Definitions

  • the present invention relates to improvement applications that can be applied to any bed utilized in hospitals, medical centres and nursing homes.
  • Beds utilized in hospitals and other health care facilities are typically designed with complicated actuation mechanisms to enable movement of the various surfaces. These adjustments are necessary and common for both the patient being treated and for the physician administering the treatment, in order to achieve a comfortable and medically safe height and/or slope of the bed surface.
  • Hospital beds require side rails with standard size of either 4 or 1 1 inches, they aim to prevent the patient from falling out of the bed and are designed for patients lying on a standard mattress.
  • Some of the mattresses used to avoid pressure sores are significantly taller than the standard mattresses and the current safety rails, even when raised, are barely taller than the mattress and provide almost no protection to the patient from falling out of the bed.
  • a safety rail that can accommodate both types of mattresses is important for patient safety and peace-of-mind.
  • beds which can provide for weighing unconscious or un-ambulatory patient without any disturbance to the patient.
  • the patient's weight is a good indicator of their health, reveals if they are getting adequate nutrition, and determines the dosage of medication. While it should be relatively simple to weigh a patient lying on a bed, the multiple support points and the uneven weight distribution, makes expensive and highly sophisticated electronic correction necessary in today's beds in order to achieve even basic accuracy. An inexpensive solution for this problem would be a significant improvement.
  • Medical patient record storage is a significant issue and these records need to be secure and confidential but also readily and easily accessible to properly authorized caregivers. Hospital beds with provision of such record storage facility will help in accessing the records easily by the physician.
  • the over bed table is necessary in hospitals and nursing homes to store personal items such as laptops and reading material, and medical personnel may set wash basins, assorted medicines and bandaging materials used in treatment.
  • the over bed table is also used to serve food for the patient.
  • the conventional over bed table has a floor mounted base which occupies floor space even when the table is not in use. Additionally, when the table is moved away from the patient, it has to be searched for when needed. Therefore, it creates the need for an improved system that could reduce the floor space and with adjusting means.
  • Today's treatment includes electrically powered medical devices which get plugged in individually, creating a tangle of wires and requiring a number of plug points in the wall.
  • the present invention overcomes all the above said drawbacks and provides a hospital bed with less complex mechanism involved.
  • the present invention is a bed particularly used in hospitals to ensure safety, less space, minimal operating efforts and simple mechanism.
  • the hospital bed used in this invention has a scissor jack (also known as screw jack) mechanism aided by a mechanical spring assist to adjust the height of the bed surface.
  • the bed surface can be lowered to 300 mm to ensure patient safety and peace-of-mind during which the energy is stored in the mechanical spring by means of compression of spring. This compressed energy is utilized during the raising of the bed surface up to 800 mm with minimal effort.
  • the scissor jack used in this invention has a pair of springs placed on the screw rod. As the bed (with the patient ) is moved downwards by means of rotating the lever of the scissor jack in counter clockwise direction, the nuts move away from each other compressing the spring on to the cap of the screw rod. At the minimum position of the bed, the spring is compressed to its

  • the side rail swings out and an extension that doubles the height of the side rail by swinging out once more. This allows the side rail to be extended to achieve a greater height, thus ensuring the safety of the patient even on an elevated mattress.
  • the rail also self-locks when extended thereby ensuring the safety of the patient.
  • the safety rail is lowered, it is “doubled” up and reinforced which gives even more stability when used as a holder for the restraints.
  • Another objective of the present invention is to accommodate taller people in the bed by easily extending the length of the bed surface without discomforting, dismantling or adding any 135 components to the bed.
  • the objective of the present invention is achieved by changing the size of the bed surface through extending the leg edge of the bed.
  • the improved bed surface of the invention has a larger diameter pipe, a smaller diameter bent pipe at the leg end which slides into the larger 140 diameter pipe like a telescopic arrangement.
  • the extended surface is held in place by means of self-locking clamp pins.

  • the knee break surface or leg end of the bed surface has a length extension capability.
  • the integrated trendelenburg mechanism is controlled by means of a threaded pivot block which moves up and down.
  • This vertical motion is controlled by the gear box consisting of worm shaft and worm wheel.

Abstract

La présente invention concerne une amélioration apportée à un lit utilisé dans les hôpitaux, les centres médicaux et les maisons de soins de santé, qui prend en compte le confort du patient et du personnel soignant sans impliquer de mécanisme complexe. Le lit de l'invention comprend un mécanisme à vérin à vis unique assisté par un ressort mécanique pour ajuster la hauteur de la surface du lit. L'énergie est stockée dans le ressort pendant la compression et peut être récupérée pendant l'élévation du lit avec un effort minimal. Le mécanisme utilisé dans le lit de l'invention ne comprend ni tuyaux ni barres sous la surface des lits comme dans les lits classiques et permet ainsi aux patients de pouvoir ranger leurs effets personnels. Les améliorations apportées au lit de l'invention comprennent, entre autres, des rails latéraux extensibles pour assurer la sécurité des patients, une surface de couchage extensible pour recevoir des personnes de toute taille, un système de calcul du poids du patient sans gêne pour les patients occupant le lit, une partie pied de lit équipée d'un rangement pour des dossiers, une tablette pour lire/conserver des accessoires des patients ou des médecins et une barre d'alimentation.
