Abstract
Description
- To make a patient feel more comfortable when he or she is lying on a sickbed, the sickbed is usually so designed that a head portion and/or a rear portion thereof can be adjusted to incline at different angles. However, since not all the patients have the same sick condition and therefore, the inclination of the sickbed at its head portion and/or rear portion is not necessarily suitable for or meeting the requirement of all patients. Thus, it is still necessary for a tender to help the patient to lie on side or in other desirable position so that the patient may feel more comfortable. And, for a bedrid patient, sometimes two tenders are required to help the patient to the toilet room. It is therefore desirable to develop a multipurpose sickbed of which the head, middle, and rear portions as well as the left and right sides can be raised or lowered, inclined or leveled, or alternately raised for air ventilation purpose through different control mechanisms.
- Document US-A-2 271 201 discloses a multipurpose sickbed. This document is silent to the mention of the head, middle and rear sections consisting of fixed and movable frame plates and boards.
- The present invention is defined by the features of claim 1.
- A primary object of the present invention is to provide a multipurpose sickbed, and more particularly to provide a sickbed of which the bed boards can be partially raised, lowered, inclined, and leveled through a number of control means. The sickbed according to the present invention is equipped with a first control mechanism which controls the axial inclination of a head section of the bed, a second control mechanism which controls the alternate raising of movable boards of the head and a middle sections of the bed, a third control mechanism which controls the axial inclination of a rear section of the bed so that a raised bed rear board forms a footrest, a fourth control mechanism which controls the leftward or rightward inclination of a left or a right side of the head, middle, rear sections of the sickbed so that the patient on the bed may lie on side, and a fifth control mechanism which controls the descent of the middle section of the bed for the positioning of a bedpan or a urinal thereat to facilitate the convenient and comfortable excretion of the patient.
- In brief, the multipurpose sickbed according to the present invention is characterized in that:
- 1. The sickbed can be partially inclined at various angles through a number of control mechanisms and therefore, it is not necessary for a tender to directly turn the patient lying on the sickbed;
- 2. The middle section of the sickbed can be lowered to accommodate a bedpan or a urinal and therefore, the patient may conveniently and comfortably excrete on the sickbed;
- 3. The sickbed has movable bed boards which can be adjustably lowered for air ventilation purpose when the patient, especially a bedrid patient, feels uncomfortable due to lying in the sickbed for a long time;
- 4. The sickbed has a rear section which can be raised with a small utmost rear part thereof downward bent again to form a footrest for the feet of patient to be comfortably supported thereon;
- 5. The bed surface can be adjustably inclined through the control mechanisms and the sickbed is therefore very practical in use; and
- 6. The change of lying position and the excreting of the patient can all be taken care through the use of control mechanisms by the tender, and a lot of efforts and manpower can be saved.

- Please refer to Figs. 1, 2, 3, 5, 6, 7, 12, 13. A sickbed according to the present invention is divided into three sections, namely, a
head section 100, amiddle section 200, and arear section 300. All of these three sections have the same bed board structure which includes a top layer, a middle layer, and a bottom layer. - The top layer of each
section left half right half left half boards movable boards right half boards movable boards - The bottom layer of the
head section 100 consists of aframe plate 140 having two laterally oppositerectangular openings 141, 141', arotary shaft 142 fixed to a top middle portion thereof between the twoopenings 141, 141' and connecting a fourth and a fifthrotary wheels 144, 144' thereon, and two threadedrods 160, 160' rotatably connected near two side edges of theframe plate 140 by means of two pairs offixing mounts 161, 161'. - The middle layer of the
head section 100 consists of twomovable frame plates 150, 150' having anopening 151, 151' therein and laterally disposed on theframe plate 140 within the tworectangular openings 141, 141' and secured to the latter by means ofhinges movable frame plates 150, 150' can be pivotly turned about thehinges -
Pads 149, 149' are provided on a top surface of theframe plate 140 at proper positions to facilitate the smooth movement of themovable frame plates 150, 150'. When themovable frame plates 150, 150' are lowered to a lowest position in theframe plate 140, themovable boards boards openings 151, 151' of themovable frame plates 150, 150' with their bottom surfaces in the plane of theframe plate 140. Themovable frame plates 150, 150' are formed with a plurality of fixingholes torsional leaf springs screws 154, 154' or by means of welding. Each pair of thetorsional leaf springs pin 157, 157' passing through pin holes 158, 158' formed at another end of thetorsional leaf springs crescent members 155, 155', 155'', 155''', 156, 156', 156'', 156''' are provided between the twomovable frame plates 150, 150' at a lower inner edge thereof. - Please refer to Figs. 1, 2, 3, 4, and 7. The sickbed of the present invention is equipped with five control mechanisms, namely, the first, the second, the third, the fourth, and the
fifth control mechanisms - The
first control mechanism 130 is used to control thehead section 100 and consists of a crank handle 130 near the rear end of the sickbed, amain shaft 131 integrally extending from the crank handle 130 and having a threadedsection 132 formed at a predetermined position thereon, an internally threadedblock 133 engaged with the threadedsection 132 and having twostoppers trapezoidal member 134 having two spaced and downward tapered legs and an axially extendedmiddle groove 1341 formed between the two legs so that thetrapezoidal member 134 is received between the twostoppers section 132 passing through themiddle groove 1341. By this arrangement, when thefirst control mechanism 130 is turned, the internally threadedblock 133 is prevented from turning along with the threadedsection 132 but moves forward or backward thereon in a linear movement and thereby drives thetrapezoidal member 134 to move upward or downward, respectively. The two legs of thetrapezoidal member 134 have two outward projectedflanges 1342, 1342' by which thetrapezoidal member 134 is stopped at a certain height without disengaging from the internally threadedblock 133 when it is moved upward by the same. Since an upper end of thetrapezoidal member 134 is fixed to theframe plate 140, when thetrapezoidal member 134 is moved upward through thefirst control mechanism 130, thehead section 100 of the sickbed is lifted to form an inclination as shown in Figs. 2 and 3. - Please refer to Figs. 1, 2, and 5. The
rear section 300 of the present invention can be inclined through thethird control mechanism 330 in the same manner as that adopted by thefirst control mechanism 130 to incline thehead section 100.
