Referring to fig. 1 and 2, a ventilation therapy device according to a preferred embodiment of the present invention may be configured as a ventilator or a high flow oxygen therapy apparatus, etc., and has a main body 1 and a humidification tank 2 installed on the main body 1. The main body 1 can be provided with a mounting seat for mounting the humidification tank 2, and the humidification tank 2 can be detachably mounted on the mounting seat so as to be detached from the main body 1 for operations of adding water, cleaning and the like.
With reference to fig. 3 to 6, in the ventilation therapy device of the present invention, the main body 1 has a temperature measuring sensor 11 protruding and extending; the humidifying tank 2 is formed with a temperature measuring cavity 21. When the humidification tank 2 is installed on the host 1, the temperature measuring sensor 11 is located in the temperature measuring cavity 21. It can be understood that the temperature measuring sensor 11 protrudes outwards relative to the outer contour of the housing of the main unit 1, so as to extend into the temperature measuring cavity 21 formed on the humidification tank 2, thereby accurately measuring the temperature of the gas generated by the humidification tank 2.
From this, this treatment equipment of ventilating is through locating host computer 1 with temperature measurement sensor 11 ware, therefore does not belong to disposable consumptive material, can long-term used repeatedly, not only can not increase the cost consumption that leads to because of changing temperature measurement sensor, has still eliminated the inconsistency problem that measuring error between the different sensors brought. When the humidification tank 2 is detached from the main machine 1, the temperature measuring sensor 11 on the main machine 1 is withdrawn from the temperature measuring cavity 21, and the temperature measuring sensor 11 can be disinfected regularly as the main machine shell, so that the cost is saved.
Meanwhile, the temperature measuring cavity 21 for accommodating the temperature measuring sensor 11 is formed in the humidifying tank 2, so that the sensing element of the temperature measuring sensor 11 can sense the gas temperature accurately, and reliable data support is provided for gas temperature and humidity control.
In view of the above, the measurement of the temperature of the gases in the humidification tank 2 is primarily for the purpose of facilitating the supply of gases of a suitable temperature and humidity to the patient, and therefore the temperature sensor 11 should be arranged to measure the temperature of the gases supplied to the patient as accurately as possible. For this purpose, the temperature measuring sensor 11 and the temperature measuring chamber 21 in which it is located in the operating state may be arranged close to the air outlet of the humidification tank 2. Specifically, the humidification cylinder may have a cylinder 22, and an inlet pipe 23 and an outlet pipe 24 connected to the cylinder 22, wherein the cylinder 22 is formed with a containing cavity for containing, for example, purified water, and the inlet pipe 23 and the outlet pipe 34 respectively penetrate through the cylinder 22 to extend into the containing cavity and communicate with the containing cavity. In the assembled state as shown in fig. 1 and 2, the inlet tube 23 may be connected to a corresponding portion of the main unit 1, so that the air is introduced into the accommodating chamber through the inlet tube 23, humidified in the accommodating chamber, and then delivered to the patient through the outlet tube 24. In this case, the temperature measuring chamber 21 may be formed at a position close to the outlet pipe 24, such as an adapter pipe 25 connected to the outlet pipe 24 as described later.
In order to facilitate connection of the breathing pipeline so as to deliver the heated and humidified breathing gas to the patient, the air outlet pipe 24 may be connected with a switching pipe 25, and the switching pipe 25 may be bent relative to the extending direction of the air outlet pipe 24 so as to connect the breathing pipeline at a proper angle and deliver the gas with proper temperature and humidity to the patient through a breathing mask and the like. In the preferred embodiment shown, the inlet pipe 23 is integrally connected to the outlet pipe 24 and can be attached to or detached from the tank 22 together with the adapter pipe 25. As shown in fig. 5 and 6, the adapter tube 25 has a gas passage surrounded by side walls and a gas outlet at an end of the gas passage remote from the gas outlet tube 24, and the temperature measuring chamber 21 is formed on the side wall of the adapter tube 25 so as to be able to relatively accurately measure the temperature of the expiratory gas supplied to the patient through the breathing tube connected to the adapter tube 25.
In order to avoid contamination of the temperature measuring sensor 11 after use, for subsequent reuse after simple sterilization, the temperature measuring chamber 21 can be arranged so as to be isolated from the gas passage of the adapter tube 25. For this purpose, the end of the temperature detector 21 facing the gas channel can be closed.
In the illustrated embodiment, the outlet of the adapter tube 25 is directed vertically upwards and is disposed adjacent to the tubing socket of the host 1. An adapter tube positioning groove 12 is formed near the pipeline socket of the host 1, and the temperature sensor 11 extends in the adapter tube positioning groove 12 along the horizontal direction. Therefore, when the humidification tank 2 is installed on the host 1, the adapter tube 25 is positioned in the adapter tube positioning groove 12, the breathing pipeline can be connected to the adapter tube 25 on the upper side of the host 1, and in the installation state, the temperature measuring sensor 11 extends into the temperature measuring cavity 21 formed on the side wall of the adapter tube 25.
In the process of mounting the humidification tank 2 on the main machine 1, the humidification tank 2 is usually pushed in the horizontal direction, so that the air inlet pipe 23 and the air outlet pipe 24 of the humidification tank 2 are jointed with the corresponding parts of the main machine 1, and the adapter pipe 15 is positioned in the adapter pipe positioning groove 12. The adapter tube 25 may have a horizontally extending section for interfacing with the horizontally extending outlet tube 24 and a vertically extending section vertically extending upward from the horizontally extending section, wherein the temperature measuring chamber 21 may be formed at a bottom wall portion of the horizontally extending section adjacent to the vertically extending section, whereby the temperature measuring sensor 11 may have a relatively sufficient extension space and be located at a relatively low position on the main unit 1, reducing the risk of damage due to an accidental collision.
The temperature sensor 11 may be fixed to the housing of the main unit 1 in a variety of suitable ways. For example, the temperature sensor 11 may be fixed by pressing a pressing plate and a screw fastener, or may be fixed to the housing by gluing, fastening, or the like.

In order to ensure the strength, the wire can be coated with glue. The encapsulated outer profile shape can be cylindrical or prismatic, preferably cylindrical, for ease of assembly and better sealing. The outer contour dimension of the temperature sensor 11 is basically equivalent to the inner contour dimension of the temperature measuring cavity 21, for example, when the outer contour of the temperature sensor 11 is formed into a cylindrical shape, the outer diameter of the temperature sensor can be slightly smaller than the inner diameter of the temperature measuring cavity 21, therefore, in an assembly state, the encapsulated part is in sealing contact with the inner wall surface of the temperature measuring cavity 21, the sensing element is sealed in the temperature measuring cavity 21, the part of the temperature sensor 11 with the sensing element is conveniently inserted into the temperature measuring cavity 21, and the sealing effect is good, after a certain time, the temperature sensed by the sensing element on the temperature sensor 11 is the same as the temperature of the gas conveyed in the adapter pipe 25 of the humidification tank 2 through heat transfer, and therefore the purpose of accurate measurement is achieved.
