Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a temperature and humidity management device inside a ventilator pipeline. Background Art

[0002] In modern clinical medicine, as an effective means to artificially replace the function of autonomous ventilation, ventilators have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgeries, respiratory support treatment, and first aid resuscitation, and occupy a very important position in the field of modern medicine. A ventilator is a crucial medical device that can prevent and treat respiratory failure, reduce complications, and save and extend the lives of patients.

[0003] As an essential accessory of a ventilator, the ventilator pipeline is used with each ventilator. The inventor of this application also found through research that, as an ordinary ventilator pipeline, in use, on the one hand, due to the certain length of the ventilator pipeline, when the external environmental temperature is relatively low, it will affect the temperature inside the ventilator pipeline. Specifically, the gas inside the ventilator pipeline will be cooled rapidly under the action of water molecules after humidification and heating, resulting in the problem of pipeline condensate, so that it is impossible to ensure that the gas reaches the mask at an appropriate temperature and humidity, which is not conducive to the use of patients. If a heating device is directly installed outside the ventilator pipeline, when the heating device is damaged due to long-term use or the internal pipeline of the heating device is damaged, it is not convenient for personnel to repair the heating device or disassemble the heating device to replace the internal pipeline, which is not convenient for personnel to operate. On the other hand, at present, it is rare to monitor the temperature and humidity of the gas close to the mask, that is, close to the ventilator side, after humidification and heating inside the ventilator pipeline, so that it is impossible to adjust the temperature of the gas after humidification and heating in the humidification tank, resulting in easy water accumulation inside the ventilator pipeline during use, reducing the comfort of ventilator patients, increasing ventilator-related complications and the loss of ventilator instruments, and thus prolonging the tracheal intubation time and hospitalization duration of patients. Summary of the Utility Model

[0004] Aiming at the technical problems that the external environmental temperature will affect the temperature inside the ventilator pipeline during the use of the existing ventilator, and it is rare to monitor the temperature and humidity of the gas close to the ventilator side after humidification and heating inside the ventilator pipeline, the utility model provides a temperature and humidity management device inside a ventilator pipeline.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An internal temperature and humidity management device for a ventilator pipeline, comprising a humidifying and heating base, a heat preservation sheath for the ventilator pipeline, and a temperature and humidity monitor for the ventilator pipeline. The humidifying and heating base is suitable for fixedly heating a humidifying tank. A first data processor is arranged inside the humidifying and heating base. A temperature display screen, a temperature adjustment key, a heating switch, and a first data line interface electrically connected to the first data processor are arranged on the outer surface of the humidifying and heating base. The heat preservation sheath for the ventilator pipeline is sleeved on the ventilator pipeline connecting the humidifying tank and the ventilator. The heat preservation sheath for the ventilator pipeline comprises a polyester fiber outer sleeve and a heat preservation layer. The heat preservation layer is detachably arranged inside the polyester fiber outer sleeve. The heat preservation layer is composed of a high-density rubber plate, a polyester aluminized film, and a polyvinyl chloride film from the inside out. A second data processor is arranged inside the temperature and humidity monitor for the ventilator pipeline. A temperature and humidity display screen, an intelligent temperature control key, a temperature control key, a monitor switch, a second data line interface, and a temperature and humidity probe electrically connected to the first data processor are arranged on the outer surface of the temperature and humidity monitor for the ventilator pipeline. The second data line interface and the first data line interface are connected through a data line. The temperature and humidity probe is tightly inserted into the ventilator pipeline near the ventilator side.

[0007] Compared with the prior art, the internal temperature and humidity management device for a ventilator pipeline provided by the utility model, on the one hand, sleeves a ventilator pipeline heat preservation sheath on the ventilator pipeline. The ventilator pipeline heat preservation sheath is composed of a polyester fiber outer sleeve and a heat preservation layer that can be detachably arranged inside the polyester fiber outer sleeve. The heat preservation layer is composed of a high-density rubber plate, a polyester aluminized film, and a polyvinyl chloride film from the inside out. Among them, the high-density rubber plate and the polyester aluminized film can effectively isolate the external environment temperature, minimizing the influence of the external environment temperature on the internal temperature of the ventilator pipeline. The polyvinyl chloride film has airtightness, has good waterproof effect and certain antibacterial ability, and has good resistance and can be repeatedly disinfected and used, which can effectively prevent the colonization of multi-drug-resistant bacteria and prevent bacterial cross-infection. And the polyester fiber outer sleeve and the heat preservation layer can be separated, making it more convenient to clean and disinfect. On the other hand, by setting a ventilator pipeline temperature and humidity monitor and a humidifying and heating base, the temperature and humidity probe on the ventilator pipeline temperature and humidity monitor is inserted into the ventilator pipeline near the ventilator side. Thus, the temperature and humidity of the humidified and heated gas inside the ventilator pipeline can be effectively monitored and displayed through the temperature and humidity display screen. When it is detected that the temperature of the gas inside the ventilator pipeline is lower than the preset temperature, press the intelligent temperature control key on the ventilator pipeline temperature and humidity monitor, and the second data processor will automatically transmit the difference signal between the temperature of the gas inside the ventilator pipeline and the preset temperature to the first data processor through the data line. The first data processor automatically adjusts the temperature of the existing electric heating components inside the humidifying and heating base for heating according to this signal, so as to achieve information sharing and thus realize intelligent temperature and humidity control; of course, a manual control method can also be executed. Specifically, when it is detected that the temperature of the gas inside the ventilator pipeline is lower than the preset temperature, input the difference between the temperature of the gas inside the ventilator pipeline and the preset temperature through the temperature control key on the ventilator pipeline temperature and humidity monitor, and the second data processor transmits this difference signal to the first data processor through the data line, and it can also realize the humidifying and heating base to adjust the temperature for heating according to the data of the ventilator pipeline temperature and humidity monitor. Accordingly, during the use of the ventilator adopting this device, it can more simply and objectively monitor the internal temperature and humidity of the ventilator pipeline, more effectively control the internal temperature and humidity of the ventilator pipeline, reduce the influence of the external environment temperature on the ventilator, reduce the water accumulation in the ventilator pipeline, reduce the incidence probability of ventilator-related complications, and thus shorten the tracheal intubation time, hospitalization duration, and medical expenses of patients.
