Abstract
Description
Technical Field
[0001] This utility model relates to the field of hyperbaric oxygen chamber technology, specifically a structure for a hyperbaric oxygen chamber used for electrocardiogram examination. Background Technology
[0002] A hyperbaric oxygen chamber creates a high-pressure, high-concentration oxygen environment to promote oxygen absorption in patients. This environment can improve blood supply to the brain and facilitate carbon dioxide expulsion in cases of poisoning from harmful gases, thus improving patient prognosis. However, the excessively high oxygen content and prolonged exposure in a hyperbaric oxygen chamber can easily lead to oxygen toxicity. Therefore, an electrocardiogram (ECG) is necessary before patients undergo hyperbaric oxygen therapy.
[0003] Because hyperbaric oxygen chambers are pressure vessels, there are restrictions on electrical appliances installed inside. These restrictions primarily include: AC power is prohibited, and the voltage of any electrical appliance allowed inside cannot exceed 24V. Therefore, current electrocardiogram (ECG) monitoring equipment cannot be placed inside a hyperbaric oxygen chamber. Consequently, ECG equipment is typically placed on the outside of the chamber, using a long cable harness running through it. However, this cable harness can compromise the airtight environment of the hyperbaric oxygen chamber, making it prone to leaks under high pressure. Utility Model Content
[0004] The purpose of this invention is to provide a hyperbaric oxygen chamber structure for electrocardiogram (ECG) examination, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a hyperbaric oxygen chamber structure for electrocardiogram examination, comprising a hyperbaric oxygen chamber body, a connecting hole on the chamber body of the hyperbaric oxygen chamber body, the inner wall of the connecting hole having a stepped structure, an installation sleeve inserted into one end of the connecting hole located on the inner side wall of the chamber body of the hyperbaric oxygen chamber body, a sealing rubber ring for deformation and stable fitting between the installation sleeve and the inner wall of the connecting hole, a wire harness body inserted into the inside of the installation sleeve, an installation groove on the inner wall of the installation sleeve, a compression rubber ring fixedly connected inside the installation groove, a compression rope on the outer side wall of the compression rubber ring, the compression rope being used to control the compression deformation of the compression rubber ring and to tightly connect with the wire harness body, at least a control plate on the inner wall of the installation sleeve, the control plate consisting of a guide part, a moving part and a connecting part, the control plate being used to control the traction force of the compression rope, a connecting platform fixedly connected to the upper end of the installation sleeve, a control screw for controlling the tension of the compression rope being threadedly connected to the middle of the connecting platform.
[0006] Preferably, the middle part of the extrusion rope surrounds the control extrusion rubber ring, and the free ends of both ends of the extrusion rope are staggered at the upper end of the extrusion rubber ring.
[0007] Preferably, the inner wall of the mounting sleeve is provided with a sliding groove, and an auxiliary block is fixedly connected to the side end of the moving part, and the auxiliary block and the sliding groove are slidably connected.
[0008] Preferably, the guide portion and the connecting portion are fixedly connected to both sides of the moving portion, the moving portion has an arc-shaped structure, a connecting ring is fixedly connected to the middle of the connecting portion, and the two free ends of the extrusion rope are fixedly connected to the two connecting rings respectively.
[0009] Preferably, the side end face of the guide portion has an arc-shaped structure, and the lower end of the control screw is fixedly connected to an extrusion head, the lower end of the extrusion head has an arc-shaped surface, and the side end of the extrusion head abuts against the side end of the guide portion.
[0010] Preferably, a plurality of traction ropes are fixedly connected to the inner wall of the mounting sleeve, and the top end of the traction rope is fixedly connected to the side end of the connecting rope.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: An installation sleeve is provided at the connection between the wire harness body and the hyperbaric oxygen chamber body. By rotating the control screw, the control plate is squeezed, causing the control plate and both ends of the squeezing rope to move. The squeezing rope squeezes the squeezing rubber ring, deforming it and ensuring that the inner wall of the squeezing rubber ring is tightly connected to the wire harness body. This allows for adaptation to wire harness bodies of different diameters, ensuring that the squeezing rubber ring will not undergo significant deformation leading to leakage under high pressure, thus ensuring the sealing of the hyperbaric oxygen chamber body.

