Abstract

The utility model provides a disposable medical PICC catheter double-pipe flushing device. The medical PICC catheter flushing device is provided with two side-by-side, equal-length flushing pipes at the end of a flushing device. The outer end of the screw joint is provided with a screw joint, and each of the two screw joints is equipped with a screw protection cap. When in use, connect the two connectors of the PICC catheter double-tube flushing device with the two exposed infusion connectors of the patient's PICC catheter respectively, and flush the catheter with a positive pressure pulse method, which can keep the pipeline of the double-lumen PICC catheter unobstructed, and then The normal use of the catheter is ensured, the operation of the nurse is convenient, and the medical expenses are reduced.

Description

Disposable medical PICC catheter double tube flushing device

technical field

The utility model relates to a medical device, in particular to a disposable medical PICC catheter double-tube flushing device.

Background technique

The PICC catheter is a central venous catheter inserted through a peripheral vein. It can be left in the body for one year to avoid repeated venipuncture and cause pain to patients. It is suitable for patients with medium and long-term infusions. Regular maintenance is required during patient porting, and the catheter is kept patency by flushing the catheter with a pre-flushed catheter irrigator containing irrigation fluid before and after use. At present, because the traditional PICC catheter is a single-lumen catheter, it is not resistant to high pressure and cannot monitor central venous pressure, so it is gradually being eliminated clinically. The new double-lumen high-pressure resistant injection catheter (PowerPICC) is made of reinforced polyurethane material, which can be injected under high pressure. The double-lumen can also meet the complex long-term intravenous treatment needs of patients with acute trauma, shock, craniocerebral injury, and tumor patients. The application is more extensive. However, in the process of use, we found that if only one lumen of the double-lumen catheter is flushed, the tube wall on the other side will be squeezed and the volume will become smaller due to the expansion of the tube wall due to the increase in capacity in a short period of time. Negative pressure is easily formed in the squeezed lumen, and then the blood returns to form a thrombus, causing the tube to be blocked and affecting the normal use of the catheter. Therefore, in order to avoid this phenomenon, it is necessary to apply the same pressure to the two lumens at the same time to flush the catheter. If two pre-flushed catheter flushers are respectively connected to the two ports of the PICC catheter to flush the catheter at the same time, the operation is extremely inconvenient. It is convenient, but it may also cause blood return in the lumen on the side with low pressure due to uneven force application, and there is also a risk of catheter blockage, which poses a safety hazard.

Contents of the invention

The purpose of the utility model is to solve the above-mentioned existing problems and provide a disposable medical PICC catheter double-pipe flushing device, which can flush the two lumens of the PICC catheter at the same time and at equal pressure through one flushing device.

The utility model includes a flushing device, and the adopted technical scheme is that a medical PICC catheter flushing device is provided with two parallel and equal-length flushing pipes at the end of a flushing device with flushing liquid inside, and outside the two flushing pipes The ends are provided with screw joints.

The above-mentioned technical solution includes: two screw joints are respectively equipped with a screw protection cap.

The beneficial effect of the utility model is that: through the above-mentioned technical scheme, since the two joints of the flushing tube of the flushing device can be directly connected with the two exposed infusion joints of the double-cavity PICC catheter, the nurse can directly perform the operation of flushing the catheter, which solves the problem of At present, only one flusher is used to flush the tube or two flushers are used to flush the tube at the same time, causing uneven pressure in the two lumens of the catheter, which leads to the problem of catheter blockage. It is simple and practical in design, convenient for nurses to operate, and saves the cost of patients.
