Abstract
The utility model relates to a sealing structure of a clean water tank of a gastric lavage machine, which comprises an upper tank body, a lower tank body and a rubber bowl. The rubber bowl coaxially installed between end surfaces of the upper tank body and the lower tank body divides the upper tank body and the lower tank body into a pressure cavity of the upper tank body and a liquid storage cavity of the lower tank body, an air nozzle is arranged on the upper tank body, the outer edge of the rubber bowl is formed into a cup-shaped sealing ring structure and embedded on the upper tank body or the lower tank body at a joint end surface of the upper tank body and the lower tank body. The sealing structure has simple overall structure, scientific and reasonable design, creative structure of sealing, liquid absorbing and discharge of the clean water tank, good seal effect, effectively avoids leakage of gases and liquid and guarantees normal operation of the gastric lavage machine.
Description
Technical field
This utility model belongs to medical instruments field, especially a kind of hermetically-sealed construction of paunch flusher clear water jar.
Background technology
Paunch flusher is the important machine of hospital's emergency rescue, and it is extracted out from gastric and carry out the displacement of gastric material by injecting clear water or medicinal liquid to gastric, through repeatedly repeating, reaches the purpose of removing the gastric noxious substance.Paunch flusher comprises formations such as clear water jar, sewage jar, various pipe valve and air driven pump, air driven pump provides malleation or negative pressure for clear water jar and sewage jar, with the turnover of compressing or contraction leather cup realization liquid storage intracavity liquid, this liquid enters the sewage jar by pipe valve or discharges outside the machine.At present, the clear water jar is the pressure-bearing jar, and pressure chamber and liquid storage cylinder carry out end face seal by the edge of leather cup, and leather cup adopts rubber to make, and its edge that seals is aging easily, and sealing effectiveness is relatively poor; And the pressure in the liquid storage cylinder is had relatively high expectations to the pipeline that connected and reversal valve, takes place easily to leak and pollutes accident; In addition, the check valve that the clear water in the existing liquid storage cylinder is installed by its underpart is realized the inspiration and the discharge of clear water, and the reliability of suction liquid is relatively poor, and structure is comparatively complicated.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the paunch flusher clear water jar hermetically-sealed construction of a kind of rational in infrastructure, design science, good sealing effect is provided.
The purpose of this utility model is achieved in that
A kind of hermetically-sealed construction of paunch flusher clear water jar, constitute by upper tank body, lower tank and leather cup, leather cup is coaxial to be installed between the end face of upper tank body and lower tank, and upper tank body and lower tank be isolated into the pressure chamber of upper tank body and the liquid storage cylinder of lower tank, be shaped on a valve on the upper tank body, wherein the outer rim of leather cup is made the cup seal ring structure, and be inlaid in upper tank body and lower tank joins and end face between upper tank body or lower tank on.
And, directly make or install a valve body at the lower bottom part of lower tank, interior the communicating with the liquid storage cylinder of lower tank of this valve body is shaped on a mixed flow chamber, and this mixed flow intracavity is communicated with an outlet and that links to each other with stomach tube respectively unidirectional diaphragm-operated water inlet is installed.
Advantage of the present utility model and good effect are:
1, the leather cup between the end face of upper tank body and lower tank, installed of this clear water jar, the cup seal ring is adopted in the sealing of its outer rim, and the cup seal ring is installed on the upper tank body or lower tank between the end face, has effectively improved sealing effectiveness, has avoided the leakage of gas.
2, valve body is made or installed to the lower bottom part one of the lower tank of this clear water jar, and the whole pressure-bearing effect of clear water jar is greatly improved, and also avoided the generation of leak of liquid accident.
3, this utility model overall structure is simple, and design science is reasonable, realized the structure innovation of clear water jar at sealing and suction liquid, and good sealing effect has effectively been avoided the leakage of gas, liquid, has ensured the normal operation of paunch flusher.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is the A portion enlarged diagram of Fig. 1.
The specific embodiment
Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.
A kind of hermetically-sealed construction of paunch flusher clear water jar is made of upper tank body 2, lower tank 5 and leather cup 4, is shaped on a valve 1 on the upper tank body, is used to connect source of the gas; Leather cup is coaxial to be installed between the end face of upper tank body and lower tank, and upper tank body and lower tank are isolated into the pressure chamber of upper tank body and the liquid storage cylinder of lower tank, when realizing that leather cup is installed, has also realized the coaxial end face seal installation of upper tank body and lower tank; The outer fringe seal structure of leather cup is made cup seal ring 3 structures, and be inlaid in upper tank body and lower tank joins and end face between lower tank on (the present embodiment accompanying drawing is indicated on the lower tank, also can be installed on the upper tank body), improved the reliability of sealing, guaranteed the sealing of cavity.
For pressure-bearing and the sealing effectiveness that improves valve body, directly make a valve body 8 at the lower bottom part of lower tank, communicate with liquid storage cylinder in this valve body and be shaped on a mixed flow chamber 10, this mixed flow intracavity is communicated with an outlet 7 that links to each other with stomach tube respectively, and a water inlet 9 that unidirectional diaphragm 6 is installed.
Present embodiment is the mode that adopts valve body and lower tank integral production, also can make separate mode, but its pressure-bearing and sealing effectiveness are not as the structure of present embodiment.
Claims (2)
1, a kind of hermetically-sealed construction of paunch flusher clear water jar, constitute by upper tank body, lower tank and leather cup, leather cup is coaxial to be installed between the end face of upper tank body and lower tank, and upper tank body and lower tank be isolated into the pressure chamber of upper tank body and the liquid storage cylinder of lower tank, be shaped on a valve on the upper tank body, it is characterized in that: the outer rim of leather cup is made the cup seal ring structure, and be inlaid in upper tank body and lower tank joins and end face between upper tank body or lower tank on.
