Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a portable micro-pressure oxygen chamber. Background Technology

[0002] An oxygen chamber is a multi-functional manned pressure chamber used for both medical air and oxygen pressurization, and also for hyperbaric oxygen therapy. Currently, there are two types: rigid and flexible. Rigid oxygen chambers are typically deployed in hospitals for comprehensive patient treatment, while flexible oxygen chambers, being smaller and more portable, are usually used in military or home settings. Current flexible oxygen chambers generally consist of a support frame, a chamber body, and a pressure regulation system. Because the chamber body is made of flexible material, it requires support from the support frame before use to facilitate patient entry. After the patient enters, the chamber is sealed and inflated for oxygen therapy. However, during use, the support frame, composed of multiple support rods, requires manual assembly by staff before being placed into the chamber for support. This process is cumbersome, and the numerous support components make them prone to loss, affecting the device's usability. Therefore, there is an urgent need for an oxygen chamber that can be easily deployed and supported to meet these needs. Summary of the Invention

[0003] The present invention aims to provide a portable micro-pressure oxygen chamber to solve the problems of current oxygen chambers, which require manual assembly of the support frame, have many parts, are inconvenient to carry, and are easy to lose.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A portable micro-pressure oxygen chamber includes a chamber body and a support frame for supporting the chamber body. The support frame has several connecting rings connected to corresponding connecting parts on the surface of the chamber body. The support frame includes symmetrically arranged main rods, secondary rods, side rods, and storage rods. Storage rods are slidably installed within the main rods, secondary rods, and side rods. Positioning components are installed within the storage rods to limit their position. Each storage rod includes a telescopic rod and a crossbar rotatably connected to the end of the telescopic rod. The ends of two opposing sets of crossbars are connected to a connecting rod. A locking component is installed at the connection point between the crossbar and the connecting rod to limit the rotation of the crossbar relative to the connecting rod. The main rod is inverted T-shaped, with its bottom ends rotatably connected to two sets of secondary rods. The bottom of the main rod, along with the secondary rods and storage rods, forms a closed ring to support the bottom edge of the chamber body. The bottom ends of the storage rods within the main rod pass through grooves on both sides and connect to two sets of side rods. The main rod and the two sets of side rods form a three-pronged shape, which, together with the storage rods, supports the top of the chamber body.

[0006] Furthermore, the positioning component includes a positioning pin that slides through the telescopic rod and a positioning spring that pushes the positioning pin to move. The end edge of the positioning pin is rounded and located in the positioning hole. Corresponding positioning holes are opened on the main rod, the auxiliary rod and the side rod.

[0007] Furthermore, the locking assembly includes a pin that slides through the end of the crossbar and a compression spring that pushes the pin to move. The end of the pin passes through a hole at the end of the connecting rod. The connecting rod contains a pull rod and a return spring that limits the position of the pull rod. The bottom end of the pull rod is provided with a pressing plate. The side of the pressing plate is inclined and contacts the end of the pin. The top of the pull rod protrudes out of the connecting rod.

[0008] Furthermore, a handle is provided on the connecting rod, and a horizontal plate is provided at the top of the pull rod, with the horizontal plate located directly below the handle.

[0009] Furthermore, a limiting groove is provided at the bottom of the main rod, and an insert block is slidably disposed in the limiting groove. The end of the insert block passes through a slot on the secondary rod to limit the rotation of the secondary rod.

[0010] Furthermore, a support rod is hinged to the secondary rod, and the top of the support rod is hooked onto the side rod. Both the side rod and the support rod are equipped with magnetic plates, and the two sets of magnetic plates are positioned correspondingly.

[0011] Furthermore, fixing blocks are provided on both sides of the main pole, and the fixing blocks are in contact with the surface of the side pole. An elastic rope is provided on the storage rod at the top of the main pole, and the two ends of the elastic rope are connected to the storage rod at the top of the side pole, which is used to pull the side pole to rotate towards the main pole.

[0012] Furthermore, a plastic film is installed on the bottom surface of the cabin, and the plastic film is attached to the inner wall of the cabin with Velcro.

