Description

Push-rod type enemator for children

Technical Field

The application relates to the technical field of medical equipment, in particular to a push rod type enemator for children.

Background

Enema is a treatment of relaxing the bowels by inserting a catheter into the colon via the rectum from the anus to infuse liquid. It can stimulate enterokinesia, soften, remove feces, lower temperature, induce parturition, dilute intestinal poison, and supply medicine, nutrition, and water.

Enema is one of the common operations in pediatrics, an enemator is usually needed when children are clystered, but the clyster liquid flows out or excrement is sprayed out due to the tension of the children, so that inconvenience is brought to medical staff. In addition, most enemators used in the existing clinical treatment do not have the heating function, because the temperature difference between the enema and the body temperature of a patient is large, when the ice-cold enema is filled into the body of the patient, the body of the patient is easy to be discomforted, so that a series of stress reactions are caused, when the patient is cold, the patient feels more painful, and particularly, the stress reactions are stronger for children patients.

Currently, enemators with heating function are available on the market, but they have more or less some problems and drawbacks.

The overall working principle is as follows:

when in use, firstly, the enema is pumped into the inner cylinder of the syringe. The specific operation is as follows: when the structure is for the liquid medicine storage container of formula of uncapping, syringe inner tube, enema cannula, piston and push rod can act as traditional syringe and extract the liquid medicine in the container, and when the liquid medicine storage container who plugs up with the rubber buffer, then need unscrew the shower nozzle of enema cannula end and take off, compress tightly syringe needle and enema cannula connection, extract the liquid medicine again, after the liquid medicine extraction is accomplished, take off the syringe needle to revolve soon again with shower nozzle and enema cannula and close and be connected.

During the enema, insert the fixed degree of depth in patient's intestinal from patient's anus with the enema intubate to the protection casing that sets up on the enema intubate slides forward to patient's anus department, press the push rod at last will inject the enema in the inner tube and infuse the intestinal of patient in can, if the patient has enema or excrement and urine splash out when the enema, can direct splash to the safety guard on, and can not direct splash to medical staff on one's body, it has brought the convenience to carry out the enema to children for medical staff.

When in clystering, if the clystering liquid in the inner cylinder of the injector needs to be heated, the first cap is taken down from the first branch pipe, then a certain amount of cold water is poured into the outer cylinder of the injector through the first branch pipe, then the top wall of the second cap is pressed, because the top wall has elasticity and is easy to deform, under the action of external pressure, the top wall drives the sharp thorn part to move towards the direction of the air-tight film and finally puncture the air-tight film, at the moment, the granular heating agent stored in the accommodating cavity in the second cap falls into the outer cylinder of the injector along the second branch pipe and contacts with the water in the outer cylinder of the injector, after the heating agent contacts with the water, a large amount of heat is released immediately, and the heat can finally heat the clystering liquid in the inner cylinder of the injector through a heat transfer mode.

In this embodiment, the heat generating agent is calcium oxide that generates heat when it encounters water.

In this embodiment, the heating of enema need not can be realized through connecting external power source, compares not only application scope more extensive with the mode that adopts electric heating to the device is whole also safer, and manufacturing cost is also cheaper.
