Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and in particular relates to a pneumoperitoneum tube with temperature monitoring, and a pneumoperitoneum temperature monitoring device of a pneumoperitoneum machine. Background Art

[0002] Laparoscopic surgery involves inserting instruments into the abdominal cavity through a tiny incision in the abdomen. The pneumoperitoneum machine is an essential device for establishing and maintaining pneumoperitoneum in laparoscopic surgery. To establish pneumoperitoneum, CO2 gas needs to be filled into the patient's abdominal cavity. Since CO2 is stored at low temperatures, the gas temperature is usually much lower than human body temperature. Therefore, the injection of low-temperature CO2 gas can easily cause the endoscope to fog up, seriously affecting the doctor's visual experience and increasing surgical risks. In order to prevent the CO2 output temperature of the pneumoperitoneum machine from being too low, the gas source needs to be heated and pre-treated to keep the input CO2 temperature consistent with the temperature in the abdominal cavity as much as possible, thereby reducing the patient's surgical risk.

[0003] Existing insufflators usually heat the internal pipes of the main machine. Because the insufflator tube is often long, it will exchange heat with the external environment when transmitting heated CO2 gas, which causes a large temperature difference between the insufflator outlet heated by the internal pipe of the main machine and the insufflator tube port (insufflator end), which can be as high as 40 degrees or more.

[0004] Existing insufflators pay more attention to the airflow temperature at the outlet of the insufflator, while the actual insufflator end temperature is ignored. Some technicians have discovered the above problem and have conducted research to improve the insufflator end temperature. At present, although the insufflator end temperature has improved to a certain extent, it is still a certain distance from the actual human body temperature. We urgently need to improve the problem of large temperature difference between the outlet of the insufflator and the port of the insufflator tube (insufflator end). Utility Model Content

[0005] The main purpose of the utility model is to provide a pneumoperitoneum tube with temperature monitoring and a pneumoperitoneum temperature monitoring device for a pneumoperitoneum machine. The pneumoperitoneum tube and the monitoring device can reduce the temperature difference between the air outlet of the pneumoperitoneum machine and the port of the pneumoperitoneum tube, alleviate endoscope fogging, and reduce surgical risks.

[0018] The heat-insulating tube is in a hollow cylindrical shape and is sleeved outside the pneumoperitoneum tube body; a gap area is formed between the inner tube wall of the heat-insulating tube and the outer tube wall of the pneumoperitoneum tube body, and the gap area is a heat-insulating area (heat-insulating cavity); and the heat-insulating area is in a closed state and isolated from the external environment, that is, the heat-insulating area (heat-insulating cavity) is a closed cavity;

[0019] The temperature sensor is placed in the heat-insulating cavity and close to the pneumoperitoneum end tube port; the temperature sensor collects the surface temperature of the pneumoperitoneum tube body (the CO2 gas flow temperature inside the pneumoperitoneum tube body), and transmits the collected surface temperature of the pneumoperitoneum tube body to the temperature control system of the pneumoperitoneum machine host, thereby controlling the temperature of the pneumoperitoneum end tube port of the pneumoperitoneum tube to avoid the situation where the CO2 gas temperature at the pneumoperitoneum end tube port is too low or too high.

[0020] The outlet of the pneumoperitoneum machine outputs carbon dioxide gas, which is injected into the patient's body through the pneumoperitoneum tube. At the same time, the temperature of the outer wall of the pneumoperitoneum tube is sensed in real time by a temperature sensor to obtain the temperature of the carbon dioxide gas flow in the pneumoperitoneum tube, thereby indirectly sensing the temperature of the carbon dioxide entering the patient's body and reducing the surgical risk of the patient.

[0025] Preferably, the pneumoperitoneum temperature monitoring device of the pneumoperitoneum machine further comprises a primary heating tube; one end of the primary heating tube is connected to the air inlet of the pneumoperitoneum machine, and the other end is connected to the main unit of the pneumoperitoneum machine; the primary heating tube completes the preheating of the CO2 gas source, and the secondary heating tube completes the secondary heating of CO2;

The temperature control system controls the heating temperature of the secondary heating tube and the primary heating tube according to the temperature to better control the temperature of the insufflature end of the insufflature tube to avoid the situation where the CO2 gas temperature at the insufflature end is too low or too high.

[0027] The beneficial effects of the utility model are:

[0029] By setting up a heat-insulating tube and forming a gap area between the inner tube wall of the heat-insulating tube and the outer tube wall of the pneumoperitoneum tube body, the heat insulation and heat preservation functions are realized, thereby reducing the heat radiation of the pneumoperitoneum tube (reducing the heat exchange between the CO2 in the pneumoperitoneum tube and the external environment), and reducing the influence of the external environment on the CO2 temperature inside the pneumoperitoneum tube;

[0030] The temperature sensor is placed in the heat-insulating cavity, close to the outer surface of the pneumoperitoneum tube and close to the tube opening of the pneumoperitoneum end.

[0031] The utility model can prevent CO2 with too high or too low temperature from entering the human abdominal cavity, ensure that the CO2 temperature entering the human abdominal cavity through the pneumoperitoneum tube is consistent with the actual temperature of the human body, avoid fogging of the endoscope, and thus reduce the impact of CO2 temperature that is too high or too low on surgery;

[0032] The temperature sensor does not need to be placed on the inner wall of the insufflature tube, but only needs to be pasted on the outer surface of the insufflature tube. The measured temperature can directly reflect the airflow temperature inside the insufflature tube.

