Intensive care sampling device

Abstract

The invention relates to an intensive care sampling device characterized by comprising a switcher, an arterial catheter, a central venous catheter, a positive pressure joint and a medical pressure sensor, wherein the arterial catheter, the central venous catheter, the positive pressure joint and the medical pressure sensor are connected with the switcher. The switcher is provided with a first joint, a second joint, a third joint, a fourth joint and a fifth joint. The first joint is in communication with the arterial catheter through a first infusion tube, a normal pressure joint is mounted onthe second joint, the third joint is in communication with the central venous catheter through a second infusion tube, and the fifth joint is connected with an exhaust pipe. Hemostixes are mounted onthe first infusion tube and the second infusion tube. The intensive care sampling device has the advantages that a multifunctional monitoring sampling device is formed by mutual cooperation of the multi-channel switcher, the arterial catheter, the central venous catheter, a monitoring instrument and the positive pressure joint; the switching monitoring of arterial blood pressure and central venousblood pressure can be performed, and more importantly, the operational problems caused by multi-stage valves can be avoided.

Description

technical field [0001] The invention relates to an intensive care sampling device, in particular to an intensive care sampling device with low pollution probability and capable of realizing multi-catheter monitoring. Background technique [0002] Intensive care refers to intensive intensive treatment and nursing care for all kinds of critically ill patients admitted using various advanced medical technologies, modern monitoring and rescue equipment. To maximize the patient's survival and subsequent quality of life. The requirements for indoor architecture and facilities in the intensive care unit are higher than those in the general ward, so as to facilitate timely monitoring and rescue of critically ill patients to the greatest extent. In addition to the essential equipment in general wards, medical equipment is often equipped with a variety of monitoring equipment to monitor the vital indicators of patients in real time. [0003] Commonly used blood pressure monitoring i...

Problems solved by technology

[0005] At present, conventional blood collection devices use multiple three-way or four-way valves in series to perform necessary operations such as blood drawing and exhaust. Although it has the advantages of not easy to leak blood and is safe and reliable, it can only meet the requirements of a single catheter. The blood collection requirements are limited, and the use is limited; and the number of valves is large, usually more than two, the use is more complicated, and the technical requirements for puncture medical personnel are very high; and some three-way valves also need to use sealing caps. When the sealing cap is operated accordingly, it is easy to have the problem of the sealing cap falling and polluting, which is troublesome
