Description

technical field

The invention relates to a transportable and modular auxiliary device for the medical care of patients, in particular for anaesthesia, intensive care medicine, emergency medicine or for first aid. In addition, the mobile auxiliary device is suitable as a training/exercise device for learning and training in life-sustaining or life-saving measures, in particular first-aid measures, such as learning and training in cardiopulmonary resuscitation on a first-aid dummy or resuscitation dummy or a practice phantom.

State of the art

A wide variety of mobile trans and infusion stands for the medical care of patients are already known from the prior art. Trans and infusion stands are generally designed in such a way that an infusion bag or an infusion bottle can be attached to them, with the infusion bag or infusion bottle containing special infusion solutions, for example to restore cardiovascular functions.

In hospitals, mobile trans and infusion stands are often used, which are equipped with rollers so that the patient can always be supplied with infusion solutions - not only at the bedside, but also on his way out in the fresh air or to examinations. A moveable trans and infusion stand also has the advantage that it can be transported quickly and easily by the staff to the respective hospital room. In the DE 6750494 U and DE 199 05 678 A1 trans and infusion stands with castors are shown as an example.

In contrast, for example in the CN 202459604 U , CN 202637601 U and CN 1456365A Infusion stands disclosed, which are equipped without a chassis or without wheels. In this case, the holding rod, to which the infusion bag or the infusion bottle can be attached, is fixed or, if necessary, detachably fastened to a base plate. Such infusion stands have the disadvantage that, due to their size and weight, they can only be used in clinics or doctor's surgeries, and thus only as an inpatient. Accordingly, stationary infusion stands are only suitable to a limited extent for medical assistance at the scene of an accident, especially on uneven terrain.

In addition, in the DD 78317 A1 describes a transportable and foldable trans and infusion stand, which is used to combat shock and revive people and can be carried in an emergency case. The trans and IV stand comprises a conventional, collapsible stand with a socket for an attachment and an attachment that can be attached to the socket by means of threads, the attachment having a metal disc with any number of holes at the upper end. The holes on the metal disc are used to attach the leather straps to which the snap hooks are attached. The snap hooks serve as a suspension device for the blood or blood substitutes or infusion bags or infusion bottles. Although a trans and infusion stand is provided here, which can be set up on any terrain at the scene of an accident, a secure stand is not guaranteed, especially with blood or blood substitutes or infusion bags or infusion bottles attached to the suspension device.

In addition to the provision of infusion solutions, the transport and positioning of the patient play a major role in medical care, in particular in the emergency or first aid of patients. When positioning the patient, the immobilization of the patient is extremely important on the one hand, and on the other hand the patient must be positioned in such a way that life-sustaining or life-saving measures such as cardiopulmonary resuscitation can be carried out in the best possible way.

Only stretchers, spine boards or resuscitation boards are known from the prior art. Resuscitation boards in particular are designed as a plate-shaped base that is placed under the patient's chest during cardiopulmonary resuscitation and serve to ensure an effective cardiac massage. Spineboards, on the other hand, are used in particular for the rescue transport of injured or injured people with suspected spinal injuries. The injured or injured person is placed supine on the spine board before being fixed for transport with a personal fixation system (also called "spider"), consisting of a head fixation system and a multi-part belt system. As a result, the injured or injured person can be immobilized by the spineboard on the one hand, and on the other hand the spineboard can also be used as a relocation and transport device due to its size or dimensions.

In the U.S. 8,443,472 B2 , CN 201719452 U , CN 202497352 U and CN 203089583 U stretchers are disclosed by way of example, on their frames a removable trans and infusion stand can be mounted. Since stretchers or spineboards are used not only for treatment but also for transporting lying patients, they are quite large in size so that the patient's entire body rests on the stretcher or spineboard. Another disadvantage of conventional stretchers or spine boards is that the trans and infusion stands can only be mounted on the frame, which greatly restricts the positioning of the trans and infusion stands.

The types of trans and infusion stands described have various disadvantages, on the one hand the stability of the typical trans and infusion stands is far too low, which means that the use of the trans and infusion stands on uneven terrain or underground is not possible. Especially in emergency or first aid, where things are often very hectic, it is essential that the trans and infusion stand has a secure footing. Another problem is that the assembly of one or more support rods, in particular trans and infusion stands, on a stretcher, spine board, resuscitation board or a similar stretcher is often extremely complex and cumbersome. Especially against the background of emergency and first aid, where every second counts, a time-consuming assembly of the support rod, in particular the trans and infusion stand, on the frame of the stretcher is very problematic.

Presentation of the invention

The object of the present invention is therefore to provide a transportable and modular auxiliary device for the medical care of patients, which can be set up and dismantled quickly and easily and ensures a secure footing, in particular during medical care. According to the invention, this object is achieved by the device according to independent claim 1 . Further advantageous aspects, details and configurations of the invention result from the dependent claims, the description and the drawings.

