Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a ventilator structure. Background Art

[0002] A ventilator is a device that can replace, control or change a person's normal physiological breathing process. It aims to increase lung ventilation, improve respiratory function, reduce the energy consumption required for breathing, and save heart reserve capacity.

[0003] With the development of medical technology, the functions of ventilators are becoming increasingly rich. The rise of intelligent medical technology has promoted the data collection and connection capabilities of ventilators. By installing various interfaces on the ventilator, real-time uploading of patient monitoring data is achieved. In this way, medical staff can monitor the health status of patients in real time. In addition, the safety of the ventilator is further improved through continuous monitoring of the ventilator and combined with various sensors installed on the ventilator (such as temperature sensors, pressure sensors, and various gas flow meters, etc.).

[0004] The multi-function makes the internal space of the ventilator very compact. High-heat generating components such as the power supply and mainboard and ventilation components are concentrated inside the ventilator.

The main heat-generating electronic components of the power module 21 are installed on the substrate away from the partition plate 14, and the main heat-generating electronic components of the mainboard control module 22 are installed on the substrate facing the partition plate 14.

[0036] The partition plate 14 divides the chamber of the housing 1 into an upper mounting chamber 11 and a lower mounting chamber 12, and each circuit module of the ventilator is respectively installed in the upper mounting chamber 11 and the lower mounting chamber 12 in a three-dimensional manner. The ventilation component 3 is arranged below the mainboard control module 22 and part of the ventilation component 3 is installed on the side of the upper mounting chamber 11, which can not only optimize the structural layout inside the housing 1, so that the arrangement of each component occupies less space, which is conducive to the overall miniaturization design of the ventilator, but also the power module 21, the mainboard control module 22, and the auxiliary function module ventilation component 3 are distributed in different three-dimensional space positions, not a simple stacking layout, the ventilation component 3 does not hinder the heat dissipation channel, leaving enough heat dissipation space and smooth heat dissipation channel, reducing the radiation heat transfer and timely heat transfer between each circuit module when working. A gas flow channel is provided between the upper mounting chamber 11 and the lower mounting chamber 12 and between the housing 1 and the outside world, and the heat in the chamber of the housing 1 is transferred to the outside of the housing, so as to avoid the local temperature being too high and affecting the normal use of the ventilator, and improve the life of the ventilator.

[0037] See also Figure 4 and Figure 6 Furthermore, a first support column 111 is provided in the upper installation cavity 11, and the mainboard control module 22 is installed on the first support column 111. Specifically, a plurality of first support columns 111 of equal height are provided on the upper surface of the partition plate 14. The number and position of the first support columns 111 are used in conjunction with the circuit substrate positioning holes of the mainboard control module 22. By keeping a certain distance between the first support columns 111 and the partition plate 14, not only a space for the heat dissipation flow channel of the mainboard control module 22 is formed, but also the ventilation component 3 is conveniently installed in the space.

[0039] See also Figure 1 , Figure 2 and Figure 5, further, the circuit structure 2 also includes a USB interface 23, a communication interface 24 and a power input interface 25 arranged on the side wall of the housing 1, and matching sockets are provided on the power module 21 and the mainboard control module 22, and the USB interface 23, the communication interface 24 and the power input interface 25 are respectively connected to the corresponding sockets with a transfer line 26.

[0040] See also Figure 1 and Figure 3 Furthermore, the housing 1 also includes a display screen side cover 18, and the auxiliary function module includes a display screen circuit module 27.

Specifically, the display screen side cover 18 is installed on the outer side of the housing 11 at a prefabricated angle. A third support column 181 is provided on the inner wall of the display screen side cover 18. The number and position of the third support column 181 are used in conjunction with the substrate positioning hole of the display screen circuit module 27. By using the third support column 181, there is a gap between the display screen circuit module 27 and the display screen side cover 18, which helps the electronic components on the display screen circuit module 27 to dissipate heat. The main control module 22 and the display screen circuit module 27 are set at a prefabricated angle and installed in a three-dimensional manner, which not only helps the display screen circuit module 27 and the display screen 4 to dissipate heat when working, but also saves installation space, thereby contributing to the overall miniaturization of the ventilator.

