Abstract
A low position gravity transfusion device relating to a medical apparatus, in particular relates to a dripping transfusion device. It comprises a transfusion can(1), code weight(6), a liquor bag(7),a transfusion nozzle(14) and puncture outfits. Transfusion barrel is of cylindrical shape, the bottom of which is a circular arc with a through-hole in the center. The liquor bag is of soft round sphere shape, a transfusion nozzle(14), a gas-filled tube and a air filter are equipped on the bottom center. The puncture outfit being a transfusion device jointed with a sole hole structure. The code weight being set inside the transfusion can shapes in tally with the inside part of transfusion can. In the case of operating, the liquor filled liquor bag(7) is set inside the transfusion barrel(1), then transfuses the liquor into the body from transfusion nozzle(14) through transfusion device by the upper code weight(6) pressurization to the liquor bag(7). The invention is portable, has no pollution to the liquor and avoids the transfusion air embolism. It has a simple structure and cheap price.
Description
[technical field] the present invention relates to a kind of medical apparatus and instruments, particularly the gravity infusion set.
[technical background] intravenous drip is than intravenous injection/intramuscular injection, have the medicinal liquid input steadily, flow can regulate and control, more help advantages such as absorption of human body.So the technology of drip transfusion, in the clinical practice of contemporary whole world medical treatment by widespread usage.
Existing drip transfusion technology is that the container height with the splendid attire medicinal liquid hangs on the drip stand, and the air in the UNICOM external world relies on the gravity of medicinal liquid, and medicinal liquid is imported in the body.
Obviously, from drip transfusion, human body has been lived with regard in bond; Patient's activity will be subjected to strict restriction.And the overall process of drip transfusion needs therefore to cause a lot of difficulties to the patient than the long time.Particularly because there is the defective of poor stability in existing transfusion needle maintenance technology, careless slightly in long drip transfusion process, the seepage of will infusing accident causes unexpected injury to the patient.
Use existing drip transfusion technology, also need constantly in medicine bottle, to replenish air; The air that enters in the bottle at first will just can rise to the space of medicine bottle through " washing " of medicinal liquid.Obviously, when constantly inflating, medicinal liquid is also constantly polluted; Especially the gas that contains the virus evil is with in the medicinal liquid input body, and is bigger to the harm of human body.
The tube for transfusion that existing drip transfusion technology adopts is all long, is difficult to sneak into the interior gas emptying of pipe, carelessness is arranged slightly, the serious consequence of the aeroembolism of will infusing.
[summary of the invention] the objective of the invention is the defective at existing drip transfusion technology existence, and a kind of low bit gravity transfusion instrument is provided.It does not only need the container height of splendid attire medicinal liquid is hung on the drip stand, but also can arbitrarily move.
The object of the present invention is achieved like this: the splendid attire medicinal liquid, establish the spherical software medicinal fluid bag of a transfusion mouth in bottom centre, be placed on the bottom and establish in the cylindrical medicinal liquor barrel of a through hole, again shape and the inner repeated code that coincide of transfusion barrel are pressed on the medicinal fluid bag for circular arc, center.Do not establish gas tube and air filter, perforator is the transfusion device of single hole structure, is connected with medicinal fluid bag by the transfusion mouth that passes through hole.Repeated code compressing medicinal fluid bag is imported medicinal liquid in the body by transfusion mouth and transfusion device.
It is unrestricted that the present invention has a position of placing medical liquid container than existing drip transfusion technology, needs to replenish air in medical liquid container, can avoid liquid medicine contamination and transfusion aeroembolism and easy-to-operate, superiority significantly such as cheap.
The present invention is the update technology of existing drip transfusion device.
[description of drawings] concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing be the low bit gravity transfusion instrument that proposes according to the present invention partly cut open figure.
1. transfusion barrel among the figure, 2. at the bottom of the transfusion barrel, 3. observation port, 4. the transfusion bung, 5. transfusion barrel is carried band, 6. repeated code, 7. medicinal fluid bag, 8. snap ring, 9. dropping funnel, 10. infuse mouths, 15. perforators, 16. pilot holes, 17. bases of actuator, 11. tube for transfusions, 12. liquid medicine filters, 13. through holes, 14. on the arm.
Describe concrete structure and the working condition thereof of the low position gravity transfusion device that proposes according to the present invention in detail below in conjunction with accompanying drawing.
The present invention contains columniform transfusion barrel (1) and repeated code (6).
The bottom of transfusion barrel (1) is circular arc, and the heart is established a through hole (13) therein, and repeated code (6) is placed on transfusion barrel (1) In, the inside of its shape and transfusion barrel (1) coincide.
The present invention contains spherical software medicinal fluid bag (7).
This medicinal fluid bag (7) is placed on transfusion barrel (1) lining, place repeated code (6) below.Establish one in medicinal fluid bag (7) bottom centre and pass the transfusion mouth (14) that through hole (13) is connected with tube for transfusion (11).
The present invention contains the transfusion device that is connected with medicinal fluid bag (7) by transfusion mouth (14).
This transfusion device is not established gas tube and air filter, and perforator is the single hole structure.
In order to show the amount of liquid medicine of medicinal fluid bag (7) lining, establish end on observation hole (3) at transfusion barrel (1) sidewall.
For prevent tube for transfusion (11) and the transfusion mouth (14) disconnect and be easy to carry, at transfusion barrel (1) side-wall shaft to establishing snap ring (8).Dropping funnel (9) is fixed on the transfusion barrel (1).
Easy to operate in order to connect transfusion mouth (14) and tube for transfusion (11), establish two symmetric pilot holes (16) in transfusion barrel (1) bottom.
During work, earlier the medicinal fluid bag of splendid attire medicinal liquid (7) is put into transfusion barrel (1) lining, makes transfusion mouth (14) pass through hole (13).Both hands put in pilot hole (16), and perforator (15) is inserted transfusion mouth (14), utilize the dropping funnel of transfusion device (9) snap ring (8) to be fixed on the transfusion barrel (1) again, at last repeated code (6) are pressed on the medicinal fluid bag (7).Other is pressed the drip transfusion routine operation and gets final product.
[specific embodiment] implements preferred plan of the present invention: transfusion barrel (1) is for cylindrical, internal diameter φ=100 millimeter, high 250 millimeters [containing pilot hole (16) and base (17)], (2) are circular arc at the bottom of the transfusion barrel, the radius R of circular arc=80 millimeter, the weight of repeated code (6) is 1.5 kilograms, and its shape and transfusion barrel (1) are inner coincide.Medicinal fluid bag (7) is the software sphere, and capacity＞500 milliliter adopt high-intensity medical plastic cement to make.The internal diameter of transfusion mouth (14) and external diameter mate with perforator (15) and through hole (13) respectively.0.5 meter of transfusion device length overall is not established gas tube and air filter, and puncturing hole (15) is the single hole structure, and other is identical with existing transfusion device.
