WO2004080509A1 - Disposable cannula - Google Patents

Abstract

The inventive disposable cannula consists of a polymer tube (1) whose length ranges from 5 to 40 cm and diameter from 4 to 2 mm and which is pointed on one end thereof, thereby facilitating the introduction thereof into the subcutaneous fat of a patient. The opposite end of the tube monolithically takes the form of a nosepiece (3), which comprises an internal cone for the tight connection thereof to the spout (4) of a piston device like a medical siring (5). Said cannula is introduced into the patient body through a puncture in a fat area. The thus extracted fatty tissue divides into two fractions practically during a minute, thereby substantially reducing the time of operation. A fatty fraction is introduced into a predetermined area of the patient body or can be sent for preservation and subsequent use during half-year. The simple design structure and low cost production of said cannula prove the practicality of the single use thereof.

Description

 Cannula

The invention is related to medicine, in particular to medical instruments used to pick up or pump small-sized tissue into the human body.

The old level of technology

Devices for the removal of canvas from the human body are known. They are a type of medical device, such as a medical device. Such devices include a cannula, made in the form of a metal tube connected to a suction-discharge device and components. The devices of these are complex at their own expense, many are used due to the high cost and complexity of production. THERE ARE THE MORE DISADVANTAGES OF SUCH DEVICES. The convenience of using such devices significantly increases the risk of introducing an infection from another patient to a friend. Therefore, the creation of a cannula for a single application with a minimum capacity is very relevant.

Quick description of drawings

Β Further, the proposed invention is explained in the drawings, in the following:

Φig. 1 - Displays the cannula of the single access door and connects to the external device. Φig. 2 - removes a cannula from a short-hand working device connected to a portable device. BACKGROUND OF THE INVENTION

Ηa Φig. 1 cannula is shown, the working part 1 is made from an original material. Depending on the purpose, the working tube is 5 cm long to 40 cm long and 4 mm in diameter. up to 10 mm. The thickness of the pipe wall is 0.5 mm. up to 2 mm. One end 2 of the pipe is cut at an angle of 10 ° to 60 °. The abandonment of the tube is necessary to ensure easy access to the patient’s fatty tissue. The other end of the working case 1 has a multi-part connection to the nozzle 3, which has an internal case for a free access to a 4-way accessory

For use of the declared cannula, there may be a combination of a single “fence” and the subsequent introduction of a tissue from a single patient.

Intended use

From the operational description of the execution of the cannula, the usefulness of its use follows, and the operation associated with the neglect of human trafficking and the subsequent introduction of it. Obviously, also the usefulness of the possibility of accession of the acquired tissue.
