Description

Technical Field

[0001] The utility model relates to a medical surgical flushing machine. Background Art

[0002] In surgical operations, it is often necessary to use a flushing device to flush the patient's wound to prevent infection at the surgical site or affect the progress of the operation. However, the existing flushing device cannot promptly remove the waste liquid accumulated at the surgical site after flushing, which hinders the progress of the operation. In addition, the flushing liquid will be heated to 36°C-37°C before flushing by medical staff. However, since the operating environment temperature is around 22°C, there is a temperature difference with the flushing liquid. If the operation time is prolonged, the temperature of the flushing liquid will also drop to the point of being unusable. Medical staff have to reheat the flushing liquid or replace it with the heated flushing liquid. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a medical surgical flushing machine, which is used to solve the problems that the existing surgical flushing device does not have the integrated flushing and suction function and the flushing liquid cannot maintain a constant temperature.

[0004] In order to solve the above problems, the technical solution of the utility model is:

[0005] The medical surgical flushing machine comprises a flushing machine body, on which is provided a constant temperature chamber for accommodating and heating a flushing liquid bag, a peristaltic pump for extracting flushing liquid from the flushing liquid bag, and a negative pressure suction device for extracting flushing waste liquid.

[0006] The negative pressure suction device comprises an air suction pump installed in the main body, and the air suction pump is connected to the negative pressure bottle through an air suction pipe.

[0007] The constant temperature chamber includes a heating tank arranged in a main body and a tank cover covering the heating tank. An electric heating plate is arranged in the heating tank, and a first temperature sensor is installed on the electric heating plate. The first temperature sensor and a pressure sensor installed on the exhaust pipe are connected to a controller input end, and the electric heating plate, a peristaltic pump and an exhaust pump are connected to a control output end. An operation panel connected to the controller is also arranged on the main body.

[0008] The utility model also comprises a foot switch which is connected to the input terminal of the controller.

[0009] The slot cover is hinged to the body through a plurality of bent rods, a micro switch is installed in the body below the bent rod, the micro switch is triggered by the bent rod, and the micro switch is connected to the input end of the controller.

[0010] Both the heating tank and the tank cover are provided with a heat-insulating layer.

[0011] A plurality of universal wheels are arranged under the main body.

[0012] The beneficial effects of the utility model are as follows: the surgical flushing machine can not only flush the patient's wound, but also absorb the flushing waste liquid after flushing the wound to prevent the waste liquid from accumulating on the operating table, and at the same time can keep the flushing liquid warm so that its temperature can be automatically maintained between 36°C and 37°C for a long time. The structure is simple and the use is safe and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] like Figure 1 As shown, the medical surgical flushing machine includes a flushing machine body 1, on which is provided a constant temperature chamber 2 for accommodating and heating a flushing liquid bag, a peristaltic pump 4 for extracting the flushing liquid in the flushing liquid bag, and a negative pressure suction device for extracting the flushing waste liquid in and out.

[0021] The negative pressure suction device comprises an air pump 9 installed in the main body 1 , and the air pump 9 is connected to the negative pressure bottle 5 through an air suction pipe.

[0022] The constant temperature chamber 2 includes a heating tank 21 arranged in the main body 1 and a tank cover 22 covering the heating tank 21. An electric heating plate 24 is arranged in the heating tank 21. A first temperature sensor 25 is installed on the electric heating plate 24. The first temperature sensor 25 is connected to the controller input end, and the electric heating plate 24, the peristaltic pump 4 and the vacuum pump 9 are connected to the control output end. An operation panel 3 connected to the controller is also arranged on the main body 1.

[0023] The operation panel 3 is provided with a main switch, a temperature adjustment button, a peristaltic pump adjustment button, a temperature digital display screen, a pressure digital display screen and a vacuum pump switch button.

[0024] A hole is provided on the electric heating plate, and a second temperature sensor 26 is installed on the hole. The first temperature sensor 25 is a PT100 temperature sensor, and the first temperature sensor 25 is used to detect the temperature of the electric heating plate 24, and the second temperature sensor is an infrared temperature sensor, and is used to detect the temperature of the flushing liquid bag.

[0025] When the utility model is used, the medical staff puts the flushing liquid bag into the heating tank 21 and covers the tank cover 22, and then the electric heating plate 24 heats the flushing liquid. When the first temperature sensor 25 detects that the temperature reaches 60°C, the controller controls the electric heating plate 24 to disconnect. When the temperature drops to 50°C, the electric heating plate 24 is controlled to start, thereby quickly heating the flushing liquid bag. With the continuous heating of the electric heating plate 24, the temperature of the saline in the flushing liquid bag also increases. When the second temperature sensor detects that the saline temperature reaches 37°C, the electric heating plate 24 is controlled to stop. When the saline temperature drops to 36°C, the electric heating plate 24 is controlled to start, so as to maintain the flushing liquid temperature between 36°C and 37°C. When it is necessary to flush the patient's wound, the flushing tube is assembled to the peristaltic pump 4, then one end of the flushing tube is docked with the flushing liquid bag, and then the suction tube is docked with the negative pressure bottle 5. Finally, after starting the peristaltic pump 4 and the suction pump 9, the flushing tube and the suction tube can be used to flush the patient's wound.

[0026] The device also includes a foot switch connected to the controller input terminal. When the flushing needs to be paused, the doctor can use the foot switch to pause the peristaltic pump 4 and the suction pump 9, so that the doctor does not need to operate with his hands, thereby avoiding the situation where the doctor touches the flushing machine first and then touches the patient's wound, causing wound contamination.

[0027] The tank cover 22 is hinged to the body 1 through a plurality of curved rods 7, and a micro switch 8 is installed in the body 1 below the curved rod 7. The micro switch 8 is triggered by the curved rod, and the micro switch 8 is connected to the controller input terminal. When the tank cover 22 is opened, the controller controls the electric heater and the peristaltic pump 4 to stop, so as to facilitate the replacement of a new flushing liquid bag. In addition, after the tank cover 22 is opened, the electric heating plate 24 stops heating to prevent burns and dry burning.

[0028] A heat preservation layer 23 is provided on the heating tank 21 and the tank cover 22. The heat preservation layer 23 is an aluminum foil heat preservation pad to prevent heat loss and improve the heating speed.

[0029] A plurality of universal wheels 6 are installed under the main body 1 to facilitate the movement of the washing machine.

[0030] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
