Abstract

Field syringe The syringe consists of: a) A bellows-shaped syringe body (9), with a thread (7) in the open part (8) and closed at the other end. b) A screw cap (3) that fits the thread (7) of the syringe. c) Inside the syringe, it has a needle (5) in the form of a staff, attached to the support (4) of the bottom of the cap (3), by heat welding. The syringe is prefilled in the laboratory for use, placed on a muscle mass and the medication is injected. It facilitates mass vaccinations and their use in chronic diseases (diabetes, etc.), even being the blind patient. It can be applied in veterinary medicine.

Description

Field syringe

Field of the Invention

This invention relates to the instrumental auxiliary medical doctor. It is useful in its use, such as syringes of easy handling and minimum size, for situations of Great emergency and in chronic treatments.

Background of the invention

As soon as an epidemic occurs, it mobilizes to doctors and health workers who have large syringes injecting with small doses person to person, with danger of infect such individuals with other infections.

Another possibility is to load the syringe disposable with the vaccine, either from laboratories or from the place of the epidemic.

There is also the possibility of carrying the vaccine or appropriate medicine in capsules attachable to syringes specific.

Another solution is to use vaccine injectors, with the disadvantage that these instruments, to work, They need a series of auxiliary machines.

Description of the invention

Our syringe only looks like standard syringes, in two things: one, which serves the same ends, and another, which also has a needle.

Our invention consists of a small syringe, which functions as a small bellows , of small diameter and small adjustable height, with an inner needle of small dimensions, which is attached to the closure cap thereof, and is previously filled in the laboratory with a specific vaccine or medication. Placing it on a muscle mass, such as the arms, thighs and buttocks, we press with the thumb or palm of the hand, and the inner needle of small dimensions, passes the membrane or base of it of a plastic-elastic material, which forms the main body of the bellows , allowing the needle, without any loss of medication, to penetrate the muscle mass of the body, as if pressing a thick coin on a fleshy part.

Said field syringe goes inside a cylindrical box that protects it from crushing and other incidents, allowing the maintenance of complete sterility until it is used.

The advantages of this invention in relation to prior art state consist of:

1.- Facilitate mass vaccinations, by ease of use of the syringe by anyone, with just press it on muscle mass. The syringe is previously filled in the laboratory.

2.- In case of chronic diseases, for example, diabetes, facilitates the use of it by the patient, even In the case of being this blind.

3.- The object of the invention is to have a syringe for use in circumstances where it lacks health personnel.

Description of the drawings

Figure one

Exterior view of two elements that form the campaign syringe of one part (1), the cylindrical cover of the upper part, and of another, the rings (2) characteristic of this campaign syringe .

Figure 2

We have the total exploded view of the field syringe : in the upper part (3) we have the lid, with a thread similar to the thread of the soft drinks, and in its lower part a support (4) where the needle (5) is held in shape of a staff, which facilitates the clamping of the same (5) and allows the medicine to circulate freely through it. The lid that closes the upper opening by means of a thread, (6) similar to the thread of the soft drinks, fits perfectly with the upper edge of the bellows, (7) plugging and closing the only inlet (8) of the bellows body (9 ).

Figure 3

In this sectioned figure of the field syringe we can see in the upper part the closure or cap fitted and the needle holder in the form of a rod; The elastic body of the bellows screwed with the cap is shown at the bottom, allowing a very large variation in the inner volume of the syringe. In the position of the figure its volume is the maximum.

Figure 4

In this figure we can see how the campaign syringe works, which discharges the medicine from inside it through the needle. Placed on the muscular mass and with the pressure of the palm of the hand (10), a movement takes place that moves the needle, crosses the inferior membrane and the muscular mass (11), flowing the medicine through the same.

Figure 5

This figure shows the external view of the field syringe , ready to be stored, previously filled in the pharmaceutical laboratory, available for use at any time.

Figure 6

This figure shows the view of the field syringe after being used.

Figure 7

It presents the view of the cylindrical box that serves as a container for the campaign syringe , at its maximum volume. It protects it from crushing and other incidents, also allowing the maintenance of complete sterility until it is used.

Manufacturing method

This bellows-shaped syringe will be approximately the size of a large thimble , with a capacity of 2 to 5 ml. It can be manufactured with two dies or molds, one of them for the production of caps, and the other for the body in the form of the bellows of the syringe. The needle would be made in the form of a staff.
