Disclosure of Invention :

A . Movement body which is the part no.(l)that comprises movement roller no. (2) presser no.(3) indicator no. (4) digital adjustment and illustration two valves no. (5) and no. (6) and duct for smoothing the indicator movement. Along with its duct sides are scaling numbers. In front of which are holes where digital adjustment and scaling values are fixed, where each side is different from the other. The presser is fitted with rubber piece to tighten pressing. The movement body (1) is twisted from the open end where the content body (8), of different sizes. Is contained and installed. B. Open-ended content body no, (8): consists of big and twisted outer hole where the movement body (1) shall be fixed, and small and twisted small hole where the injection needle no.(9)is installed during the injection process, or alternatively, the suction need (16)is installed during the filling process. The content body is made of the transparent whit glass and is scaled with number to indicate the quantity of insulin it contains. It is of different sizes. C Injection needle no.(9): twisted from inside on the end where the content shall be installed. In addition, it contains a rubber piece to control the liquid flow. Afterwards. The ripped off part is installed with the needle whose small end is protruded. The surface of the ripped off is twisted to correspond the twisting of the cover.

Economical insulin injection pen operating method:

A. Filling: the content body no. (8) is installed on the motor body no.(l), it is tightened and the filling tip no. (16) is installed on the content no. (8) then it is inserted in the insulin vial and we push an appropriate quantity of air into the insulin vial for which the insulin shall be taken for filling the content with the quantity required for injection for many days through rotating the movement roller to retreat the presser along with the insulin. Upon sucking the insulin, we would notice the movement indicator has gone back to the scale end. Thus, we replace the filling tip no. (16) with the needle no. (9). After installing the needle no. (9), we adjust the insulin present in the content in the content and push out the air produced from the filling process. Now, the pen is ready for many times injection.

B.Injection Method:

1-The patient will insert the needs and the roller (2)is moved to push the insulin. When moving the roller, the indicator no. (4) will move on the scale shown. Upon stopping on the number specified by the physician, the injection thus is done with the specified quantity.

Or

2- The patient will specify the quantity he would inject. So he would move the adjustment valve no. (6) to the specified number and fix it in front of the number. Afterwards, he will rotate the movement roller to push the presser.

When the indicator reaches ultimately the adjustment valve, the injection is so done.

Or

3When injecting, the patient will remove the needle tap, or install it and place the pen on the injection place on the injection spot with fixing the cover on the skin by thumb and index finger while the pen is upright on the injection spot.

Afterward, the pen body is rotated twice so that the needle tip can by inserted into the injection spot without feeling pain, and he will rotate the movement roller to press the insulin specified quantity(use of adjustment valve is preferred) and the pen is rotated in a direction opposite to the former rotations so that the injection needle may be taken out without feeling pain. Economical insulin injection pen use method with the other containers(pen vials):

- We place the insulin vial (designed for other types of pens)in the alternative content no.(10),then install and tighten the content on the movement body no. ( 1 ). Afterwards, we install and tighten the needled on the alternative content and move the movement roller (2)for pressing and producing one or two drops for adjustment, and so the pen will be ready for injecting.

The alternative content body is made of the transparent whit glass and is of different sizes. ( in the case of mconsistence of the inner tip of the motor body ( 1 )and the outer tip of the

alternative content body (10), we may use the joint no.(l 1) or (12) which is open-ended for the movement of the presser between the two compartments, and is tipped from two sides, one inner and another outer, for the sake of correspondence of and linking the two parts. It is of different sizes.

Brief Description of Drawings:

Fig. 1 : (9 Injection needle :

-It is divided (apparently) into parts: one round and twisted from inside to be installed on the screwed part of the content body. And has a small round rubber piece inside which is fixed at the end of screw at the round bottom, and the beginning of the injection needles that goes first through the rubber piece.

The second part of the injection needle is screwed from outside in such a way sufficient for moving the injection needle tap on it when rotating the pen during injection so that the needle can go in and out the patient body without feeling pain.

(as the former.

(15Body of economical insulin injection pen: after assembling its three parts

(motor body - content body - injection body).

(16 Filling tips: filling tips are installed on the content body when suction and filling in the economical insulin injection pen. Fig. 2:

(1 Movement body (motor):

Where all the pressing and suction processes occur during injection and suction. It has a duct for moving the director easily. In addition, the duct ends have scaled numbers in front of which are holes for fixing the adjustment valves therein. It contain the also the movement roller tightened on it to prevent any slip. It is screwed in the open end for the presser going out. This screwing from inside is for matching with the outer screwing of the content body or the alternative content body to be installed. All parts of movement body can be made of excellent plastic, aluminum or any such a good and appropriate metal.

