Description

Pushing rod for moving on IV poles, used for hanging up one or more drips or other medical appliances or apparatus

Technical field to which the invention relates

The moving on of IV poles for hanging up one or more drips or other medical appliances or apparatus

Description of the prior art

Drip bags and other medical help appliances are hung up on a IV pole

These IV poles exist of a vertical rod that is generally 2 meters high

The drip bags are generally hung up above or on eye height. This allows the drip liquid to drip into the body of the patient, due to gravity.

Medical appliances are also fixed to these IV poles, but then at a height that allows the caring person to read and / or operate the appliances when sitting or when standing.

The vertical rod usually exists of 2 rods sliding in each other, that can be fixed using a clamp or a screw.

Different drip bags are usually fitted with of different colours, which facilitates the connection to the distribution block and allows to see which tap needs to be opened or closed. The different connections of the distribution block have corresponding colours.

This vertical rod is mounted on a base. The base usually exists of several legs, that are parallel to the floor at a small distance, and which are placed in the shape of a star from a central point onwards.

The end of each leg then has a little wheel of a small diameter, that can rotate a full 360° an unlimited amount of times.

These IV poles are usually placed next to the bed of the patient, yet it also often happens that the patient may and can move freely through the hospital, while he needs to be connected to the drip or to the medical appliances. Then he will have to take the IV pole with him.

It is also possible to be moved through the hospital by the personnel or by a third person in a wheelchair or in a bed. Even then one is obliged to either transfer the drip or the medical appliances to a IV pole, that is fixed to the wheelchair or to the bed, or to move the IV pole with drip or medical appliance together with the bed or the wheelchair.

Disadvantages of the prior art

A lever function occurs by the fact that the patient takes hold of the IV pole, existing in only one rod, at a central place, namely at approximately one and a half wither height.

The lever function makes it extremely difficult to take on the slightest bump. It is a known phenomenon in the hospitals, that the patient pushes the rod with his foot, in order to go over a bump, or makes a rotating movement with his wrist.

Steering is very difficult, because the loose wheels do not always want to turn in the desired direction when the patient wants to take a certain direction. Here too, the patient or the nurse will tend to make a rotating movement with his wrist.

As a consequence of the rotating movement, the drip pipes are wound around the rod. You have to replace your wrist regularly and you keep on turning.

Taking short turns is difficult.

Because the feet are sticking out in the shape of a star in the direction of the patient, and are pretty long, the patient tends to trip over the legs.

Because the drip pipes hang loose, the patient tends to trip into the drip wires.

In the hospitals, there are currently a lot of accidents because the patient trips over the drip pipes or the legs. Certainly elder or weaker patients run the risk of falling and hurting themselves seriously. There are a lot of fractures. This is costing health insurance a lot of money and can even lead to the patient dying. Essential characteristics of the invention

A pushing rod 10/14 allows a IV pole 1 with legs mounted in star form with rotating wheels attached, to be pushed forward.

The pushing rod 10/14 is fixed as low as possible to the vertical help plate 3 or help rod or to the original IV pole 1.

The pushing rod 10/14 can be fitted with a handle 15, rotating around the length of the pushing rod 10/14.

The pushing rod 10/14 can hinge between the horizontal and vertical position. I.e., the pushing rod 10/14 can hinge on a surface that is going through the vertical IV pole 1 and is perpendicular on the base surface

The pushing rod 10/14 can hinge laterally to the left and right over 180°, i.e. the pushing rod 10/14 can rotate around a line that is coincides or runs parallel to the vertical IV pole 1.

Both hinging movements of the pushing rod 10/14 and the rotating movement of the handle 15 can be mutually combined.

The pushing rod 10/14 can be clicked up and fixed into a clamp 5, that is placed on a vertical plate 3 or rod, which runs parallel with the vertical IV pole 1 or directly to the original TV pole 1. The clamp 5 is proximally placed onto the vertical plate 3 or rod or on the original IV pole 1 .

