Description

Technical Field

[0001] The utility model belongs to the technical field of pillow structures for clinical nursing, in particular to a multifunctional fixed medical headrest for comatose patients. Background Art

[0002] In departments such as the ICU where critically ill patients gather and there is a lack of care due to busy medical staff and sterile requirements, patients who are unconscious or have no independent consciousness often experience head loss and shaking when they wake up, which makes the patients uncomfortable and is not conducive to their recovery of consciousness.

[0003] Patent CN221356921U provides a CT positioning aid with a fixed headrest. This headrest has a fixed shape and lacks wide adaptability, making it difficult to adapt to various patient head sizes. CN221718377U provides a car fixed headrest that has high fixation but is not suitable for clinical scenarios. Due to its small groove, it does not provide a fixed position for unconscious patients. CN221513156U provides a headrest-type suspended anesthesia device for clinical use by anesthesiologists. This device has a small groove and lacks a head-flipping function. It puts a lot of pressure on the back of the head, making it unsuitable for long-term use by patients and is also expensive.

[0004] In summary, the currently available nursing headrests cannot meet the patient's requirements for head fixation, head rotation, versatility and comfort. There is currently a lack of multifunctional fixed headrests designed and manufactured specifically for clinical comatose patients. Relevant products are urgently needed to provide head fixation and intelligent care for patients who are unable to support their heads independently. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention provides a multifunctional fixed medical headrest for comatose patients, which can effectively fix and turn the head of clinically comatose patients. The technical solution of the present invention is as follows:

[0006] A multifunctional fixed medical headrest for comatose patients comprises a headrest base, a left vertical column, a right vertical column, and a middle groove. The left vertical column, the right vertical column, and the middle groove are sequentially arranged on the headrest base. The left vertical column and the right vertical column are fixedly arranged on the left and right sides of the headrest base, respectively. The middle groove comprises a left half groove and a right half groove that intersect each other. The upper surface of the contact position between the two is an arc-shaped depression, forming a groove for placing the back of the patient's head; a notch is provided on the left vertical column for the left half groove to pass through, and a notch is provided on the right vertical column for the right half groove to pass through. The nursing headrest provided by the utility model is similar to a concave pillow. The left vertical column and the left and right vertical columns play a protective and pushing role, and the middle groove plays a supporting role. The slope design of the middle groove can effectively support the patient's cervical spine and prevent the cervical spine from being suspended in the air.

[0007] Preferably, the headrest base has upward-facing sides, with the left and right half grooves connected to the sides of the headrest base via central screws. Rotating the central screws adjusts the position of the left and right half grooves, thereby adjusting their relative distance to accommodate patients with different head circumferences. The width of the central groove is manually adjusted by the medical staff based on the patient's head size, and both sides are adjustable.

[0008] In the embodiment of the present invention, the middle groove is 20-25 cm long, the concave arc is gentle, and the maximum depth is 5 cm.

[0009] Preferably, the multifunctional fixed medical headrest for comatose patients further includes two transverse thrust members, one disposed on the left and one on the right vertical bars. The transverse thrust members are positioned above the notches through which the left and right half-slots pass, and include a thrust block and a thrust screw. The thrust screws extend through the left and right vertical bars, respectively, and are connected at their inner ends to the thrust blocks, driving the thrust blocks to move laterally. The left and right vertical bars are each provided with a cavity at their inner ends for accommodating the thrust blocks, with the cavity acting as a guide rail for the movement of the thrust blocks.

[0010] Preferably, the multifunctional fixed medical headrest for comatose patients also includes a neck support block, which is arranged on the headrest base along the left vertical section, the right vertical section, and the center groove. The neck support block has a curved convex side and is filled with silicone blocks or cotton wool. Together with the center groove, it supports the curve of the head, shoulders, and neck, conforming to ergonomics, preventing the cervical spine from hanging in the air and reducing cervical pressure.

[0011] Preferably, the multifunctional fixed medical headrest for comatose patients further includes a longitudinal pusher, which is disposed between the central groove and the neck support block to assist the transverse pusher in achieving head rotation. The longitudinal pushers are two symmetrically arranged members, and further preferably, a multi-layer airbag structure is employed, with each longitudinal pusher comprising a plurality of airbags connected in series. The airbags are connected to an external air pump via an air tube, and the longitudinal pusher function is achieved by adjusting the inflation and deflation of each airbag separately.

[0012] As a further improvement, the pushing screw of the horizontal pushing member is an electric screw, the airbag of the longitudinal pushing member is connected to an electric air pump, the electric screw and the electric air pump are respectively connected to a single-chip microcomputer, and the single-chip microcomputer controls the bilateral pushing distance and pushing frequency by setting parameters, thereby achieving the effect of intelligently helping unconscious patients to turn their heads.

[0013] Preferably, the middle groove is supported by silicone, and the silicone is covered with latex pressure-relieving material. The left and right vertical parts are filled with high-rebound materials such as sponge and latex to help relieve the force generated during the pushing process to improve comfort.

