Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically, to an oxygen inhalation device for tracheostomy patients. Background Technology

[0002] In the medical field, during the treatment of patients, tracheotomy patients cannot use ordinary mask oxygen supply due to the change in their breathing channel. Therefore, special oxygen inhalation devices must be used, but there are still some defects in the current oxygen inhalation devices.

[0003] Currently, venturi devices are commonly used for oxygen administration. Compared to a regular face mask, they can ultimately provide patients with a higher inspiratory flow rate. On one hand, when the provided flow rate exceeds the patient's peak inspiratory flow rate, the patient will not inhale ambient air, thus ensuring a stable and precisely controllable oxygen concentration. On the other hand, the high-flow-rate gas can have a certain flushing effect on the patient's exhaled air, preventing rebreathing. However, at the same time, the high-flow-rate airflow may also bring some "side effects," such as causing airway mucosal dryness and thickened sputum.

[0004] Therefore, we have made improvements to this and proposed an oxygen inhalation device for tracheostomy patients. Utility Model Content

[0005] The purpose of this invention is to address the problems of airway mucosa dryness and viscous sputum caused by high-flow-rate air.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] Tracheostomy patients are given oxygen therapy devices to alleviate the above problems.

[0008] The specific details of this utility model are as follows:

[0009] It includes a ventilator tubing and an air inlet, with one end of the ventilator tubing connected to an oxygen supply device.

[0010] The oxygen inhalation device includes an adjustment head and a humidification tank. The adjustment head includes a fixed head, a rotating head, an adjustment groove, an inlet, and a tubing. The fixed head is connected to one end of the ventilator tubing. The rotating head is snapped onto the fixed head at the end away from the ventilator tubing and can rotate on the fixed head. The adjustment groove is located at the overlapping part of the fixed head and the rotating head and is in the shape of a quarter-circle arc. The two sets of adjustment grooves are staggered. The inlet is located at the bottom end of the fixed head. The tubing is located inside the rotating head and its end cooperates with the inlet. The humidification tank is connected to one end of the adjustment head through the ventilator tubing.

[0011] As a preferred technical solution of this utility model, a positioning groove is provided in the middle section of the fixed head, and a positioning block is fixedly provided on the side wall of the rotating head, and the positioning grooves can correspond to each other.

[0012] As a preferred technical solution of this utility model, the side wall of the fixing head is provided with scale markings.

[0013] As a preferred technical solution of this utility model, the other end of the humidification tank is connected to the tracheostomy sleeve, and a 500ml sterile water for injection infusion set is connected to the humidification tank.

[0014] As a preferred technical solution of this utility model, the oxygen inhalation device, including the adjustment head, humidification tank and ventilator tubing, is made of medical-grade plastic.

[0015] As a preferred technical solution of this utility model, the ventilator tubing is a corrugated pipe that can be stretched and changed in length.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the solution of this utility model:

[0018] The oxygen inhalation device creates negative pressure around the regulating head when oxygen enters through the narrow air inlet channel. This pressure carries a certain amount of air into the mask from the open edge of the regulating head, drawing in the surrounding air to form a high-flow-rate air-oxygen mixture. This allows for precise control of the oxygen concentration. Before entering the humidification tank, the oxygen concentration can be adjusted via the regulating head. The oxygen is then humidified in the humidification tank, providing a higher flow rate to deliver humidified oxygen to the airway. The humidification level can be adjusted according to the viscosity of the patient's sputum. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] like Figure 1-5 As shown, this embodiment proposes an oxygen inhalation device for tracheostomy patients, including a ventilator tubing 1 and an air inlet 6, with an oxygen inhalation device 2 connected to one end of the ventilator tubing 1.

