Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to an anesthesia machine. Background Art

[0002] The anesthesia machine is one of the most commonly used equipment in the operating room. In order to absorb the carbon dioxide in the patient's breathing gas, the anesthesia machine is often equipped with a carbon dioxide absorber. The carbon dioxide absorbent (usually soda lime particles or calcium lime particles) in the carbon dioxide absorber will gradually change color as the carbon dioxide is absorbed. The doctor will judge whether the carbon dioxide absorbent needs to be replaced based on the color change. The carbon dioxide absorber is usually located under the workbench and circuit of the anesthesia machine. In a brighter environment, the doctor can clearly see the color change of the carbon dioxide absorber. However, in a darker environment, the carbon dioxide absorber does not receive enough light, and it is difficult for the doctor to judge the color change of the carbon dioxide absorber, which may lead to untimely replacement of the carbon dioxide absorber and cause abnormal breathing gas in the patient. Summary of the invention

[0003] In view of this, an embodiment of the present invention provides an anesthesia machine, which is convenient for doctors to judge the color change of the carbon dioxide absorbent in various situations, thereby facilitating the timely replacement of the carbon dioxide absorbent.

[0005] The carbon dioxide absorption tank is installed on the anesthesia machine body;

[0006] The carbon dioxide absorption tank contains a carbon dioxide absorbent for absorbing carbon dioxide;

[0007] The lighting device is used to illuminate the carbon dioxide absorption tank.

[0008] When the anesthesia machine provided by the present invention is used in a dark environment, the lighting device is started to illuminate the carbon dioxide absorber, so that the doctor can judge the color change of the carbon dioxide absorber in various situations, thereby facilitating the timely replacement of the carbon dioxide absorber.

DETAILED DESCRIPTION

[0016] The following will be combined with the attached examples of the present application Figure 1-4 , the technical solutions in the embodiments of the present application are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0017] like Figure 1-4 As shown, the anesthesia machine provided by the embodiment of the present invention includes an anesthesia machine body 1, a carbon dioxide absorption tank 2 and a lighting device 3.

[0018] The carbon dioxide absorption tank 2 is made of a transparent material and is installed on the anesthesia machine body 1. Specifically, the carbon dioxide absorption tank 2 is detachably installed on the anesthesia machine body 1, which is convenient for replacing and disassembling the carbon dioxide absorption tank 2. In order to facilitate the taking of the carbon dioxide absorption tank 2, a tank handle 14 is also provided on the side wall of the carbon dioxide absorption tank 2. In order to prevent slipping when holding the tank handle 14, an anti-slip layer is provided on the tank handle 14. The anti-slip layer can be etched on the tank handle 14, or can be integrally molded with the tank handle 14 by injection molding, or can be an anti-slip sticker pasted on the tank handle 14.

[0019] The carbon dioxide absorption tank 2 contains a carbon dioxide absorbent for absorbing carbon dioxide.

[0020] The lighting device 3 is used to illuminate the carbon dioxide absorption tank 2. The lighting device 3 can be installed at any position, for example, on the anesthesia machine body 1, on the carbon dioxide absorption tank 2, or a bracket is provided next to the lighting device 3 and the lighting device 3 is installed on the bracket.

[0021] Furthermore, the present invention discloses a lighting device 3 including a light source capable of providing lighting.

[0022] In order to facilitate uniform light dispersion of the light source, the lighting device 3 disclosed in the present invention further includes a diffuser, and the diffuser covers the light source.

[0023] Specifically, the present invention discloses that at least part of the cross-section of the diffuser is elliptical, circular, rectangular or square. It should be noted that the diffuser may also be in other shapes.

[0024] Furthermore, the present invention discloses that the anesthesia machine further includes a control device, which controls the lighting device 3. Specifically, the control device may only control the on / off of the lighting device 3, or may not only control the on / off of the lighting device 3, but also control the brightness of the lighting device 3.

[0025] Specifically, the control device may be any device capable of controlling the lighting device 3. For example, the control device is a control circuit or a controller. It should be noted that the control device may be a controller (CPU) on an anesthesia machine, or a separately provided control chip or controller.

[0026] Furthermore, the present invention discloses that the anesthesia machine also includes a control information input device, and the control information input device is signal-connected with the control device. Specifically, the control information input device and the control device may be electrically connected or communication-connected.

[0027] Furthermore, the present invention discloses that the control information input device includes one or more of a light sensor, a humidity sensor, a sound sensor, a carbon dioxide gas detection sensor, a switch or an information input device, etc. Specifically, the control information input device may include only any one of the light sensor, the humidity sensor, the sound sensor, the carbon dioxide gas detection sensor, the information input device or the switch, etc., or may include two or more of the above at the same time, etc. The information input device may be a device that can input information, such as a keyboard and a touch screen.

