Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an exploratory medication device for respiratory nursing. Background Art

[0002] The respiratory system includes the respiratory tract and lungs. In the treatment of respiratory diseases, it is necessary to apply medication to the patient's throat. At present, the treatment of respiratory diseases is generally by injection or oral medication, but these two methods cannot directly treat sore throats or tonsillitis, and the effect is not ideal. Sometimes it is necessary to deliver the medicine directly to the patient's affected area. At present, in the treatment of respiratory patients, there is always difficulty in administering medication. Common methods of administering medication include infusion or probing into the respiratory tract to administer medication.

[0003] Chinese patent document CN215780912U discloses a probe-type drug delivery device for respiratory care. The utility model discloses a probe-type drug delivery device for respiratory care, which belongs to the field of medical device technology, including a dispensing tube, a mixing tube and a drug delivery tube. The dispensing tube is marked with scales, the lower end of the dispensing tube is detachably connected to the mixing tube, the lower end of the mixing tube is detachably connected to the drug delivery tube, and a barrier sheet is arranged in the dispensing tube and the mixing tube. The three-section tube body of the utility model is detachably connected, so that the overall device is detachable and easy to clean, and the secondary use will not be affected by incomplete cleaning; the dispensing tube is marked with scales and provided with a sliding sheet, which can be used to control the amount of medicine, thereby increasing the accuracy of medication; the rubber tube is used to mix the medicine by manpower, thereby ensuring the mixing rate of the medicine, without consuming too much manpower, and being simple to operate; the air bag is changed into a medicine push rod, so that all the medicines are evenly used on the affected part through the sponge head as much as possible, thereby ensuring the utilization rate of the medicine and reducing the waste of medicine to a certain extent.

[0004] The prior art probe drug delivery device cannot mix the administered drugs in the drug delivery tube, and needs to prepare a mixing container separately, which is time-consuming, labor-intensive and inefficient. Most drugs entering the body are stored at a temperature of 2-8 degrees Celsius. The normal human body temperature is 36.5 degrees Celsius. For patients with surgical wounds, using low-temperature drugs will cause great pain and be unbearable. Utility Model Content

[0026] Among them, a temperature regulating cavity 16, a vibration plate 26 and a scale line 21 are provided on the periphery of the dosing tube 11. The temperature regulating cavity 16, the vibration plate 26 and the scale line 21 are all arranged in the longitudinal direction of the dosing tube 11 and do not conflict with each other. The temperature regulating cavity 16 is integrally formed through the shell 13. According to the size of the temperature regulating cavity 16, two or more groups of temperature regulating cavities can be arranged on the circumferential surface. Each group of adjacent temperature regulating cavities 16 from top to bottom are connected by a connecting pipe 19. The two temperature regulating cavities 16 adjacent to the liquid outlet head 12 are connected by the connecting pipe 19. The two temperature regulating cavities 16 away from the liquid outlet head 12 are respectively provided with a cavity liquid inlet 17 and a cavity liquid outlet 18. The longitudinal temperature regulating cavity can be integrally formed or set to several, which are connected by the connecting pipe 19.
