Description

TECHNICAL FIELD

[0001] The present application relates to the field of body position restraint, especially the body position restraint for field nursing. BACKGROUND

[0002] Body position restraint refers to the use of specific devices or methods to limit the body position or limb movement of a patient during medical care, to ensure the smooth progress of treatment and care, protect the safety of patients, and prevent accidents. It is a special nursing operation that needs to strictly follow relevant standards and principles, and is reasonably used on the premise of protecting the rights and interests of patients. The most common one is the fixed stretcher. It is mainly used for transporting the wounded and sick, and the body is fixed on the stretcher through specific devices or methods to avoid secondary injury caused by shaking, bumping or body position change during transportation. It is widely used in emergency scenes, transportation and hospital examination and treatment scenes, and is an important part of emergency care and transportation technology.

[0003] Under the conditions of field operations and training, personnel injuries are inevitable, so the body position restraint of the wounded also inevitably uses the stretcher, but the existing stretcher is generally simple in design and poor in universality, and cannot realize the military-civilian combination use of the stretcher. That is, no matter in what background, the stretcher can achieve the purpose of application through flexible adjustment. For example, under the conditions of field operations and training, or in earthquake rescue, the wounded generally have serious limb injuries, so they need to be restrained more comprehensively. Therefore, the traditional stretcher with stretcher cloth cannot achieve effective stability, and it is also difficult to stabilize when lifting and transferring. In this case, it is best to use a metal frame stretcher with a stable support structure instead of a stretcher cloth stretcher. And in actual rescue, the body types of the wounded are quite different. We can usually see some larger wounded lying on the stretcher, and their bodies have overflowed the stretcher, which has caused constraints to effectively restrain them.

[0004] The body position restraint brake for field nursing disclosed in the patent with the publication number CN217118763U discloses a body position restraint brake for field nursing, which comprises a support plate, handles are fixed at the four corners of the outer part of the support plate, linkage mechanisms are rotatably arranged at the left and right sides of the inner part of the support plate, a driving mechanism is fixed at the middle end of the inner part of the support plate, the driving mechanism is fixedly connected with the linkage mechanisms, displacement mechanisms are fixedly arranged on the outer walls of the linkage mechanisms, the displacement mechanisms slide through the front end of the support plate, lithium batteries are tightly arranged at the top end of the inner part of the support plate, limiting plates are fixed at the four corners of the front end of the outer wall of the support plate, and the limiting plates and the displacement mechanisms correspond to each other. The body position restraint brake for field nursing can conveniently fix and constrain the posture of a patient in a prone position. Therefore, the device not only reduces the working intensity of medical staff but also improves the treatment progress of the patient.

[0005] Although the above technical solution can constrain and fix the wounded person, it is inconvenient to adjust, cannot be applied to wounded persons of different body types, and cannot realize flexible switching between the frame stretcher and the stretcher cloth stretcher. Therefore, the body position restraint brake for field nursing is proposed. SUMMARY

Figures 1-11 Among them, the telescopic rod 3 is an existing telescopic rod that can freely extend and retract.

[0039] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0040] The width adjusting assembly is arranged on the middle lying plate 22 or the side lying plate 23 and is used for adjusting the distance between the sliding blocks 34 on both sides of the middle lying plate 22 or the side lying plate 23. A bidirectional screw rod 10 is rotatably connected in the lower sliding groove 9. Threaded sleeves of the bidirectional screw rod 10 at two ends are symmetrically provided with sliding seats 13. The sliding seats 13 are rotatably connected with the rotating plates 19. The rotating plates 19 on the same side of the left and right are jointly rotatably connected with the clamping plates 20. The lower side of the middle lying plate 22 is provided with a positioning assembly, which is used for positioning the middle lying plate 22 between the clamping plates 20 on both sides.

[0041] The thread rotation directions of the outer sides of the two ends of the bidirectional screw rod 10 are oppositely arranged. The sliding seats 13 on the front and rear sides in the lower sliding groove 9 are respectively threadedly sleeved on the outer sides of the two ends of the bidirectional screw rod 10. Each clamping plate 20 is arranged parallel to the lifting rod 1 on the respective side. The two ends of the bidirectional screw rod 10 are rotatably connected through the front and rear inner walls of the lower sliding groove 9, extend to the front and rear outer sides of the lifting rod 1, and are connected with handles 11 at the extending ends.

[0042] In this way, the bidirectional screw rod 10 can be driven to rotate by rotating the handle 11. When the bidirectional screw rod 10 rotates, the sliding seats 13 threadedly sleeved at the two ends can be synchronously driven to slide in the lower sliding groove 9 to approach or move away from each other. When the sliding seats 13 approach each other, the clamping plates 20 on both sides are driven by the rotating plate 19 to slide to approach each other in the parallel state. When the sliding seats 13 move away from each other, the clamping plates 20 on both sides slide to move away from each other in the parallel state.

[0043] Mounting holes 36 are further arranged on the upper end surfaces of the lifting rods 1 on the front and rear sides. A stretcher cloth and a binding net are jointly clamped in each mounting hole 36. The lifting rods 1 on both sides are connected with expansion seats 37 at the two ends away from each other. A protective seat 38 for limiting the head of the wounded person or a protective plate 40 for supporting the feet of the wounded person is bolted on the expansion seat 37. A soft bag 39 is further covered on the protective seat 38. The binding net is made of a material with elasticity. The protective seat 38 can improve the fixation and protection of the head of the wounded person when the head of the wounded person is injured. The protective plate 40 can support the feet of the wounded person when the wounded person is transferred in a complex environment, so as to avoid the wounded person from sliding off the middle lying plate 22 and the side lying plate 23 between the lifting rods 1 on both sides when the wounded person is transferred in an upright posture.

[0044] So that in the specific use, when the middle lying plate 22 and the side lying plate 23 are not arranged between the two side lifting rods 1, the four corners of the stretcher cloth can be respectively installed in the installation holes 36 for fixation, so that the structure with the stretcher cloth support is formed between the two side lifting rods 1, so that some slightly injured wounded can be restrained, and the binding net can also be continuously installed in the installation hole 36 with the stretcher cloth, that is, the four corners of the binding net are also installed in the installation hole 36, so that when the wounded lies on the stretcher cloth, a stable layer of binding net can be covered above the wounded in the necessary state to achieve stable restraint of the wounded, and in the case of using the stretcher cloth, the stretcher cloth can adopt thick or air bag materials to avoid the discomfort of the wounded caused by the components between the two side lifting rods 1, and the selection of the stretcher cloth is a mature technical means, and the personnel in the field can reasonably select according to the specific use;

[0045] When the middle lying plate 22 and the side lying plate 23 are arranged between the two side lifting rods 1, the binding net can also be installed between the installation holes 36 to stably restrain the wounded on the middle lying plate 22 and the side lying plate 23;