[0014] As an alternative, the multifunctional fixed medical headrest for comatose patients also includes a headrest cover, which is placed on the periphery of the headrest seat, left vertical, right vertical, and middle groove. A silicone pad or filling cotton is placed in the space between the headrest cover and the headrest seat, left vertical, right vertical, and middle groove as a filling layer, which serves to avoid hard contact and ensure breathability.

The left vertical 2, the right vertical 3, and the middle groove 4 are sequentially arranged on the headrest seat 1, the headrest cover 5 is sleeved on the left vertical 2, the right vertical 3, and the outside of the middle groove 4, and the neck supporting block 6 is arranged on the headrest seat 1 along the left vertical 2, the right vertical 3, and the middle groove 4; the left vertical 2 and the right vertical 3 are respectively fixed on the left and right sides of the headrest seat 1, and the headrest seat 1 is provided with upward side edges 101 on both sides, as shown Figures 1 to 4 As shown, the middle groove 4 includes a left half groove 401 and a right half groove 402. The left half groove 401 and the right half groove 402 intersect with each other, and the upper surface of the contact position between the two is an arc-shaped depression to form a groove, which is the place for the back of the patient's head to be placed; a notch is set on the left vertical 2 for the left half groove 401 to pass through, and a notch is set on the right vertical 3 for the right half groove 402 to pass through. The left half groove 401 and the right half groove 402 are respectively connected to the two side edges 101 of the headrest seat 1 through the middle groove screw 102. Rotating the middle groove screw 102 can adjust the positions of the left half groove 401 and the right half groove 402 respectively, thereby adjusting the relative distance between the two to accommodate patients with different head circumferences.

[0036] As a preferred embodiment, the middle groove 4 is 20-25 cm long, has a gentle arc shape, and a maximum depth of 5 cm. The middle groove has a sloped design that conforms to the patient's cervical spine morphology, which can effectively reduce the patient's neck from feeling suspended in the air.

[0037] The transverse thrust member 7 comprises two components, one on each of the left and right vertical members 2 and 3. Above the notches through which the left and right half-slots pass, the components include a thrust block 701 and a thrust screw 702. The thrust screw 702 passes through the left and right vertical members 2 and 3, its inner end connected to the thrust block 701, driving the thrust block 701 in transverse motion. The inner ends of the left and right vertical members 2 and 3 each contain a cavity 703 for accommodating the thrust block 701, which acts as a guide for its movement.

[0038] The longitudinal pushing member 8 is disposed between the middle groove 4 and the neck support block 6. When the patient needs to turn his head in the supine position, the longitudinal pushing member 8 pushes the patient's mandibular angle and temporomandibular position unilaterally, assisting the transverse pushing member 7 in turning the patient's head. The longitudinal pushing members 8 are two symmetrically arranged members, which can be a screw pushing structure. As a further optimization, this embodiment adopts a multi-layer airbag structure. Each longitudinal pushing member 8 includes several airbags 801 connected in series. The airbags are connected to an external air pump via an air tube 802. The longitudinal pushing function is achieved by adjusting the inflation and deflation of each airbag separately. The shape and number of layers of the airbags are not limited to those shown in the figure.

[0039] As a further improvement, the pushing screw 702 of the horizontal pushing member 7 is an electric screw, the air bag of the longitudinal pushing member 8 is connected to the electric air pump, the electric screw and the electric air pump are respectively connected to the single-chip microcomputer, and the single-chip microcomputer controls the bilateral pushing distance and pushing frequency by setting parameters, so as to achieve the effect of intelligently helping unconscious patients to turn their heads.

[0040] Neck support block 6 Figure 5 As shown, it is an arc-shaped protrusion filled with silicone blocks or cotton wool, and cooperates with the middle groove to support the curve of the head, shoulders and neck. It is ergonomic, avoids the cervical spine from hanging in the air, and relieves the pressure on the cervical spine.

[0041] In one embodiment, the headrest seat 1, left vertical 2, right vertical 3, and middle groove 4 are all made of hard materials, including hard plastic, etc. The headrest cover 5 is put on the outer periphery of the headrest seat 1, left vertical 2, right vertical 3, and middle groove 4, and a silicone pad or filling cotton is placed in the space between the headrest cover 5 and the headrest seat 1, left vertical 2, right vertical 3, and middle groove 4, which is the filling layer 501, which avoids hard contact and ensures breathability.

[0042] In another embodiment, the middle groove 4 is supported by silicone, and the silicone is covered with latex pressure-relieving material. The left and right vertical parts are filled with high-rebound materials such as sponge and latex to help relieve the force generated during the pushing process to improve comfort.

[0043] During use, the distance between the left half groove 401 and the right half groove 402 is adjusted by the middle groove screw 102 to accommodate patients with different head circumferences. When the patient lies on his back with his face upward and needs to turn his head over, the unilateral horizontal pushing member 7 pushes one side of the patient's head, and at the same time, the pneumatic longitudinal pushing member airbag on the same side is inflated to assist in turning over and relieve pressure on the back of the head.

[0044] This product not only effectively fixes the patient's head but also helps the patient to turn his head by pushing it up, relieving the pressure of long-term compression on the back of the head and improving the patient's comfort.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations.
