Description

[0001] Patient Restraint in Surgical Beds

[0002] OBJECT AND FIELD OF THE INVENTION

[0003] The present invention belongs to the technical field of mechanics, particularly to the field of medical devices. Specifically, it pertains to the field of devices and accessories used on surgical tables or stretchers for patient immobilization.

[0004] BACKGROUND OF THE INVENTION

[0005] In the field of medicine, especially surgery and nursing, a number of body positions are used for the treatment and management of patients. One of these essential positions is the Trendelenburg position, which is used in a variety of clinical contexts and situations. The Trendelenburg position involves the patient lying on their back on a bed or stretcher that is tilted with the feet higher than the head, generally at an angle of around 15 to 30 degrees. This particular position has several medical uses, especially in situations where the patient's circulation needs to be improved.

[0006] In surgery, the Trendelenburg position is commonly used during abdominal and pelvic surgeries, such as laparoscopic gynecological and urological surgery. This position allows for better visualization and access to the pelvic organs by allowing the abdominal viscera to move toward the thorax due to gravity. Fixators or immobilizers are used to adopt and maintain this position.

[0007] Currently known shoulder fixators are protected bars that rigidly hold the patient's shoulders, which frequently causes compression injuries. There are also leg fixators that use tape or adhesive tape for fixation, or knotted sheets to prevent the patient from slipping or moving during surgery.

[0008] Currently, the Trendelenburg position is adopted on medical staff work tables, whether on a bed, stretcher, or examination table. Each position allows care staff to perform their work more comfortably. On any work table, it is essential that patients be comfortable and not endanger their safety and health. For this reason, several methods and devices have been developed that allow the patient to be positioned and immobilized on the inclined work table. For proper handling by medical staff, it is essential that the patient does not slide on the work table.

[0009] Currently, there are several devices used for this purpose, which immobilize the patient to prevent them from slipping. Among the simplest are textile straps that can be found commercially and are known as "bed restraint straps" or "safety belts for elderly patients" or "cotton shoulder harnesses" or "fall-arrest vests" or "hospital / home restraint bands." These restraint devices are specially designed to secure the patient's shoulder to the bed or wheelchair, passing through both shoulders and around the hip. However, these devices do not attach firmly to the stretcher to support the patient's weight and also cause discomfort to the patient since they only use two straps to support the entire weight. Over time, they cause discomfort and injury.These devices do not have supports with a safety harness from the shoulders to two universal side bases that attach to the operating table rail, which also have side straps with safety belts for adjustment and pins for closing and securing.

[0010] In some background of the prior art, we can find document US9149406B2, called "TRENDELENBURG PATIENT RESTRAINT FOR OPERATING TABLES" describes a patient positioning device for restricting movement of a body lying on the upper surface of a table and includes a rigid support frame extending transversely over the upper surface of the table. A cervico-thoracic notch is securely fastened to the upper support surface of the support frame, through a repositionable fastener, thereby inhibiting movement of the cervico-thoracic notch along the longitudinal axis of the table. The repositionable fastener comprises a clamping force per unit area that is sufficient to support the weight of the body on the table when it is in an inclined position with respect to the floor surface.However, this device does not have supports with a safety harness from the shoulders to two universal side bases that attach to the operating table rail, which also have side straps with safety belts for adjustment and pins for closing and securing.

[0011] For its part, document US20020157186A1, entitled “HIP BRACES” is an apparatus for securing a patient in a Trendelenburg position consisting of placing a patient on a patient support surface that is tiltable and includes a head end, a foot end, and opposite sides extending between the head end and the foot end, and coupling an upper part of the patient's hips on both sides with padded braces configured to engage the upper part of the patient's hips and prevent the patient from sliding towards the head end of the tiltable patient support surface when tilted in the Trendelenburg position. This device combines support in an area of ​​each shoulder and at the hips.However, this device also lacks supports with a safety harness extending from the shoulders to two universal side bases that attach to the operating table rail. These also have side straps with safety belts for adjustment and pins for locking and securing.

