Intelligent insulin attaching pump

Abstract

The invention discloses an intelligent insulin attaching pump. The intelligent insulin attaching pump comprises a shell, an insulin pumping device and a medicine box provided with a piston, wherein the insulin pumping device and the medicine box are packaged in an inner cavity of the shell, and the insulin pumping device comprises a power component and a transmission component which are connected in sequence; preferably, the power component comprises a micro motor and a gear reducer, and the transmission component comprises a transmission lead screw and a transmission nut; the rotating speed of the micro motor is reduced through the gear reducer, then the transmission lead screw is made to rotate at a low speed, motion is transmitted through the transmission nut so as to make the piston move along the inner wall of the medicine box to extrude and pump an insulin preparation out to be injected into the body of a patient through a subcutaneous remaining needle, the amount of residual liquid is small, hypoglycemia reaction possibly caused by the large length of a connecting pipeline in the prior art can be avoided, and waste of liquid medicine can be avoided so that expenses can be reduced. An output pipe tilting up by 45 degrees is arranged on the upper side of the outer end of the medicine box, an oblique hole inclining by 45 degrees is also formed in the corresponding position of the shell to allow the remaining needle to be inserted therein, and it is guaranteed that the remaining needle is inserted into subskin at 45 degrees too.

Description

technical field [0001] The invention relates to an intelligent insulin pump, in particular to a pump body structure of the intelligent insulin pump. Background technique [0002] In 1992, a kind of insulin pump was invented by Medtronic Corporation of the United States. This pump has a larger pump body, which is connected with the body by a long (about 35cm) infusion pipeline, and an indwelling The injection needle is buried under the skin of the abdomen, the injection dose and injection time are controlled by the button on the manual control pump body, and the basal dose of insulin is adjusted and controlled by the control software in the pump body. Compared with subcutaneous artificial insulin injection, this pump has the following advantages: 1. It can effectively control blood sugar, because there are hundreds of injections of water-dose basal insulin in addition to the daily pre-meal injection, which can effectively control blood sugar 24 hours a day. Control blood sug...

Problems solved by technology

But this pump has the following defects simultaneously: 1. It is extremely inconvenient for the patient to use. Because the pump body is relatively large, the patient generally hangs it on his shoulder or around his waist. It is inconvenient for the patient to exercise, take a bath, or sleep. The body has no waterproof function, let alone large-scale exercise and swimming and other sports; 2. It cannot protect the patient's privacy, and the patient must press the button on the pump body every time the peak insulin is injected before meals. Due to the large pump body, the temperature is high in summer and autumn When the pump body is exposed, the patient cannot protect the privacy of the patient; 3. The price is relatively expensive. At present, the price of imported insulin pumps is more than 40,000-60,000 yuan, and the monthly consumables are about 400-600 yuan, which increases the cost for patients. Burden; 4. Inability to effectively control hypoglycemia

Due to the long connection pipe, when the patient changes the medicine box at the end due to the high external pressure, the residual medicine liquid will enter the subcutaneous area at one time, causing excessive injection and causing hypoglycemia reaction; The pumping agent contains 200 units per milliliter, the tube needs to be changed 2 to 4 times a month, and about 20 to 40 units of insulin are wasted each time
