device, its structure comprises injection needle 1 and tube for transfusion 2, tube for transfusion 2 inner wall surroundings on injection needle 1 top are provided with an anti-return card 3, described anti-return card 3 one ends are fixed on tube for transfusion 2 inwalls, the other end is open inverted cone card, and anti-return card 3 is an elastic material, can realize opening when medicinal liquid is flowed through, closed after medicinal liquid has flowed, anti-backflow.
During use, anti-return card 3 is drawn close to tube for transfusion 2 inwall directions by the effect of medicinal liquid pressure, tube for transfusion 2 passages are opened, medicinal liquid flows through from the opening part of anti-return card, and after medicinal liquid had flowed, the pressure that acts on anti-return card 3 places disappeared, anti-return card 3 openings merge, tube for transfusion 2 pathway closures, because anti-return card 3 is inverted cone, the blood of backflow can't flow out by card; This utility model has improved safety in utilization, effectively prevents and has avoided the blood backflow phenomenon in the infusion process, has reduced the difficulty of nursery work.
Claims (1)
