Abstract

The utility model relates to a small-size steam sterilizing pot, which is composed of a pot body, a pot cover, and a safety valve, a steam release valve, and a pressure meter which are arranged on the pot cover, and a handle. The small-size steam sterilizing pot is characterized in that a pressure cooker with 24 to 28 centimeters is selected as the steam sterilizing pot body. A porous interlayer cover which can be fully closed and sealed is arranged on a sterilizing bucket, so the team sterilizing pot has the advantages of miniaturization, practicability and easy carrying. In addition, the utility model can prevent secondary infection and ensure sterilizing safety. Through hospital trial and bactericidal effect identification, the new product shows reliable sterilizing effect, high thermal efficiency, fast use and convenient carrying and is suitable for wide rural hospitals, and factory and mine medical health care.

Description

Small-size steam sterilizing pot

This utility model relates to the medical disinfecting utensil, particularly the small steam sterilizing pan of using about a kind of suitable vast rural area, factories and miness health care.

Existing medical vapor sterilization pot volume is big and heavy, only is applicable to cities and towns hospital.The medical health department of vast rural area and factories and miness dislike its heavy impracticable and few with so that need not, boil the replacement vapor sterilization with aluminum pot or aluminium lunch box with boiled water.This kind sterilization method does not often reach the requirement of sterilization.Be used to hold interior bucket uncovered when putting the sterilization of sterilization still into of sterilizing objects in addition, to be sterilized after, the bung that covers again without autoclave sterilization behind the bucket in taking out produces bacterial infection once more.Owing to medical apparatus sterilization not strict or the disinfectant utensil once more bacterial infection cause malpractice particularly serious in the rural area.The steam sterilization that CN20423355U proposes does not make improvements at above-mentioned defective, and therefore manufacturing and designing a kind of suitable vast rural area and the suitable miniaturization vapor sterilization pot of factories and miness medical health department is pressing for of medical and health industry.

The purpose of this utility model is can prevent sterile article bacterial infection once more for vast rural area and factories and miness medical health department provide a kind of, vapor sterilization pot that again can portable miniaturization.

The purpose of this utility model realizes with following technical proposals, this small steam sterilizing pan by pot body, pot cover and on relief valve, steam escape valve and Pressure gauge formed, it is characterized in that pot body is that pressure cooker and the corresponding high-pressure pot cover thereof of 240mm to 280mm formed by diameter; Place the interior disinfecting bucket of pressure cooker to have and make admission or airtight porous interlayer lid.

Embodiment of the present utility model as shown in Figure 1 and Figure 2.

Fig. 1 is the overall structure figure of small steam sterilizing pan.Wherein 1 is that steam escape valve, 2 is that high-pressure pot cover, 3 is that gland steam exhauster, 4 is that gland steam exhauster fixing head, 5 is that porous screen frame (unit), 6 is the tripod shelf, and 7 is that Pressure gauge, 8 is that relief valve, 9 is that disinfecting bucket, 10 is that pressure cooker body, 11 is that electrothermal tube, 12 is the interlayer lid.

Fig. 2 is the top view and the A-A cutaway view of the disinfecting bucket porous interlayer lid of small steam sterilizing pan, and wherein 13 is circular hole, and 14 is elliptical aperture, and 15 is the interlayer screw rod, and 16 for pulling turning handle.

Now this utility model construction features, duty and effect thereof are described with Fig. 1 and Fig. 2.

Selecting pressure cooker for use is that high pressure resistant vapor sterilization pot is to adapt to vast rural area and factories and miness unit's needs easy to use and carry, selects for use diameter 240mm to 280mm pressure cooker can reach the temperature and pressure requirement according to the specification requirement of sterilization and the principle of reasonable energy utilization.Cause the bacterial infection problem for solving in the utensil article exposure air of having sterilized, this utility model has designed porous interlayer sterilization bung (12) and has been made up of two layers of indent disk, every disk has some circular holes (13) and an elliptical aperture (14) apart from 3/4 place at its center, each center, hole to the angle between the line of circle disk center is 36 degree, disc centre is fixing with interlayer screw rod (15) up and down, the center in last lower disc hole is on same straight line, it is semicircle orifice that last disk has a hole, and upwards dig with its semicircle and to pull turning handle (16), last lower disc is that rotate at the center with the interlayer screw rod, pulls turning handle and make that the circular hole of lower disc is in corresponding communicating state on the interlayer when putting into autoclave up.Pull turning handle after sterilization finishes, make the atresia of lower disc on the interlayer partly all cover each hole of lower disc,, reach airtight and the purpose that prevents bacterial infection to prevent that covering outer air enters.

Thermal source of the present utility model can be the stove of outer heating, as coal stove, gas stove etc., also can be entered the electrical heating of the pressure cooker intermediary electrothermal tube in bottom (11) by the pressure cooker body sidewall.It is flat to tripod shelf face to add clear water before the heating in pot, and the disinfecting bucket of piling article is covered the porous interlayer lid, pulls porous layer and covers semicircular each circular hole that turning handle (16) makes upper and lower interlayer lid correspondence that communicates one by one of pulling.Steam discharge flexible pipe (3) is connected with steam escape valve (1) afterbody screws, and pass through from the slotted eye (13) of folder lid, fixing with disinfecting bucket sidewall fixing head (4) again.Put disinfecting bucket on the triangle shelf of pressure cooker, building high-pressure pot cover is available thermal source heating.This autoclave sterilizer operating pressure is 0.14 MPa, maximum temperature can reach 128 ℃ in the pot, and when vapour pressure in the pot during in 0.14～0.165 MPa, relief valve steam discharge voluntarily cuts out, pressure and temperature in the pot is remained in the prescribed limit, satisfy Ministry of Public Health and professional standard requirement.

This new product is reliable through hospital bactericidal effect assay certificate sterilization effect, and thermal efficiency height uses quick and conveniently, so reaches purpose of design of the present utility model.
