Description
The invention relates to the field of medical instruments, in particular to an automatic liquid drainage device.
In clinical care, a drainage device for storing drainage liquid of a patient usually needs nursing staff to frequently check and record the storage amount of the drainage liquid and timely pour the drainage liquid so as to prevent the drainage liquid from overflowing or reversely flowing back to a human body after being fully stored and causing iatrogenic pollution.
The electric suction device is clinically useful, but is often only applied to the operation or treatment process, and is used as a reusable medical device, which has higher price, is heavy and is not suitable for being carried by a patient.
The drainage catheter (such as a catheter and the like) applied to a patient is a disposable article, but can be used for a long time. The general drainage bag is disposable, short-term in use and wide in application, but a long section of drainage pipeline needs to be configured, so that a large amount of materials are wasted.
The volume of fluid is basically used as a record basis for treating the drained fluid clinically. The mechanical automatic urethral catheterization bag has the condition of low precision. The automatic catheterization system applying an electronic mode mostly uses hydraulic pressure and weight as detection bases, but when the proportion of urine of a patient is different, the converted volume has certain errors, and the products mainly solve the problems of intra-bladder pressure monitoring and bladder function exercise of the patient, cannot solve the problems of heavy, dirty and easily infected urine excrement dumping work in catheterization nursing, and cannot reduce the working pressure of nursing personnel and the infection risk.
Meanwhile, the electronic automatic catheterization system needs to place part of electronic elements in the drainage catheter, if the outer insulating layer is damaged, the situation that drainage liquid is electrified easily occurs, and the safety of a patient is endangered.
When the electronic drainage valve of the existing electronic urethral catheterization product is powered off or has other faults, a spare solution is not available, and drainage liquid is easy to flow reversely, so that medical accidents are caused.
During the nursing period of patients with serious infectious diseases such as ebola and plague, the open collection of drainage liquid is easy to cause disease transmission. When the urine excrement of a patient is treated by hands and used products are treated, the requirement of perfect sealing post-treatment cannot be met due to the fact that matched perfect sealing equipment is not available, the urine excrement is required to be transferred into an independent sealing container for destruction, the risk of infection of nursing staff is increased while materials are wasted, and therefore a high-safety product which reduces material waste, can collect drainage liquid in a sealed mode and can avoid direct contact is needed.