Possibly an extra thickening piece 6 is fitted with between the vertical plate 3 or rod or original IV pole 1 and connection of the pushing rod 10/14, with such a thickness that the clamps 4 for the drip pipes and the drip pipes themselves are not cut off. Possibly an extra thickening piece is fitted with between the vertical plate 3 or rod or original IV pole 1 and the clamp 5 for fixing the pushing rod 10/14, with such a girth that the fixing is done without problems.

An identification can be stuck to the vertical plate 3 or rod as an indication of the top and bottom side. This for fixing the vertical plate 3 or rod to the vertically rising IV pole 1 in a correct way and for the correct fixation of the connecting piece 6 with the pushing rod 10/14.

An identification section 12 can be fitted with on the pushing rod 10/14, preferably close to the handle 15, to slide in patient identification.

The handle 15 or the whole or a part of the system can have a colour corresponding to a ward.

The vertical plate 3 or the vertical rod, fixed parallel to the original vertically rising IV pole tube 1, to which the drip or the medical appliance is fixed, is fixed in at least two places with an as large as possible space in between. This in order to receive the torsion force, executed when directing

The pushing rod 10/14 can also exist of two tubes sliding in each other, that can also be adjusted in length.

The pushing rod 10/14 can be dual, so that the length can be adapted to the arm length of the patient on the one hand, and on the other hand the leg length of the TV pole, and finally also to the position, sitting or standing, of the patient. The pushing rod 10/14 can have a fixed length, but be made in different lengths in function of the arm length of the patient, the leg length of the IV pole , the sitting or standing position of the patient.

The drip pipes are lead through the vertical plate 3 or rod, running parallel with the original IV pole 1, or original IV pole 1 across the pushing rod 10/14, to reach the patient, and fixed at regular distances with clamps.

Near the connecting piece 6, a free loop space is fitted in order to avoid the blocking of the drip pipes (so without clamps).

The clamps 4 are meant to guide the pipes, but not to fixate them. The clamps 4 for fixing the drip pipes, give free play to the drip pipes, so that they can move both ways

When the pushing rod 10/14 is dual, the tubes 10/14 are fitted with a signal 13 that indicates the maximum extraction.

Possibly, in case of duality, a stop is fixed, that prevents both tubes being taken apart 10/14.

The sliding in and out each other of the tubes 10/14 can only be done in a certain manner. The mutual turning of the tubes is made impossible, and the turning of the drip pipes is also made impossible

A chain 9 or other flexible connection or a pin 9b — slot 9a construction between the pushing rod 10/14 and the vertical plate 3 or rod or original IV pole 1 makes it impossible for the rod 10/14 to fall on the floor, the patient can immediately take hold of the rod 10/14 without having to stoop. Advantages of the invention

The lever functioning can be completely disabled when the pushing rod 10/14 is fixed as low as possible. This means as close as possible to the ground surface.

Regardless of the position of the patient, the connecting point is moved to a lower point.

Because the lever function has disappeared, it is a lot easier for the patient to take on bumps.

The patient does not need to put his foot against the base in order to take a bump.

The patient does not need to make a rotating movement with the wrist anymore.

The drip pipe cannot wind itself around the IV pole 1 anymore, because the patient does not need to make a rotating movement with his wrist in order to steer the IV pole tube embodiment 1.

The drip pipe is nicely lead to the patient with clamps 4 through the plate 3 or rod, parallel to the IV pole 1 and the pushing rod 10/14 , without any wrapping or entangling or loose pipes being possible

Besides, the freedom of movement of the pushing rod 10/14 is limited to a rotation of 180° to the left or to the right, around an axis that coinciding or runs parallel with the original drip IV pole 1. Concerning taking very sharp turns in a limited space : these can be taken very easily by rotating laterally, from left to right, possible in an almost vertical position of the pushing rod 10/14.

