Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an intelligent pneumoperitoneum machine with air pressure stabilization and heating functions. Background Technology

[0002] An insufflator is a specialized device for establishing and maintaining pneumoperitoneum during laparoscopic surgery. It is classified into pneumatic insufflators and electronic insufflators according to their driving method.

[0003] To alleviate patient discomfort, existing insufflators heat the gas to increase its temperature when it enters the abdomen. However, existing insufflators typically heat the gas directly, which can easily lead to excessively high gas temperatures and is not conducive to maintaining the gas pressure stability inside the insufflator. Therefore, there is an urgent need for an intelligent insufflator with both pressure stabilization and heating functions. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problem that direct heating of gas by the existing insufflator can easily lead to excessively high gas temperature and unstable gas pressure. Thus, an intelligent insufflator with gas pressure stabilization and heating functions is provided.

[0005] To solve the above-mentioned technical problems, this utility model provides an intelligent pneumoperitoneum machine with air pressure stabilization and heating functions, comprising:

[0006] A housing, wherein the housing contains:

[0007] A buffer chamber, wherein the buffer chamber is equipped with:

[0008] A first air inlet and a first air outlet, wherein a following is provided between the first air inlet and the first air outlet:

[0009] Gas channel, the gas channel comprising, in sequence, the following:

[0010] The buffer chamber includes a first channel, a second channel, a third channel, and a fourth channel, and the bottom of the buffer chamber is also equipped with:

[0011] Heating pad.

[0012] As a further improvement of this utility model, the gas channel is provided in multiple ways, and the multiple gas channels are connected in sequence to connect the first air inlet and the first air outlet.

[0013] As a further improvement of this utility model, the first channel extends upward, the second channel extends laterally, the third channel extends downward, and the fourth channel extends laterally.

[0014] As a further improvement of this utility model, the housing is provided with a second air inlet and a second air outlet, the first air inlet and the second air inlet are connected, and the first air outlet and the second air outlet are connected.

[0015] As a further improvement of this utility model, the second air inlet is provided with an air inlet interface.

[0016] As a further improvement of this utility model, the second air outlet is provided with an air outlet interface.

[0017] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0018] This invention relates to an intelligent pneumoperitoneum machine with pressure stabilization and heating functions. The gas in the buffer chamber is heated by a heating pad placed at the bottom of the buffer chamber. The gas passage slows down the gas's forward speed, which helps stabilize the gas pressure. Furthermore, the heat conduction at the bottom of the buffer chamber prevents the gas from being directly heated, thus avoiding excessive temperature rise. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] It should be noted that when a component is referred to as being "set on" or "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is referred to as being "fixed to" another component, or "fixedly connected" to another component, the fixing method can be detachable or non-detachable. When a component is considered to be "connected" or "rotatably connected" to another component, it can be directly connected to the other component or there may be an intermediate component. The terms "vertical," "horizontal," "left," "right," "upper," "lower," and similar expressions used are for illustrative purposes only and do not represent the only possible implementation.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] In this utility model, terms such as "first," "second," and "third" are used not to represent specific quantities or orders, but merely to distinguish names.

[0029] In some embodiments, refer to Figures 1-4 As shown, this utility model discloses an intelligent pneumoperitoneum machine with air pressure stabilization and heating functions, comprising:

[0030] Housing 1, wherein housing 1 contains:

[0031] Buffer chamber 2, wherein the buffer chamber 2 is provided with:

[0032] A first air inlet 3 and a first air outlet 4 are provided, and the first air inlet 3 and the first air outlet 4 are provided with the following:

[0033] Gas channel, the gas channel comprising, in sequence, the following:

[0034] The first channel 5, the second channel 6, the third channel 7, and the fourth channel 8, and the bottom of the buffer chamber 2 is also provided with:

[0035] Heating pad 9.

[0036] When the gas enters the buffer chamber 2 through the first air inlet 3, it is heated by the heating pad 9 at the bottom of the buffer chamber 2 as it passes through the first channel 5, the second channel 6, the third channel 7 and the fourth channel 8. This makes the gas more fully heated and the gas pressure more stable. At the same time, since the heating pad 9 indirectly transfers heat to the gas through the bottom of the buffer chamber 2, the gas is prevented from being overheated.

[0037] In one embodiment, the gas channels are provided in multiple ways, and the multiple gas channels are connected in sequence to connect the first air inlet 3 and the first air outlet 4.

[0038] By setting up multiple gas channels, the residence time of the gas in the buffer chamber 2 can be further extended, thus ensuring that the gas is fully heated.

[0039] In one embodiment, the first channel 5 extends upward, the second channel 6 extends laterally, the third channel 7 extends downward, and the fourth channel 8 extends laterally.

[0040] When the gas enters the buffer chamber 2 and is heated, it extends upward along the first channel 5 and enters the third channel 7 along the second channel 6. The third channel 7 extends downward. At this time, the gas has been heated and the hot gas flows upward, thereby prolonging the residence time of the gas in the third channel 7, ensuring stable gas pressure and gas temperature, and finally flowing out through the fourth channel 8.

[0041] In one embodiment, the housing 1 is provided with a second air inlet and a second air outlet, the first air inlet 3 is connected to the second air inlet, and the first air outlet 4 is connected to the second air outlet.

[0042] The second air inlet and the second air outlet make it easier for gas to enter and exit the buffer chamber 2.

[0043] In one embodiment, the second air inlet is provided with an air inlet interface 10.

[0044] By setting the air intake interface 10, it is easy to connect an external gas source.

[0045] In one embodiment, the second air outlet is provided with an air outlet interface 11.

[0046] By setting the gas outlet 11, it is easy to introduce gas into the patient's body.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