[0012] Likewise, document US20130312189A1 , entitled “POSITIONING DEVICE FOR USE IN SURGICAL PROCEDURES” consists of a device for positioning a patient in a selected body position, such as Trendelenburg or flexed position, on an operating table. The device includes a board, shoulder supports removably coupled to and extending substantially perpendicularly from the board, and a cushioning mat positioned to rest between the patient and the board and the shoulder supports when the patient is positioned on the device. A locking mechanism removably couples the shoulder supports to the board to allow the cushioning mat to lie flat when the shoulder supports are uncoupled from the board and thereby provide selective access to the patient's neck and shoulders when the patient is positioned on the device.However, this device also lacks supports with a safety harness extending from the shoulders to two universal side bases that attach to the operating table rail. These also have side straps with safety belts for adjustment and pins for locking and securing.

[0013] Also, US8601623B1 , referred to as “OPERATING TABLE PATIENT POSITIONER AND METHOD” is a patient positioner for maintaining the position of a patient during a medical procedure including a body anchoring portion positionable on top of an operating table, chest straps, support base straps, upper arm straps, wrist straps, a substrate support substantially concentrically disposed about and fixedly affixed to the body, and anchoring portion. In use, the body anchoring portion is positioned beneath a patient's torso with a substrate backing portion draped over each of the patient's arms while chest straps are positioned over the patient's shoulders and crisscross over the patient's chest and secured at an opposite side.The upper arm and wrist straps are brought out from under the patient's torso and wrapped over the patient's arms. The support base straps are routed through a break in the operating table and placed around the support base, securing each other to prevent the patient from slipping into the Trendelenburg position. However, this device is so complex to install that it is not feasible for all types of patients. It also lacks supports with a safety harness from the shoulders to two universal side bases that attach to the operating table rail, which also have side straps with safety belts for adjustment and pins for closing and securing.

[0014] Then, we have document US7412739B2, entitled “PATIENT SUPPORT APPARATUS WITH REMOVABLE FOOT SECTION” consists of a patient support apparatus including a patient support having a first patient support platform, a removable section having a second patient support platform, the removable section is configured to move to a first position in which the removable section is coupled to the patient support, a second position in which the removable section is adjacent to but spaced apart from the first position and a third position spaced apart from the patient support. A handle support mechanism is mounted to one of the patient supports and the removable section. A handle is movably mounted to the handle support mechanism and is supported thereby for movement between a first handle position and a second handle position.The handle support mechanism is configured to facilitate movement of the handle from the first handle position to the second handle position only when the removable section is oriented in and between the first and second positions. However, this document also does not disclose a device that has supports with a safety harness from the shoulders to two universal side bases that attach to the operating table rail, which also have side straps with safety belts for adjustment and pins for locking and securing.

[0015] All shoulder fixators disclosed in the prior art frequently cause pulmonary compression injuries; the disclosed devices do not evenly distribute the patient's weight from their shoulders and do not provide a firm, non-slip grip.

[0016] TECHNICAL PROBLEM TO BE SOLVED

[0017] The objective of the present invention is to develop a device that supports the patient in the forced Trendelenburg position, without the risk of sliding towards the head of the table and without causing damage by distributing the pressure to various points of the shoulder, contrary to known fixators that concentrate the patient's weight on a single point.

[0042] Referring in more detail to the drawings, as shown in Figure 1 through Figure 10, a Surgical Bed Patient Restraint Device (10) is described and it is to be expressly understood that this exemplary embodiment is provided for descriptive purposes only and is not intended to unduly limit the scope of the present inventive concept. Other embodiments and variations of the present invention entitled Surgical Bed Patient Restraint Device (10) are contemplated within the present inventive concept as set forth in the claims herein.

[0043] The Patient Fixator for Surgical Beds (10) is made up of a safety harness (20) and a pair of side straps (30) that are joined to the safety harness (20) by means of a tongue and groove joining system. In figure 1 it can be seen how the pair of side straps (30) are connected to the safety harness by means of the tongue and groove joining system; while in figure 2 it can be seen how the side straps are separated from the safety harness because the tongue and groove joining system is disconnected and released.

[0044] The Patient Fixator for Surgical Beds (10) is a device that allows the patient to be fixed and immobilized with the Safety Harness (20) from the shoulders to the sides, by means of 2 lateral straps (30) that are attached to the rail of the operating table, where the Safety Harness (20) can adjust its length according to the requirements. By means of this Patient Fixator for Surgical Beds (10) compression of the supraclavicular nerve plexuses is avoided and it helps to distribute the patient's weight with support pads (24) from their shoulders to the lateral straps (30).

