Description

Abdominal cavity deflation device

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to abdominal cavity degassing unit.

Background

With the development of the digestive endoscopy technology, the digestive endoscopy has the advantages of being minimally invasive, fast in recovery, low in cost and the like, so that more and more patients benefit from the digestive endoscopy technology. However, bleeding, perforation, infection and the like are common complications, particularly when a submucosal tumor is resected, perforation of the digestive tract is easily caused, so that gas in the digestive tract enters into the abdominal cavity, the intra-abdominal pressure is increased, and CO is generated₂The blood is diffused, the blood oxygen of the patient is reduced, serious patients have life risks, and the risk of the patient can be relieved and sufficient time is won for the operation by discharging the gas in the abdominal cavity.

At present, clinically, gas in abdominal cavity is removed, a 50ml syringe needle and a 20ml syringe are usually combined, about 5ml of normal saline is sucked, puncture is carried out at the position of a vertical clavicle midline under the rib edge of a patient, the sharpness of the 50ml syringe needle is utilized, pressure in the syringe can be seen after breakthrough feeling exists, a syringe piston is pulled out, a large amount of bubbles can be seen to emerge from the syringe, namely, the puncture is successful, and finally, the fixation is carried out, after the operation is finished, the wound surface is sutured, the abdomen is soft, and the syringe needle can be pulled out. However, the needle has a small diameter, so that the needle is easy to block the tube, and the needle is sharp and can be punctured for many times, so that the needle risks damaging viscera in the abdominal cavity.

SUMMERY OF THE UTILITY MODEL

Not enough and risk to prior art exists, the utility model provides an abdominal cavity air bleeder, the device have low cost, simple structure, easy and simple to handle and can reduce the risk to patient's intra-abdominal cavity internal organs damage, concrete technical scheme as follows:

the utility model provides an abdominal cavity bleeder, includes needle tubing 1, inner tube 2 and

standpipe

6, 1 bottom of needle tubing is syringe needle sharp end, 1 top of needle tubing is uncovered, and 1 top of needle tubing is outer along being equipped with two relative stationary vanes 4, standpipe 6 pipe diameter is greater than 2 pipe diameters of inner tube, 2 tops of inner tube and standpipe 6 bottom fixed connection, and be equipped with the check valve 5 of opening towards standpipe 6 directions in the junction, 2 bottoms of inner tube are blunt mellow and full open end, and a plurality of side openings 3 have been seted up to 2 bottom lateral walls of inner tube, inner tube 2 is the same with 1 length of needle tubing, just 1 cover of needle tubing is established outside inner tube 2 and can be outside inner tube 2 free sliding, makes needle tubing 1 and inner tube 2 relative emergence displacement.

The needle tube 1 is made of medical stainless steel materials.

The inner tube 2, the fixed wings 4 and the water storage tube 6 are made of medical hard plastic materials.

The working principle is as follows: pouring a small amount of normal saline or sterilized water into a water storage pipe 6 of an abdominal cavity air bleeder, wherein the water amount is half of the capacity of the water storage pipe 6, at the moment, a one-way valve 5 in the water storage pipe 6 is closed under the action of water pressure, a needle tube 1 and an inner tube 2 are relatively displaced by pushing out the needle tube 1, so that the sharp end of the needle tube 1 exceeds the blunt round opening end at the bottom end of the inner tube 2, then, the sharp end of the needle tube 1 is utilized to carry out abdominal cavity puncture operation at a proper position, after the sharp end of the needle tube 1 punctures the abdominal cavity and reaches the abdominal cavity, the high pressure in the abdominal cavity opens the one-way valve 5 towards the direction of the water storage pipe 6, a large amount of continuous bubbles can be seen in the water storage pipe 6, at the time, the inner tube 2 is pushed into the abdominal cavity at the puncture part until the bottom end of the water storage pipe 6 is abutted to the top, meanwhile, the side edges of the blunt round opening ends of the inner tubes 2 are provided with the side holes 3, so that the blockage of the needle head with a single pore passage caused by visceral organs or blood in the abdominal cavity can be avoided, and the smooth emission of gas is ensured. In addition, the fixed wings 4 can be fixed outside the abdominal wall to prevent the device from falling.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model provides an abdominal cavity air bleeder can avoid haring internal organs of abdominal cavity and blood vessel, reduces the puncture frequency, reduces stifled tub of rate, makes things convenient for medical personnel to operate, increases puncture efficiency, simple structure, low cost, the clinical popularization and use of being convenient for moreover.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

As shown in fig. 1 to 4, an abdominal cavity bleeder, includes needle tubing 1, inner tube 2 and

standpipe

6, 1 bottom of needle tubing is syringe needle sharp end, 1 top of needle tubing is uncovered, and 1 top outside of tubes edge of needle tubing is equipped with two relative

stationary vanes

4, 6 pipe diameters of standpipe are greater than 2 pipe diameters of inner tube, 2 tops of inner tube and 6 bottom fixed connection of standpipe, and be equipped with the check valve 5 of opening towards 6 directions of standpipe in the junction, 2 bottoms of inner tube are blunt nature mellow and smooth open ends, and a plurality of side openings 3 have been seted up to 2 bottom lateral walls of inner tube, 1 cover of needle tubing is established outside inner tube 2 and can be outside inner tube 2 free slip, makes needle tubing 1 and inner tube 2 relative emergence displacement.

Inner tube 2 is the same with 1 length of needle tubing, slide earlier needle tubing 1 during the use and make its syringe needle point sharp end surpass the blunt nature mellow and full open end of inner tube 2 bottom, utilize the syringe needle point sharp end of needle tubing 1 to pierce through behind the abdominal wall reacing abdominal cavity, impel inner tube 2 again and make 6 bottoms of standpipe support to 1 tops of needle tubing, its blunt nature mellow and full open end reachs the syringe needle point sharp end of needle tubing 1 simultaneously, make the partial blunt nature mellow and full open end of inner tube 2 expose in the abdominal cavity, this kind of structural design avoids the syringe needle point sharp end of needle tubing 1 to damage abdominal cavity internal organs, a plurality of side openings of the partial blunt nature mellow and full open end lateral wall that expose simultaneously can expose in exposing the abdominal cavity, avoid the jam that single syringe needle hole is leaded to by abdominal cavity internal organs.

The needle tube 1 is made of medical stainless steel materials.
