Description

atomizing cup

Technical field:

The utility model belongs to the technical field of medical devices, and relates to a medical drug atomization cup mainly used for disease prevention and respiratory system treatment.

Background technique:

At present, the treatment of acute and chronic pharyngitis, bronchitis, pneumonia, and dyspnea in medical clinics often uses atomized gas to introduce drugs into the affected area. Medical drug atomization cups are widely used in medical aerosol therapy. Devices, there are many kinds of medical drug atomizers in the prior art, and their general structure is generally a cup body, an upper cover and a spout sleeve. The upper cover; the bottom of the cup is connected to the oxygen tube, and the oxygen tube is connected to an external air source; the upper cover is connected to a T-shaped tube with a diameter of 15mmOD to introduce the atomized spray into the patient's end. The T-shaped tube may be connected to a mask or a mouthpiece to supply the spray to the patient. Patient; after the assembly is completed, turn on the gas source, and the gas supply volume is not less than 8L/min, and the spray can be formed; but the existing atomization cup has the disadvantage of low atomization rate, which makes the atomization effect unsatisfactory and cannot achieve better medical effect.

Invention content:

The purpose of the utility model is to overcome the above-mentioned shortcomings of the prior art, and provide an atomization cup with a simple structure and improved atomization rate.

In order to achieve the above object, the utility model adopts the following technical solutions:

The atomizing cup includes: a cup body, an upper cover and a spout sleeve; wherein, a second gas channel is arranged at the inner opening of the upper cover to increase the supplementary amount of external gas.

Furthermore, the second gas channel is an arc-shaped hole arranged on both sides of the inner opening of the upper cover, and a cover plate whose shape is adapted to the arc-shaped hole is fitted.

With the above technical solution, the utility model can achieve a higher atomization rate compared with other similar products in the market, because the design of the upper cover of the atomization cup adds a "second gas channel", that is, arc-shaped holes on both sides; Through the arc-shaped holes on both sides, the replenishment of external air can be increased, and the atomized medicinal liquid can be taken out of the atomizing cup more quickly and effectively, and supplied to patients. The second gas channel provides a stronger air flow to carry the atomized particles out of the atomizing cup. At the same time, the product design considers the simplification of the mold structure and cost savings during the mass production of the product, and the groundbreaking design of the cover structure can effectively meet the functional requirements of the second air inlet of the upper cover, and can also effectively reduce the difficulty of product molding. Reduce manufacturing costs.

detailed description:

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Referring to Fig. 1-Fig. 3 shows the embodiment of the present utility model.

The atomizing cup includes: a cup body 1, an upper cover 2 and a spout cover 3; wherein, the inner opening of the upper cover 2 is equipped with a second gas channel 1 to increase the supplementary amount of external gas.

In a specific embodiment, the second gas channel is an arc-shaped hole arranged on both sides of the inner opening of the upper cover, and a cover plate 4 whose shape is adapted to the arc-shaped hole is matched with the arc-shaped hole.

The cup body of the utility model: contains the medicinal liquid, and the cup body is engraved with a scale line, which can effectively indicate the volume of the poured medicinal liquid and meet the doctor's demand for quantitative liquid; the cup body is made of transparent medical grade PP material, which meets the requirements of medical equipment. Material safety requirements, the transparent cup body is also convenient for doctors and nurses to observe whether the cup is clean and free of dirt, and at the same time, they can observe the use of the liquid medicine; the oxygen tube interface under the cup body meets the requirements of the law for the oxygen tube interface, and is easy to access Air source; the cup body is designed to stand at the same height, so that when the oxygen tube is not connected, the cup body can stand stably, and it is not easy to dump or spill the liquid medicine; the inner and outer diameters of the stand are designed in consideration of the placement of the atomization cup of the ordinary atomization pump With the cooperation, the atomizing cup is fixed to the placement port firmly without gaps, and it is not easy to fall off from the atomizing pump.

Spout sleeve: By matching with the gap of the cup body, the condition of Bernoulli’s law is achieved; the diameter design of the small nozzle hole of the nozzle determines the spray volume; the inner design of the spout sleeve is designed with four sides interference design to ensure that the spout sleeve is combined on the cup body. The height will not be unstable due to the influence of the airflow pressure, thereby affecting the stability of the spray particle size; at the same time, the spout sleeve will not slip off the cup when the cup is turned upside down.

Upper cover: After tightening with the cup body, ensure that the liquid medicine will not pour out; the middle round hole can be connected with the T-shaped tube, and the spray can be introduced into the patient channel; the arc holes on both sides can introduce the outside air into the cup body, and accelerate the mist. The thawed spray rises into the patient channel.

Cover plate: After mating with the upper cover, the “fountain” ejected from the nozzle sleeve hits the cover plate to form a spray; after the cover plate is matched with the upper cover, the arc-shaped air inlets on both sides of the upper cover form a closed channel to ensure the arc The realization of the function of supplementing the external gas by the shaped air inlet.

Compared with other similar products in the market, the utility model can achieve a greater atomization rate, because the design of the upper cover of the atomization cup adds a "second gas channel", that is, the arc-shaped holes on both sides; The shaped hole increases the supplementary amount of external air, which can bring the atomized medicinal liquid out of the atomizing cup more quickly and effectively, and supply it to the patient. The second gas channel provides a stronger air flow to carry the atomized particles out of the atomizing cup. At the same time, the product design considers the simplification of the mold structure and cost savings during the mass production of the product, and the groundbreaking design of the cover structure can effectively meet the functional requirements of the second air inlet of the upper cover, and can also effectively reduce the difficulty of product molding. Reduce manufacturing costs.

The above description shows and describes the preferred embodiments of the present utility model. As mentioned above, it should be understood that the present utility model is not limited to the forms disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various Various other combinations, modifications and environments can be made within the scope of the utility model concept described herein, through the above teachings or the technology or knowledge in the related field.