[0018] To enhance understanding of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described and introduced below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, not all embodiments, and are not intended to limit the embodiments in any way. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution: a hyperbaric oxygen chamber structure for electrocardiogram examination, including a hyperbaric oxygen chamber body 1. The body 1 has a connecting hole 2, the inner wall of which has a stepped structure. An installation sleeve 3 is inserted into one end of the connecting hole 2 located on the inner wall of the body 1. A sealing rubber ring 4 for deformation and stable connection is provided between the installation sleeve 3 and the inner wall of the connecting hole 2. A wire harness body 7 is inserted into the installation sleeve 3. An installation groove is provided on the inner wall of the installation sleeve 3, and the installation groove is used for fixed connection. There is a compression rubber ring 8, and a compression rope 9 is provided on the outer wall of the compression rubber ring 8. The compression rope 9 is used to control the compression deformation of the compression rubber ring 8 and is tightly connected to the wire harness body 7. At least two control plates 10 are provided on the inner wall of the mounting sleeve 3. The control plate 10 is composed of a guide part 101, a moving part 102 and a connecting part 103. The control plate 10 is used to control the traction force on the compression rope 9. A connecting platform 12 is fixedly connected to the upper end of the mounting sleeve 3. A control screw 14 for controlling the tension of the compression rope 9 is threadedly connected to the middle of the connecting platform 12.
[0020] The middle part of the compression rope 9 surrounds the control compression rubber ring 8. The free ends of the two ends of the compression rope 9 are intersected with the upper end of the compression rubber ring 8. When the two ends of the compression rope 9 are pulled and moved, the middle of the compression rope can compress the compression rubber ring 8 and deform it, so that the inner wall of the compression rubber ring 8 and the wire harness body 7 are tightly fitted together, avoiding leakage under high pressure.
[0021] The inner wall of the mounting sleeve 3 is provided with a sliding groove. An auxiliary block 16 is fixedly connected to the side end of the moving part 102. The auxiliary block 16 and the sliding groove are slidably connected. The guide part 101 and the connecting part 103 are fixedly connected to both sides of the moving part 102. The moving part 102 has an arc-shaped structure. A connecting ring 15 is fixedly connected to the middle of the connecting part 103. The two free ends of the extrusion rope are fixedly connected to the two connecting rings 15 respectively. The side end face of the guide part 101 has an arc-shaped structure. An extrusion head 13 is fixedly connected to the lower end of the control screw 14. The lower end of the extrusion head 13 has an arc-shaped surface. The side end of the extrusion head 13 abuts against the side end of the guide part 101. By rotating the control screw 14, the control screw 14 drives the extrusion head 13 to move downward. The extrusion head 13 can extrude the guide part 101, thereby pushing the control plate 10 to move. The control plate 10 pulls the extrusion rope 9.
[0022] Multiple traction ropes 11 are fixedly connected to the inner wall of the mounting sleeve 3. The top end of the traction rope 11 is fixedly connected to the side end of the connecting rope. When the wire harness body 7 is removed, the traction rope 11 can restrict the compression rope 9 to ensure the shape of the compression rope 9, which is convenient for the subsequent reinstallation of the wire harness body 7.
[0023] The sealing rubber ring 4 has an L-shaped cross-section. A sealing protrusion 5 is fixedly connected to the side end of the sealing rubber ring 4, and a connecting protrusion 6 is fixedly connected to the side end of the mounting sleeve 3. The connecting protrusion 6 is located between the sealing protrusion 5 and the sealing rubber ring 4. When the hyperbaric oxygen chamber body 1 is in a high-pressure environment, the mounting sleeve 3 can squeeze the sealing rubber ring 4 and deform it, so that the connecting protrusion 6 and the sealing protrusion 5 fit tightly together, ensuring the sealing performance of the connection between the mounting sleeve 3 and the hyperbaric oxygen chamber body 1.
