Description

Technical Field

[0001] This utility model relates to the field of bed assistive devices, and in particular to an upper limb fixation device. Background Technology

[0002] The brachial artery is a direct continuation of the axillary artery. It runs along the medial groove of the biceps brachii muscle, accompanying the median nerve downwards. First, it crosses the nerve on the medial side of the upper arm, slightly below the middle, and then turns to the lateral side of the nerve. Deep in the cubital fossa, it divides into the radial and ulnar arteries at the level of the radial neck. During and after brachial artery puncture, the patient's arm needs to be immobilized to prevent movement and avoid affecting the puncture site. Therefore, an upper limb immobilizer is needed to fix the patient's arm.

[0003] However, existing upper limb immobilizers only have the function of supporting and fixing the arm, and cannot limit the distance between the arm and the patient's body. This can easily lead to the patient's arm coming into contact with and squeezing the body, affecting the wound. Moreover, when bandaging the patient's affected area, existing upper limb immobilizers require the restraints to be removed first, which is cumbersome and can easily cause secondary damage to the affected area. Therefore, this application provides an upper limb immobilizer to meet the needs. Utility Model Content

[0030] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0031] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0032] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0033] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0034] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides an upper limb fixation device, including a limiting support pad 1. A backing mechanism 3 is provided on one side of the limiting support pad 1, and the backing mechanism 3 is used to back against the patient's body. An adjustment mechanism 2 is provided between the limiting support pad 1 and the backing mechanism 3, and the adjustment mechanism 2 is used to adjust the distance between the limiting support pad 1 and the backing mechanism 3. A groove 4 is provided at the top of the limiting support pad 1.

[0035] The groove 4 at the top of the limiting support pad 1 can support and limit the patient's arm, thus preventing displacement during treatment and bandaging and avoiding any impact on the treatment. The abutment mechanism 3 on one side of the limiting support pad 1 can abut against the patient's side, limiting the position between the limiting support pad 1 and the patient's body. The adjustment mechanism 2 between the limiting support pad 1 and the abutment mechanism 3 can adjust the distance between the limiting support pad 1 and the abutment mechanism 3 as needed, thereby changing the distance between the limiting support pad 1 and the patient's body and preventing the patient's body and arm from moving and touching each other, which could cause secondary damage to the affected area.

[0036] like Figure 2 and Figure 3 As shown, the top of the limiting support pad 1 is fixedly connected with two sets of buckles 6. The two sets of buckles 6 are located on both sides of the support groove 4. The two sets of buckles 6 fixedly connected to the top of the limiting support pad 1 facilitate the binding of the restraint belt to restrain and limit the patient's arm.

[0037] like Figures 1 to 3 As shown, the top of the limiting pad 1 is provided with a bandaging groove 5, which extends horizontally through the support groove 4, and the depth of the bandaging groove 5 is greater than the depth of the support groove 4. The bandaging groove 5 at the top of the limiting pad 1 facilitates the placement of a bandage for bandaging, so that after the brachial artery puncture is completed, the wound can be bandaged and fixed with a bandage.

[0038] like Figure 1 As shown, the inner wall of the bracket 4 is provided with a breathable groove 7 and an antibacterial adhesive film is attached to the inner wall of the bracket 4. The breathable groove 7 provided in the inner wall of the bracket 4 avoids the situation where the patient's arm is completely attached to the inner wall of the bracket 4 after being restricted, which would cause difficulty in sweating and poor breathability, thus improving the patient's comfort.

[0039] like Figure 1 , Figure 3 and Figure 4As shown, the adjusting mechanism 2 includes a threaded rod 15 fixedly mounted on one side of the limiting support 1 via a turntable. A threaded cylinder 16 is rotatably mounted on one end of the threaded rod 15, and a connecting screw 17 is rotatably mounted on the other end of the threaded cylinder 16. The abutting mechanism 3 includes an abutting plate 18 fixedly connected to one end of the connecting screw 17. An installation hole 19 is provided inside the abutting plate 18, and a memory metal rod 20 is fixedly mounted inside the installation hole 19. By rotating the threaded cylinder 16 rotatably mounted on one end of the threaded rod 15, it is convenient to use the threaded cylinder 16. The distance between the threaded rod 15 and the connecting screw 17 is adjusted to change the distance between the limiting pad 1 and the abutment plate 18, thereby fulfilling the need to adjust the distance between the patient's arm and body. This facilitates brachial artery puncture and bandaging and improves the patient's arm positioning comfort. The memory metal rod 20, which is fixedly installed inside the mounting hole 19 of the abutment plate 18, can be bent and recovered and has elasticity, allowing the abutment plate 18 to fit different patients' bodies, thus improving the comfort when the abutment plate 18 fits the patient's body.

[0040] like Figure 1 and Figure 3 As shown, a pair of telescopic frames 14 are fixedly connected between the abutment plate 18 and one side of the limiting pad 1. The pair of telescopic frames 14 are symmetrically arranged on the same horizontal line. The pair of telescopic frames 14 fixedly connected between the abutment plate 18 and one side of the limiting pad 1 can limit the translational position of the abutment plate 18, so as to avoid the abutment plate 18 tilting to the side and affecting the adjustment of the distance between the patient's body and arm.

[0041] like Figure 2 As shown, a cavity 10 is provided on one side of the limiting pad 1. Both the cavity 10 and the groove 4 are inclined. By providing a cavity 10 on one side of the limiting pad 1, the weight of the entire limiting pad 1 and the production cost are greatly reduced.

[0042] like Figure 3 As shown, the bottom end of the limiting support pad 1 is provided with a pair of storage slots 8. The top of each of the storage slots 8 is fixedly connected to a magnetic sheet 11. A restraint strap 9 is snapped into the storage slot 8. The restraint strap 9 is made of a strap with magnetic sheets. Through the pair of storage slots 8 at the bottom end of the limiting support pad 1, the anti-slip effect of the limiting support pad 1 is improved. At the same time, the magnetic sheet 11 fixedly connected to the top of the storage slot 8 can be used to attract and store the restraint strap 9, which improves the convenience of using the whole device.

[0043] like Figure 3 As shown, the bottom end of the limiting support pad 1 has a groove 12, and a Velcro 13 is fixedly connected inside the groove 12. The Velcro 13 fixedly connected inside the groove 12 at the bottom end of the limiting support pad 1 facilitates quick fixing and positioning of the entire limiting support pad 1 in conjunction with the Velcro seat.

[0044] The working principle of the technical solution provided by this utility model is as follows: The limiting support pad 1 is fixed to the hospital bed by the Velcro 13 fixedly connected inside the groove 12 at its bottom end. The patient lies flat on one side of the backing plate 18. The arm of the patient who needs to perform brachial artery puncture is placed in the groove 4 opened at the top of the limiting support pad 1, so that the brachial artery puncture site is directly above the bandaging groove 5. The restraint strap 9 located inside the storage groove 8 is pulled out and fastened inside the buckle 6 to restrain and fix the patient's arm. Then, the bandage for bandaging is placed inside the bandaging groove 5. After the brachial artery puncture is completed, the bandage can be used to bandage the patient's affected area. During the use of the device, by rotating the connecting screw 17, the distance between the threaded rod 15 and the threaded cylinder 16 can be shortened, thereby adjusting the distance between the backing plate 18 and the limiting support pad 1 to meet the needs of adjusting the distance between the patient's arm and body.

[0045] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