The present invention provides a mobile auxiliary device for the medical care of patients, comprising a base plate that can be placed on the floor and has a support surface for a patient and at least one receiving unit for fastening at least one holding rod. Furthermore, the auxiliary device comprises at least one support bar for attaching aids from the medical and/or hygiene sector, the support bar being detachably attachable to the receiving unit of the base plate via a bayonet catch.

An essential aspect of the invention is that the base plate forms a support surface for a patient, so that the patient can be laid down on the support surface at the scene of the emergency, in particular at the site of an accident or accident, preferably with his torso or torso. The auxiliary device is stabilized by the weight of the patient, so that the auxiliary device cannot tip over while the patient is being cared for. In addition to the medical care of patients, in particular anesthesia, intensive care medicine, emergency medicine or first aid, the auxiliary device is also suitable as a training/exercise device for learning and practicing life-sustaining or life-saving measures, in particular first-aid measures. For example, when learning and training in first-aid measures, a first-aid dummy or resuscitation dummy or a training phantom is placed on the contact surface of the base plate before the corresponding measures such as cardiopulmonary resuscitation are started. Thanks to the stable auxiliary device, it is possible for the first time that the support bar for attaching aids from the medical and/or hygiene sector, which is mounted on the stable base plate when the auxiliary device is in use, can be set up in the immediate vicinity or directly next to the patient . Advantageously, aids such as protective/splash protection panes, in particular Plexiglas panes, holders for respirators, storage containers or trays for storing medical cutlery and/or instruments and/or syringes and other items for medical care, holders for in particular infusion bags, infusion bottles or blood or Blood substitutes can be placed in the immediate vicinity of the patient caring for them.

In addition, the base plate provides helpers such as doctors, paramedics and first-aiders with a hard base for carrying out first-aid measures at any location. A hard surface is essential for cardiopulmonary resuscitation (resuscitation) to be as effective as possible and for increasing the chances of success when carrying out cardiac massage. The base plate thus fulfills the function of a so-called resuscitation board.

Furthermore, the invention brings with it the advantage that the auxiliary device can be set up/dismantled quickly and easily at the site of the emergency, in particular at the site of an accident or accident. According to the invention, a Bayonet catch provided, by means of which the at least one support rod is attached to the at least one receiving unit of the base plate. In the present case, the bayonet lock has an axis of rotation and consists of a first lock part, which is arranged on the holding rod, and a second lock part, which is arranged on the respective receiving unit of the base plate. To mount a retaining rod on a receiving unit of the base plate, the first locking part of the retaining rod only has to be brought into engagement with the second locking part of the receiving unit before the bayonet lock is locked or unlocked by turning the retaining rod clockwise or counterclockwise. The installation of the handrail can therefore be carried out in the shortest possible time and by one person. Another advantage is that the auxiliary device can be assembled and disassembled without tools.

So that the auxiliary device has a low weight and is easy to transport, the base plate is made of preferably light and stable material, in particular plastic, plastic composite material, glass fiber reinforced plastic, hard plastic, etc. The material used for the base plate is usually non-magnetic and also not electrically conductive, which means that the base plate is suitable, for example, for computed tomography or magnetic resonance tomography. It is also advantageous if the material used has low thermal conductivity, so that the base plate offers the patient protection against cooling down or protection from the cold. In a first embodiment, the shape of the base plate is adapted to the shape of a human torso or torso, as a result of which the central part of the base plate has a waisted design. The waisted shape of the base plate ensures that on the one hand a sufficient support surface is made available for the upper body of the patient and on the other hand the weight of the base plate is kept as low as possible. However, the shape of the base plate is in no way limited to the shape of a human trunk or torso. Rather, the base plate can also have the shape of an ellipse, a circle, a sector of a circle, a triangle, a quadrilateral, a square, a rectangle, a trapezoid, a parallelogram or a polygon. In a further preferred embodiment variant, the base plate is fan-shaped or part-circular or in the form of a circular sector, the circular sector preferably enclosing an angle of between 15 degrees and 60 degrees, in particular of 25 degrees and 40 degrees. In turn, the corners are advantageously rounded off in the case of angular shapes of the base plate.

It is also advantageous that the second closure part of the bayonet closure is formed by at least one cutout made in the base plate and designed in the shape of a keyhole. The keyhole-shaped recess preferably has a first, slot-shaped recess section which has a defined width, and a second, circular recess section which has a defined diameter, the diameter of the second recess section being greater than the width of the first recess section. The keyhole-shaped recess is made in the top side of the base plate and extends at least partially over the thickness of the base plate, also referred to as the material thickness, in the direction of the underside of the base plate. Depending on the embodiment of the recess, it can either extend over the entire material thickness of the base plate or only to a certain depth of the base plate. Depending on the material used for the base plate, the material thickness of the base plate is preferably between 1 cm and 10 cm, in particular between 1.5 cm and 5 cm.

