Description

Novel practical artificial negative pressure ball

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a novel practical artifical negative pressure spheroid.

Background

The successful and successful placement of the gastric tube is an important prerequisite for indwelling gastrointestinal decompression of the gastric tube or nasal feeding nutrition, and the following three methods are mainly used for generally judging the gastric tube in the stomach clinically:

1. the gastric juice is pumped back. After the stomach tube is inserted into the stomach, the sterile syringe is connected with the tail end of the stomach tube, and whether the stomach juice can be drawn out or not is checked by pumping back, 2, the tail end of the stomach tube is placed into a bowl filled with cold boiled water or normal saline, if bubbles escape, the stomach tube is mistakenly inserted into the trachea, and 3, the passing of water sound is checked. A sterile syringe is used to inject 10-20 ml of air into the stomach tube, and the stethoscope is placed on the upper abdomen of a patient and the patient hears the sound of the air passing through the water.

However, the air in the syringe is limited, and after the air is used up, the air needs to be sucked back and forth, and cold boiled water or physiological saline needs to be specially prepared by others in advance, so that the workload of nursing staff can be increased.

Patent No. CN203291370U discloses a controllable drainage negative pressure ball, is equipped with spherical elasticity drainage bag, and drainage bag top is equipped with drainage joint and gas vent, is equipped with the check valve on the drainage joint, is equipped with the blast pipe on the gas vent, is equipped with discharge valve on the blast pipe, and the tip is equipped with the leakage fluid dram under the drainage bag, is equipped with the fluid-discharge tube on the leakage fluid dram, is equipped with the leakage fluid valve on the fluid-discharge tube. When the drainage device is used, the drainage connector is connected with the drainage tube, and the drainage bag is manually pressed, so that gas in the drainage bag is discharged through the exhaust valve to conduct drainage. When the drainage liquid in the drainage bag is gradually increased and the negative pressure in the drainage bag is not in a better required negative pressure range, the exhaust valve is opened, the drainage bag is extruded to exhaust the air at the inner upper part of the drainage bag, the exhaust valve is closed, and the negative pressure in the drainage bag can be increased. However, the negative pressure ball cannot be used to determine whether the gastric tube is successfully inserted into the stomach.

SUMMERY OF THE UTILITY MODEL

The embodiment of the utility model provides a novel practical artifical negative pressure spheroid to when solving and judging whether the stomach tube inserts the stomach with the syringe, the air in the syringe is limited, then need come and go back to suction air after exhausting to and need other people to prepare cool boiled water or normal saline in advance specially before beginning, increase nursing staff's work load's problem.

The embodiment of the utility model provides an adopt following technical scheme: including stomach tube, joint mouth, press piston, valve, spheroid, gas outlet and gas outlet piston, the one end of stomach tube with the one end swing joint who links up the mouth, the other end setting that links up the mouth is in spheroidal inlet end, press the piston setting and be in on the joint mouth, the valve sets up in the spheroid, the gas outlet sets up spheroidal end of giving vent to anger, the gas outlet piston sets up on the gas outlet.

Furthermore, one end of the stomach tube is provided with a stomach tube cap.

Furthermore, the cooperation of the control pressing piston, the air outlet and the air outlet piston can control the air in the ball to enter and exit.

Furthermore, the valve is made of plastic film materials, is light in weight and can swing along with airflow.

Further, the ball body is made of transparent materials, and the valve inside can be observed.

Furthermore, the valve is arranged at one end close to the pressing piston, so that the sensitivity to airflow can be improved, and the swinging of the valve can be observed more conveniently.

Further, the valve is arranged in a direction perpendicular to the long axis of the sphere. So as to increase the impact area of the airflow and improve the disturbance effect.

Further, the number of the valves is multiple. The observation at different angles is ensured, and the judgment error is reduced.

The embodiment of the utility model provides an above-mentioned at least one technical scheme who adopts can reach following beneficial effect:

one is as follows: the utility model discloses practical artifical negative pressure spheroid under the prerequisite that does not have water, and whether the swing of usable spheroid valve goes to judge to insert by mistake in the trachea. Does not need other people to specially prepare cold boiled water or physiological saline, and can reduce the workload of nursing staff in clinic.

The second step is as follows: compared with an injector, the novel practical artificial negative pressure ball body has the advantages of more convenient use, more smooth operation and higher efficiency. When air is injected into the stomach tube, the air in the balloon is directly communicated with the outside air, so that the air can be injected into the stomach and is used inexhaustibly.

Thirdly, performing the first step; the utility model discloses whether artifical negative pressure spheroid of practicality is in the whole operation flow in judging the stomach, only needs a nursing staff to accomplish to can reduce the nursing staff power of lao.