Because a chain 9 or other flexible connection or a pin 9b - slot 9a construction between the pushing rod 10/14 and the vertical plate 3 or rod or original IV pole 1 makes it impossible for the standard 10/14 to fall on the floor, the patient can immediately take hold of the pushing rod 10/14 without having to stoop

Because the body of the patient is at a sufficient distance from the IV pole 1 and its legs, the patient will not trip over the legs anymore.

Because the drip pipes are not hanging loose anymore, the patient will no longer trip and the drip pipes will no longer be damaged.

Because of all of this, there will be a lot less accidents with drip standards, patients will be spared fractures and health insurance will save heaps of money.

By simultaneously rotating the handle 15 the hand does not need to be replaced or turned when hinging the pushing rod 10/14. When hinging, there will also be a rotation around the longitudinal axis inside the pushing rod 10/14. This rotation inside the pushing rod 10/14 is compensated by the rotation inside the handle 15.

The pushing rod 10/14 will take little place and will not be disturbing when the IV pole 1 is not being pushed, because the pushing rod 10/14 can be pinned into the upper clamp 5 on the vertical plate 3. The drip pipes will not be cut off at the hinging points when the pushing rod 10/14 is in the upright position and the fixating of the pushing rod 10/14 in vertical position in the clamp 5 will not give any problems, thanks to the connecting pieces 5a/6 that are possibly between the vertical plate 3 or rod or original IV pole 1 and the pushing rod 10/14 on the one hand and between the vertical plate 3 or rod or original IV pole 1 and the clamp 5 for fixating the pushing rod 10/14 on the other hand.

Because of the fact that the upper and lower side of the vertical plate 3 or the rod, parallel to the original IV pole 1 are clearly indicated by the identification label, the fixating to the original IV pole 1, nor the fixation of the connecting piece 6 to the pushing rod 10/14 does not create any problem.

For the personnel, the identification space 12 with the patient identification is a supplemental advantage.

For the patient, the fact that the handle 15 or the whole or a part of the system has a colour corresponding to his ward, is a supplemental advantage.

The use of a vertical plate 3 or a vertical rod that run parallel to the original IV pole 1 and that are connected to the original IV pole 1 in at least two places with an as large as possible distance, will prevent that the pushing rod 10/14 comes loose because of the torsion force when executing a hinging movement.

Because the pushing rod 10/14 can be slid in and out, it can be perfectly adapted to the arm length of the patient, the leg length of the IV pole 1, the sitting or standing position of the patient. The fact that the tubes 10/14 cannot rotated against each other, avoids the twisting of the drip pipes.

A chain 9 or a pin 9b- slot 9a construction prevents that the pushing rod 10/14 is let down completely.

Optimal embodiment

The basis is an original IV pole 1 for drips in stainless steel with an outer tube diameter of 25 mm.

A small plate 3 with a length of 90 cm and a width of 3 cm in stainless steel will be used as surface running parallel with, and fixed onto the original standard tube

At 3 cm of the bottom end and on O cm of the top end and centrally, clamps 2 are fixed. So three in total. These clamps have 2 jaws connected by a bolt to each other. The screwing action fastens the 2 jaws and activates the clamping action. Each jaw consists out of an actual jaw section and a solid section. The first jaw is fixedly mounted on the plate 3 or rod. The second jaw has a protrusion on his surface, surface which touches the mirroring surface of the first jaw. The protrusion is situated on the distal section distal of the jaw section.

