The utility model has the structural characteristics that a compressed-air cylinder 13 is communicated with the containing cup 3 via an air valve 9, a pressure reducing/regulating valve 10, an air outlet valve 11, an air outlet pipe 12; the containing cup 3 and the containing cup cover 5 are hermetically connected via a clamp 4; after a physic liquor bag 7 is held into the containing cup 3, a small conic surface on the perfusion pipe of the physic liquor bag 7 is matched with the conic hole below the containing cup to make the inner cavity of the containing cup become an airtight cavity; adjusting the pressure reducing/regulating valve 10 can change the infusion speed.

Description

Pressurizing infusion set

Pressurizing infusion set belongs to medical instruments field, and it is to have set up pressurization and pressure controlling device on the basis of common transfusion tool, is equipped with special appearance cup, medicinal fluid bag, reaches aseptic, safe, effect easily.Be applicable to transferring from one hospital to another in patient's clinical emergency treatment, the infusion process, check, situation such as operation.

Existing transfusion way is that infusion bottle is hung on the drip stand, and the input of medicinal liquid is to lean on the formed pressure of difference in height of liquid bottle and human body that medicinal liquid is pressed into human body.When need are transferred from one hospital to another critical patient when infusing, or transfusion frontier inspection in critical patient limit looked into or shock patients is needed situations such as patient's transfusion in transfusion fast and the operation, existing transfusion tool was obviously both required great effort, and inconvenience, and its medicinal liquid again communicates with outside air and can not realize that strictness is aseptic.

By above analysis, this utility model is proposed, its purpose is: overcome the inconvenience pressurization that existing infusion techn exists, must may wait defective with there being antibacterial to invade in drip stand and the infusion process, and a kind of pressurizing infusion set is proposed, provide effective infusion set for needing the patient of transfusion in transferring from one hospital to another, check, performing the operation.

Technology implementation scheme of the present utility model is: tank of compressed air and adnexa, appearance cup, stilligout etc. are loaded on the same mounting.The gas outlet of tank of compressed air communicates with appearance cup inner chamber through air valve, decompression pressure regulator valve, air outlet valve, escape pipe; Holding cup is a garden post, garden awl assembly, and lid is established on top, and a little taper hole is established in the lower end; Near system one little taper face medicinal fluid bag and its tube for transfusion connecting part, the medicinal fluid bag Rong Beihou that packs into, the bellmouth of tapering part on the medicinal fluid bag tube for transfusion and appearance cup bottom closely cooperates, and after covering the appearance bowl cover and using clamp fastening, an appearance cup inner chamber is an airtight cavity.During transfusion, mix up out atmospheric pressure on request, loosen air valve, air outlet valve, Compressed Gas just charges into and holds in the cup, and the compression medicinal fluid bag is realized pressure transfusion.

Therefore, it possesses following advantage: without support, do not need the medicinal liquid bottle to be higher than human body when a) infusing, can arbitrarily be placed on suitable place; B) servo-actuated is good, and unit opinion is portable or hang on the stretcher, and what all do not influence the patient transports and be with fluid inspection, hands art; C) pressurization is convenient, pressurization to indivedual patients is infused fast, only need stir the knob of pressure regulator valve can realize: d) safe in utilization, be equipped with airtight medicinal fluid bag, prevented that medicinal liquid from dripping off bleeding from anus liquid and blowing back into tube for transfusion, or the air admission human body, the medicinal liquid of also having eliminated existing transfusion tool communicates with outside air and is not strict aseptic shortcoming.

This utility model has embodiment and accompanying drawing as follows.

Among the figure: 1. stilligout; 2. dropper deck; 3. hold cup; 4. clamp; 5. appearance bowl cover; 6. cassette tape; 7. medicinal fluid bag; 8. crosspointer Pressure gauge; 9. air valve; 10. decompression pressure regulator valve; 11. air outlet valve; 12. escape pipe; 13. tank of compressed air; 14. appearance saucer; 15. steel cylinder seat; 16. syringe needle; 17. adjustment valve; 18. tube for transfusion; 19. mounting.

Details are as follows to present embodiment in conjunction with the accompanying drawings:

Tank of compressed air 13 after the inflation in the steel cylinder seat 15 of packing into, inserts decompression pressure regulator valve 10 on the joint of the side of air valve 9; The outlet that two tracheas of crosspointer air gauge 8 connect outlet side (also can pick out the port of export of air valve 11) the decompression pressure regulator valve 10 of air valve 9 and decompression pressure regulator valve 10 respectively picks out air valve 11, and air outlet valve 11 links to each other with escape pipe 12; Escape pipe 12 charges into post-decompression gas and holds cup 3 inner chambers, holds cup 3 and puts into appearance saucer 14, and fix with cassette tape 6.

During use medicinal fluid bag 7 packed into and hold in the cup 3, and the fine taper face on its drain pipe is adjacent to the bellmouth that holds cup 3 bottoms, make with clamp 4 then and hold cup 3 and hold bowl cover 5 and tighten airtight.The head end of one-time infusion tube 18 is connected on the tube for transfusion of medicinal fluid bag 7, and it is stand-by that end does not install infusion needle 16.Stilligout 1 is pressed into to be convenient in the dropper deck 2 observe.Hold cup 3, tank of compressed air 13, stilligout 1 all fixes on mounting 19.For ease of observing the residual liquid quantity in the medicinal fluid bag 7, hold cup 3 and can make, or make with metal with transparent material, hold vertically fluting of cup, and be bumped into several slidies.

Volume is 500 milliliters a tank of compressed air 8 as calculated, charges into 8 atmospheric gases, just can be for the liquid of 40～50 bottles of inputs.Can inflate again after using up.

Clinically, at first mix up decompression pressure regulator valve 10, close air outlet valve 11, medicinal fluid bag 7 is packed into hold in the cup 3 on request, connect tube for transfusion 18 and open air outlet valve 11 again, operation transfusion routinely to needed pressure.Transfusion speed is cooperated by air outlet valve 11, adjustment valve 17, decompression pressure regulator valve 10 to be adjusted.Close gas check valve 9 after transfusion finishes, pull up syringe needle 16 and get final product.

This utility model is practical, but reuse indefinite duration.