[0033] The temperature is adjusted through the temperature control system of the main unit of the pneumoperitoneum machine to ensure that the temperature of the pneumoperitoneum tube entering the human abdominal cavity is neither too high nor too low, so that the temperature at the pneumoperitoneum end of the pneumoperitoneum tube is basically consistent with the actual temperature of the human body;

[0040] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] Example 1

[0042] See also Figure 1-3, a pneumoperitoneum tube 1 with temperature monitoring, which includes a pneumoperitoneum tube body 2, an insulation tube 3, and a temperature sensor 4. One end of the pneumoperitoneum tube body 2 is a connecting end tube port, which is connected to the pneumoperitoneum machine outlet 8; the other end of the pneumoperitoneum tube body 2 is a pneumoperitoneum end tube port, which is placed in the human abdominal cavity 11. The insulation tube 3 is hollow and cylindrical, and is sleeved on the outside of the pneumoperitoneum tube body 2; a gap area is formed between the inner wall of the insulation tube 3 and the outer wall of the pneumoperitoneum tube body 2, wherein the thickness of the gap area is 1mm to 3mm, and the gap area is an insulation zone (insulation cavity 5); and the insulation zone is in a closed state and isolated from the external environment, that is, the insulation zone (insulation cavity 5) is a closed cavity. The insulation tube 3 realizes the functions of insulation and heat preservation, and reduces the heat exchange between CO2 in the pneumoperitoneum tube and the external environment. The temperature sensor 4 is placed in the insulation cavity 5 and close to the pneumoperitoneum end tube port. The temperature sensor 4 collects the surface temperature of the insufflature tube body 2 (the temperature of the CO2 gas flow in the insufflature tube body), and transmits the collected surface temperature of the insufflature tube body 2 to the temperature control system of the insufflature machine main unit 6.

[0043] In this embodiment, the temperature sensor 4 is an adhesive thermal resistor surface temperature sensor (using a non-porous patch temperature probe), which is tightly adhered to the outer surface of the pneumoperitoneum tube body by thermal conductive glue, and is very convenient to install.

[0044] The gas outlet 8 of the pneumoperitoneum machine outputs carbon dioxide gas, which is injected into the patient's body through the pneumoperitoneum tube. At the same time, the temperature of the outer wall surface temperature of the pneumoperitoneum tube body 2 is sensed in real time by the temperature sensor 4, thereby obtaining the temperature of the carbon dioxide gas flow in the pneumoperitoneum tube; the temperature control system of the pneumoperitoneum machine host 6 indirectly controls the temperature of the carbon dioxide gas flow at the pneumoperitoneum end of the pneumoperitoneum tube according to the temperature, thereby controlling the temperature of the carbon dioxide entering the patient's body, thereby avoiding the CO2 gas temperature at the pneumoperitoneum end being too low or too high, affecting the doctor's vision, and reducing the patient's surgical risk.

[0045] Example 2

[0046] What is different from the embodiment is that the pipe opening at the connecting end is a detachable pipe opening to facilitate installation, disassembly and storage.

[0047] Example 3

[0048] A pneumoperitoneum temperature monitoring device for a pneumoperitoneum machine, the device adopts the pneumoperitoneum tube 1 with temperature monitoring function in Example 1.

[0050] See also Figure 1-3, which is different from Example 3 in that: a pneumoperitoneum temperature monitoring device for a pneumoperitoneum machine comprises a pneumoperitoneum machine main unit 6, a secondary heating tube 7, a pneumoperitoneum machine outlet 8, and a pneumoperitoneum tube 1 with temperature monitoring. The pneumoperitoneum machine main unit 6 is connected to the pneumoperitoneum machine outlet 8 through the secondary heating tube 7; the pneumoperitoneum machine main unit 6 has a built-in temperature control system. The connecting end of the pneumoperitoneum tube 1 with temperature monitoring is connected to the pneumoperitoneum machine outlet 8, and the pneumoperitoneum end of the pneumoperitoneum tube 1 with temperature monitoring is placed in the abdominal cavity 11 of the human body; the temperature sensor 4 of the pneumoperitoneum tube 1 with temperature monitoring transmits the collected surface temperature of the pneumoperitoneum tube body 2 to the temperature control system of the pneumoperitoneum machine main unit 6 through the signal line 12. The temperature control system controls the heating temperature of the secondary heating tube 7 according to the temperature, and then controls the carbon dioxide temperature at the pneumoperitoneum end of the pneumoperitoneum tube to avoid the CO2 gas temperature at the pneumoperitoneum end being too low or too high.

[0051] Example 5

[0052] The difference from Example 4 is that the insufflature temperature monitoring device of the insufflature machine also includes a primary heating tube 9; one end of the primary heating tube 9 is connected to the insufflature machine air inlet 10, and the other end is connected to the insufflature machine main unit 6; the primary heating tube 9 completes the CO2 gas source preheating, and the secondary heating tube 7 completes the CO2 secondary heating.

[0053] The temperature sensor 4 of the pneumoperitoneum tube 1 with temperature monitoring transmits the collected surface temperature of the pneumoperitoneum tube body 2 to the temperature control system of the pneumoperitoneum machine host 6, and the temperature control system automatically controls the temperature of the primary heating tube 9 and the secondary heating tube 7, that is: the temperature control system controls the heating temperature of the secondary heating tube 7 and the primary heating tube 9 according to the temperature transmitted by the temperature sensor 4, and then controls the temperature of the pneumoperitoneum end of the pneumoperitoneum tube to avoid the CO2 gas temperature at the pneumoperitoneum end being too low or too high, and ensure that the temperature of CO2 entering the human abdominal cavity through the pneumoperitoneum tube can be basically consistent with the human body temperature.

[0054] In the present invention, once the temperature inside the pneumoperitoneum machine main unit 6 or the pneumoperitoneum tube pipeline is abnormal, the temperature control system can immediately issue an alarm and make corrections to avoid injecting CO2 gas with too low or too high a temperature into the patient's body.
