Abstract
A detachable type disposable infusion pump includes a feed liquid device and an infusion device. The feed liquid device comprises a silastic reservoir (3), a core rod (4) and a transparent reservoir protecting bottle (2). The infusion device comprises a perfusion tube (7), a flow control box (9) and a transfusion port (10). The feed liquid device is separated from the infusion device. The lower end of the reservoir protecting bottle is provided with a liquid inlet (5) which is provided with a screwed nipple, and the beginning end of the perfusion tube is provided with a connector (6). The feed liquid device and the infusion device are matched with each other by the screwed nipple arranged on the liquid inlet and the connector on the perfusion tube, so as to form an integrated disposable infusion pump. When in use, the capacity of the feed liquid device and the flow control performance of the infusion device can be conveniently selected and matched, thereby better adapting to the needs of different patients.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments that trace continues transfusion, a kind of split type disposable infusion pump of being used for.
Background technology
Microinfusion pump is a kind of apparatus that trace continues transfusion that is used for, and is mainly used in trace such as operation back pain relieving, chemotherapy and continues or interrupted administration.Existing microinfusion pump is an integral structure, and regulating power is relatively poor.
Summary of the invention
This utility model is intended to propose a kind of split type disposable infusion pump structure.
This split type disposable infusion pump comprises liquid feed device and infusion device.Wherein liquid feed device comprises reservoir, plug and the transparent capsule bottle that protects of silicone rubber.Reservoir is the pipe shape, tightly is enclosed within mandrel outer, and the two ends of reservoir are fixed on the two ends of plug with securing member.Plug is in and protects in the capsule bottle, and the lower end of plug fixes with the bottom of protecting the capsule bottle, and there is a medicine liquid channel at the center of plug.Infusion device comprises tube for transfusion, flow-control box and fluid infusion port.The flow-control box is positioned at the middle part of tube for transfusion, and fluid infusion port is connected on the end of tube for transfusion.Liquid feed device and infusion device are separated, there is a filling opening lower end of protecting the capsule bottle, and a check valve is arranged in the filling opening, and the outlet of check valve is connected with the medicine liquid channel at plug center, a nipple is arranged on the filling opening, and there is a union joint that matches with filling opening at the top of tube for transfusion.
Nipple on the liquid feed device of this split type disposable infusion pump and the infusion device dependence filling opening matches with the union joint on the tube for transfusion, is combined into a complete disposable infusion pump.Can select, arrange in pairs or groups the capacity of liquid feed device and the flow-control performance of infusion device easily when this structure is used, adapt to different patients' needs better.
Description of drawings
Accompanying drawing 2 is a kind of outline drawing of flow-control box;
Accompanying drawing 3 is the cut-away view of flow-control box shown in Figure 2.
The specific embodiment
As shown in Figure 1, this split type disposable infusion pump comprises liquid feed device and infusion device.Wherein liquid feed device comprises reservoir 3, plug 4 and the transparent capsule bottle 2 that protects of silicone rubber.Reservoir is the pipe shape, tightly is enclosed within mandrel outer, and the two ends of reservoir are fixed on the two ends of plug with securing member.Plug is in and protects in the capsule bottle, and the lower end of plug fixes with the bottom of protecting the capsule bottle, and there is a medicine liquid channel at the center of plug.Infusion device comprises tube for transfusion 7, flow-control box 9 and fluid infusion port 10.The flow-control box is positioned at the middle part of tube for transfusion, and fluid infusion port is connected on the end of tube for transfusion.Liquid feed device and infusion device are separated.There is a filling opening 5 lower end of protecting the capsule bottle, and a check valve is arranged in the filling opening, and the outlet of check valve is connected with the medicine liquid channel at plug center, and a nipple is arranged on the filling opening.There is a union joint that matches with filling opening 6 at the top of tube for transfusion.Union joint on the tube for transfusion 6 is spun on the nipple on the filling opening 5, and liquid feed device and infusion device promptly are combined into a complete disposable infusion pump.Can select the liquid feed device and the infusion device of different size to arrange in pairs or groups according to requirement during use, to adapt to patient's needs better to the amount of liquid medicine of the requirement of flow control performance and infusion.1 is hook among the figure.
When this split type disposable infusion pump used, medicinal liquid can pass through the medicine liquid channel at filling opening 5, plug 4 centers and a hole on this channel side wall is injected in the reservoir 3, and reservoir is expanded.The elasticity of reservoir makes medicinal liquid keep certain pressure.Medicinal liquid connects infusion device after adding well.Open the flow-stopping clip 8 on the tube for transfusion 7, medicinal liquid can be imported in the patient body lentamente by passage, filling opening 5, tube for transfusion 7, flow-control box 9, fluid infusion port 10 and the top transfusion needle thereof at plug center.
The structure of the flow-control box in this split type disposable infusion pump can be as shown in Figures 2 and 3.There is an automatic control to add medicine bag 14 and two current limiting tubes 15 in the flow-control box, wherein the two ends of a current limiting tube link to each other with back segment with the leading portion of tube for transfusion 7 respectively, leading portion and automatic control that another root current limiting tube is connected on tube for transfusion add between the import of medicine bag 14, and the outlet that automatic control adds medicine bag links to each other with the back segment of tube for transfusion by a gauge tap 16.11 are the pedestal of flow-control box among the figure, and 12 is button, and 13 is interim medicine-pouring port.Automatic control in this flow-control box add medicine bag be used for patient's pain unbearably the time the bigger dose of disposable injection come the analgesic.Automatic control adds the medicinal liquids in the medicine bag 14 because the control of current limiting tube needs just can be full of through the sufficiently long time, and for example 15 minutes, the volume of this medicine bag also was limited to a rational numerical, 0.5ml for example, and the maximum of automatic control dosing adds dose and just is 0.5ml/ time * 4/h.Patient pressed the button 12 o'clock, and automatic control adds medicine bag 14 and is squeezed, and gauge tap 16 is opened simultaneously, and the medicinal liquid that automatic control adds in the medicine bag 14 just injects in patient's body fast.When needs increased medicine in addition especially, the medical worker can inject medicinal liquids by interim medicine-pouring port 13.
