Problems solved by technology

[0002] At present, patients often use indwelling needles, infusion connectors, central venous catheters, peripheral central venous catheters, etc. during the infusion process. However, due to the limitations of their structure and materials, the hardness of the existing infusion connection tubes is not ideal. , the connecting tubes are relatively soft, and they are easy to be squeezed when not infused, causing blood return, causing tube blockage, and then causing thrombus formation. management, which increases the cost of medical treatment for patients and increases the workload of medical staff

Embodiment 1

[0019] Such as figure 1 As shown, the soft pressure-resistant tube is a soft pressure-resistant tube made of soft transparent polymer, the inner diameter of the tube is ≥0.7mm, the outer diameter of the tube is ≤3.0mm, the length of the tube is 1.0-20cm, and the outer surface of the tube is 1cm long Pressure resistance ≥ 0.75kg, one end of the soft pressure-resistant tube is connected to the first interface 1, and the other end of the soft pressure-resistant tube is connected to the second interface 2. The first interface 1 can be a male Luer connector or an indwelling needle hub, and the second interface 2 can be a positive pressure connector or a pressureless connector or a negative pressure connector or a heparin cap or a female Luer connector (such as Figure 7 shown).

Embodiment 2

[0021] Such as figure 2 As shown, the first interface 1 adopts a male Luer connector (such as Figure 8 As shown), the second interface 2 adopts a double-joint structure. All the other are with embodiment 1.

Embodiment 3

[0023] Such as image 3 As shown, the first interface 1 adopts an indwelling needle hub, and the second interface 2 adopts a positive pressure joint. All the other are with embodiment 1.

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 [0001] The invention relates to a soft pressure-resistant tube infusion set, which belongs to the technical field of medical infusion sets. Background technique [0002] At present, patients often use indwelling needles, infusion connectors, central venous catheters, peripheral central venous catheters, etc. during the infusion process. However, due to the limitations of their structure and materials used, the hardness of the existing infusion connection tubes is not ideal. , the connecting tubes are relatively soft, and they are easy to be squeezed when not infused, causing blood return, causing tube blockage, and then causing thrombus formation. Tube, increased the cost of medical treatment for patients, but also increased the workload of medical staff. Contents of the invention [0003] The present invention aims at the above-mentioned problems existing in the prior art and provides a soft pressure-resistant tube infusion set in which the catheter is le...