[0041] See also Figure 1 and Figure 3 Furthermore, the display screen side cover 18 is provided with an extension portion 182, and the auxiliary function module also includes an indicator light circuit module 28, which is installed on the inner wall of the extension portion 182, and the indicator light circuit module 28 and the display screen circuit module 27 are arranged at a prefabricated angle.

[0042] See also Figure 6, further, the ventilation component 3 includes an oxygen supply branch 31, an air supply branch 32, an air-oxygen mixing pipe 33 and an air-oxygen output branch 34, and the ventilation component 3 is E-shaped in appearance, the oxygen supply branch 31 and the air supply branch 32 are connected to one end of the air-oxygen mixing pipe 33, and one end of the air-oxygen output branch 34 is connected to the air-oxygen mixing pipe 33, and the air supply branch 32, the air-oxygen mixing pipe 33 and the air-oxygen output branch 34 are installed along the circumferential inner wall of the upper installation cavity 11.

With this structure, the various components of the ventilation component 3 are installed in the upper installation cavity 11 in an orderly manner, which is conducive to the smooth heat dissipation flow channel in the upper installation cavity 11. The oxygen supply branch 31 includes a high-pressure proportional valve 311, a first flowmeter 312 and an oxygen passage 313; the high-pressure proportional valve 311 is connected to an external oxygen supply device to control the oxygen inlet ratio; the first flowmeter 312 is installed in the oxygen passage 313.

One end of the air-oxygen mixing passage 33 is connected to the oxygen passage 313 and the air passage 322 respectively, and the other end is connected to the air-oxygen output branch 34. The oxygen supply branch 31 and the air supply branch 32 are independently set, and can be buffered and adjusted separately, and their parameters can be monitored separately, so that the staff can adjust the oxygen flow of the oxygen supply branch and the air flow of the air supply branch with high precision, so as to achieve accurate control of the output flow and oxygen concentration. Using the air-oxygen mixing tube 33 to replace the conventional air-oxygen mixer not only saves material costs, but also reduces the size of the ventilator. Preferably, the tube of the ventilation component 3 is made of plastic material with good thermal conductivity. When each circuit module is working, part of the heat generated by the electronic components is transmitted to the tube of the ventilation component 3, and the heat is dissipated along the airflow in the tube, which plays an auxiliary heat dissipation role.

[0043] See also Figure 4 and Figure 6 , further, it also includes a fan 5, which is installed in the upper installation cavity 11; a first ventilation groove 16 that cooperates with the fan 5 is provided on one side of the housing 1. Specifically, a fan 5 is provided in the ventilator, and a sinking groove 113 connected to the first ventilation groove 16 is provided in the upper installation cavity 11, and the fan is installed in the sinking groove 113. When working, the fan 5 uses the principle of air flow to suck the outside air from the first ventilation groove 16 into the inside of the fan 5, and after the fan 5 is accelerated and turned, the cold air is discharged, and the gas with a relatively high temperature inside the ventilator is discharged, so that the housing can achieve the effect of ventilation.

A second ventilation groove 141 and a third ventilation groove 142 are provided to allow air to flow between the upper mounting cavity 11 and the lower mounting cavity 12 to form a gas circulation channel. A fourth ventilation groove 131 and a first ventilation groove 16 are provided to form a gas circulation channel between the inner cavity of the shell 1 and the outside. Then, a fan 5 is used to discharge the relatively high temperature gas in the upper mounting cavity 11 and the lower mounting cavity 12 out of the ventilator, so that the circuit assembly board of the ventilator has good heat dissipation, avoids excessive local temperature affecting the normal use of the ventilator, and increases the life of the ventilator.
