Abstract
The utility model relates to a transfusion device with a flexible pressure-resisting tube. The flexible pressure-resisting tube is made of flexible transparent polymers and has internal diameter longer than or equal to 0.7mm, external diameter shorter than or equal to 3.0mm and the tube length of 1.0-20cm; the outer side surface of the tube has pressure-resisting force larger than or equal to 0.75kg per centimeter; one end of the flexible pressure-resisting tube is connected with a first interface (male Luer connector or remaining needle seat), and the other end of the flexible pressure-resisting tube is connected with a second interface (positive pressure connector or non-pressure connector or negative pressure connector or heparin cap or female Luer connector); the flexible pressure-resisting tube is also provided with a close stop clamp; a clamping plate of the close stop clamp has the thickness of 1.0mm-2.5mm; the bending position of the lower end of the close stop clamp forms a supporting table, and the length of the supporting table is longer than the external diameter of the flexible pressure-resisting tube; and the clamping plate of the close stop clamp is provided with a circular hole and a slot. The utility model prevents extrusion blood return after transfusion, thereby needing no heparinate water seal tube; and in addition, the utility model reduces the treatment cost of patients and the work load of medical workers.
Description
Technical field
This utility model relates to a kind of soft pressure tube infusing apparatus, belongs to medical transfusion utensil technical field.
Background technology
At present, the patient often uses remaining needle, infusion connector, central venous catheter, periphery central venous catheter etc. in infusion process, and existing these transfusion connection tubes, because the restriction of its structure and material therefor, the hardness of connection tube is not ideal enough, connection tube is all softer, be easy to when not infusing be expressed to, cause the blood back phenomenon, cause the generation of plugging, and then cause the formation of thrombosis, for reducing the formation of thrombosis, all to use the heparin saline tube sealing after the each transfusion of medical personnel, increase patient's the cost of curing the disease, increase medical personnel's workload again.
The utility model content
The problem that this utility model exists at above-mentioned prior art and be retained in the not soft pressure tube infusing apparatus of blood back of body inner catheter after a kind of transfusion is provided.
The technical solution of the utility model is as follows:
A kind of soft pressure tube infusing apparatus, comprise first interface, soft pressure pipe, second interface, only close folder, it is characterized in that: the soft pressure pipe of making by the soft transparent polymer, bore 〉=0.7mm, external diameter of pipe≤3.0mm, pipe range is 1.0-20cm, long compression resistance 〉=the 0.75kg of the every 1cm of pipe lateral surface, one end of soft pressure pipe is connected with first interface, the other end of soft pressure pipe is connected with second interface, first interface is public female Luer or keeps somewhere needle stand that second interface is positive pressure connector or does not have crimp head or negative pressure joint or calparine cap or female female Luer.
Also be provided with on the described soft pressure pipe and only close folder, the thickness that only closes the folder clamping plate is 1.0mm-2.5mm, the bending part that only closes the folder lower end forms brace table, the length of brace table is greater than the external diameter of soft pressure pipe, only close that folder offers circular hole on the clamping plate and folder meets, the diameter of its circular hole is greater than soft pressure pipe external diameter, and the width that its folder meets is less than the value of 2 times of soft pressure pipe wall thickness.
The beneficial effects of the utility model are:
This utility model soft pressure tube infusing apparatus has solved the blood back, the plugging that easily produce for a long time, has caused thrombotic problem after transfusion, avoided the generation of extruding blood back, and then do not need to use the heparin saline tube sealing, patient's the cost of curing the disease is reduced, alleviated medical personnel's workload again.

The specific embodiment
Describe this utility model in detail below in conjunction with drawings and Examples.
As shown in Figure 1, the soft pressure pipe that soft pressure pipe is made by the soft transparent polymer, bore 〉=0.7mm, external diameter of pipe≤3.0mm, pipe range is 1.0-20cm, long compression resistance 〉=the 0.75kg of the every 1cm of pipe lateral surface, an end of soft pressure pipe is connected with first interface 1, and the other end of soft pressure pipe is connected with second interface 2.First interface 1 can be public female Luer or keep somewhere needle stand that second interface 2 can be positive pressure connector or not have crimp head or negative pressure joint or calparine cap or female female Luer (as shown in Figure 7).
As shown in Figure 2, first interface 1 adopts public female Luer (as shown in Figure 8), and second interface 2 adopts the dual terminal structure mode.All the other are with embodiment 1.
As shown in Figure 3, first interface 1 adopts keeps somewhere needle stand, and second interface 2 adopts positive pressure connector.All the other are with embodiment 1.
As shown in Figure 4, first interface 1 adopts keeps somewhere needle stand, and second interface 2 adopts the dual terminal structure mode.All the other are with embodiment 1.
As Fig. 5-shown in Figure 6, also be provided with on the soft pressure pipe and only close folder 4, the thickness that only closes folder 4 clamping plate is 1.0mm-2.5mm, the bending part that only closes folder 4 lower ends forms brace table, the length L of brace table is greater than the external diameter of soft pressure pipe 3, only close that folder offers circular hole on 4 clamping plate and folder meets, the diameter of its circular hole is greater than soft pressure pipe 3 external diameters, and the width that its folder meets is less than the value of 2 times of soft pressure pipe 3 wall thickness.
