Abstract
The utility model relates to a heart type pressed blood-transfusing machine and belongs to a blood-transfusing tool. The blood-transfusing speed of a blood-transfusing machine composed of a blood bag, a whether pipe, a regulating machine and a needle head can not meet the need of an extremely serious patient. The utility model increases a pressed blood-transfusing pump copying the function of a heart on the present blood-transfusing machine. The pressed blood-transfusing pump is composed of a storing pressed machine, a one-way valve, etc. The blood-transfusing speed can reach to 100 ml/min. The utility model has the advantages of safe operation and no pollution. The utility model not only can be used to transfuse the blood but also can be used to transfuse the liquid.
Description
This utility model relates to a kind of core type pressurization blood exchange transfusion set, belongs to the blood transfusion instrument of clinical use.
The blood transfusion instrument of hospital clinical use at present is to lean on the gravity of blood itself to make blood inject intravital blood exchange transfusion set through tube for transfusion, and its transfusion speed is 200ml/h.In order to accelerate transfusion speed, often use inflating bag clinically, bigeminy ball pressurization transfusion bottle and maneuver pressurization blood transfusion etc.These methods make transfusion speed bring up to 400ml/h, can satisfy general patient's needs, but to some major operation, the patient of traumatic hemorrhage or shock is then not ideal enough, in addition, bigeminy ball pressurization transfusion bottle has the danger of aeroembolism when blood transfusion, maneuver pressurization blood transfusion makes medical worker's physical demands big, and it is lasting to be difficult to.
The purpose of this utility model is to provide a kind of transfusion speed fast, simple in structure, easy to operate, safe and reliable core type pressurization blood exchange transfusion set.
This utility model is achieved in that it is the pressurization blood transfusion apparatus that has increased the imitation cardiac function on the existing blood exchange transfusion set who is made up of transfusion needle, tube for transfusion, Murphy dropper, demodulator and intravenous needle.Described pressurization blood transfusion apparatus comprises and holds liquid prelum and two check valves.Holding the liquid prelum is a container of being made by elastomeric material, at its import and export a check valve is housed respectively.The import of holding the liquid prelum links to each other with former blood exchange transfusion set's tube for transfusion, and its outlet links to each other with intravenous needle.Core type pressurization blood exchange transfusion set's operation principle is that the liquid prelum is held in extruding, and its internal pressure increases, and makes the valve closing of import department, and blood is in outlet valve injects human body.Stop extruding, hold the liquid prelum and restore, its internal pressure reduces, and outlet valve is closed, and imported valve is opened, and blood enters and holds the liquid prelum, moves in circles, and blood is constantly entered by the blood bag and holds the liquid prelum, enters in the human body by holding the liquid prelum again.As required, also pressurization blood transfusion apparatus that can two covers are above-mentioned is in parallel uses, and makes diplocardia formula pressurization blood exchange transfusion set.Pressurization blood transfusion apparatus in parallel is connected between former blood exchange transfusion set's the demodulator and intravenous needle, alternately blood is injected in the human body, accelerates the extruding frequency, improves transfusion speed.
The utility model has the advantages that transfusion speed is fast, can reach the 100ml/ branch; Visible component (as erythrocyte) destruction to blood is little, safe and reliable, no aeroembolism and germ contamination; Simple in structure, easy to operate, help production and popularization, use; Not only can be used for blood transfusion but also can be used for transfusion.
Fig. 1 is a holocentric formula pressurization blood exchange transfusion set structural representation of the present utility model, and among the figure: 1 blood transfusion needle, 2 tube for transfusions, 3 Mo Feishi pipe, 4 drainage screens, 5 demodulators, 6 tube for transfusions, 7 stay pipes, 8 check valves, 9 hold liquid prelum, 10 stay pipes, 11 check valves, 12 intravenous needles.
Fig. 2 is a diplocardia formula pressurization blood exchange transfusion set's of the present utility model pressurization blood transfusion apparatus structural representation.
Embodiment:
Referring to Fig. 1, holding liquid prelum 9 is elastic containers of being made by transparent plastic, and the import and export at its two ends is connected on respectively on the stay pipe 7 and 10 of duroplasts.Check valve 8 and 11 is that they are installed in the exit of stay pipe 7 and 10 respectively by opening of making of rubber and closed diaphragm, tube for transfusion 6 by stay pipe 7 with hold liquid prelum 9 and be communicated with.Intravenous needle 12 by stay pipe 10 with hold liquid prelum 9 and be communicated with.Holding liquid prelum 9, also can to make the organ qin box, and check valve 8 and 11 also can be made steel-ball type.
Claims (4)
1, a kind of core type pressurization blood exchange transfusion set, comprise transfusion needle 1, tube for transfusion 2, Mo Feishi pipe 3, drainage screen 4, demodulator 5, tube for transfusion 6 and intravenous needle 12, it is characterized in that being connected with the pressurization blood transfusion apparatus between tube for transfusion 6 and the intravenous needle 12, described pressurization blood transfusion apparatus comprises by what elastomeric material was made and holds liquid prelum 9, and the check valve 8 and 11 that is contained in the import and export end that holds liquid prelum 9 respectively, the entrance point that holds liquid prelum 9 is communicated with tube for transfusion 6, and its port of export links to each other with intravenous needle 12.
2, core type pressurization blood exchange transfusion set according to claim 1 is characterized in that described pressurization blood transfusion apparatus is two covers, is connected in parallel between tube for transfusion 6 and the intravenous needle 12.
3, core type pressurization blood exchange transfusion set according to claim 1 and 2 is characterized in that the described liquid prelum 9 that holds is organ qin box-type containers of being made by transparent plastic.
4, core type according to claim 1 and 2 pressurization blood exchange transfusion set, but it is characterized in that described check valve 8 and 11 is diaphragms of the opening and closing of being made by rubber.
