Portable continuous positive-pressure indwelling needle seal tube device

Abstract

The present invention provides a portable continuous positive pressure indwelling needle tube sealing device, which includes: a push device, a push plate is provided to compress the spring to store elastic force, a positive pressure cylinder device is provided with a piston, and the piston is tightly sleeved On the pushing platen, the spring is stretched to release the elastic pushing piston to compress the liquid as a positive pressure sealing tube, which can also be used as infusion or blood transfusion. The sleeve is worn on the wrist to carry the positive pressure indwelling needle sealing device at hand, so that the patient can walk around at will, which is convenient and safe.

Description

technical field [0001] The invention relates to a portable continuous positive pressure indwelling needle tube sealing device, especially a device that can seal the indwelling needle for a long time, and can be carried by the patient on the wrist to prevent thrombus A structure that endangers the safety of patients and can also be used for infusion or blood transfusion. Background technique [0002] Press, the existing indwelling needle needs to be used for more than one day after injection and infusion, but the syringe should be prefilled every eight hours, and physiological saline should be injected into the infusion port of the indwelling needle to prevent blood clots from endangering the safety of the patient. During the infusion with indwelling needles, the catheter must be sealed every eight hours, that is, the catheter should be sealed two to three times a day, and two to three pre-filled syringes with sealed catheters should be used. However, due to the insufficient ...

Problems solved by technology

[0002] Press, the existing indwelling needle needs to be used for more than one day after injection and infusion, but the syringe should be prefilled every eight hours, and physiological saline should be injected into the infusion port of the indwelling needle to prevent blood clots from endangering the safety of the patient. During the infusion with indwelling needles, the catheter must be sealed every eight hours, that is, the catheter should be sealed two to three times a day, and two to three pre-filled syringes with sealed catheters should be used. However, due to the insufficient number of medical staff in current medical institutions , there is often an excessive workload for a medical staff to take care of patients with more than 20 beds. The medical staff needs to frequently confirm whether the tube has been sealed, which increases the manpower burden of the medical staff and increases the burden on the patient. cost, needs to be improved

[0003] Furthermore, currently, the drips used by general patients all use the principle of gravity for injection. Therefore, in use, the injection must be lifted by using the drip stand. Although this drip type has a long history, and the most common users, However, there are indeed some troublesome problems in its actual use process. The drip stand mentioned above is not easy to carry due to its high height and bulk, which causes the patient's movement to be severely restricted. , taking items, etc., all cause inconvenience. What's more, when accidents (such as earthquakes, fires, floods, etc.) occur in the medical environment where the patient is located, the drip stand obviously becomes the biggest burden for the patient to escape from the scene, and it needs to be improved.

[0004] In view of the structure of the existing indwelling needle sealing tube and drip rack, the shortcomings in use and the unsatisfactory fact in its structural design, the inventor started to develop its solution, and the inventor hoped to develop a long-lasting Time infusion sealing tube is convenient to carry and has a safe positive pressure indwelling needle sealing tube structure to serve the public and promote the development of this industry. After a long time of conception, this invention was developed.