A main hole is drilled through the both solid sections, in this hole a bolt is fixed. The protrusion on the second jaw allows a stronger screwing action so that the fixation is also stronger. The main hole in the first jaw is elaborated in the following way. Perpendicular on the main hole a secondary hole is drilled with a diameter which is a few mm more than the diameter of the bolt which connects both jaws. In this secondary hole a metallic or non ferro plug is fitted. In this plug precisely at the intersection with the main hole a third hole is drilled. This third hole is fitted with a screwed tread. This screw thread is conceived to receive the connecting bolt. The head of the bolt is placed at the side near to plate 3 or rod and prevents the plug from falling out of the second hole. After mounting both jaws together by means of the bolt a nut is screwed and glued on the end of the bolt. Between the nut and the second jaw a round plastic plate is mounted. This in order to fasten the bolt durably and in order to protect the metal of the system from friction damage. The clamping action or the release of the clamping is obtained by turning the nut. This nut is placed distal to plate 3 or rod. Further the main hole in the first jaw is elaborated in the following way: the main hole is firstly enlarged in the surface where both jaws touch, in a direction perpendicular on plate 3 or rod. The main hole is secondarily enlarged in the surface near to plate 3 or rod distal of the touching zone also in a direction perpendicular on plate 3 or rod. The first enlargement has a width corresponding with the diameter of the bolt and a length of approximately twice that diameter. The second enlargement has a width corresponding with the diameter of the head of the bolt and a length of approximately twice that diameter. The first and the second enlargements allow the bolt and the plug to turn around the axis of the plug. The second enlargement allows also the screwing action and in that way the clamping action. In fact this second enlargement is also necessary to mount the bolt inside of the solid section of the first jaw. The second hole for the plug does not continue through the whole body of the solid section of the jaw, a few mm of metal are left. The secondary enlargement in the first hole is recovered after mounting the whole system. The clamp can not fall apart nor can be dismantled seen the final gluing of the nut at the end part of the bolt. So neither the patient nor the nurse can accidentally disassemble the system. The two enlargements in the main hole allow an additional flexibility in dismounting the system from the TV pole. The protrusion ameliorates the screwing and clamping action. In the actual situation the possibility of falling apart of the clamp is always possible due to a human error by nurse or patient. This of course is not desirable in a hospital environment. Using a clamp with two jaws which are clamping by means of a screwing action and which have touching surfaces without a protrusion will result in a limited clamping force so that eventual the clamp will rotate around the tube. As alternative for this type of clamp a rolling clamp type PRAX can be used.

The fixing is done by welding

On this plate 3 a connection piece 6 is centred and completely welded at the bottom. A connection piece 6 with a length of 10 cm and with a width and thickness of 3 cm. The connection piece 6 is hollow and made of stainless steel and fitted with plastic lids.

Two tubes 10/14 in stainless steel will form the extending pushing rod 10/14.

The first tube 10 on the side of the IV pole , has an inside diameter of 25 mm and a side thickness of 1 mm and a length of 70 cm.

The second tube 14 on the patient's side, also in stainless steel, has an outside diameter of 25 mm and a side thickness of 1 mm and a length of 70 cm.

At 30 cm from the end, on the side of the patient, of tube number two 14 there is an identification holder 12 as can be bought standard with the dimensions 10,5 cm x 4,5 cm, which is glued to the tube. At 10 cm of the end of tube two 14 a button 16 is fitted with, freely available, that connects tube one 10 and tube two 14 to each other. Tube one 10 is fitted with of openings 11 where the button 16 can click in.

These openings 11 are aligned, the first opening 11 is situated at 10 cm from the end of tube one 10 along the patient's side, the following openings 11 are situated at 20, 30, 40 cm of the end of the tube of tube one 10 along the patient's side.

The last 5 cm of the inside of the second tube 14 on the side of the patient , is completely filled up with two components polymer.

Centrally and completely within the axis of the pushing rod 10/14 a prolonged nut 15a of 1 cm length with an inside screw thread of 6 mm is placed, whereby one is careful not to have any polymer entering the nut 15a and the nut 15a almost precisely fits the inside diameter of tube two 14.

The handle 15 is made of plastic and has an inside diameter of 26 cm

Central inside the handle 15, a hole with a 6 mm diameter is drilled into the axis line of the pushing rod 10/14, through which an iron bolt 15 b/c with a round head 15d is placed.