Furthermore, the end of the recess remote from the support surface has a guide groove for receiving and guiding the first closure part. The guide groove preferably runs in a plane that runs parallel to the top side of the base plate and is dimensioned such that an engagement element of the first closure part can be accommodated and guided during a clockwise or counterclockwise movement. Depending on whether the recess only extends to a certain depth of the base plate or completely over the material thickness of the base plate, the guide groove is either inside the base plate, i.e. between the upper side of the base plate and the lower side of the base plate, or on the lower side of the base plate. The at least one recess is particularly preferably arranged on a circular path arranged concentrically to the axis of rotation of the bayonet lock and extends along a circular path section of the circular path.

In order to establish the most secure and stable connection possible between the holding rod and the base plate, the second closure part has two or more recesses, the recesses being arranged on the same circular path and spaced apart from one another along the circular path. Two to five, in particular three or four, recesses are advantageously arranged on the second closure part. All recesses of the second closure part are oriented in one or the same direction, ie the circular recess section of a first recess is opposite the slot-shaped recess section of a second recess, the circular recess portion of a second recess faces the oblong-shaped recess portion of a third recess, and so on.

In a further preferred embodiment, the first closure part of the bayonet closure is formed by at least one bolt-shaped or peg-shaped engagement element, which has a particularly cylindrical shank section and a holding section that is larger in diameter than the shank section. The retaining section is preferably designed like a disk and dimensioned such that it can be inserted into the respective circular recess section of the recess of the second closure part and can be moved along the guide groove of the recess when the retaining rod is rotated clockwise or counterclockwise.

Preferably, a counter-clockwise rotation of the retaining rod causes the bayonet catch to be locked, i.e. the preferably disc-shaped retaining section of the engagement element of the first closure part moves along the guide groove from the circular recess section in the direction of the slot-shaped recess section of the recess of the second closure part. The bayonet catch is fully locked as soon as the holding section has reached the end of the slot-shaped recess section of the recess of the second closure part. When the bayonet catch is in the locked state, the retaining rod cannot then be moved in the direction of the axis of rotation or in the direction of the longitudinal axis of the retaining rod; the retaining rod is therefore firmly mounted on the base plate. A rotation of the retaining rod in the opposite direction, i.e. clockwise, causes the bayonet catch to be unlocked or released again, i.e. the preferably disk-shaped retaining section of the engagement element of the first closure part moves again along the guide groove in the direction of the circular recess section of the second closure part. Once the holding portion has reached the circular recessed portion, the engaging member can be moved out of the circular recessed portion. The recesses on the second locking part can also be oriented in the opposite direction, so that a clockwise rotation of the support rod causes the bayonet catch to be locked and that a counterclockwise rotation of the support rod causes the bayonet catch to be unlocked or released.

It is also advantageous that the number of engagement elements of the first closure part corresponds to the number of recesses of the second closure part, with preferably between two and five, in particular three or four recesses being provided on the first closure part. If, for example, three recesses are provided on the second closure part, then the first closure part has three corresponding engagement elements.

When assembling the support rod to the base plate, the engaging elements of the first locking part must be inserted into the respective circular recessed portions of the second locking part. In order to facilitate assembly of the retaining rod, the receiving unit comprises at least one centering and guide recess and the retaining rod at least one centering and guide projection, the centering and guide projection being at least partially received in the centering and guide recess when the bayonet catch is in the locked state. The centering and guiding recess is preferably designed as a circular recess or opening which is made centrally in the receiving unit, i.e. the centering and guiding recess is arranged axially to the axis of rotation of the bayonet lock. The centering and guiding projection is preferably of cylindrical design.

In a preferred embodiment, the retaining rod comprises a base part on the free end facing the base plate, the base part having a support surface with which the retaining rod is supported on the base plate when the bayonet catch is in the locked state. The cross section of the support surface is a multiple, preferably two to ten times, the cross section of the support rod. The large support surface ensures that the handrail is held or stands as securely as possible on the base plate when installed. The secure position of the handrail is particularly important when medical and/or hygiene aids are attached to the handrail. The support surface of the base part does not have to be designed as a circle, rectangle, square, rectangle, polygon, triangle, etc., rather the base part can have several, in particular three, radially extending and preferably evenly distributed support arms. An extremely firm stand of the retaining rod can also be achieved by the support surface being distributed over several, in particular three, support arms.

The base part represents part of the support rod and can be firmly connected to the support rod. In an alternative embodiment, the base part is designed in such a way that the retaining rod faces the base plate free end is received in the base part or can be inserted. If the retaining rod has a base part, then the first closure part of the bayonet closure and, as a rule, the centering and guiding projection are arranged on the base part. In a particularly preferred embodiment, the base part has a sleeve-like recess with an internal thread for each engagement element of the first closure part of the bayonet closure, into which the respective engagement element can be screwed. For this purpose, the respective engagement element has a corresponding external thread on the end of the shank section facing the base part. If the engagement elements are releasably attached to the base part and the retaining rod is inserted or releasably attached to the base part, the modularity of the auxiliary device is further increased, which means that individual components or parts of the auxiliary device can be easily replaced in the event of wear or a defect.