[0031] like Figure 4 and Figure 5As shown, the oxygen inhalation device 2 includes an adjustment head 201 and a humidification tank 203. The adjustment head 201 includes a fixed head 2011, a rotating head 2012, an adjustment groove 2013, an inlet 2014, and an intubation tube 2015. The fixed head 2011 is connected to one end of the ventilator tubing 1. The rotating head 2012 is snapped onto the fixed head 2011 at the end away from the ventilator tubing 1, and the rotating head 2012 can rotate on the fixed head 2011. The adjustment groove 2013 is opened in the overlapping part of the fixed head 2011 and the rotating head 2012, and the adjustment groove 2013 is a quarter-circle arc shape. The two sets of adjustment grooves 2013 are staggered. The inlet 2014 is opened at the bottom end of the fixed head 2011. The intubation tube 2015 is located inside the rotating head 2012, and one end cooperates with the inlet 2014. The humidification tank 203 is connected to one end of the adjustment head 201 through the ventilator tubing 1. The rotating head 2012 is inserted into the fixed head 2011. As oxygen passes through the adjusting head 201, the rotating head 2012 is adjusted according to the patient's condition, changing the position between the adjusting groove 2013 on the rotating head 2012 and the adjusting groove 2013 on the fixed head 2011. This alters the gap between the fixed head 2011 and the rotating head 2012. Pure oxygen enters the adjusting head 201 through the narrow air inlet channel 6. Because the diameter of the air inlet channel 6 is small, smaller than the diameter of the subsequent ventilator tubing 1, one end of the air inlet channel 6 located inside the adjusting head 201 is connected to the intubation tube 2015. Furthermore, both have the same inner diameter. When the fluid passes through the narrowed cross-section, the fluid velocity increases. The velocity is inversely proportional to the cross-section. According to Bernoulli's law, the increase in velocity is accompanied by a decrease in fluid pressure, which is the common Venturi phenomenon. That is, a low pressure is generated near the outlet of the high-speed flowing fluid (air inlet 6), which produces an adsorption effect. This creates a negative pressure around the regulating tank 2013, carrying a certain amount of air from the edge of the open regulating tank 2013 into the mask, encircling the surrounding air to form a high-flow-rate air-oxygen mixture, which can precisely control the oxygen concentration.

[0032] like Figure 4 As shown, a positioning groove 3 is provided in the middle section of the fixed head 2011, and a positioning block 4 is fixedly provided on the side wall of the rotating head 2012. The positioning grooves 3 can correspond to each other. The positioning block 4 and the positioning groove 3 are locked together to determine the position of the rotating head 2012 on the fixed head 2011.

[0033] like Figure 4 As shown, the fixed head 2011 has a scale mark 5 on its side wall. The scale mark 5 indirectly indicates the relationship between the rotation arc and the oxygen concentration, making it convenient for medical staff to adjust and use.

[0034] like Figure 2As shown, the other end of the humidification tank 203 is connected to the tracheostomy cannula, and 500ml of sterile water for injection is connected to the humidification tank 203 via an infusion set. The humidification tank 203 can be opened to add saline or nebulized medication.

[0035] like Figure 1 As shown, the oxygen inhalation device 2, including the adjustment head 201, humidifier tank 203, and ventilator tubing 1, is made of medical-grade plastic.

[0036] like Figure 1 As shown, the ventilator tubing 1 is a retractable, variable-length corrugated tube. This allows for easy adjustment of the length during use.

[0037] Specifically, when using the oxygen inhalation device for tracheostomy patients: connect the ventilator and humidifier 203; connect 500ml of sterile water for injection to the humidifier 203 using an infusion set; the humidifier 203 can be opened to add saline or nebulized medication; oxygen enters through the regulating head 201, passes through the humidifier 203, and then through the subsequent tracheostomy cannula; during adjustment, insert the rotating head 2012 into the fixed head 2011; as oxygen passes through the regulating head 201, adjust the rotating head 2012 according to the patient's condition to change the rotation... The position between the adjustment groove 2013 on the head 2012 and the adjustment groove 2013 on the fixed head 2011 changes the gap between the fixed head 2011 and the rotating head 2012. When oxygen enters the adjustment head 201 through the narrow air inlet 6, a negative pressure is generated around the adjustment groove 2013, carrying a certain amount of air from the edge of the open adjustment groove 2013 into the mask, encircling the surrounding air to form a high-flow-rate air-oxygen mixture, which can precisely control the oxygen concentration and adjust it to the corresponding oxygen flow rate and concentration.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