Between the top of the handle 15 and the head of the bolt 15d a protecting round 15f in stainless steel is placed, that is glued to the handle 15.

One has to make sure that there is about half a mm of free game between the handle 15 and the head of the bolt 15d. The bolt 15b/c is fixed into the nut 15a by means of two-components polymer.

There will be a plastic cover plate 15g that hides the head of the screw 15d. The neck of the bolt 15c has no screw thread over at least 0,5 cm.

A protective round 15e comes along the inside of the handle 15 and is glued to it

On tube number two 14, a sign 13 is marked, in non-erasable ink and circular, were the maximum extension is reached. This sign 13 is situated at 10,5 cm of the end on the side of the original IV pole 1.

The hinging piece Fig. 2a/b, 3, that allows the hinging of the pushing rod 10/14 from horizontal to vertical position, is made of a stainless steel tube with a tube wall thickness of 1 mm and an outside of 25 mm, that is worked open with flattened protrusions. The flattened protrusions are on the side of the IV pole 1, the part with the hollow tube is on the side of the patient.

The flattened protrusions Fig 3 end on a rounding with radius 11 mm.

For the construction of the actual hinge in the vertical plane, one uses a tube piece 8a that fits right in between the flattened protrusions and of which the middle axis is a 90 degree angle on the flattened protrusions and coincides with the axis that connects the centre of the radius of the flattened protrusion.

Then, one pulls a second tube 8b over the first tube piece 8a, of which the inside diameter is the same as the outside diameter of the first tube piece 8a. On the left and right of the second tube piece 8b, a spacing ring 8f is fixed and fixed to the first tube piece 8a. The inside diameter of the spacing rings 8f is the same as the outside diameter of the first tube piece 8a.

The width of the second tube piece 8b is optimal at 20mm . The width of the spacing rings 8f is such that their combined width plus the width of the second tube piece 8b is the same as the width of the first tube piece 8a.

After that, one drills a hole through the centre of the radius of the protrusions, with the same diameter as the outside diameter of the first tube piece 8a. After which one welds the first tube 8a to the protrusions (first one drills the hole and then the tube pieces 8a/b are assembled).

Technically more simple but less solid, one can drill a hole with a diameter of 6 mm and inject two components of polymer, so that the first tube 8a is stuck to the protrusions

On this drum, formed by the second, thus outer tube piece 8b, now a stainless steel tube 7b is welded, with also an outside diameter of 25 mm and a length of 10 cm, whereby the centre point of the tube 7b precisely touches the drum, formed by the second, thus outer tube piece 8b.

After the welding, over a width of 2 cm on both sides of the point of contact, a consolidating bridge 7c in two-components polymer is fixed. On both sides of the tube, consequently a free tube end of 3 cm is left.

This cross tube 7b is fixed into the plane that cuts the drum, formed by the second, so outer tube piece 8b, precisely in half and is perpendicular on the axis that runs through the drum, formed by the second, so the outer tube piece 8b. Both 3 cm free ends of the tube 7b of an outside diameter of 25 mm, now are covered with a tube piece 7a of 3 cm in length with an inside diameter of 25 mm and a tube wall thickness of 1 mm in stainless steel. The two pieces 7a, placed on top, with an inside diameter of 25 mm end precisely where the tube 7b with outside diameter of 25 mm ends.

The two loose tube pieces 7a are now welded centrally to the thickening piece 6 with a length of 10 cm and a width and thickness of 3 cm, whereby the plane, that runs through the centre axis of the IV pole 1, also runs through the centre axis of the two welded tube pieces 7a with an inside diameter of 25 mm and the plane that cuts the connection piece 6 precisely in half in the direction of the length, and also coincides with this previously mentioned plane, that runs through the centre axis of the original IV pole 1 as well as through the centre axis of the welded tube pieces 7 a with an inside diameter of 25 mm.

