Abstract
The utility model relates to a connector of an insulin abdominal cavity administration device, which is characterized by comprising a tube seat, a locking nut and a sealing sleeve, wherein the locking nut is connected to the exterior of one end of the tube seat through threads, and the sealing sleeve extending out of one end of the locking nut is arranged in an inner cavity of the tube seat in an interference fit way. The connector has the following advantages: when a patient uses the abdominal cavity administration device, a medicament injection port is connected with the locked silicone rubber sealing sleeve of the connector, thereby not only blocking a medicament inlet and preventing infection, but also enabling an injection needle head to inject a medicament conveniently; furthermore, the silicon rubber sealing sleeve can be replaced periodically. The connector is simple in structure and convenient to operate and use, and is sanitary, safe and reliable.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to a kind of insulin intraperitoneal administration device connector.
Background technology
Control of diabetes patient's blood sugar concentration generally adopts dual mode, the repeatedly subcutaneous injection of insulin of the first, promptly once a day or for several times carry out subcutaneous injection of insulin, during the subcutaneous injection administration, the peripheral blood circulation insulin concentration is higher than the result of liver insulin concentration, does not meet normal physiological condition.It two is to adopt oral drug therapy, though oral drugs can meet physiological condition from intestinal absorption, oral formulations can not be for a long time accurate blood sugar control effect.Continuous development along with the medical science technology, the therapy of intraperitoneal administration is approved gradually and is adopted, intraperitoneal administration can be absorbed very soon and enter patient's hepatic portal vein and enter liver, forms the Concentraton gradient that the liver insulin concentration is higher than peripheral circulation, more meets the normal physiological model of action.And can significantly reduce insulin dosage, and be difficult for taking place hypoglycemia, more above-mentioned dual mode improves sugar, the unusual better effects if of lipid metabolism.Intraperitoneal administration is meant and adopts insulin pump to place the patient external, administering mode at abdominal cavity heeling-in microtubular adopts high strength stability biocompatible materials to make the soft catheter of diameter in 0.5 millimeter, by the end importing patient body abdominal cavity of invasive methods with microtubular, the other end places external as the medicine injection port.At present, still there is not the special-purpose adapter that uses with insulin intraperitoneal administration matched with devices.
Summary of the invention
This utility model provides a kind of insulin intraperitoneal administration device connector that can use with the intraperitoneal administration matched with devices reasonable, easy for operation of constructing for solving the technical problem that exists in the known technology.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is: insulin intraperitoneal administration device connector, it is characterized in that: comprise base, locknut and sealing shroud, described base one end external screw-thread is connected with locknut, and the interference of base inner chamber is fitted with the sealing shroud that extends locknut one end.
This utility model can also adopt following technical scheme:
The tapered structure of described sealing shroud one end, the other end is a flat segments.
Be shaped on a through hole on the described sealing shroud axial direction.
The equipped end of described base inner chamber and sealing shroud is the conical cavity structure, and the base other end is shaped on female Luer.
Described sealing shroud adopts silastic material to make.
Described base and locknut all adopt hard PC plastic production.
Advantage and the good effect that the utlity model has are: because this utility model adopts technique scheme, when the patient uses the intraperitoneal administration device, the silicone rubber seal cover that the medicine injection port can be connected the locking of this connector belt, so not only can seal the medicine inlet protects from infection, also can be convenient to the injection needle injectable drug, the silicone rubber seal cover can regularly replace.This connector construction is simple, easy for operation, and safe and sanitary is reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, base; 1-1,, conical cavity; 2, locknut; 3, sealing shroud; 4, microtubular.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, insulin intraperitoneal administration device connector comprises base 1, locknut 2 and sealing shroud 3.Described base one end external screw-thread is connected with locknut 2, and the interference of base inner chamber is fitted with the sealing shroud 3 that extends locknut one end.The tapered structure of described sealing shroud 3 one ends, the other end is a flat segments.The equipped end of base inner chamber and sealing shroud is conical cavity 1-1, and the base other end is shaped on female Luer.Be shaped on a through hole that is used to be communicated with microtubular 4 on the described sealing shroud axial direction, the diameter of described through hole is 0.5mm.Described sealing shroud 3 adopts silastic material to make, and described base 1 and locknut 2 all adopt hard PC plastic production.
During use, microtubular 4 is inserted the sealing shroud intermediate throughholes from flat segments one end, with base and locknut locking, sealing shroud is promptly compacted, with being tightly connected of realization and microtubular then.
