Description

Technical Field

[0001] The utility model belongs to the field of oxygen inhalation equipment, and in particular relates to a constant temperature humidification oxygen inhalation device used after nose surgery. Background Art

[0002] After nasal surgery, general anesthesia or surgical trauma may affect the patient's normal breathing. In order to avoid hypoxia and decreased blood oxygen saturation caused by dyspnea, appropriate oxygen therapy can be given according to the patient's own experience. Existing nasal cannula oxygen inhalation devices mainly include oxygen supply equipment such as oxygen cylinders and oxygen supply machines, flow meters, humidification bottles and nasal cannulas. Among them, the function of the humidification bottle is to humidify the passing oxygen.

[0003] However, the existing humidification bottle has a simple structure, and the humidification method is only to inject oxygen into the sterile distilled water in the humidification bottle. The humidification effect is determined by the contact time between oxygen and sterile distilled water. Under natural conditions, oxygen will overflow from the sterile distilled water disorderly and quickly, so there is a problem of weak and unstable humidification effect, and the existing nasal catheter oxygen inhalation device cannot adjust the temperature of the delivered oxygen. In view of the above problems, the utility model provides a constant temperature humidification oxygen inhalation device for nasal surgery. Utility Model Content

[0004] The purpose of the utility model is to provide a constant temperature humidification oxygen inhalation device for post-nasal surgery in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

The air inlet end of the air inlet pipe is connected with the flow meter. A hollow water absorption pipe is arranged in the humidification bottle. The air inlet end of the hollow water absorption pipe is connected with the air outlet end of the air inlet pipe through a connecting pipe, and the connecting pipe runs through the bottom of the humidification bottle. A floating ball is arranged on the air outlet end of the hollow water absorption pipe, and the air outlet port is immersed in sterile distilled water. The oxygen supply tube is connected with the air outlet end of the humidification bottle. A heating mechanism is detachably arranged on the oxygen supply tube. The oxygen supply tube is used for externally connecting oxygen output components.

[0007] As a further optimization solution of the utility model, the heating mechanism includes a shell, a heating plate is arranged inside the shell, and a power supply and a control module thereof are detachably connected to the shell.

[0008] As a further optimization scheme of the utility model, the inner expansion profile of the shell is an arc-shaped structure that fits the outer contour of the oxygen supply tube, and two clamping pieces in an inverted eight-shaped structure are provided under the shell. The clamping pieces cooperate with the shell to clamp the oxygen supply tube, and the clamping pieces are made of elastic metal sheets.

[0009] As a further optimization solution of the utility model, the hollow water suction pipe is a spiral structure.

[0010] As a further optimization solution of the utility model, the connecting pipe and the humidification bottle as well as the connecting pipe and the air inlet pipe are all sealed and rotatably connected.

[0011] As a further optimization solution of the utility model, the oxygen output component externally connected to the oxygen supply tube can be a nasal catheter or an oxygen mask.

[0012] The beneficial effects of the utility model are:

[0013] 1. By adding a connecting pipe, an air duct and a floating ball in the humidification bottle, the effect of directional guidance of oxygen flow is achieved, so that the oxygen can fully absorb water in the process of flowing along the air duct, achieving a stable and effective humidification effect.

[0014] 2. By setting a heating mechanism that can be detachably sleeved on the oxygen supply tube, the effect of heating and raising the temperature of the oxygen passing through the heating range is achieved.

[0021] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1-5 As shown, the constant temperature humidification oxygen inhalation device for postoperative nasal surgery of this embodiment comprises an oxygen supply device 3, a flow meter 2, a humidification bottle 1 and an oxygen supply tube 4 which are connected in sequence. The humidification bottle 1 is used to contain sterile distilled water. An air inlet pipe 9 is provided on the outside of the humidification bottle 1. The air inlet end of the air inlet pipe 9 is connected with the flow meter 2. A hollow water absorption pipe 6 is provided in the humidification bottle 1. The air inlet end of the hollow water absorption pipe 6 is connected with the air outlet end of the air inlet pipe 9 through a connecting pipe 8, and the connecting pipe 8 passes through the bottom of the humidification bottle 1. A floating ball 7 is provided on the air outlet end of the hollow water absorption pipe 6, and the air outlet port is immersed in sterile distilled water. The oxygen supply tube 4 is connected with the air outlet end of the humidification bottle 1. A heating mechanism 5 is detachably provided on the oxygen supply tube 4. The oxygen supply tube 4 is used for external oxygen output components.

[0024] After being output from the oxygen supply device 3, the oxygen flows through the flow meter 2, the humidification bottle 1 and the oxygen delivery tube 4 in sequence and then enters the patient's nasal cavity. In the process of flowing through the humidification bottle 1, the oxygen will pass through the hollow water suction tube 6, and one end of the hollow water suction tube 6 is fixed on the connecting pipe 8, and the other end is always in a position just immersed in the sterile distilled water under the action of the float 7. Therefore, the hollow water suction tube 6 is always located in the sterile distilled water as a whole, and the hollow water suction tube 6 is always in a state of being completely soaked. When oxygen passes through the hollow water suction tube 6, it can be The side wall of the hollow water absorption tube 6 absorbs water to achieve a humidification effect. The hollow water absorption tube 6 plays an effect of directional guiding the flow of oxygen during the humidification process, effectively prolonging and stabilizing the contact time between oxygen and sterile distilled water, and achieving a significant and stable humidification effect. The heating mechanism 5 can be put on any part of the oxygen supply tube 4 and can be freely disassembled, which is convenient for repeated use. The temperature of the oxygen output by the oxygen supply tube 4 can be adjusted by adjusting the distance between the heating mechanism 5 and the output end of the oxygen supply tube 4. The heating effect is flexible and highly practical.

[0025] The heating mechanism 5 includes a shell 501, in which a heating plate 503 is arranged, and a power supply and a control module 502 thereof are detachably connected to the shell 501. The heating plate 503 heats up the shell 501, and then heats the part of the oxygen supply tube 4 that is in contact with the shell 501 and the oxygen passing therethrough. The heating effect of the heating plate 503 can be adjusted according to the ambient temperature.

[0026] The inner expansion profile of the shell 501 is an arc-shaped structure that fits the outer contour of the oxygen supply tube 4, and two clamping pieces 504 with an inverted eight-shaped structure are provided below the shell 501. The clamping pieces 504 cooperate with the shell 501 to clamp the oxygen supply tube 4. The clamping pieces 504 are made of elastic metal sheets. The heating mechanism 5 can be loaded and unloaded by pushing the two clamping pieces 504 outward, which is convenient and efficient to operate.

[0027] The hollow water suction pipe 6 is a spiral structure, and its material can be selected from sponge, cotton, bamboo fiber, etc. The hollow water suction pipe 6 with a spiral structure has a long path and the pitch can naturally decrease as the liquid level decreases.

[0028] The connecting pipe 8 and the humidification bottle 1 as well as the connecting pipe 8 and the air inlet pipe 9 are all sealed and rotatably connected. The connecting pipe 8 can rotate naturally following the shaking of the hollow water absorption pipe 6, thereby avoiding the problem of partial folding of the hollow water absorption pipe 6 and hindering gas transmission.

[0029] The oxygen output component external to the oxygen supply tube 4 can be a nasal catheter or an oxygen mask (not shown in the drawings of the specification). The nasal catheter is more comfortable to wear and more commonly used, and the oxygen mask is better at maintaining constant temperature and humidification. It can be selected according to actual conditions.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
