Description

Pneumoperitoneum exhaust device

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to pneumoperitoneum exhaust apparatus.

Background

When a patient is punctured in the alimentary canal, gas enters the abdominal cavity through the punctured part to form pneumoperitoneum. At present, when pneumoperitoneum is treated clinically, a patient is in a lateral decubitus position, a piston of a common injector is pulled out, a needle head of the injector is inserted into the abdomen of the patient on one side far away from a bed surface, and then normal saline is added into a needle tube of the injector. If the puncture site is correct, it can be seen that the gas bubbles out of the saline in the needle cannula.

The current method has the following problems: the needle tube is rigidly connected with the needle head, and liquid in the needle tube can be poured out when the needle inserting angle is changed. If the liquid in the needle tube is not completely poured out, the needle inserting angle is limited, and the position and the angle of the exhaust needle cannot be flexibly adjusted.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the deficiencies of the prior art, providing a pneumoperitoneum exhaust device which can guarantee the needle tube to be upright under any puncture angle and the liquid in the needle tube can not be poured, so that the needle insertion angle is more flexible.

In order to achieve the purpose, the technical scheme is as follows:

a pneumoperitoneum exhaust device comprises a puncture needle, a hose, a liquid seal pipe and a buckle; the tail end of the puncture needle is provided with a pintle, and the pintle is connected with the hose through the pintle; the head end of the hose is provided with a hard connector which can be inserted into and connected with a pintle of the puncture needle, the tail end of the hose is provided with a pintle-like part which can be connected with the front end of the liquid seal pipe, and the puncture needle and the liquid seal pipe are connected through the hose, so that the puncture needle can be flexibly changed, and liquid cannot be poured out due to the inclination of the liquid seal pipe; the liquid seal tube is a barrel-shaped tube made of transparent materials, the front end of the liquid seal tube is provided with a hard tip part which can be connected with a similar pintle part at the tail end of the hose, physiological saline can be added into the liquid seal tube, and the liquid seal tube made of transparent materials is convenient for observing whether the physiological saline in the tube has bubbles to be discharged or not so as to judge whether the acupuncture position is proper or not; the buckle is arranged on the hose and used for controlling the smoothness and the closing of the hose, and is convenient for puncture operation and observation of bubble discharge.

As another preferred scheme of the utility model, the hose is the transparent plastic material, and length is 20 ~ 60cm to guarantee that the pjncture needle does not influence the stability of liquid seal pipe when carrying out the puncture operation.

As another preferred scheme of the utility model, the buckle is rectangle slice plastics, and the middle part is provided with the draw-in groove, the draw-in groove is transited gradually to the slit of opposite side by the circular hole in one side, circular hole diameter is greater than the type pintle portion diameter of hose, slit diameter is less than the hose diameter, and when the hose was in the circular hole position of buckle, hose channel opened, when the hose was in the slit position of buckle, the hose was extruded, and hose channel closes.

Compared with the prior art, the utility model provides a pair of pneumoperitoneum exhaust apparatus has following gain effect:

a pneumoperitoneum exhaust apparatus owing to increased the hose between pjncture needle and liquid seal pipe, can both guarantee under any puncture angle that the needle tubing is upright, liquid can not empty in it for the angle of inserting the needle is more nimble, has increased the carminative success rate of puncture.

Detailed Description

For a better understanding of the present invention, the following detailed description of the embodiments of the present invention is described in conjunction with the accompanying drawings.

As shown in the attached figure 1, the pneumoperitoneum exhaust device provided by the utility model comprises a puncture needle 1, a hose 2, a liquid seal pipe 3 and a buckle 4; the tail end of the puncture needle 1 is provided with a pintle 11, and is connected with the hose 2 through the pintle 11; the hose 2 is made of transparent plastic material, the length is 40cm, the head end is provided with a hard connector 21, the hard connector can be inserted into and connected with the pintle 11 of the puncture needle 1, and the tail end is provided with a pintle-like part 22 which can be connected with the front end of the liquid seal pipe 3; the liquid sealing tube 3 is a barrel-shaped tube made of transparent materials, the front end of the liquid sealing tube is provided with a hard tip part 31 which can be connected with the similar pintle part 22 at the tail end of the hose 2, and the inside of the liquid sealing tube 3 can be added with physiological saline; buckle 4 is rectangle slice plastics, and the middle part is provided with the draw-in groove, the draw-in groove is transited gradually to the slit of opposite side by the circular hole of one side, and circular hole diameter is greater than hose 2's class pintle portion 22 diameter, and the slit diameter is less than hose 2 diameter, and buckle 4 installs on hose 2 for control hose 2 unobstructed and close.

When the puncture needle is used, the puncture needle 1, the hose 2 and the liquid seal pipe 3 are connected into a whole, the slit position on the buckle 4 is placed on the hose 2, at the moment, the hose 2 is clamped, and liquid and gas in the hose 2 cannot pass through. Taking a patient in a lying position, taking a proper puncture site and a proper needle inserting direction, inserting the puncture needle 1 into the patient, erecting the liquid seal pipe 3, placing normal saline in the liquid seal pipe 3, transferring the hose 2 from the slit position of the buckle 4 to the position of the circular hole, opening the channel of the hose 2, observing whether the normal saline in the liquid seal pipe 3 has gas to emerge or not, and if so, indicating that the puncture is successful; if no gas emerges, the puncture point or the needle inserting direction of the puncture needle 1 is adjusted, and the puncture is carried out again.
