Description

Blood collector

This utility model relates to a kind of medical equipment, specifically, is exactly a kind of retracting device of adversary's intraoperative hemorrhage.

Intraoperative autologous blood transfusion is that infusion was given patient when the state of an illness needs after patient self was flowed out the anticoagulant of EV blood process, filtration or dilution, storage, and its advantage has: 1. avoid cross infection, prevent and treat blood transfusion infectious disease invasions such as acquired immune deficiency syndrome (AIDS), hepatitis; 2. there is not immunoreation to the allosome blood component; 3. save the blood source; 4. solve rare blood type such as Rh (-) sexually transmitted disease (STD) people's blood supply problem; 5. patient can be defeated by immediately after reclaiming, blood group need be do not checked; 6. expanding blood volume is timely and effective, improve erythrocyte oxygen and effect soon, temperature is suitable, cuts down expenses, reduce even avoid using storehouse blood or the like, and at present, collect way commonly used from body blood and be to use " blood recovery machine ", be exactly after filtration, Red Blood Cells Suspension (generation slurry blood) are fed back and give patient after the washing with blood, although it is respond well, but cost an arm and a leg, have only seldom the hospital of counting to have, and have only economic condition preferably patient just have an opportunity to use.And in the considerable hospital of China, do not having under the situation of above-mentioned condition, surgical personnel usually reclaims blood with simple and crude method, as in the storage blood bottle that uses common sterilization suction catheter to collect to provide for oneself, through 8 layers of filtered through gauze (every 500ml change once filter gauze) to infusion bottle, be defeated by patient then again, in addition with the sterilization medicine glass ladle out, syringe such as takes out at open collection way greatly, these ways all have shortcomings such as easy pollution, efficient is low, the feedback amount is little, do not meet the blood transfusion requirement.

This utility model aims to provide a kind of aseptic, nontoxic, no thermal source, can be used in ectopic pregnancy, liver and spleen rapture, the thoracic cavity trunk massive hemorrhage patient autohemic " non-washing type " anticoagulant when performing the operation, filtration, recovery such as break, and directly infusion is given patient's device.

Solution of the present utility model is: main part is a hard storage blood bottle (10), and has set up into blood suction catheter (2), attracts head (1), vacuum suction pipe (7), closing cover (14), anticoagulant bag (15) and organize isolation cover (18).On storage blood bottle, be provided with into blood mouth (3), filtering mesh bag (9), decoagulant-adding port (4), vacuum aspiration port (6), hook (5) and easy-to-pull blood infusion mouth (12).Suction catheter (2) and suction catheter (7) in use respectively with go into blood mouth (3) and link to each other with vacuum aspiration port (6).Anticoagulant bag (15) is an optional accessory, and the bottle top of storage blood bottle (10) can be column type or oblate column type, and the bottom is a funnel-form, connects the blood infusion mouth (12) of lower end; The available medical grade rubber of blood infusion mouth (12) seals, but and peripheral hardware plastics easy-to-pull type bung flange, after making it to drag can with the blood transfusion syringe needle directly plug blood transfusion; Bottle can have the containing mark sign that increases progressively on the wall from bottom to top, but the upper bottle wall can be thickeied, and nick, is provided with hook (5); Suction catheter (2) can be the silica gel tube or the plastic tube of inner wall smooth; " cecum " of coupled attraction head (1) established the aperture of 3～5 millimeters of several diameters, attracts head for preventing that tissues such as omentum majus from stopping up, and designed in this programme and organized isolation cover (18), can cover in during use to attract outside the head (1); Going into blood mouth (3) caliber can closely be connected with suction catheter (2), and the lower end is goed deep in the filtering mesh bag (9); Decoagulant-adding port (4) diameter can be complementary with the anticoagulant outlet tube and be connected; Suction catheter (7) diameter can closely be connected with vacuum aspiration port (6); Suction catheter (2) also can closely be connected with suction catheter (7); Go into blood mouth (3), decoagulant-adding port (4) and vacuum aspiration port (6) and can be connected in the form of bottle cap (8) on the storage blood bottle, also can be directly fixed on the storage blood bottle; This covering device can use transparent medical plastic or silica gel to make; The pore size filter of filtering mesh bag (9) is 40um, and its shape is like the bag shape of a upper end open, and the bag mouth periphery is fixed on the one side at storage blood bottle top, has in the net into blood mouth (3) deeply; The mesh bag bottom can be blunt round, and the cork cot line parallel also is close in the storage blood bottle on the side bottle wall, make the mesh bag filtering blood after, blood can slowly flow down along a bottle inwall; Consider the custom or the actual needs of some hospitals, be provided with decoagulant-adding port (4) and anticoagulant bag (15), adjusting control valve (16) is arranged on the outlet tube of anticoagulant bag (17), enter the dose and the speed of storing in the blood bottle in order to adjusting.

Because this utility model has adopted above solution, so can collect blood to greatest extent, and can make the blood of collecting be in air-tight state all the time, aseptic, nontoxic, no thermal source; Slowly flow down because of blood filters tailing edge bottle inwall through mesh bag, can alleviate erythrocytic destructiveness; When continuing to collect blood, also can carry out autohemic feedback; And since easy and simple to handle, theatre sister's workload can be alleviated greatly.

The utility model is described in further detail below in conjunction with drawings and Examples

Fig. 1 is a user mode profile of the present utility model, and Fig. 2 is the schematic perspective view at reflection this utility model top, and Fig. 3 is an adnexa of the present utility model.Wherein: 1. attract head; 2. advance the blood suction catheter; 3. blood inlet; 4. decoagulant-adding port; 5. link up with; 6. vacuum aspiration port; 7. vacuum suction pipe; 8. bottle cap; 9. filtering mesh bag; 10. store the blood bottle; 11. blood; 12. blood infusion mouth; 13. capacity sign; 14. closing cover; 15. anticoagulant bag; 16. control valve; 17. anticoagulant outlet tube; 18. organize isolation cover.

During use, open the package by the sterile working, to attract head (1) and suction catheter (2) to be put in operating-table is connected and is fixed in correct position, and (2) be connected on the blood mouth (3), storage blood bottle (10) by hook (5) hang on the other correct position of operating-table a little less than the operating field height (with the railing of the drip stand of reduction or treatment center all can), suction catheter (7) is connected to vacuum aspiration port (6) locates, and connect vacuum extractor, the adjusting negative pressure is 0.1～0.2MPa; With peritoneal scissors one aperture, placement organizes isolation cover (18) to attract head to prevent that tissues such as omentum majus from stopping up, owing to form negative pressure in the storage blood bottle, blood is just wild after (1) → (2) → (3) enter filtering mesh bag (9) inner filtration from patient's art, slowly flow down along the bottle wall, be stored in the storage blood bottle.Usually the body cavity internal hemorrhage often is not blood coagulation, so can be anti-condensation when collecting, but as when running into special circumstances and need use anticoagulant, anticoagulant infusion orifice (17) is cut off with sterile scissors, being connected to decoagulant-adding port (4) locates, hang up anticoagulant bag (15), adjusting control valve (16) makes it enter by 1: 4 amount with blood and stores in the blood bottle; After collecting full one bottle, separate (2) and (3) and (6) and (7), change a new bottle again; After collection finishes, remove (17), behind separation (2) and (3), (6) and (7), (2) are connected with (7), operation can continue to use suction pump; (3), (4), (6) are put closing cover respectively, (5) are hung on the drip stand, after the wild no contraindication of exploratory operation, drag the plastics bung flange of the liquid infusion orifice (12) of dehematizing, plug the blood exchange transfusion set autoblood is fed back to patient.
