Abstract
A soft body infusion pump comprises a silicone rubber liquid storage bag (2), a mandril (1), a bag protecting sleeve (3), an infusion tube (7), a flow control box (5) and an infusion end port (6), wherein, the liquid storage bag is of a circular tube shape and sleeved out of the mandril; the two ends of the liquid storage bag are fixed at the two sides of the mandril which is in the bag protecting sleeve; the center of the mandril has a medicine liquid passage; the lower end of the mandril is the outlet end of the medicine liquid; the head end of the infusion tube is connected with the outlet end of the mandril; the flow control box is arranged at the middle part of the infusion tube; the infusion end port is connected to the tail end of the infusion tube; the bag protecting sleeve (3) is an elliptical spherical soft body plastic sleeve, the upper and the lower ends of the bag protecting sleeve are respectively fixed with the upper and the lower ends of the mandril (1); the upper end of the mandril is provided with a liquid charging opening (4) in which a one-way valve is arranged. Because the bag protecting sleeve is a soft body plastic sleeve and is flat when the liquid storage bag is not charged with medicine liquid, the soft body infusion pump has very small volume, and relatively convenient storage and carrying.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments that trace continues transfusion, a kind of soft 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 all the box structure of hard, and volume is also bigger, deposits use and all need account for bigger space.
Summary of the invention
This utility model is intended to propose the structure of the less microinfusion pump of a kind of volume, a kind of soft infusion pump.
This soft infusion pump comprise silicone rubber reservoir, plug, protect capsule cover, tube for transfusion, flow-control box and fluid infusion port.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.Plug is in and protects in the capsule cover, and there is a medicine liquid channel at the center of plug, and the lower end of plug is the port of export of medicinal liquid.The top of tube for transfusion links to each other with the port of export of plug.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.Wherein protect the plastic sheath that the capsule cover is a spheric software of ellipse, its upper and lower end fixes with the upper and lower end of plug respectively.There is a filling opening upper end of plug, and a check valve is arranged in the filling opening.
This soft infusion pump is the plastic sheath of software owing to protect the capsule cover, and it is flat protecting the capsule cover when not filling medicinal liquid in reservoir, and volume is especially little, deposits and carry all more convenient.
Description of drawings
Accompanying drawing 1 is the structure chart of soft infusion pump;
Accompanying drawing 2 is a kind of outline drawing of flow-control box;
The specific embodiment
As shown in Figure 1, this soft infusion pump comprise silicone rubber reservoir 2, plug 1, protect capsule cover 3, tube for transfusion 7, flow-control box 5 and fluid infusion port 6.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 cover, and there is a medicine liquid channel at the center of plug, and the lower end of plug is the port of export of medicinal liquid.The top of tube for transfusion links to each other with the port of export of plug, and the flow-control box is positioned at the middle part of tube for transfusion, and fluid infusion port 6 is connected on the end of tube for transfusion 7.Protecting capsule cover 3 is the plastic sheath of a spheric software of ellipse, and its upper and lower end fixes with the upper and lower end of plug 1 respectively.There is a filling opening 4 upper end of plug, and a check valve is arranged in the filling opening.
When this soft infusion pump used, medicinal liquid can pass through the medicine liquid channel at filling opening 4, plug 1 center and a hole on this channel side wall is injected in the reservoir 2, and reservoir is expanded.The elasticity of reservoir makes medicinal liquid keep certain pressure.Open the flow-stopping clip 8 on the tube for transfusion 7, medicinal liquid can be imported in the patient body lentamente by passage, tube for transfusion 7, flow-control box 5, fluid infusion port 6 and the top transfusion needle thereof at plug center, reaches lasting, safe, administration suitably.
The structure of the flow-control box in this soft 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 restriction 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 is 0.5ml/ time * 4/h just.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.
