Description

Technical Field

[0001] The utility model belongs to the technical field of atomizing oxygen inhalation masks, and in particular relates to a liquid adding device for an atomizing mask. Background Art

[0002] The Chinese utility model application number is 2019220541111, which discloses an atomizing oxygen inhalation device. By setting a specific structure, the warming cup containing the medicine solution can be fixed in the placement slot, and it is convenient for the staff to replace it.

[0003] For the above-mentioned atomizing oxygen inhalation device, when the patient uses the atomizing oxygen inhalation mask, the atomizing liquid outlet is connected to the patient's tracheotomy, and the warming cup should be replaced as frequently as possible to indirectly cause the tracheotomy to be touched. And the structure of the entire atomizing device containing the liquid medicine should be simple, so as to facilitate clinical application.

[0004] Therefore, in the current clinical treatment process, the liquid in the liquid cup is replenished by piercing the infusion tube connected to the liquid cup with a syringe. However, frequent puncture of the infusion tube is likely to cause it to break and leak, and may introduce the risk of bacterial contamination. Therefore, how to complete the replenishment of the liquid in the liquid cup in a closed environment is an urgent problem to be solved by the staff. Utility Model Content

[0005] The utility model aims to provide a liquid-filling device for an atomizing mask, which has the advantages of simple and convenient liquid filling, no liquid leakage, and a liquid filling environment that is not easily contaminated by pathogens.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A liquid-filling device for an atomizing mask comprises a liquid cup for containing liquid medicine and an atomizing head, wherein the liquid cup and the atomizing head are screwed and fixed. At the same time, the liquid-filling device for an atomizing mask also comprises a telescopic hose and a liquid inlet pipe; a liquid inlet channel is provided on the atomizing head, one end of the telescopic hose is connected to the upper end of the liquid inlet channel, and the liquid inlet pipe is connected to the lower end of the liquid inlet channel; a flow guide is obliquely provided on the liquid inlet pipe, the upper end of the flow guide is close to the inner side wall of the liquid cup, and the lower end of the flow guide is away from the inner side wall of the liquid cup.

[0008] Working principle of liquid cup and atomizer head:

[0009] The atomizer head adopts the existing design and can be purchased. The atomizer head and the liquid cup are screwed together. First, it is convenient to disassemble it, and second, it can prevent the liquid in the liquid cup from flowing out.

[0010] Working principle of telescopic hose and liquid inlet pipe:

[0011] The telescopic hose is a corrugated tube, which can be adjusted by the staff according to the actual situation, such as the position of the liquid cup or the posture of the patient when using it, so as to be more convenient to use. At the same time, the liquid inlet pipe can drain the liquid medicine into the liquid cup. The liquid medicine flows down through the side wall of the liquid cup, and its opening side faces the side wall of the liquid cup, and the opening angle is also increased obliquely, which is conducive to the discharge of liquid and avoids the impact on the side wall of the liquid cup when the liquid flows down, causing it to shake.

[0012] Preferably, the inner side of the opening end of the liquid cup is provided with a thread, and correspondingly, the side end of the atomizing head is provided with a threaded section. The advantages of the threaded connection are that it is easy to disassemble, and the connection strength is high, and the liquid medicine is not easy to leak out from the connection between the two.

[0013] Preferably, the outlet of the guide part is located near the inner wall of the liquid cup. The advantage of this arrangement is that it prevents the liquid medicine from directly impacting the liquid surface in the liquid cup, causing the liquid medicine to splash and adhere to the surrounding wall of the liquid cup, resulting in waste. The liquid medicine is slowly guided into the liquid cup by the guide part, which also buffers the flow rate of the liquid medicine.

[0014] Preferably, the atomizing mask liquid adding device further comprises a liquid inlet capillary tube and a liquid stopper, wherein the liquid inlet capillary tube is detachably connected to the telescopic hose, and the liquid stopper is mounted on the liquid inlet capillary tube.

[0015] Preferably, a threaded seat is installed at the end of the liquid inlet tube, and a threaded section is provided at one end of the telescopic hose facing away from the atomizing head and is screwed and fixed to the threaded seat.

[0016] In the prior art, the staff directly pierces the liquid inlet tube with a syringe to infuse the liquid into the liquid cup. In the present application, the liquid inlet tube and the atomizer head are arranged in a screw connection, which makes it more convenient to disassemble, replace and clean.

[0017] Preferably, the liquid stopper comprises a hollow sliding seat and a clamping column, wherein the sliding seat is sleeved on the liquid inlet tube, the sliding seat is provided with a fixed threaded hole, and correspondingly, the outer wall of the clamping column is provided with threads, and the clamping column is threadedly arranged in the fixed threaded hole.

[0018] Working principle of liquid stopper:

[0019] When it is necessary to reduce the flow rate of the liquid or stop adding liquid to the liquid cup, the clamping column can be rotated to compress the liquid inlet capillary tube at its end. The liquid inlet capillary tube is deformed after being compressed, and its internal volume is reduced, so that the amount of liquid passing through gradually decreases until the addition of liquid is completely stopped.

[0020] Preferably, a plug-in collar is provided at the upper end of the atomizer head, and correspondingly, the liquid outlet pipe is plugged and fixed on the plug-in collar.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. The liquid medicine is transported into the liquid cup through the liquid inlet tube, so that the entire liquid infusion is completely in a closed environment to avoid contamination by miscellaneous bacteria.

[0023] 2. The liquid medicine is transported into the liquid cup through the liquid inlet tube, and there is no need to puncture the infusion tube again to replenish the liquid, which can avoid leakage.

[0024] 3. The guide part can transport the liquid medicine into the liquid cup along the inner wall of the liquid cup, playing the role of buffering the liquid flow rate. BRIEF DESCRIPTION OF THE DRAWINGS