In a development of the invention, the base plate is designed in two or more parts, with the base plate having at least a first base plate part and a second base plate part. Advantageously, the at least one base plate part and the at least second base plate part are mounted rotatably on a rotating and locking unit, so that the first and second base plate parts can be pivoted relative to one another about an axis of rotation running parallel to the axis of rotation of the bayonet catch. The rotating and locking unit according to the invention preferably consists of at least one base plate with a preferably cylindrical receiving section that extends in the axial direction or in the direction of the axis of rotation of the rotating and locking unit, the receiving section being dimensioned such that the base plate parts can be received. The base plate parts in turn have a corresponding recess in order to be able to be accommodated by the turning and locking unit. Furthermore, the rotating and locking unit has at least one receiving unit, which is used on the one hand to fasten a support rod, and on the other hand the base plate parts are fixed in their position by the mounted support rod.

According to the invention, when the auxiliary device is not in use, the base plate parts are pivoted in such a way that they are arranged congruently one above the other. Due to the small dimensions when folded, the auxiliary device is easy to transport and can also be stowed away to save space. When in use, the base plate parts are now pivoted in opposite directions, ie away from one another, so that the base plate parts are preferably in a V-shape relative to one another. A particularly good and stable stand of the auxiliary device is achieved when the longitudinal axis of the two base plate parts preferably enclose an angle between 20 degrees and 140 degrees, in particular between 30 degrees and 90 degrees. Such an auxiliary device with base plate parts that can be pivoted about an axis of rotation has the advantage that the helpers such as doctors, paramedics or first-aiders can align the base plate parts individually depending on the intended use, the condition of the ground, and the space available at the emergency site.

Particularly preferably, the base plate or the first and second base plate part has at least one recessed grip in the edge region designed as an opening for holding and carrying the auxiliary device and/or the base plate. The recessed grips are positioned and dimensioned in such a way that they can be gripped easily and securely with the hand. It is advantageous if two or more, in particular four to ten, recessed grips are incorporated into the base plate, as a result of which the helper has a large number of grip options available.

It is also advantageous if the at least one recording unit is preferably arranged in the edge area of the base plate, in such a way that the recording unit is also accessible when the patient is lying or is placed on the supporting surface of the base plate. Two or more receiving units are preferably arranged on the base plate. The more receiving units are arranged on the base plate, the more mounting positions are available to attach the at least one support rod to the base plate. The at least two receiving units are particularly preferably arranged mirror-symmetrically to the longitudinal axis of the base plate. If several receiving units and/or several recessed grips are provided, these can also be arranged mirror-symmetrically to the longitudinal axis of the base plate. In this context, it would also be conceivable to arrange the receiving units in pairs in order to provide two directly adjacent mounting positions for at least one support rod at one point.

The at least one retaining rod is preferably designed as a preferably height-adjustable telescopic rod, so that the retaining rod has a small transport or packing size when it is retracted. In addition, the height of the handrail can be individually adjusted depending on the situation and the aids to be attached. In the extended state, the support rod has a preferred length of between 50 cm and 220 cm, in particular between 80 cm and 80 cm, in the longitudinal direction or in the direction of the axis of rotation of the support rod 150cm up. In a particularly preferred embodiment, the holding rod has a length of between 100 cm and 120 cm.

Finally, at least one aid from the medical and/or hygiene and/or advertising sector can be attached to at least one support rod, the aid being in particular a protective/splash protection pane, in particular a Plexiglas pane, holder for respirators, storage containers or trays for storage medical cutlery and/or instruments and/or syringes and other items for medical care, holders for infusion bags, infusion bottles, blood or blood substitutes or oxygen bottles. Aids also include means that increase safety at the scene of the accident, such as flags or warning signs to make the auxiliary device more visible, or advertising materials, such as billboards or advertising pennants.

Particularly in the field of emergency medicine or in the field of first aid, it is necessary for a high level of hygiene to be guaranteed at the location of the emergency care or at the location of the first aid service or at the scene of the accident. Therefore, the mobile auxiliary device not only serves to care for the patient, but also as a hygiene protection, in which at least one protective/splash protection screen can be attached to the at least one support rod. The attachment of the at least one protection/splash protection pane to the support rod is preferably carried out by means of at least one locking or clamping means. For example, a quick-release clamp is used as the clamping means, which on the one hand holds the protective/splash protection pane and on the other hand can be clamped to the support rod. The quick-clamp closure encompasses the support rod and has at least one locking wheel, by means of which the quick-clamp closure can be tightened. The quick-release clamp offers the advantage that the protection/splash protection screen can be attached to the support rod at any height and the protection/splash protection screen can be positioned as desired perpendicular to the longitudinal axis or to the axis of rotation of the support rod.

A particularly high level of hygiene protection is achieved if several handrails, each with at least one protective/splash protection pane, are mounted on the base plate. If the protection/splash protection panes are aligned accordingly, the protection/splash protection panes offer hygienic protection to the patient to be cared for and/or to other helpers. The special feature is that the protective/splash protection screen can be attached in the immediate vicinity of the patient. This is extremely important in anesthesia, intensive care medicine, emergency care or first aid, since helpers such as doctors, paramedics or first aiders are often less than 50 cm away from the patient. It would also be conceivable to arrange the latching and clamping means on two opposite end faces of the protective/spray protection pane, so that the protective/spray protection pane can be fastened with its first end face to a first retaining rod and with its second end face to a second retaining rod.