The two tube pieces 7a have to be open on one side and closed on the other side. The bottom piece has to be open at the top. The top piece has to be open at the bottom.

The clamp 5 into which the pushing rod 10/14 is clicked onto the plate 3 when in rest, is standard obtainable. The clamp 5 is of the described type and is fixed by welding and fit for taking in tubes of a diameter of approximately 25 mm

Assembly of the fixating clamps 5 for the pushing rod 10/14 onto the plate 3 or onto the vertical rod, parallel assembled to the original IV pole 1 is done as follows : onto the plate 3 or rod, at 16 cm of the top, a pressure clamp 5 is welded, suitable for the intake of tubes with a 2.5 cm diameter. These clamps 5 are of the described type. Optimally, a connecting piece 5a is assembled between the vertical help rod or -plate 3 or the original IV pole 1 on the one hand and the clamp 5 for the pushing rod 10/14 on the other hand, with a sufficient thickness (6 cm) to facilitate the folding up and fixing of the pushing rod in vertical position.

The drip pipes

The drip pipes are not fixated with guiding brackets 4 but so guided that they can only follow one path.

A first guiding bracket 4 is situated 5 cm below the upper end of the vertical plate 3 or rod.

A second guiding bracket 4 is situated exactly half way the vertical plate 3 or rod.

A third guiding bracket 4 at 30 cm of the end of tube one 10 on the side of the IV pole 1.

A fourth guiding bracket 4 at 5 cm of the end of tube one 10 on the side of the patient.

A fifth guiding bracket 4 is situated at 5 cm before the handle 15 of tube two 14.

The drip clamps 4 have a diameter of 10 mm if the drip pipes have a diameter of 5 mm. The clamps 4 for fixating the drip pipes are glued with whether or not filling glue, for example two-components polymer, so that the fixing on irregular or square tubes is not a problem.

Alternative embodiments

Alternative hinge

The hinge construction of the hinge, that allows to hinge from vertical to horizontal position, can look like the following : instead of using the method as described in the optimal embodiment for getting the horizontal, vertical hinging functioning, one uses a ball bearing.

In the centre of the radius of 11 mm of the flattened protrusions, between which the hinge is assembled, assuring the movement on the vertical plane, centrally and perpendicularly a hole is drilled with a diameter of 6 mm. In this hole, a stylus of 6 mm in diameter and 25 mm in length is placed. After assembly of the actual hinge, this stylus will be welded on the outer side of the flattened protrusions. The stylus is of stainless steel. Centrally on the styles, there will be a ball bearing with an inside diameter of 6 mm and an outside diameter of 20 mm and a width of 20 mm Matching spacing rings with an inside diameter of 6 mm and a width of 2,5 mm keep the ball bearing centred. The ball bearing is pressed into a drum with an inside diameter of 20 mm and an outside diameter of 24 mm. On this drum, a stainless steel tube 7b is welded with also an outside diameter of 25 mm and a length of 10 cm, whereby the centre point of the tube 7b touches exactly the drum around the ball bearing. After the welding, over a width of 2 cm on both sides of the touching point, a consolidating bridge 7c in two-components polymer is put on.

Consequently, on both sides of the tube 7b a free tube end of 3 cm is left. This cross tube 7b is fixed in the plane that cuts the ball bearing exactly in half and which is perpendicular on the axis that runs through the ball bearing. Both free ends of 3 cm of the tube 7b of an outside diameter of 25 mm, now get a tube put over them 7a with a length of 3 cm with inside diameter of 25 mm and tube wall thickness of 1 mm, in stainless steel. The two pieces 7a with inside diameter of 25 mm, and fixated, end exactly where the tube with the outside diameter 25 mm ends.

