Description

Technical Field

[0001] This utility model relates to the field of respirators for confined space operations, and specifically to a wearable support for a positive pressure respirator that is easy to wear. Background Technology

[0002] The hazardous chemicals industry involves scenarios requiring the use of positive pressure breathing apparatus (PPBs) such as confined space operations, hazardous material leak emergency response, and personnel rescue. Female employees and older workers often find PPBs inconvenient to wear due to their limited strength, and the time required to wear them is excessive. The speed at which PPBs are donned directly impacts the efficiency of emergency rescue operations.

[0003] Chinese Patent CN222738390U discloses a positive-pressure air respirator wearable device, including a back panel, a ring-shaped gripper, a back support pad, and a waist belt rotating assembly. The ring-shaped gripper and back support pad are fixed to the front and rear sides of the back panel, respectively. The waist belt rotating assembly is hinged to the left and right sides of the back panel, and connected to a buckle via a waist belt. This invention uses a first adjustment positioning hole, a ring-shaped gripper, a limiting strap, and a buckle to secure air cylinders of different sizes, solving the problem of poor stability caused by cylinder swaying. Simultaneously, the design employs a double-sided back support pad conforming to the curve of the human back, combined with flexible shock-absorbing balls and a second adjustment positioning hole, to solve the problem of compression and impact on the back caused by the positive-pressure air respirator, while also accommodating users of different heights, effectively reducing the physical exertion of rescue personnel and meeting their needs.

[0004] While the above solution can solve the problem of wearing a formal ventilator, it requires repeated manual operation, which is time-consuming and labor-intensive.

[0005] This invention designs a support frame to improve the speed of donning a positive pressure respirator. The frame is fixed to the wall surface with screws, and the positive pressure respirator is placed on the frame when not in use. In case of an emergency, the worker can simply lift their gloves to put on the positive pressure respirator, making it convenient to use and improving the donning speed. Utility Model Content

[0107] Example 13

[0108] Based on the above embodiments, in this embodiment, the fixing mechanism includes a support back plate 1 and a buckle plate 7.

[0122] Preferably, in this embodiment, the step 10 is formed by the recess of the corresponding part of the upper part of the buckle plate 7 near the support back plate 1.

[0123] Based on the above scheme, initially, under the action of the damper 6, the buckle 7 moves upward, causing the step 10 to push against the plate 11; when wearing, due to the gravity of the positive pressure respirator cylinder, the buckle 7 moves downward a certain distance.

[0124] In addition, the aforementioned damper 6 allows the entire device to be used by workers of different heights.

[0125] Example 16

[0126] Based on any one of Embodiments 13 to 15, in this embodiment, a plurality of pre-drilled card holders 5 are fixedly installed on the support back plate 1 at even intervals from top to bottom.

[0130] During use, the support backplate 1 is fixed to the wall, and then the support hoop 2 and multiple bottle hoop 3 are fixedly installed on the buckle plate 7 respectively; the operator faces away from the snap-fit ​​assembly and uses the support hoop 2 and multiple bottle hoop 3 to snap the positive pressure breathing apparatus cylinder, while removing the shoulder strap and hanging the shoulder strap on the two shoulder strap rods 4, thus realizing the storage of the positive pressure breathing apparatus cylinder.

[0131] When it is necessary to use the positive pressure breathing apparatus cylinder, the operator can turn away from the positive pressure breathing apparatus cylinder, remove the shoulder straps from the two shoulder strap rods 4 and put the straps on the shoulder. Then the operator pulls the positive pressure breathing apparatus cylinder outward from the support hoop 2 and multiple cylinder hoops. Finally, the operator locks the shoulder strap buckle on the breathing apparatus, puts on the mask, and the dressing process is complete.

[0132] The technical solution of this utility model consists of four parts:

[0133] The first is the bracket back plate, whose main function is to install and fix the bracket on the wall surface.

[0134] Secondly, the lower end of the gas cylinder is narrowed for support, preventing the positive pressure respirator from sliding down when installed on the bracket.

[0135] Third, the elastic semi-circular fixing cylinder clamp makes the positive pressure respirator more secure during installation, and at the same time, the positive pressure respirator cylinder can be pulled out without too much reverse force.

[0136] Fourth, a flexible shoulder strap support frame is used to attach the two shoulder straps of the positive pressure respirator.

[0137] This invention provides a wearable support for a positive pressure respirator that is easy to wear. The main purpose of this support is to improve the wearing speed of the positive pressure respirator, thereby improving the efficiency of disaster relief.

Through precise calculation and multiple adjustments of the damping coefficient, the bracket can meet the needs of people of different heights. This design improves the smoothness of the wearing process, effectively reduces the wearing time, and also improves the applicability of the bracket.

[0140] In addressing key or common technical challenges, traditional respirator donning methods are often cumbersome due to the lack of suitable supports, especially in emergencies where this inconvenience can lead to delays in rescue efforts. The support design of this invention, however, optimizes the donning process, making respirator donning simple and quick, significantly improving rescue efficiency.

[0141] In terms of key technical specifications, this support design boasts high adaptability and stability. Extensive testing has verified that the support can accommodate individuals of varying heights and maintain stable support during use, ensuring proper respirator wearing and effective protection. Its unique damping design contributes to its excellent adaptability, while its ease of use allows for widespread market adoption.

[0142] There are few similar products on the market. Traditional respirators are often stored in boxes, which cannot meet the needs of different users and the wearing process is cumbersome. The bracket of this invention adopts a damping design, which not only adapts to people of different heights but also greatly simplifies the wearing process and improves wearing speed. Furthermore, the bracket has been optimized in terms of material selection and structural design, resulting in excellent performance in terms of service life and durability.

[0143] The wearable positive pressure respirator support provided by this invention has the following advantages:

[0144] Firstly, in terms of cost reduction and efficiency improvement, we can improve work efficiency by optimizing the donning process and reducing donning time, enabling staff to get into work mode more quickly, thereby improving work efficiency. Secondly, we can reduce training costs by designing a donning speed bracket that makes the use of the respirator more intuitive and convenient, reducing the skill requirements for operators and reducing training time and costs.

[0145] Secondly, in terms of performance improvement, the precise design enhances the accuracy of wearing the air respirator, ensuring the accuracy and stability of the respirator wearing, reducing collision injuries caused by insufficient or excessive arm extension when wearing it backwards, and improving the safety and reliability of wearing it.

[0146] Third, increase the added value of the main business and enhance the brand image. As an innovative achievement, the wearable speed bracket can enhance the company's emergency technology strength and innovation capabilities, and strengthen the brand influence of the main business.

[0147] The bracket provided by this utility model has the following market competitiveness:

However, with increasing demands for operational efficiency and safety, traditional methods of donning PPBs are no longer sufficient to meet the application requirements. Therefore, innovative solutions for improving the donning speed of PPBs have significant market potential.

[0150] Several similar wearable assistive devices or technologies already exist on the market, but most suffer from shortcomings in terms of wearing speed and stability. Therefore, this innovative solution possesses a competitive advantage in performance and is expected to stand out in applications.