In an alternative embodiment, the protective/splash protection pane has at least one latching lug on at least one end face and the holding rod has at least one corresponding latching recess, or vice versa. The protective/splash protection screen can be inserted or hung into the corresponding locking recess on the support rod by means of the at least one locking lug.

Ways to carry out the invention

1 the reference number 1 describes a transportable and modular auxiliary device for medical care, in particular anesthesia, intensive care, emergency care or first aid for patients. The auxiliary device 1 according to the invention is primarily used to ensure that patients at an emergency location or at the scene of an accident can be given first medical aid by a person, in particular a doctor, paramedic or first aider. Medical care includes, for example, cardiopulmonary resuscitation, stopping bleeding, using a ventilator, using a defibrillator, providing a transfusion or infusion or canned blood or blood substitutes, administering medication, etc.

The auxiliary device 1 according to the invention consists of a base plate 2 extending in the longitudinal direction LA with a support surface for a patient, having a base plate underside 2.1 and a base plate upper side 2.2 opposite the base plate underside 2.1, the base plate 2 being placed on the floor or subsurface with the base plate underside 2.1 when in use becomes. So that the base plate 2 rests as well as possible on the floor or subsurface, the base plate underside 2.1 is planar or level. In the present case, the surface of the upper side of the base plate 2.2 is essentially the contact surface for the patient. The base plate 2 has a material thickness D of between 1 cm and 10 cm, in particular between 1.5 cm and 5 cm, and preferably consists of light and stable material such as plastic, plastic composite material, glass fiber reinforced plastic, hard plastic, etc. The material used for the base plate 2 is usually non-magnetic and also not electrically conductive, which means that the base plate 2 is suitable, for example, for computed tomography or magnetic resonance tomography. In addition, the material used has the property that it has good cold and heat insulation. Cold and heat insulation plays a particularly important role when the floor temperature is low. If the patient to be cared for is placed on the support surface of the base plate, the base plate also serves as protection against the cold if the underground or floor is at low temperatures.

According to the 1 , 2 , 6 and 7 the shape of the base plate 2 is adapted to the shape of a human torso or torso, as a result of which the central part of the base plate 2 has a waisted design. The waisted shape of the base plate 2 ensures that on the one hand a sufficient support surface is made available for the upper body of the patient and on the other hand the weight of the base plate 2 is kept as low as possible. However, the shape of the base plate 2 is in no way limited to the shape of a human trunk or torso. Rather, the base plate 2 can also have the shape of an ellipse, a circle, a sector of a circle, a triangle, a quadrilateral, a square, a rectangle, a trapezoid, a parallelogram or a polygon. In 3 a base plate 2, which is designed in the shape of a fan or part circle or in the shape of a circular sector, is shown by way of example. Advantageously, with angular shapes of the base plate 2, the corners are rounded, as in 4 is shown. In 3 1 shows a base plate 2 in the form of a sector of a circle, the angle of the sector of a circle preferably being between 15 degrees and 60 degrees, in particular between 25 degrees and 40 degrees.

In the embodiment according to the 1 and 2 6 and 7 and the waisted base plate 2 shown in the exemplary embodiment according to FIG 4 The rectangular base plate 2 shown preferably has a length L between 70 cm and 150 cm, in particular between 80 cm and 120 cm and preferably a width B between 20 cm and 100 cm, in particular between 40 cm and 70 cm. The length L of the base plate 2 according to 3 on the other hand, is preferably between 20 cm and 80 cm, in particular between 25 cm and 40 cm.

Furthermore, the base plate 2 has at least one receiving unit 4 for attaching at least one support rod 3, with the receiving unit 4 preferably being arranged at the edge region of the base plate 2 in such a way that the receiving unit 4 is also accessible when the patient is on the supporting surface of the Base plate 2 is or is placed. Depending on the embodiment of the base plate 2, two or more receiving units 4 can also be arranged on the base plate 2. The more receiving units 4 are provided on the base plate 2, the more mounting positions are available to mount the at least one support rod 3 on the base plate 2. It has proven to be extremely practical to arrange the multiple receiving units 4 in pairs on the base plate, i.e. two receiving units 4 are arranged directly adjacent to one another and/or to arrange the receiving units 4 on opposite sides of the base plate 2.

In order to hold and carry the auxiliary device 1 and/or the base plate 2, at least one recessed grip 19 which is arranged in the edge region of the base plate 2 and is preferably designed as an opening is also provided. Two or more recessed grips 19 are preferably distributed on the base plate 2 . In order to also be able to use the auxiliary device 1 as a stretcher for transporting a patient or for transferring a patient, the recessed grips 19 are designed and dimensioned in such a way that they can be securely gripped with the hand. The recessed grips 19 can also be used to enable the patient placed on the supporting surface to hold on during transport or during repositioning.

