Technical field
This utility model relates to a kind of disposable use medical apparatus and instruments, the little dosage insulin of specifically a kind of disposable use continuous infusion device.
Background technology
We know, strict glycemic control can reduce and delay the various chronic complicating diseases of diabetes, and this fact is large-scalely clinically followed the disease medical experiment and confirmed by a plurality of both at home and abroad.The method of gradation injection is difficult to interior 24 hours insulin secretions of complete analogue body and reaches normal glycemic control, carry out the secretory function that the additional insulin pump of exogenous insulin then has pancreas under the simulation normal person physiological status with the pancreas form, can continue to export incessantly basal insulin in 24 hours, control fasting glucose relative normal range, thereby patient's blood glucose is well controlled.At present, domestic still do not have special-purpose and a matching used little dosage insulin continuous infusion device of insulin pump.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of structure reasonable, and operation, easy to use is with the little dosage insulin of the matching used disposable use of intelligent insulin infusion pump continuous infusion device.
The technical scheme in the invention for solving the above technical problem is: the little dosage insulin of a kind of disposable use continuous infusion device, it is provided with the insulin drawing out and infusion device of being made up of sleeve, push rod, piston, sealing member, back-up ring, it is characterized in that: described insulin drawing out and infusion device is connected with a connecting device, the insulin that needs infusion is pumped in the sleeve, the insulin drawing out and infusion device is connected with an infusion pipeline, carries out the insulin continuous infusion.
The said connecting device of this utility model comprises the double nip housing, and the housing middle part is hand-held frame, fixes one in the housing vertically and connects pin, and the two ends that connect pin lay respectively in the lower interface.During use, last interface is fastened on the back-up ring of insulin drawing out and infusion device, connect pin and pass sealing member, lower interface is connected with insulin reservoir, connect pin and pass cap of medicine bottle and soft plug, realize the connection circulation of insulin medicinal liquid,, just need the insulin of infusion to be pumped in the sleeve by pull push rod and piston.
The said infusion pipeline of this utility model comprises union joint, conduit, snap joint, entry needle.
This utility model adopts said structure, is connected with the infusion pipeline with connecting device respectively by the insulin drawing out and infusion device, and with the supporting use of intelligent insulin infusion pump, the continuous infusion of realization insulin.The contrast prior art, this utility model structure is reasonable, and operation, easy to use is the little dosage insulin of an a kind of ideal disposable use continuous infusion device.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is this utility model drawing out and infusion device and connecting device combinative structure sketch map.
Fig. 2 is this utility model drawing out and infusion device and infusion pipeline combinative structure sketch map.
1. push rods among the figure, 2. piston, 3. sleeve, 4. sealing member, 5. back-up ring 6. connects pin, 7. hand-held frame, 8. union joint, 9. conduit, 10. snap joint, 11. snap joints, 12. flaps, 13. entry needles, 14. entry needle helmets, 15. interfaces.
The specific embodiment
From Fig. 1, Fig. 2 as can be seen, the little dosage insulin of a kind of disposable use continuous infusion device, it is provided with the insulin drawing out and infusion device of being made up of sleeve 3, push rod 1, piston 2,4 of sealings, back-up ring 5, and concrete composition, the structure of drawing out and infusion device belongs to prior art, no longer describes in detail.
Insulin drawing out and infusion device described in the utility model is connected with a connecting device, will need the insulin of infusion to be pumped in the sleeve.As shown in Figure 1.Said connecting device comprises that with the housing of going up lower interface 15 the housing middle part is hand-held frame 7, fixes one in the housing vertically and connects pin 6, and the two ends that connect pin 6 lay respectively in the lower interface.During use, last interface is fastened on the back-up ring 5 of insulin drawing out and infusion device, connect pin 6 and pass sealing member 4, lower interface 15 is connected with insulin reservoir, connect pin 6 and pass cap of medicine bottle and soft plug, realize the connection circulation of insulin medicinal liquid,, just need the insulin of infusion to be pumped in the sleeve by pull push rod 1 and piston 2.Then, connecting device is removed from the insulin drawing out and infusion device, remove the outstanding counterclockwise back of changeing of the push rod of insulin drawing out and infusion device, so as thereafter with the supporting use of intelligent insulin infusion pump of special use.
Insulin drawing out and infusion device described in the utility model is connected with an infusion pipeline, carries out the insulin continuous infusion.As shown in Figure 2.Said infusion pipeline comprises union joint 8, conduit 9, snap joint 10, snap joint 11, entry needle 13.Also be provided with a puncture needle on the union joint 8.The quick disconnection that snap joint 10 and snap joint 11 can realize connecting duct 9 when needed be connected, and the sealing after guaranteeing to realize disconnecting, connect the function of back conducting, made things convenient for operator's safe handling.Entry needle 13 is intramuscular injection pins, can be draw point, also can be the muscle remaining needle, and entry needle 13 rear portions are provided with flap 12, and the outside is with entry needle helmet 14.Conduit 9 is that an internal diameter is Φ 0.1mm~Φ 1.0mm, and external diameter is the plastic catheter of Φ 1.2mm~Φ 2.5mm, and conduit can be made up of the polyolefine material and the outer field PVC material of internal layer, can be bilayer or multiple structure.During use, union joint 8 is connected with the back-up ring 5 of insulin drawing out and infusion device, puncture needle passes sealing member 4, sealing and bonding strength after union joint 8 can guarantee to connect.Air in a whole set of infusion pipeline of emptying then.(have liquid to ooze with entry needle 13, conduit 9 no bubbles are as the criterion.) site of puncture skin degerming on request, thrust entry needle 13 subcutaneous.On the skin of site of puncture, fix entry needle flap 12 with special adhesive tape.Then start special-purpose intelligent insulin infusion pump infusion apparatus, just can carry out the insulin continuous infusion, little dosage continuous infusion of the insulin of the pancreatic secretion of realization simulation human body.
This utility model is connected with the infusion pipeline with connecting device respectively by the insulin drawing out and infusion device, structure rationally, operation, easy to use, and with the supporting use of intelligent insulin infusion pump, realizing the continuous infusion of insulin, is the little dosage insulin of a kind of ideal disposable use continuous infusion device.
