Definitions
- Positioning device for positioning a human head for eye examination and / or treatment
- the invention relates to a positioning device according to the preamble of patent claim 1 and an eye socket cover for a positioning device.
- the object of the invention is. to create a device with which the attending physician can carry out eye examinations and / or treatments in a simple manner.
- the object is achieved by creating a positioning device for positioning the human head with a forehead support and a chin rest part, on the control elements of which an orbital cover unit with an eye patch can be attached. which can be swiveled in against the eye socket of the eye that is not to be examined or treated.
- the direct covering of the eye in the eye socket with the eye patch prevents the eye not to be examined from moving back and forth by light sources and other stimuli.
- the other eye to be examined can now easily z. B. be fixed on a brand and remains fixed on it.
- the eye patch is preferably designed so that it is curved outwards so that the inside thereof does not come into contact with the eyelashes. If the orbital cover is formed symmetrically, one and the same cover can be used for both the right and the left eye.
- the positioning device has a support unit with a support surface for the little finger and / or the ball of the thumb of the doctor treating or examining.
- Manipulations on the eye or the use of equipment or optical observation units used for this purpose are generally carried out with the thumb and the index and / or middle finger. Supporting the ball of the hand or the little finger immobilizes the doctor's hand, but allows sufficient mobility of the first-mentioned fingers for the treatment or examination.
- FIG. 1 is a view of a positioning device in a representation from the patient location without an orbital covering unit plugged in,
- Fig. 2 is a plan view of a support unit of the positioning unit shown in Figure 1 for a finger of the attending doctor.
- FIG. 3 shows a plan view of an orbital covering unit which can be plugged onto the lateral legs of the positioning device shown in FIG. 1 and which is shown attached to the left leg of the positioning device shown in FIG. 5
- Fig. 4 is a view of the orbital covering unit shown in Figure 3 in the viewing direction IV and
- FIG. 5 shows a view of a variant of the positioning device shown in FIG. 1 in a representation from the patient location.
- the positioning device 40 shown in FIG. 1 from the "patient side" for positioning a human head for eye examination and / or treatment has a forehead support and a chin support part 41 and 43, respectively.
- the forehead support part 41 is preferred designed as a flexible band.
- the chin rest part 41 is made stably from injection molding or plastic and has a recess 45 in its center for positioning the chin of the patient.
- the front bearing part 41 is on both sides at its end regions by means of two screws 46 on a rod-shaped. here, for example, U-shaped frame element part 47 is attached.
- the connecting bow 49 of the U-shaped frame element part 47 extends above the forehead support part 41 at such a distance that it comes to rest on the forehead when the patient's head is in place.
- the two legs 50a and 50b of the frame element part 47 are rod-shaped with a circular cross section.
- the chin rest part 43 is adjustable in height.
- the left end region of the chin rest part 43 in FIG. 1 carries a bushing 51 which can be displaced onto the left leg 50a of the frame element 47 in a barrel fit.
- the chin rest part 43 has a holding bush 53 designed as a guide bushing.
- the height of the holding bush 53 is significantly larger than that of the liner 51.
- a knurled nut 55 is arranged around the longitudinal axis of the right leg 50b of the frame element part 47 and the holding bush 53, but is held axially fixed on the holding bush 53.
- the right leg 50b has an external thread 56 on its lower end region, on which the knurled nut 55 can be rotated. By turning the knurled nut 55, this and thus also the chin rest part 43 can be moved up and down on the leg 50b for height adjustment.
- the free ends 57a and 57b of the legs 50a and 50b of the frame element 47 are each inserted into a free end of a further U-shaped frame element 59 in a press fit and each secured with a split pin 61a or 61b.
- the arch 62 of the frame element 59 has fastening elements 63 with which egg can be fastened, for example, to a table 65.
- a left or right handle 67a or 67b for the patient's hands is arranged on the legs 66a and 66b of the frame element 59 below the split pins 61a and 61b.
- the axes 69 of the handles 67a and 67b are aligned with one another and run horizontally. Holding the patient by the handles 67a and 67b improves the positioning and immobilization of his head in the positioning device 40.
- a support unit 71 is arranged below the attachment of the front bearing part 41 to the legs 50a and 50b. Both support units 71 are identical.
- the one shown in FIG. 2 enlarged as a separate component compared to the illustration in FIG. 1
- Support unit 71 has an opening 72 through which the relevant leg 50a or 50b engages, and a support surface 73 for one of the fingers, preferably for the little finger of the doctor treating the patient. The doctor can rest his hand by placing his finger on it and perform activities on the patient's eye with high precision.