In the embodiment according to 1 a total of eight recessed grips 19 and five receiving units 4 are provided on the base plate 2, these being arranged mirror-symmetrically to the longitudinal axis LA or axis of symmetry, so that there are two receiving units 4 and four recessed grips 19 on each side of the axis of symmetry. While the two recording units 4 are located on the upper part, i.e. on the side facing the patient’s head, of the base plate 2, one recording unit 4 is in the middle of the lower part, i.e. on the side facing the patient’s feet, in the base plate 2 brought in. This results in numerous mounting positions for attaching the at least one support rod 3 and numerous gripping positions for holding and carrying the auxiliary device 1 and/or the base plate 2. The arrangement and number of the receiving units 4 and the recessed grips 19 can vary depending on the size and/or shape and/or or the intended use of the base plate 2 vary greatly.

In addition, the auxiliary device 1 comprises at least one holding rod 3, to which aids 15 from the medical and/or hygiene sector can be attached. Aids within the meaning of the invention are all add-on parts that are required for patient care or compliance with hygiene when caring for patients, such as protective/splash protection panes, in particular Plexiglas panes, holders for respirators, storage containers or trays for storing Medical cutlery and/or instruments and/or syringes and other items for medical care, holders for in particular infusion bags, infusion bottles, blood or blood substitutes or oxygen bottles. However, attachment parts also include means that increase safety at the scene of the accident or the scene of the accident, such as flags or warning signs to make the auxiliary device more visible, or advertising material, such as billboards or advertising pennants.

According to the invention, the retaining rod 3 is fastened to a receiving unit 4 of the base plate 2 via a bayonet catch 5. The bayonet catch 5 has an axis of rotation RA, which extends along the longitudinal axis of the retaining rod 3, with the bayonet catch 5 being locked by rotation in a first direction and is unlocked by rotating it in a second direction. In the present case, the bayonet lock 5 consists of a first lock part 5A, which is arranged on the retaining rod 3, and a second lock part 5B, which is arranged on the respective receiving unit 4. The reverse arrangement of the first and second closure parts 5A, 5B would also be conceivable, so that the second closure part 5B is arranged on the holding rod 3 and the first closure part 5A is arranged on the receiving unit 4 (not shown in the figures).

The second closure part 5B of the bayonet closure 5 is presently formed by at least one recess 5B.1 introduced into the top side 2.2 of the base plate, which extends in the direction of the bottom side 2.1 of the base plate and is designed in the shape of a keyhole. The keyhole-shaped recess 5B.1 has a first, slot-shaped recess section 6.1 with a width b and a second, preferably circular recess section 6.2 with a diameter d, the diameter d of the recess section 6.2 being greater than the width b of the recess section 6.1. Depending on the embodiment, the recess 5B.1 can extend over the entire material thickness D of the base plate 2 or only to a depth t of the base plate 2, with the recess 5B.1 ending at a depth t within the base plate 2.

Irrespective of whether the recess 5B.1 extends over the entire material thickness, as exemplified in 5 shown, or the recess 5B.1 only extends to a depth t, the recess 5B.1 has a guide groove 17 at the end remote from the bearing surface, which is designed in such a way that an engagement element 5A.1 of the first closure part 5A recorded and can be performed in the direction of rotation RA and counter to the direction of rotation RA of the bayonet catch 5. In 5 the recess 5B.1 extends over the entire material thickness D of the base plate 2, while the guide groove 17 is introduced into the underside 2 of the base plate. The width of the guide groove 17 is selected in such a way that it corresponds at least to the diameter d of the recess section 6.2. The at least one recess 5B.1 is preferably arranged on a circular path K arranged concentrically to the axis of rotation RA of the bayonet catch 5 or to the longitudinal axis of the retaining rod 3 and extends along a circular path section KA of the circular path K.

The second closure part 5B preferably has two or more, in particular three or four, recesses 5B.1, 5B.2, 5B.3, with the recesses 5B.1, 5B.2, 5B.3 being arranged on the same circular path K and along the circular path K spaced apart from each other. All recesses 5B.1, 5B.2, 5B.3 of the respective second closure part 5B are directed in the same direction, ie the recess section 6.1 of a first recess 5B.1 is the recess section 6.2 of a second recess 5B.2, the recess section 6.1 of the second recess 5B.2 faces the recess section 6.2 of a third recess 5B.3, etc.

In contrast, the first closure part 5A of the bayonet closure 5 is formed by at least one bolt or peg-shaped engagement element 5A.1, the engagement element 5A.1 having a particularly cylindrical shank section 7 and a holding section 8 that increases in diameter compared to the shank section 7 . The holding section 8 of the engagement element 5A.1 is dimensioned such that it can be inserted into the recess section 6.1 of a first recess 5B.1 and rotated clockwise or counterclockwise along the guide groove 17 for locking/unlocking.