The two loose tube pieces 7a are now welded centrally on the thickening piece 6 with a length of 10 cm and width and thickness of 3 cm, whereby the plane, running through the middle axis of the IV pole 1, also runs through the middle axis of the two welded tube pieces 7a with an inside diameter of 25 mm and the place that, in length, cuts the connecting piece 6 exactly in half, also coincides with the prior mentioned plane, that runs through the middle axis of the original IV pole 1 as well as through the middle axis of the welded tube pieces 7a with inside diameter of 25 mm. The two tube pieces 7a have to be open on one side and closed on the other side. The bottom one has to be open at the top. The top one has to be open at the bottom.

Alternative connection between the hinge and tube one 10

Tube one 10 is on the side of the IV pole 1 with the hinge, that enables hinging between horizontal and vertical position, is connected through an insertion tube of 10 cm long with an outside diameter, that fits exactly into the inside diameter of tube one and the hinge part, i.o.w. The insertion has the same outside diameter as the inside diameter of tube number one 10 and the hinge part. This insertion sticks into tube number one for 5 cm and into the hinge for 5 cm. It is glued in tube number one 10 as well as in the hinge with two - component polymer.

Alternative for the rotation movement on the handle 15

Possibly, in the connection between the hinge part and tube one 10 that forms the pushing rod 10/14, the rotation around the longitudinal axis of the pushing rod 10/14 can be built in.

The rotating movement that compensate the rotation of the pushing rod 10/14 around its longitudinal axis, can exist of the following construction. (We take the example of a simple pushing rod 10, but also in case of a dual one this is possible).

Along the inside of the tube, that forms the actual pushing rod 10, a protective round 8e with a width or e.g.. 0,5 cm is fixed. This happens twice with a space of e.g. 10 cm by e.g. 3 cm of the end of the tube 10 on the side of the IV pole 1.

The protecting round 8e has an opening the size of the outside diameter of a piece of inner tube 8c on which the vertical - horizontal hinge is fixed. Possibly one can replace the two protecting rounds 8e by pressed constrictions with the same characteristics. On the outside of the tube piece 8c on which the vertical - horizontal hinge is fixed, also two protecting rounds 8d with a width of e.g. 0,5 cm are fixed. This is done in such a manner that they fixate the tube piece 8c without allowing free space. Possibly these two protecting rounds 8d can be replaced by pressed bulges.

Another alternative with the same effect, that uses narrowing that give a good stability Fig 5 a.

Another alternative with the same effect exists in that the tube piece 8c on which the horizontal - vertical hinge is fixed, is shoved e.g. 15 cm inside the first tube, that forms the actual pushing rod 10. With that, the inside diameter of the tube 10, that forms the actual pushing rod 10, and the outside diameter of the tube piece 8c with hinge, are the same. The last 5 cm of the tube piece 8c are narrowed. A ring with a width of 0,5 cm 8d is glued or welded to the end of the narrowed section. On the inside of the tube 10 a ring 8e is assembled that prevents gliding to the front. And possibly there is another ring 8e assembled to the inside of the tube 10, that prevents the sliding backwards. The ring 8d, that is assembled to the outside of the narrowed section, is as it were taken into a clamp by the rings 8e, assembled to the inside of the tube 10.

Even more stability is obtained Fig. 5

Even more stability is obtained Fig. 5 by assembling two rings 8d , with a spacing of 4 cm on the narrowed section on the tube piece 8c with the hinge on it, and for example before both, without free space, by placing a ring 8e that is fixated to the inside of the tube 10 forming the pushing rod 10

A further production - technical simplification of the latter alternative (by extra tube piece) Fig.6 A further production - technical simplification of the latter alternative, exists in that one assembles and fixes, into the first tube piece 8c with the hinge on it, a second help tube piece 19, of which the outside diameter is equal to the inside diameter of the first tube piece 8c with hinge, after which one takes two rings 20/21 with the same diameter as the first tube piece 8c with the hinge. After which one fixates the first ring 20 without spacing, to the inside of the first tube 10 that forms the actual pushing rod 10 and then fixates the second ring 21 to the outside of the second help tube piece 19, whereby the first ring 20 is closest to the IV pole and the second ring 21 is closest to the patient. Possible greasing

All hinges and rotation points can be greased with for example Griffith, Teflon, etc

Alternative without vertical rod 3

Pushing rod 10/14 with hinges, the clamps 5 for fixing the pushing rod 10,14, the clamps 4 for the pipes, can be assembled directly to an original IV pole 1 instead of on a vertical help plate 3 or rod, that can or cannot be disassembled.

