Description

Pediatric Retention Enema

technical field

The utility model relates to the technical field of medical appliances, in particular to a children's retention enema device with accurate medication and not easy to block.

Background technique

Retention enema is an operation method that injects medicines from the anus into the intestines and makes them stay in the intestines to achieve the purpose of treatment. It is mostly used for medicine in children. At present, the pediatric enema used clinically is packaged separately from the syringe barrel and the extension tube, and the extension tube needs to be manually installed on the syringe barrel when in use, which delays the medication time in emergencies. In addition, the patient is too young to cooperate well, which makes it difficult to grasp the depth of the extension tube inserted into the anus of the child. The amount of liquid medicine for pediatric medicine is relatively small, and part of the medicine is often left in the extension tube during administration, which affects the accuracy of medicine. The clinically used pediatric enema also has the situation that the extension tube is easy to block, which affects the medication.

SUMMARY OF THE INVENTION

The purpose of the utility model is to provide a kind of children's retention enema that does not block and completes medication, aiming at the inconvenience of the existing children's enema.

The utility model is accomplished in the following manner: a pediatric retention enema device comprises an enema syringe, an extension tube and an air intake assembly, the extension tube is connected with the enema syringe, and the extension tube is inserted into the baby In the anus, the extension tube is provided with a scale, which is convenient for medical staff to measure the insertion length of the extension tube when operating, and the medicinal liquid in the enema syringe is injected into the body of the child through the extension tube; To the air valve 1, the trachea is set in the piston of the enema syringe, one end of the trachea is provided with a one-way air valve, the trachea passes through the one-way air valve to one-way air in the cylinder of the enema syringe, and the other side of the trachea is unidirectional. One end extends out of the piston and is connected to the air bag, and the air bag can be squeezed to deliver gas into the enema syringe through the trachea to push the medicinal liquid remaining in the enema syringe, so that the medicinal liquid can be injected completely.

In the described pediatric retention enema, one end of the trachea penetrates the rubber stopper of the piston, the one-way air valve is set on the rubber stopper and is connected with the trachea, and the other end of the trachea passes through the piston rod of the piston, from the handle Extend to communicate with the air bag.

In the children's retention enema, the air bag is provided with a one-way air valve 2, the external air enters the air bag through the one-way air valve 2, and the air in the air bag flows into the trachea in one direction when squeezed, and no gas leakage occurs. It is safer and more reliable; after the medication is completed, the air pressure in the air bag is lower than the external air pressure, and the external air is supplemented into the air bag from the second one-way valve.

In the described children's retention enema, the end of the extension tube 2 is provided with a number of side holes, which can effectively prevent the part of the extension tube inserted into the anus from being blocked by foreign bodies and cause medication not to be smooth.

The air intake assembly in the utility model forms a one-way air passage in the enema syringe. After the piston is injected, the airbag is squeezed, so that the gas in the airbag enters the barrel of the enema syringe through the trachea and the one-way air valve. In the body, the air pressure is used to push the medicinal liquid remaining in the cylinder into the rectum or colon of children, which greatly improves the accuracy of medication. The one-way air valve at the end of the trachea prevents the gas in the barrel of the enema syringe from carrying the medicinal liquid back into the trachea, and the operation is safe and reliable. The second one-way air valve set on the airbag is used for supplementing the gas in the airbag, which is simple and convenient. The scale on the extension tube makes it easy to observe the depth of insertion during intubation operation. The enema syringe and the extension tube are connected together to reduce the time for installing the extension tube. For example, it has a significant effect when using sedatives for convulsive patients.

Compared with the existing retention enema, the utility model has the characteristics of complete and accurate medication and convenient operation.

Detailed ways

Below with reference to the accompanying drawings, the present utility model will be further described through embodiments.

Referring to Figures 1 to 2, a pediatric retention enema device includes an enema syringe 1, an extension tube 2 and an air intake assembly 3. The piston 1a of the enema syringe 1 includes a rubber stopper 1a1, a piston Rod 1a2 and handle 1a3, one end of the extension tube 2 is connected with the enema syringe 1, the medicinal liquid in the enema syringe 1 is injected into the body of the child through the extension tube 2, and the other end of the extension tube 2 is inserted into the anus of the child, There is a scale on one end of the extension tube 2 inserted into the anus, which is convenient for medical staff to measure the insertion length of the extension tube 2; the side wall of one end of the extension tube 2 inserted into the anus is provided with several side holes 2a, effectively preventing the extension tube 2 from being inserted into the anus part Medication is not smooth due to foreign body blockage;

The air intake assembly 3 includes a trachea 3a, an air bag 3b and a one-way air valve 3c. The trachea 3a is arranged in the piston 1a of the enema syringe 1.