[0013] The principles and beneficial effects of the technical solution are as follows:

[0014] This invention provides a portable micro-hyperbaric oxygen chamber. A support frame consisting of a main rod, secondary rod, side rods, a storage rod, and connecting rods supports the chamber, facilitating patient entry into the uninflated chamber. By rotating the secondary rods and side rods and extending the storage rod, the entire support frame can be unfolded. The chamber surface connects to the support frame and unfolds together with it, eliminating the need for staff to assemble each component individually and then support the chamber, thus reducing the workload for staff. For storage, simply fold the storage rod and retract it into the other rods to fold the support frame. The chamber folds along with the support frame, making the device easy to store and carry. Furthermore, with the support frame folded, all components are connected together, eliminating the need for individual disassembly and preventing loss, further enhancing portability.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0026] like Figures 1-9As shown, a portable micro-pressure oxygen chamber includes a chamber body 1 and a support frame 2 for supporting the chamber body 1. The chamber body 1 is made of a flexible, sealing material, with a transparent observation window on its surface for observing the patient's condition, and a sealable opening for easy access. When the opening is closed, the entire chamber body 1 is sealed. The chamber body 1 has a connecting part for connecting to an existing oxygen generation pressure regulation system for oxygen filling and discharging. The support frame 2 has several connecting rings 201, which are connected to corresponding connecting parts 101 on the surface of the chamber body 1. The connecting parts 101 are made of flexible material. The support frame 2 includes symmetrically arranged main rods 3, secondary rods 4, side rods 5, and storage rods 6. Storage rods 6 are slidably disposed within the main rods 3, secondary rods 4, and side rods 5. The storage rods 6 have positioning components inside them to restrict storage. The position of rod 6: The storage rod 6 includes a telescopic rod 601 and a crossbar 602 rotatably connected to the end of the telescopic rod 601. The main rod 3, the auxiliary rod 4, the side rods 5, and the storage rod 6 are each arranged in two sets. The ends of the two sets of crossbars 602 that are opposite each other are connected to the connecting rod 7, which connects the rods on both sides. A locking component is provided at the connection between the crossbar 602 and the connecting rod 7 to limit the rotation of the crossbar 602 relative to the connecting rod 7. The main rod 3 is inverted T-shaped, and its bottom ends are rotatably connected to the two sets of auxiliary rods 4 respectively. The bottom of the main rod 3, the auxiliary rods 4, and the storage rod 6 form a closed ring to support the bottom edge of the cabin 1. The bottom ends of the storage rod 6 inside the main rod 3 pass through the sliding groove 303 and are connected to the two sets of side rods 5 respectively. The main rod 3 and the two sets of side rods 5 form a three-pronged shape, which, together with the storage rod 6, supports the top of the cabin 1.

[0027] In use, the device is in its retracted state. The operator simply pulls the connecting rod 7, causing the crossbars 602 at both ends to rotate until they are parallel to the connecting rod 7. These crossbars 602 are then locked to the connecting rod 7 via a locking assembly, forming a single rod that expands the wide side of the cabin 1. Next, the auxiliary rod 4 is rotated until it is parallel to the bottom of the main rod 3. Then, the single rod at the end of the auxiliary rod 4, consisting of the crossbars 602 and the connecting rod 7, is pulled, causing the telescopic rod 601 to extend from the auxiliary rod 4 and be fixed by a positioning assembly. This creates a closed loop at the bottom of the main rod 3, along with the auxiliary rod 4, the retractable rod 6, and the connecting rod 7, thus expanding the bottom edge of the cabin 1. Then, the side rods 5 on both sides of the main rod 3 are rotated, causing them to expand the top two ends of the cabin 1 to the sides. Finally, the main rod 3 and the retractable rods 5 are lifted. The storage rod 6 extends to support the top of the cabin 1, keeping it unfolded even when not inflated, facilitating entry for patients or staff. The entire process requires only simple lifting actions from the staff, eliminating the need for step-by-step assembly of individual components. Furthermore, the cabin 1 unfolds along with the support frame 2, eliminating the need for separate connection between the support frame 2 and the cabin 1, effectively reducing staff workload. After use, folding the storage rods 6 folds the wide side of the cabin 1, and then rotating the auxiliary rod 4 and side rod 5 folds the long side, quickly completing the storage of the cabin 1 for easy carrying by staff. This replaces the traditional method of disassembling the support frame components, ensuring the support frame 2 remains a single unit after storage, preventing the loss of parts.

[0028] In this embodiment, the positioning component includes a positioning pin 606 that slides through the telescopic rod 601 and a positioning spring 605 that pushes the positioning pin 606 to move. The end edge of the positioning pin 606 is rounded and located in the positioning hole 607. The main rod 3, the auxiliary rod 4, and the side rod 5 are all provided with corresponding positioning holes 607. The rounded part at the end of the positioning pin 606 is engaged in the positioning hole 607. The positioning spring 605 provides sufficient force to prevent the positioning pin 606 from retracting, thereby locking the telescopic rod 601 through the positioning pin 606 and preventing it from moving. When moving the telescopic rod 601, it is only necessary to push the telescopic rod 601 with force. When the force is greater than the elastic force provided by the positioning spring 605, the positioning pin 606 will exit the positioning hole 607 under the action of the rounded corner. This realizes the extension and retraction of the storage rod 6 on the main rod 3, the auxiliary rod 4, and the side rod 5, so as to support the cabin 1. At the same time, it can be stored when not in use, reducing the volume and making it easy to carry.