Alternative for the extending pushing rod 10/14

Exchangeable pushing rods 10 with a fixed length can be used, whereby the pushing rod 10 is possibly adapted to the arm length of the patient, the leg length of the IV pole, etc. For normal patients and normal standards, for a simple pushing rod 10, a length of 90 cm is the most suited. Alternative welding

The welding that connects the connection piece 6 to the two tube pieces 7a of 3 cm and the welding that fixes onto the vertical plate 3 the clamps 5, serving to click in the pushing rod and the welding that fixes onto the original standard 1, the clamps 2 serving to fix the vertical plate 3 or the vertical rod, can be replaced by gluing them, using industrial glues or products, possibly two components polymers , possible glues or products that fill up . The same goes for the connection between the connecting piece 5a between the clamps 5 for fixing the pushing rod 10/14 and the vertical plate 3 or rod or the original standard 1. Alternative stainless steel

All pieces in stainless steel can also be replaced by aluminium, a non-ferro material, every metal with a protective layer or any hydrocarbon material.

The form of the extending tubes 10/14

The form of the extending tubes 10/14 can be, but does not have to be round. Standard tubes are known in a square or oval form. It is perfectly possible to take completely random diameters. The only condition is that the outside diameter of the second tube 14 fits exactly into the diameter of the first tube 10.

If one uses two round shaped tubes without any extra provision to keep the tubes aligned, one has to pay attention, each time again, to the extending of the tubes, that the alignment between both is correct, because otherwise the drip pipes will move. With square or rectangular tubes or with tubes with random but fitting diameters, this problem does not exist. Possibly, for the fixation of the two tubes in respect to from each other, clamps can be used that receive their clamping functioning from the functioning of a bolt, whereby the nut is attached to the outer tube, and the bolt by fastening it, gives a clamping action on the inner tube, or by a clicking system whereby the clamps is fixed onto the tube with the largest diameter and then pressure is given through a lever system on the tube with the smallest diameter.

For fixating the two tubes, if these are of a round shape, a help piece can also be used, shoved over the two tubes, and stuck to the tube with the largest diameter. Such help pieces are standard use for extendable broomsticks. Possibly, for the fixation, a locking pin can be used

The alignment between the first 10 and the second tube 14 can also be done by tubes that are not round, or by using tubes that are essentially round, but have one or other irregularity in their round shape, whereby this irregularity happens in the inner as well as in the outer tube. The forms, described in the optimal embodiment as well as in the alternative embodiment, can also be obtained by tubes that were obtained through extrusion.

In the inner tube, one can foresee a bulge in the direction of the length, and in the outer tube a slot of the same width, or vice versa.

Instead of only a slot, one could also foresee a corresponding bulge, that is placed above the first bulge, which would certainly improve the solidity.

Also, in the inner tube, one can make a dent in the longitudinal direction with or possibly without changing the diameter of the tube and at the same time make a corresponding dent, in the same way, in the outer tube One could also foresee corresponding bulges. If one changes the diameter of the tube, this can also be achieved by pressing.

Alternative for chain 9

One can replace the chain 9 by a pin 9b — slot 9a construction, whereby a pin 9b is situated at the end on the inside of the tube of the pushing rod 10/14 and a slot 9a is situated on the outside of the fixed tube 8b, which is fixated to the tube 7b and which is part of the hinge for the vertical hinge movement 8, whereby the pin 9b — slot 9a position can be exchanged.