[0045] Each of the side straps (30) are belts, tapes or straps made of a flexible and highly resistant material, which have, at one end, an oppressor (32) and at the other end a female clasp (31). The oppressor is the element that has the function of holding the Patient Fixator in Surgical Beds (10) in the bed or operating table. The oppressor (32) allows to hold or press a side of the bed, for example, the side rail, in a strong way and without risk of it coming loose or moving during the surgical intervention process. The oppressor (32) can be any element that allows fastening to the sides of an operating table, for example, a hook, a magnet, a clamp, a hook, rope or strap, preferably, the oppressor (32) is a clamp with a tourniquet, see figures 6 and 7.

[0046] Figure 8 shows how the side strap (30) can be placed on one side of the operating bed or stretcher, the oppressor (32) is placed in such a way that it presses an element of the operating table, preferably, it is placed on the rail on each side of the operating table.

[0047] In surgical procedures, the forced Trendelenburg position involves tilting the operating table or bed so that the patient's head and shoulders are at the lowest position, while the patient's feet are on the highest part of the operating table. The side straps should be positioned and secured to the operating table, preferably on the side of the bed opposite the head and shoulders, i.e., on the highest part of the operating table.

[0048] The Safety Harness (20) consists of a longitudinal element with 2 parallel straps in its central part, which are joined in a Strap Union (28) to be a single strap at each of its ends; the ends where it becomes a single rope are called Tension Strap (21); in the central part where there are a pair of parallel straps are called Backrest Straps (26).

[0049] At each end of the safety harness (20) there is a male clasp (25) that has the function of coupling with the female clasp (31), this part is what is identified as a tongue and groove joining system, where the male and female connector can be interchangeably in the Safety harness (20) and in the side strap (30), as long as the coupling or fastening between both is allowed. Likewise, the tongue and groove joining system can be made up of any element that allows the fastening between the Safety harness (20) and the side strap (30), for example, hooks, magnets, clamps, a grappling hook, ropes or straps, preferably, the tongue and groove joining system consists of a seat belt, like those used in cars, with a male clasp (25) and a female clasp (31).

[0050] As part of the same male clasp (25) of the safety harness (20) there is a strap adjuster (22), which consists of a buckle that allows the strap of the tension strap (21) to be moved and its function is to adjust the length of the Patient Fixator in Surgical Beds (10) which, according to the needs of the patient, the tension strap (21) must be moved to make the Patient Fixator in Surgical Beds (10) shorter or longer.

[0051] The Backrest Straps (26) of the Safety Harness (20) consist of a pair of parallel straps that have the function of maintaining contact and support with the shoulders and part of the neck and back of the patient to hold him / her. The Backrest Straps have 2 pairs of support pads (24) that wrap around them, each pair of pads is separated by a central section delimited by the Backrest Adjusters (27). The support pads (24) can be adjusted so that their separation is greater or lesser according to the needs of the patient, see figures 3, 4 and 5.

[0052] The support pads (24) are placed on and around the shoulders and their function is to distribute the patient's weight over the entire contact surface, preventing the patient's weight from concentrating on a single point and thus avoiding injuries to the patient, see figures 9 and 10.

[0053] For its part, in the central section of Backrest Straps (26), the Backrest Adjusters (27) keep the pair of straps together, which will pass through the back of the patient, preferably between the nape of the neck and back, see figures 9 and 10. The best method of using the Patient Fixator in Surgical Beds (10) consists of first placing the side straps (30), each one on one side of the operating table. Then the safety harness (20) is placed, passing the Backrest Straps (26) through the nape of the neck and positioning the support pads (24) on and around the shoulders. Subsequently, the tongue and groove joining system is fastened and the tension straps (21) are passed through to tighten it and hold the patient.Finally, the operating table is tilted to the forced Trendelenburg position and as it tilts, the tension straps (21) are moved in the Strap Regulator (23) to achieve the required tension, likewise the support pads (24) are adjusted for better patient comfort.
