Description

Ball type air-proof leather strip

Technical Field

The utility model relates to the field of medical equipment, in particular to spheroid formula air proof leather strap.

Background

Under the present circumstances, due to the serious shortage of medical staff, one doctor needs to manage more than ten patients, so that all the patient conditions cannot be noticed at any moment during transfusion, and the risks of transfusion ending, liquid in a leather strip being emptied and gas entering blood vessels later occur. Clinical studies, with more than 50ml of gas entering the blood vessel, there is a risk of pulmonary embolism leading to death of the patient. Particularly for rescuing patients with massive hemorrhage shock, in order to rapidly expand the volume of liquid blood in blood vessels, the blood bags and the liquid bags are pressurized to rapidly replenish liquid, and residual gas in the infusion bags can be greatly extruded into the blood vessels after the infusion is finished without worry, thereby causing serious life risks to the patients.

Before the invention, the existing transfusion leather strip can not avoid the problem that gas enters blood vessels, and needs to be timely treated by workers or nursing families, but medical staff is in shortage and the nursing families are not professional, so that the condition that gas is brought into human bodies after transfusion is finished in different degrees is often caused, and huge potential safety hazards are brought to patients.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the defects and developing a spherical air-proof leather strip.

The technical scheme of the utility model:

the utility model provides a spheroid formula air proof leather strap, sets up accuse fast valve on the long pipe and the end continues to be the interface, its main technical characteristics are, and plastics needle passes through pipe connection upper bag chamber, puts a clean shot in the upper bag intracavity, and this clean shot is located upper bag chamber lower extreme opening, goes up bag chamber intercommunication lower bag chamber, and lower bag chamber communicates long pipe.

The hollow ball is positioned on the opening at the lower end of the upper sac cavity.

And a circle of rubber pad is arranged at the bottom opening of the upper sac cavity and corresponds to the hollow ball.

And a water filling port is arranged at the left upper part of the lower sac cavity and is sealed by rubber.

The middle part of the long catheter is provided with a speed control valve, and the upper end of the long catheter is connected with the bottom of the lower sac cavity.

The utility model has the advantages of and the effect lie in that last cyst cavity bottom opening part is provided with the round rubber pad, and swing joint clean shot on the rubber pad, clean shot have buoyancy in aqueous, and when liquid was full of long pipe, lower cyst cavity, was gone up the cyst cavity, the clean shot floated, can continuously loop through last cyst cavity, lower cyst cavity, long pipe entering human from the leading-in infusion liquid of plastics needle. When the infusion of the liquid in the infusion bag is finished, the hollow ball is closely attached to the rubber pad, so that the liquid in the lower bag cavity is prevented from continuously entering the human body, and the gas in the infusion bag is prevented from continuously entering the human body through the leather strip. The utility model discloses simple structure, safe and reliable, application scope are wide, and very big make things convenient for doctor's operation treatment, effectively avoid the huge risk that gaseous input blood vessel brought when the infusion finishes.

Drawings

FIG. 1 is a schematic view of the structure principle of the present invention.

In the drawings, each reference numeral indicates a corresponding component name as follows:

the device comprises a plastic needle 1, an upper bag cavity 2, a hollow ball 3, a rubber pad 4, a water filling port 5, a lower bag cavity 6, a long conduit 7, a speed control valve 8 and a connector 9.

Detailed Description

The invention is further described with reference to the following specific drawings and examples.

As shown in fig. 1:

the utility model comprises a plastic needle 1, an upper capsule cavity 2, a hollow ball 3, a rubber pad 4, a water filling port 5, a lower capsule cavity 6, a long catheter 7, a speed control valve 8 and a connector 9.

Mainly comprises an upper sac cavity 2, a hollow ball 3 and a rubber pad 4 which are connected.

The structure is as follows:

the plastic needle 1 is positioned at the top and is hollow, the plastic needle is downwards connected with the upper sac cavity 2 through a catheter, the lower end of the upper sac cavity 2 is sequentially connected with the lower sac cavity 6 and a long catheter 7, the long catheter 7 is provided with a speed control valve 8, and the tail end of the long catheter is continued to be a connector 9; a circle of rubber pad 4 is arranged at the opening at the bottom of the upper sac cavity 2, and the hollow ball 3 is movably connected to the rubber pad 4; a water filling port 5 is arranged at the left upper part of the lower sac cavity 6, and the water filling port 5 is sealed by rubber; the middle part of the long catheter 7 is provided with a speed control valve 8, and the upper end of the long catheter 7 is connected with the bottom of the lower sac cavity 6.

The utility model discloses application process brief explanation:

in conventional transfusion, particularly in pressure blood transfusion and transfusion for patients with severe hemorrhage shock, the plastic needle 1 is connected with a transfusion bag (not shown and omitted in the figure), the ball body of the long catheter 8 is pushed downwards, the long catheter 7 is closed, the outer side wall of the lower sac cavity 6 is squeezed and then released, and the liquid part enters the upper sac cavity 2 and the lower sac cavity 6; at the moment, the needle cylinder is used for filling water into the lower capsule cavity 6 through the water filling port 5 and overflowing into the upper capsule cavity 2, so that the water level of the upper capsule cavity 2 is half full and the hollow ball 3 floats on the water surface; and opening the speed control valve 8, enabling the liquid or blood to sequentially pass through the plastic needle 1, the upper bag cavity 2, the lower bag cavity 6, the long catheter 7 and the interface 9, evacuating the gas in the leather strip, connecting the puncture needle and entering the blood vessel. When infusion is finished, the water level of the upper bag cavity 2 is gradually reduced along with the entering of gas in the infusion bag along the plastic needle 1, the hollow ball 3 is reduced along with the reduction of the water level, once the water in the upper bag cavity 2 is completely flowed, the hollow ball 3 is attached and connected with the rubber pad 4, so that the air in the upper bag cavity 2 cannot pass through, particularly, during pressurized infusion, the gas pressure is tightly pressed, the hollow ball 3 is attached to the rubber pad 4 in a sealed mode, the gas is tightly blocked in the upper bag cavity 2, and the gas is effectively prevented from entering a human body. The water filling port 5 is elastically sealed by rubber, the needle can puncture the rubber to add medicine or liquid, and the needle can be pulled out to be sealed again. The speed control valve 8 is used for closing the long catheter 7 or regulating the infusion speed; the interface 9 is used for connecting a human body blood vessel puncture needle (not shown and omitted in the figure). The operation process is simple and convenient, medical staff are greatly liberated, and various hazards caused by gas entering human bodies are avoided. The utility model discloses can unify the standard, low in production cost, simple structure is compact, and the principle is clear and definite, has liberated medical staff, can clearly and definitely effectual be used for clinical infusion to implement, especially shock patient's pressurization infusion treatment.
