Detailed Description
The invention will be further explained with reference to the drawings:
as shown in fig. 1-7, a simple expired air condensate collector for a spontaneous breathing patient comprises a cooling bottle 1, a cylindrical cavity is arranged in the middle of the cooling bottle 1, a thermometer 4 is arranged on the side wall of the cylindrical cavity, a transparent observation port 7 is arranged on the cooling bottle 1 and used for observing the thermometer 4, and a collecting pipe 3 is embedded in the cylindrical cavity; the cooling liquid 2 is put into the cooling bottle 1, the front end of the collecting pipe 3 is in contact with the oral cavity, and the collecting pipe 3 is provided with an elliptical buccal mouth 5. The cooling bottle 1 is made of plastic, and particularly adopts a three-dimensional square structure. The collection tube 3 is cylindrical and has a volume of at least 400 ml. The transparent observation port 7 is a cavity partitioned from the cooling bottle 1, is not filled with the cooling liquid 2, and is convenient for observing the thermometer 4. The periphery of the cooling bottle 1 is wrapped with a thermal insulation sleeve 6. The structure of the heat insulation sleeve 6 is the same as that of the cooling bottle 1, and one side of the heat insulation sleeve 6 is provided with a notch 8. The cooling bottle 1 is placed on a shelf 9. The commodity shelf 9 comprises a base, wherein a 45-degree inclined plane 10 and a supporting surface 11 are arranged on the base; the collecting pipe is cylindrical with an upper opening and a lower opening, and a plug 12 is arranged at the lower opening.
The design principle is as follows:
the simple exhaled air condensate collector comprises a cooling bottle 1 sealed with cooling liquid 2, a cylindrical cavity is arranged in the middle of the cooling bottle 1, a condensate collecting pipe 3 can be embedded in the cooling bottle, the upper end of the collecting pipe is a mouth 5 of a patient, most of the middle part of the collecting pipe is arranged in the cooling bottle, air blown in from the mouth of the patient enters the collecting pipe and condenses into water drops when meeting condensation, and the water drops are gathered at the bottom of the collecting pipe; there is an arc thermometer in the place ahead that the cooling bottle contacted the collecting pipe, measures the temperature of collecting pipe, and the cooling bottle in thermometer the place ahead is transparent viewing aperture, and both sides seal and constitute the cavity, do not fill the coolant liquid in the cavity, conveniently read the temperature and observe sample collection volume. The insulating sleeve is arranged on the outer side of the cooling bottle, so that the palm of a patient is protected from being frostbitten, the insulating sleeve does not cover the front of the thermometer, and the thermometer number and the sample measurement are conveniently read.
The specific design mode is as follows:
the cooling bottle is a plastic product, the cooling liquid sealed in the cooling bottle can be common tap water, the cooling bottle is frozen in a refrigerator before use, the cooling bottle can be stored at room temperature at ordinary times, the cooling bottle can be repeatedly used, and the price is low; the cooling bottle is used for storing cooling liquid, a cylindrical cavity is formed in the middle of the cooling bottle, the cylindrical cavity is about 400ml, and a collecting pipe is placed in the cylindrical cavity. One side of the cylindrical cavity gap of the cooling bottle is provided with an arc thermometer. The cooling bottle in the direct place ahead of thermometer designs into transparent, and the cooling bottle of thermometer both sides cuts off, and the cooling liquid is not packed into in the transparent viewing aperture of cooling bottle in thermometer the place ahead, and convenient accurate reading thermometer is counted the digit.
The collecting pipe can be embedded into the cooling bottle, the volume of the collecting pipe is about 400ml (the volume of the exhaled air is large and small during quiet respiration), a large amount of exhaled air is prevented from flowing reversely during respiration, discomfort is avoided, and the oval mouth 5 is installed at the outer side of the cooling bottle at the upper end of the collecting pipe, so that the collecting pipe is convenient to suck. The part of collecting pipe embedding cooling bottle is cylindrical, and the collecting pipe bottom is sealed, and the bottom does not cover the clinical thermometer, conveniently observes the condensate liquid measure. In scientific experiments, a 1ml pipette tip can be jacked into the collecting pipe to suck condensate, and in clinical work, if the pipette tip is not used, a sample can be sucked out by using an injector. The collecting pipe is made of medical plastics, is disposable and low in cost, and can ensure sanitation and prevent cross infection.
Example 1: this simple and easy expiratory gas condensate collector can adopt hand-held type, but because the cooling bottle temperature is low, covers a lagging (shown in figure 4) around it when handheld, and the structure of lagging 6 is the same with 1 structure of cooling bottle, and breach 8 is seted up to one side of lagging 6, does not frostbite the palm when making things convenient for the patient to hold, and the collecting pipe below thermometer and the thermometer is not covered in lagging thermometer the place ahead, conveniently reads thermometer count and observes the condensate collection volume. The heat-insulating sleeve can be used repeatedly, and the cost is low.
Example 2: because the collection time reaches 5-10 minutes, it is tired to hold the cooling bottle and lead to the patient, the travelling comfort is poor, consequently this collector can also be with the help of auxiliary device, design a supporter promptly (shown in fig. 5 and 6), supporter 9 includes the base, be equipped with 45 inclined planes 10 and holding surface 11 on the base, the supporter is used for depositing devices such as cooling bottle when collecting the sample, keep cooling bottle and ground to form 45 left and right included angles, make things convenient for the patient to shelve it on the desktop and use, during the condensate is collected, can flow down along the collecting tube wall, improve agglutination efficiency. The storage rack for storing the cooling bottles is convenient to use, humanized, reusable and low in cost.
In the above embodiment, the patient exhales the gas to form condensate when the gas is cooled, the condensate is less accumulated at the bottom end of the collection tube, and the suction by inserting the pipette tip or the syringe is difficult, so that the specimen is sucked from the upper end of the collection tube, the inventors also think of the most preferable mode of the collection tube, and design a plug 12 (piston) at the bottom end of the collection tube as shown in fig. 7.