[0029] In this embodiment, the locking assembly includes a pin 603 that slides through the end of the crossbar 602 and a compression spring 604 that pushes the pin 603 to move. The end of the pin 603 passes through the insertion hole 705 at the end of the connecting rod 7. The connecting rod 7 is provided with a pull rod 701 and a return spring 702 that limits the position of the pull rod 701. The bottom end of the pull rod 701 is provided with a pressing plate 703. The side of the pressing plate 703 is inclined and contacts the end of the pin 603. The top end of the pull rod 701 extends out of the connecting rod 7. Pulling the connecting rod 7 causes the crossbars 602 at both ends to rotate, bringing the two sets of crossbars 602 to a horizontal position on the connecting rod 7. This aligns the pin 603 with the insertion hole 705 on the connecting rod 7. Under the action of the compression spring 604, the pin 603 inserts into the insertion hole 705, thus connecting the two sets of crossbars 602 with the connecting rod 7 into a single rod. This expands the wide side of the cabin 1 and restricts the position of the crossbars 602, preventing them from rotating relative to the telescopic rod 601, which could cause the support frame 2 to fold and affect its use. When storing, the operator only needs to pull the lever 701 until the pressing plate 703 moves. The inclined side of the pressing plate 703 presses the pin 603, thus removing the pin 603 from the insertion hole 705 and releasing the lock between the crossbar 602 and the connecting rod 7. This allows the crossbar 602 to rotate again, enabling quick storage.

[0030] In this embodiment, a handle 704 is provided on the connecting rod 7, and a horizontal plate is provided at the top of the pull rod 701, with the horizontal plate located directly below the handle 704. The operator can easily push and pull the connecting rod 7 through the handle 704, and the horizontal plate allows the operator to pull the pull rod 701 with their fingers while holding the handle 704, making it convenient and effortless.

[0031] In this embodiment, a limiting groove 302 is formed at the bottom of the main rod 3, and an insert block 301 is slidably disposed in the limiting groove 302. The end of the insert block 301 passes through a slot 403 on the secondary rod 4 to limit the rotation of the secondary rod 4. After the secondary rod 4 is rotated to be parallel to the bottom of the main rod 3, the insert block 301 is pushed into the slot 403 to lock the secondary rod 4 and prevent it from rotating, thereby improving the stability of the device when it is deployed.

[0032] In this embodiment, a support rod 401 is hinged to the secondary rod 4. The top end of the support rod 401 is hooked onto the side rod 5. Both the side rod 5 and the support rod 401 are equipped with magnetic plates 402, and the two sets of magnetic plates 402 are positioned correspondingly. The support rod 401 can support the side rod 5, increasing the structural strength of the device when it is unfolded. When storing, simply separate the hook at the top end of the support rod 401 from the side rod 5, rotate the support rod 401 until it is parallel to the secondary rod 4, and the support rod 401 will be attracted and fixed by the magnetic plates 402 on the secondary rod 4.

[0033] In this embodiment, fixing blocks 304 are provided on both sides of the main rod 3. The fixing blocks 304 are in contact with the surface of the side rods 5. An elastic rope 8 is provided on the storage rod 6 at the top of the main rod 3. The two ends of the elastic rope 8 are connected to the storage rod 6 at the top of the side rods 5, and are used to pull the side rods 5 to rotate toward the main rod 3. When the device is deployed, when the storage rod 6 on the main rod 3 is pulled upward, it drives the side rods 5 on both sides of the main rod 3 to move upward synchronously. When the side rods 5 move upward, their rotation points move closer to the fixing blocks 304. Due to the restriction of the fixing blocks 304, the angle between the side rods 5 and the main rod 3 becomes larger, so that the side rods 5 gradually unfold outward while moving upward, thereby supporting the long side of the top of the cabin 1. When retracting, the side rods 5 move downward, their rotation points move away from the fixing blocks 304, and the side rods 5 are tightened by the elastic rope 8, so that they gradually rotate back and are kept retracted on both sides of the main rod 3. No additional operation of the side rods 5 is required by the staff, reducing their workload.

[0034] In this embodiment, a plastic film 102 is provided on the bottom surface of the inner side of the chamber 1, and the plastic film 102 is attached to the inner wall of the chamber 1 by Velcro. The plastic film 102 can prevent the inner wall of the chamber 1 from being contaminated by bodily fluids dripped by the patient. The Velcro attachment method allows the staff to quickly remove the plastic film 102 for disposal after the device is used, and it is also convenient to lay a new plastic film 102 inside the chamber 1. The operation is simple and convenient.

[0035] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific technical solutions or characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