- an orbital cover unit 24 can be manually plugged onto these without the use of tools such as screwdrivers, pliers, ...
- FIG. 5 shows a variant of a positioning unit 2 to that shown in FIG. 1.
- the eye covering unit 24 has an orbital flap 25 which can be pivoted in against the eye socket of the eye which is not to be examined or treated.
- the orbital flap 25 is curved outwards, ie away from the eye when it is inserted into the eye socket.
- the contour region 27 of the orbital flap 25 coming to lie adjacent to the nose-forehead transition of the patient is semicircular and is therefore adapted to this.
- the orbital covering unit 24 has a spacing part 29 on which the orbital flap 25 is pivotably held by a swivel joint 30.
- the distancing part 29 has at its end facing away from the orbital flap 25 an attachment part 31 for tool-free connection to the left or right leg 50a or 50b.
- the attachment part 31 has left and right jaws 33a and 33b.
- the jaws are designed to be elastically spreadable by a tolerance so that they can be plugged onto the rod-shaped legs 50a and 50b. In the plugged-on state, both jaws 33a and 33b grip around the rod jacket by a tolerance greater than half the circumference. To achieve the expandability required for the attachment, it would be sufficient if only one of the two jaws were resilient and the other was rigid. However, both are preferably designed to be elastically deformable (expandable) due to simpler production.
- the orbital covering unit 24 In order to keep the orbital covering unit 24 horizontally immovable, but pivotable on the legs 50a and 50b, they each have a circumferential groove 75 below the fastenings for the forehead contact part 41. To match this groove 75, the attachment part 31 has a web 35 running on the inside of the jaw.
- the spacer 29 is. as can be seen in particular from FIG. 2, formed in an arc shape.
- the arch is designed in such a way that the distancing part 29 engages around the cheekbones of the face when the orbital flap 25 is folded into the eye socket.
- the legs 50a and 50b are set back relative to the face when the head is introduced into the positioning device 40. The legs 50a and 50b do not hinder the doctor in his work on the eye.
- the spacing part 29 does not have to be an approximately semicircular arc.
- the swivel joint 30 can be dispensed with since the eye covering unit 24 can be swiveled about the axis of the legs 50a and 50b due to the special design of the attachment part 31. With the swivel joint 30, however, there is better coverage of the eye socket and, when folded down, an appealing image.
- the positioning device 2 shown in FIG. 5 in a view from the "patient side" as an embodiment variant of the positioning device 40 also has a front end part and a chin rest part 1 or. 3.
- the front part 1 is preferably designed as a flexible band.
- the chin rest part 1 is made stably from injection molding or plastic and has a recess 5 in its center for positioning the chin of the patient.
- the front bearing part 1 is on both sides with a rod-shaped. for example, U-shaped frame element part 7 attached.
- the connecting bend 9 of the U-shaped part 7 ⁇ runs above the forehead contact part 1 at such a distance that it comes to rest on the forehead when the patient's head is on.
- the chin rest part 3 is arranged on a stamp 10 adjustable in height.
- the ends of part 7 are firmly inserted in the end areas of a two-pronged fork part 15.
- the fork arm 16 of the fork part 15 is fastened on a base 17.
- the base 17 can be a table or part of a device.
- the stamp 10 is held in the fork handle 16 and adjustable in height via an adjusting unit 20.
- a support unit 21a and 21b is arranged in each case.
- the support units 21a and 21b are designed as a bowl arch, the arch being so large that the palm of the doctor treating it can be inserted. By inserting the ball of his hand, the doctor can immobilize his hand and perform activities on the patient's eye with high precision.
- the support units 21a and 21b are of identical design: can therefore be arranged on the legs 22a or 22b either on the right or on the left.
- Below the attachment 23a and 23b of the ends of the front abutment part 1 to the legs 22a and 22b is also the orbital covering unit 24 without the use of tools such as e.g. Screwdriver. ... can be attached manually.
- attachment part 31 and the legs 22a and 22b or 50a and 50b with a web 35 and grooves 34a and 34b for horizontal displacement protection
- other elements can also be used. If pivoting around the thigh sheath is avoided, a blind hole and a suitable nipple can be provided. The circumferential grooves can be made wider by a tolerance than the height of the jaws of the attachment part; the web 35 can then be dispensed with. It is also possible to completely dispense with the attachment part 31 and instead to make two blind holes or through holes in the legs, into or through which the two cylindrical elements at the end of the disintegration part can then be inserted.