(2 Movement roller):

Is fixed tightly on the movement body using supporters before and behind it to prevent it from slipping. The presser goes through the movement roller, whose tips are matched with its ones to control the pressing movement during injection and suction movement during filling. It is made of be made of excellent plastic, aluminum or any such a good and appropriate metal.

(3 Presser (compressor):

It goes through the movement roller where its tips are matched with its ones. It is equipped with a rubber piece to control injecting insulin, and control suction during (filling). It is fitted at its end with a movement indicator which is screwed lengthwise. The presser be made of excellent plastic, aluminum or any such a good and appropriate metal.

(4 Indicator):

It is installed on the presser so that it can indicate, during presser movement and indicator moving between a number and another, the required number where the injection should stop. It moves forwardly in the duct during injection and backwardly during filling. It can be made of excellent plastic, aluminum or any such a good and appropriate metal.

(5 Back adjustment valve) :

It is installed on the movement body and is fixed manually in holes before each number to indicate the start-up of insulin quantity injected in the distance between it and the front adjustment valve.

(6 Front adjustment valve):

Is installed on the movement body. It is moved and fixed — before the number required for injection, the distance between it and the back adjustment valve is to identify the last quantity injected into the patient, it serves as a brake that prevent the indicator from moving forwardly unless it was moved manually to new number and holes. It can be made of excellent plastic, aluminum or any such a good and appropriate metal.

(7 Rubber piece):

It is installed on the presser to tighten the pressing or suction process , it can be made of excellent plastic. Aluminum or any such a good and appropriate metal on condition that it is reactive to insulin.

(13 Holes and numbers ):

Are numbers for indicating the concentration of the insulin used inside the pen, the appropriate scaling is used in case of using the insulin of 40 IU/ml concentration. The numbers are scaled and each number has a hole in front of which to install the adjustment valve thereon .

(14 Holes and numbers) :

Are numbers for indicating the concentration of the insulin used inside the pen. The appropriate scaling is used in case of using the insulin of 100 IU/ml, concentration. The numbers are scaled and each number has a hole in front of which to install the adjustment valve thereon.

(8 Content body) :

Is the reservoir of the insulin , its both ends are open. The great opening is screwed from outside so that it can be installed with the opening screwed from inside of the movement body. The presser goes through them to inject insulin or to fill. The presser starts from the movement body until the end of the content body lengths to push the last quantity of insulin and to such insulin when filling . the other opening is small and screwed from outside to install the injection needles or suction tip on it during filling . the content body has scaling to indicate the insulin quantity it contains. The quantity it can hold suffices the patient for many days. It has different sizes that vary according to the quantity it contains the content body is made of the excellent transparent white glass. (10 Alternative content body:

Its two ends are open . it is screwed from outside where it is installed with the motor body to allow presser to move from the motor by to push out the rubber piece of the imported insulin vial designed for the imported insulin injection pens. Installed inside the alternative content body, so that the insulin can be taken out of the injection needle installed on the small end of the content body into the patient body according to the physician subscription, it follows the scaling reading as in the case of injection using the economical insulin pen. The alternative content body is made of the excellent transparent white plastic, and it is of different sizes, as required, the two ends cannot be connected and we can use a joint instead.

(11 Joint):

A joint which is installed between the alternative content body and the motor body in case of inconsistence of the two scales, it is screwed in both sides and has two opening, one large and another small that allows for moving the presser easily between the two ends for pressing during injection, it is of different sizes.

(12 Joint) :

A joint used in the same way as the former, but it has different opening that will be installed with the motor body since all types of joints should be of two openings consistent with the motor body and the alternative content body (the joint is of different sizes)

(13 Sealing and holes):

Numbered scaling alongside the duct. This scaling is different from that opposite to it since the first is numbered according to the concentration of insulin of the content that will be injected to the patient. Thus, is one side is scaled showing that the insulin concentration is 40 iu/ml, the opposite scale should show that the concentration of the insulin used is 100 iu/ml, the physician will guide the patient and clarify this important point so that the patent may choose the appropriate scaling. The colors of two scaling are different, in addition, there are holes in front of the numbers (a hole against each number) to fix the adjustment valves in them.

14 Sealing and holes : functions the same

(17 Needle tap: the needle tap length is the same as the ripped off end s. it is screwed from inside. The tips of its screwing are matched with the tips of the ripped off end of the needle. The tap is fixed on the injection spot and is held thumb and index finger while the pen body is rotated by the other hahn twice so that the need tip is inserted into the injection spot painlessly.