In the embodiment according to 1 until 4 and 6 and 7, rotating the retaining rod 3 counterclockwise causes the bayonet catch 5 to be locked, ie the retaining section 8 of the engagement element 5A.1 moves along the guide groove 17 from the recess section 6.2 in the direction of the recess section 6.1 of the recess 5B.1 . The bayonet catch 5 is fully locked as soon as the holding section 8 has reached the end of the recess section 6.1 of the recess 5B.1. When the bayonet catch 5 is in the locked state, the retaining rod 3 cannot be moved in the direction of the axis of rotation RA or in the direction of the longitudinal axis of the retaining rod 3 ; the retaining rod 3 is therefore firmly mounted on the base plate 2 . A rotation of the retaining rod 3 in the opposite direction, ie clockwise, causes the bayonet catch 5 to be unlocked or released again, ie the retaining section 8 of the engagement element 5A.1 moves along the guide groove 17 again in the direction of the recess section 6.2. As soon as the holding section 8 has reached the recess section 6.2, the engaging element 5A.1 can be moved out of the recess section 6.2.

The number of engagement elements 5A.1, 5A.2, 5A.3 of the first closure part 5A usually corresponds to the number of recesses 5B.1, 5B.2, 5B.3 of the second closure part 5B, with preferably two to five, in particular three to four recesses 5B.1, 5B.2, 5B.3 and engaging elements 5A.1, 5A.2, 5A.3 are provided. The several engagement elements 5A.1, 5A.2, 5A.3 are arranged in such a way that each engagement element 5A.1, 5A.2, 5A.3 when mounting the retaining rod 3 first in a respective recess section 6.2 of the recesses 5B.1 , 5B.2, 5B.3 can be introduced.

Furthermore, the receiving unit 4 comprises at least one centering and guiding recess 9 and the holding rod 3 at least one centering and guiding projection 10 corresponding to the centering and guiding recess 9. In the locked state of the bayonet catch 5 the centering and guiding projection 10 of the holding rod 3 is at least partially received in the centering and guide recess 9 of the receiving unit 4. The centering and guide recess 9 and the centering and guide projection 10 make it much easier to mount the holding rod 3 on the receiving unit 4 .

In addition, the support rod 3 can be equipped with a base part 11 on the free end facing the base plate 2 . Depending on the embodiment, the base part 11 can be connected to the holding rod 3 in a fixed or detachable manner. In 8th it can be seen that the base part 11 has a recess 20 which extends in the axial direction or in the direction of the axis of rotation RA and in which the holding rod 3 can be accommodated or inserted. If the holding rod 3 is equipped with a base part 11, the first closure part 5A and/or the centering and guiding projection 10 are located on the base part 11.

The base part 11 has a support surface 12 with which the holding rod 3 is supported on the base plate 2 when the bayonet catch 5 is in the locked state. The larger cross-sectional area of the base part 11 compared to the support rod 3 ensures that the support rod 3 stands securely. In this case, the larger the support surface of the base part 11, the safer the position of the retaining rod 3 in the assembled state. The cross section of the support surface 12 is preferably two to ten times the cross section of the holding rod 3. In an alternative embodiment according to FIG 9 until 11 the base part 11 has at least three support arms 14 extending in the radial direction. In order to achieve as firm a position as possible for the retaining rod 3, the support arms 14 are preferably arranged at an equal distance from one another, that is to say offset by approximately 120 degrees.

According to 8th are the engagement element 5A.1, 5A.2, 5A.3 of the first closure part 5A releasably over a threaded connection attached to the base part 11. For this purpose, the base part 11 has a sleeve-like recess 21 with an internal thread for each engagement element 5A.1, 5A.2, 5A.3, while the respective engagement element 5A.1, 5A.2, 5A.3 on which the base part 11 facing end of the shaft portion 7 is provided with an external thread. The engagement elements 5A.1, 5A.2, 5A.3 can accordingly be screwed into the respective sleeve-like recess 21 of the base part 11. Due to the releasable attachment of the engagement element 5A.1, 5A.2, 5A.3 to the base part 11, the engagement element 5A.1, 5A.2, 5A.3 can be replaced in the event of wear or a defect on the one hand, on the other hand different engagement elements 5A .1, 5A.2, 5A.3 are screwed into the sleeve-like recess 21 base part 11. So the engagement element 5A.1, 5A.2, 5A.3 depending on the material thickness D of the base plate 2 or depth and / or shape of the recess 5B.1, 5B.2, 5, B.3, for example, in length or differ in the design of the holding portion 8.