[0028] When the control information input device only includes a light sensor, the control device is connected to the light sensor signal. The light sensor is placed on the anesthesia machine body 1. Specifically, the light sensor is located near the carbon dioxide absorption tank 2 and is located on the side of the carbon dioxide absorption tank 2 facing the operator when operating the anesthesia machine, so as to improve the accuracy of the lighting device 3 in timely lighting. It should be noted that the light sensor can also be placed on the carbon dioxide absorption tank 2, or the light sensor can be placed at other positions of the anesthesia machine body 1.

[0029] When the light brightness detected by the light sensor is lower than the preset brightness value, the light sensor transmits a signal to the control device, and the control device controls the light source of the lighting device 3 to be bright. The preset brightness refers to the brightness at which the currently detected brightness value is insufficient for the operator to identify whether the carbon dioxide absorbent in the carbon dioxide absorption tank 2 has changed color. It should be noted that the control device controls the brightness of the lighting device 3 according to the ambient brightness detected by the light sensor.

[0030] When the control information input device only includes a humidity sensor, the control device is connected to the humidity sensor signal. The humidity sensor is placed in the carbon dioxide absorption tank 2, specifically, it can be installed on the inner tank wall of the carbon dioxide absorption tank 2, or it can be installed on the tank cover 5 of the carbon dioxide absorption tank 2. When the humidity value detected by the humidity sensor is greater than the preset humidity value, the humidity sensor transmits a signal to the control device, and the control device controls the light source of the lighting device 3 to light up. It should be noted that the preset humidity value can be set as needed. When it exceeds this value, it means that the water generated by the carbon dioxide absorbent absorbing carbon dioxide cannot be absorbed and released into the carbon dioxide absorption tank 2, resulting in high humidity. At this time, it means that the carbon dioxide absorbent in the carbon dioxide absorption tank 2 needs to be replaced. The control device controls the lighting device 3 to illuminate the carbon dioxide absorption tank 2, which provides a warning effect on the one hand, and on the other hand, in an environment with insufficient light intensity, enables the operator to see the discoloration of the carbon dioxide absorbent in the carbon dioxide absorption tank 2 and confirm whether it needs to be replaced.

[0031] When the control information input device only includes a carbon dioxide gas detection sensor, the control device is connected to the carbon dioxide gas detection sensor signal. The carbon dioxide gas detection sensor is placed in the carbon dioxide absorption tank 2, specifically, it can be installed on the inner tank wall of the carbon dioxide absorption tank 2, or it can be installed on the tank cover 5 of the carbon dioxide absorption tank 2. When the carbon dioxide gas detection sensor detects that the carbon dioxide concentration value in the carbon dioxide absorption tank 2 exceeds the preset carbon dioxide concentration value, the control device controls the lighting device 3 to illuminate the carbon dioxide absorption tank 2. The preset carbon dioxide concentration value can be set as needed. When it exceeds this value, it means that the carbon dioxide absorbent has insufficient ability to absorb carbon dioxide, and the carbon dioxide absorbent in the carbon dioxide absorption tank 2 needs to be replaced. The control device controls the lighting device 3 to illuminate the carbon dioxide absorption tank 2, which provides a warning effect on the one hand, and on the other hand, in an environment with insufficient light intensity, enables the operator to see the color change of the carbon dioxide absorbent in the carbon dioxide absorption tank 2 and confirm whether it needs to be replaced.

[0032] When the control information input device only includes a switch, the switch can be installed on the anesthesia machine body 1 or on the carbon dioxide absorption tank 2 .

[0033] Furthermore, the present invention discloses that the switch is a knob switch, a voice-controlled switch, a touch switch, a lever, a physical button or a virtual button, etc.

[0034] When the switch is a knob switch, the lighting brightness and on / off adjustment can be achieved by rotating the knob switch.

[0035] Specifically, when the knob switch is a virtual button, the virtual button can be integrated on the display of the anesthesia machine body 1 .

[0037] When the lighting device 3 is installed on the anesthesia machine body 1, the present invention discloses that the lighting device 3 is recessed or protruded from the anesthesia machine body 1. That is, the lighting device 3 can be recessed in the anesthesia machine body 1, making the anesthesia machine look beautiful; the lighting device 3 can also be protruded from the anesthesia machine body 1, making it easier for the light of the lighting device 3 to irradiate the carbon dioxide absorption tank 2.

[0038] Furthermore, the present invention discloses that the lighting device 3 is embedded in the anesthesia machine body 1, which increases the connection strength between the lighting device 3 and the anesthetic body.

The lighting device 3 can also be embedded in the outer wall of the tank body 4 or the inner wall of the tank body 4.

[0049] It should be noted that, in order to facilitate the adjustment of the position of the lighting device 3 on the carbon dioxide absorption tank 2, the lighting device 3 can also be slidably installed on the outer wall of the tank body 4.
