Medical perfusion type irrigator

Abstract

The invention discloses a medical perfusion type irrigator, belonging to the technical field of medical equipment. The medical perfusion type irrigator comprises a microprocessor module and a peristaltic pump, wherein the microprocessor module sends signals to the peristaltic pump to control the liquid outlet pressure and liquid outlet flow speed of the peristaltic pump; the microprocessor module is connected with a keyboard module, a pressure sensor, a flow speed sensor and a display module. The medical perfusion type irrigator disclosed by the invention can provide irrigation fluids with two flow speeds and four pressures, and can accurately control the temperature of the irrigation fluids and realize continuous irrigation as well as intermittent irrigation; with human-machine interaction, the irrigator is friendly and convenient to operate; moreover, in a special situation, the irrigator can give an alarm through sound and light to remind the medical personnel to handle exception in time. The medical perfusion type irrigator disclosed by the invention is applicable to multiple operations and the irrigation of multiple operative sites or tissues.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical perfusion flusher with adjustable outlet pressure and flow rate. Background technique [0002] During the implementation of clinical surgery, there will be some pollutants such as smoke, excised tissue, bleeding, exudate, etc., attachments, and local high temperature, so it is necessary to treat the surgical site with a solution during the operation. Real-time cleaning, so medical perfusion pumps are used in clinical surgery. This kind of medical perfusion pump has high requirements on the temperature, pressure and flow rate of perfusate. Currently widely used medical perfusion pumps, on the one hand, mostly do not have a heating device, and only perfuse the pre-heated liquid when needed, which will make it difficult to control the temperature of the perfusate entering the patient's body. When it is lower than the safe value range, a large amount of perfusion...

Problems solved by technology

Secondly, there is no pressure and flow rate control device, and it is impossible to accurately control the flow rate and pressure of the irrigation fluid, which makes the control of the irrigation operation during the operation quite time-consuming and laborious, which seriously affects the progress of the operation.

These two technical solutions may be able to control the temperature of the perfusate, but the structure is relatively complicated, and the temperature change speed and overshoot control are not involved.

[0004] In order to solve the problem of flow rate and pressure control, for example, the Chinese utility model patent with application number 02249349.2 and titled "medical flushing equipment" discloses a flusher that presses out the liquid storage through the gas chamber, which can automatically supply liquid and flush with constant pressure. However, the flushing liquid is provided by the liquid storage tank, so it is only suitable for minimally invasive surgery in urology, bladder flushing, and other operations that require a small amount of liquid. It cannot be applied to operations that require continuous flushing and a large amount of liquid. The new model also cannot realize precise control of pressure and flow rate; for example, the Chinese utility model patent of 200420009239.7, named "Medical Irrigator", also discloses a medical flushing device, which controls the flow rate and pressure. Equipped with a water nozzle to control the shape of the flowing water, this device can only perform simple surgical irrigation, and is no longer suitable for operations that require high precision
