CN201930327U - Reverse-flow type disposable infusion tube - Google Patents

Abstract

The utility model discloses a reverse-flow type disposable infusion tube and particularly relates an intravenous infusion tube capable of being used for pressurization, belonging to intravenous infusion equipment. The reverse-flow type disposable infusion tube consists of a medicine bag hose, a Murphy's tube, a syringe needle hose and a syringe needle that are connected with one another in sequence; and the reverse-flow type disposable infusion tube is characterized in that a hard elbow is connected at the lower end of the medicine bag hose. The reverse-flow type disposable infusion tube has the benefits that as the hard elbow is arranged at he lower end of the medicine bag hose and provided with a suspension ring, when the reverse-flow type disposable infusion tube is in use, the Murphy's tube can be kept in a vertical state by hanging the suspension ring at a certain height so as to be convenient to observe the infusion state and control infusion speed, the medicine bag with a pressurization device can be put at any height and any position and the hose can not be folded and cause the phenomenon of liquid medicine blockage. The reverse-flow type disposable infusion tube has a good effect on ensuring the infusion safety.

Description

Reverse-flow one-time infusion tube

Technical field

This utility model belongs to venous transfusion equipment, particularly can be used for the venous transfusion pipe that pressurizes.

Background technology

Venous transfusion medicated bag that the use non-toxic plastic is made and the one-time infusion tube that is mated use, little in light weight with its volume, advantages such as safe ready, obtain large-area applying, but this combination can only be suspended to eminence with medicated bag, rely on gravity and atmospheric pressure, make the drug slow in the bag splash into human body uniformly.At can not highly hanging the situation of carrying out because external condition is limit, people have developed pressue device, though pressue device has solved high extension problem, but the Murphy's pipe needs vertical the use in transfusion, the medicated bag flexible pipe just needs folding bending like this, and the folding bending of flexible pipe causes medicinal liquid to flow smooth easily or blocks.

The utility model content

Cause the medicinal liquid deficiency smooth or that block that flows when folding crooked easily in order to overcome existing one-time infusion tube flexible pipe, this utility model provides a kind of reverse-flow one-time infusion tube, and this reverse-flow one-time infusion tube can prevent that when bending medicinal liquid from blocking.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of reverse-flow one-time infusion tube, comprise the medicated bag flexible pipe, Murphy tube, syringe needle flexible pipe, the syringe needle that link to each other successively, it is characterized in that: described medicated bag flexible pipe lower end is connecting the hard elbow.

Described hard elbow and Murphy's pipe are connected as a single entity.

Described hard elbow links to each other with the Murphy's pipe by connecting flexible pipe.

On the described hard elbow suspension ring are housed.

The beneficial effects of the utility model are owing to being provided with the hard elbow in the lower end of medicated bag flexible pipe and suspension ring being installed on elbow, suspension ring can be suspended to the plumbness that a certain height keeps the Murphy's pipe during use, be convenient to observe transfusion state, control transfusion speed, use the medicated bag of pressue device can be put into arbitrary height and position, the folding phenomenon that causes medicinal liquid to block of flexible pipe also can not occur, this utility model is for guaranteeing that transfusion safety has good effect.

Fig. 2 is the structural representation of another embodiment.

Among the figure, 1. syringe needle flexible pipe, 2. Murphy's pipe, 3. medicated bag flexible pipe, 4. hard elbow, 5. suspension ring 6. connect flexible pipe.

The specific embodiment

The specific embodiment of the present utility model is, as shown in the figure:

Embodiment 1, a kind of as shown in Figure 1 reverse-flow one-time infusion tube, comprise the medicated bag flexible pipe 3, Murphy tube 2, syringe needle flexible pipe 1, the syringe needle that link to each other successively, it is characterized in that: described medicated bag flexible pipe lower end is connecting hard elbow 4, hard elbow and Murphy's pipe are connected as a single entity, and suspension ring 5 are housed on the hard elbow.

Embodiment 2, a kind of as shown in Figure 2 reverse-flow one-time infusion tube, comprise the medicated bag flexible pipe 3, Murphy tube 2, syringe needle flexible pipe 1, the syringe needle that link to each other successively, it is characterized in that: described medicated bag flexible pipe lower end is connecting hard elbow 4, and the hard elbow links to each other with the Murphy's pipe by connecting flexible pipe 6.

Above embodiment only be part embodiment of the present utility model so long as hard material be used for disposable transfusion device play change flow direction, support, be convenient to the contrary action of gravity input human body of adding pressure type infusion vessel herb liquid or/and work effects such as fixing all belong to the patentee's interest field.

Claims (4)

1. a reverse-flow one-time infusion tube comprises the medicated bag flexible pipe, Murphy tube, syringe needle flexible pipe, the syringe needle that link to each other successively, and it is characterized in that: described medicated bag flexible pipe lower end is connecting the hard elbow.
