Abstract
The invention relates to a soft pressure tube infusing apparatus. The internal diameter of a soft pressure tube which is made from soft transparent polymer is more than or equal to 0.7 mm, the external diameter is less than or equal to 3 mm, and the length is 1.0-2.0 cm. The outer side surface of the soft pressure tube can bear the pressure of 0.7 kg or more by every 1 cm length. One end of the soft pressure tube is connected with a first interface which can be a male Ruhr joint and an indwelling needle bed, and the other end is connected with a second interface which can be a positive-pressure joint, a non-pressure joint, a negative-pressure joint, a heparin cap and a female Ruhr joint. The soft pressure tube is provided with a stopping and closing clip which has the thickness of 1.0-2.5mm; a supporting platform whose length is larger than the external diameter of the soft pressure tube is formed at the bent part of the lower end of the stopping and closing clip; and the stopping andclosing clip is provided with a round hole and a slot. The invention avoids the blood return due to squeezing after the liquid medicine infusion, does not need a heparin saline sealing tube, lowers the disease treatment cost of the patient and alleviates the workload of the medical staff.
Description
Technical field
The present invention relates to a kind of soft pressure tube infusing apparatus, belong 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.
Summary of the invention
The present invention is directed to the problem of above-mentioned prior art existence 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.
Technical scheme of the present invention 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 invention has the beneficial effects as follows:
Soft pressure tube infusing apparatus of the present invention 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 the present invention 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.