Furthermore, the base plate 2 can be designed in two or more parts, as in 5 shown. In the two-part variant according to 5 the base plate 2 consists of a first base plate part 2A and a second base plate part 2B, the two base plate parts 2A, 2B being rotatably mounted on a rotating and locking unit 14. The rotating and locking unit 14 essentially consists of a base plate 22 with a preferably cylindrical or columnar receiving section 23, the receiving section 23 being dimensioned such that the base plate parts 2A, 2B can be received. The base plate parts 2A, 2B each have a recess in order to be able to be plugged onto the cylindrical or columnar receiving section 23 of the turning and locking unit 14 . In addition, the rotating and locking unit 14 has at least one receiving unit 4 for attaching at least one holding rod 3 . According to the invention, the base plate parts 2A, 2B can be pivoted about an axis of rotation RA1 running parallel to the axis of rotation RA, so that the base plate parts 2A, 2B can be pivoted when the auxiliary device 1 is not in use in such a way that they lie congruently one on top of the other and the base plate parts 2A, 2B when the auxiliary device is in use 1 can be pivoted in such a way that the base plate parts 2A, 2B can be moved in opposite directions, ie away from one another. After pivoting the base plate parts 2A, 2B from the non-use position into the use position, the base plate parts 2A, 2B are fixed in their position by fastening the retaining rod 3. A particularly firm stand of the base plate 2 is achieved when the longitudinal axes LA of the two base plate parts 2A, 2B preferably enclose an angle α between 20 degrees and 140 degrees, in particular between 30 degrees and 90 degrees. The base plate parts 2A, 2B can be pivoted individually by the user or doctor, paramedic or first aider depending on the intended use, the condition of the ground, and the space available at the scene of the accident. The base plate parts 2A, 2B have a length L and a width B, the length L preferably being between 25 cm and 60 cm, in particular between 25 cm and 35 cm, and the width B preferably being between 5 cm and 20 cm, in particular between 7 cm and is 10 cm.

In a further preferred embodiment, the support rod 3 is designed to be adjustable in height, so that the support rod 3 has a small transport or packing size, and on the other hand the length of the support rod 3 can be adjusted as required. For this purpose, the support rod 3 is designed as a preferably height-adjustable telescopic rod. In the extended state, the holding rod 3 has a preferred length of between 50 cm and 220 cm, in particular between 80 cm and 150 cm. In a particularly preferred embodiment, the holding rod 3 has a length of between 100 cm and 120 cm.

Furthermore, at least one aid 15 from the medical and/or hygiene sector and/or safety and/or advertising sector can be attached to the at least one holding rod 3 . Aids 15 such as protective/splash protection panes 16, in particular Plexiglas panes, holders for in particular infusion bags, infusion bottles, canned blood or blood substitutes or oxygen bottles, holders for respirators, storage containers or trays for storing medical cutlery and/or instruments and/or syringes and others Items for medical care, or flags or warning signs for better visibility of the auxiliary device, or billboard or advertising pennant can be attached to the support rod in different ways. Individual aids 15 such as the holder for infusion bags or infusion bottles can be hung or hooked into the holding rod 3. The holder for the infusion bags or infusion bottles can be designed, for example, as an attachment in the form of a bottle cross or as a hanging part in the form of a bottle hook. The attachment can also be a typical grappling hook for an IV holder.

As per the illustrations 6 and 7 As can be seen, a protective/spray protection disc 16 is releasably attached to each retaining rod 3 . The attachment of the protection / splash guard disc 16 is preferably carried out by means of a clamp or snap-in connection. In the present embodiment according to 6 and 7 a quick-release clamp 23 is arranged on the protection/splash protection pane 16 , with the quick-release clamp 23 enclosing the holding rod 3 during assembly and being braced by a locking wheel 24 . Optionally, at least one latching lug 25 can be provided on the protective/splash protection pane 16 and at least one latching recess correspondingly can be provided on the retaining rod 3, or vice versa. In the embodiment according to 12 the protective/spray protection panel 16 preferably has three latching lugs 25 which are arranged on the end face 17.1 of the protective/spray protection panel 16 facing the holding rod 3. When fastening the protection/splash protection pane 16 to the support rod 3, the locking lugs 25 are hung or hooked into corresponding locking recesses on the support rod 3. The size of the protection/splash protection pane 16 can vary depending on the application and the size of the base plate 2. The width of the in 12 The protective/spray protection pane shown as an example extends from the end face 17.1 to the end face 17.2, the width preferably being between 40 cm and 60 cm and the height preferably being between 40 cm and 80 cm.

The use of protective/splash protection panes 16 can significantly improve hygiene in the immediate care of the patient. The protection/splash protection discs 16 can be arranged in such a way that a high level of hygiene can be guaranteed on site or at the accident site/site between the helper, such as a doctor, paramedic or first aider and the patient, or between several helpers. The attachment is particularly stable if the protective/spray protection panes 16 each have at least one clamping or locking means on the two opposite end faces 17.1, 17.2, so that the protective/spray protection pane 16 can be attached to two different holding rods 3.

The auxiliary device according to 13 also has a storage unit in the form of a tray or storage bin. The storage unit serves to store medical cutlery and/or instruments and/or syringes and other objects that are required for medical care. The storage unit is advantageously equipped with a universal insert, the universal insert being designed, for example, to hold syringes and the like and/or to accommodate needle boxes, utensil cups, swab cups or other medical utensils. The storage unit can be a commercially available universal syringe tray, with additional clamping or latching means being arranged on it in order to be able to attach the syringe tray to the at least one holding rod 3 .
