Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a controllable flow oxygen bag. Background Technology

[0002] When transporting patients requiring oxygen for short distances, oxygen bags are commonly chosen in clinical practice due to their portability, affordability, and ease of inflation. However, current oxygen bags are simply ordinary bags that require manual pressing to expel oxygen. This method of pressing the bag results in unstable airflow, making it difficult to guarantee a stable and accurate oxygen intake for patients requiring a consistent flow rate.

[0003] Therefore, it is necessary to propose an oxygen bag that can stably deliver oxygen. Utility Model Content

[0004] To address or partially address the problems existing in the related technologies, this application provides a controllable flow oxygen bag to deliver a stable flow of oxygen to the patient.

[0005] This application provides a controllable flow oxygen bag, including: an oxygen bag, a positioning unit and a squeezing unit, wherein the positioning unit and the squeezing unit are both disposed on the outer surface of the oxygen bag;

[0006] The positioning unit includes a positioning block, and a through-hole is provided on the side of the positioning block. A rotating shaft is rotatably mounted on the lower part of the side wall of the through-hole. A pressure plate is fixedly mounted on the rotating shaft. An elastic element is provided between the bottom of the pressure plate and the bottom of the through-hole.

[0007] The extrusion unit includes a strap and a fixing groove formed on one side of the positioning block. One end of the strap is fixedly disposed in the fixing groove. The strap wraps around the oxygen bag from the fixing groove and passes through the insertion groove. A torque motor is fixedly installed on the outer wall of the oxygen bag. A winding rod is fixedly disposed on the rotating shaft of the torque motor. One end of the strap located outside the fixing groove is wound around the winding rod.

[0008] Furthermore, there are multiple straps and positioning blocks, with each strap and positioning block corresponding to the other. The straps are evenly spaced to ensure uniform compression of the oxygen bag.

[0009] Furthermore, multiple winding rods are provided, and these multiple winding rods are coaxially connected in sequence. Each of the multiple winding rods corresponds to one of the multiple binding straps. The winding rods are also coaxially connected to the rotation shaft of the torque motor, which serves as the power output.

[0010] Furthermore, the end of the winding rod is provided with a connecting hole with internal threads, and a threaded rod is provided between two adjacent winding rods. The threaded rod is threadedly connected to the connecting hole, thereby connecting the two adjacent winding rods. The winding rod connected to the rotating shaft of the torque motor can be sleeved on the rotating shaft by means of a key connection.

[0011] Furthermore, the width of the winding rod is greater than the width of the binding strap.

[0012] Furthermore, both the positioning unit and the squeezing unit are adhered to the surface of the oxygen bag.

[0013] Furthermore, the rotating shafts are connected to opposite sides of one end of the pressure plate. The end of the pressure plate away from the rotating shaft is pressed upward against the strap by the elastic element, thereby pressing the strap against the upper surface inside the insertion groove. The pressure plate is rotatably connected to the positioning block through the rotating shafts.

[0014] Furthermore, the elastic element is a compression spring, one end of which is fixedly connected to the bottom of the insertion slot, and the other end is connected to the lower surface of the pressure plate.

[0015] Furthermore, the oxygen bag is equipped with a gas flow detector at its outlet. The gas flow detector can detect the flow rate of oxygen output from the oxygen bag, thereby determining whether the torque and speed of the torque motor winding the strap are appropriate.

[0016] Furthermore, the aforementioned controllable flow oxygen bag also includes a controller, which is electrically connected to both the gas flow detector and the torque motor. The controller receives the detection signal from the gas flow detector and controls the output torque of the torque motor according to the detection signal.

[0017] The technical solution provided in this application can include the following beneficial effects: During use, the strap is wrapped around the surface of the oxygen bag, then passed through the top of the pressure plate, and pulled out from the insertion slot to wrap around the winding rod, thus connecting the strap to the winding rod. The rotation shaft of the torque motor drives the winding rod to rotate, thereby winding the strap onto the winding rod. When the strap is wound, it compresses the oxygen bag. The torque motor can output a stable torque to wind the strap, thereby uniformly and stably squeezing out oxygen from the oxygen bag. By controlling the output torque of the torque motor, the flow rate of delivered oxygen can be adjusted, ensuring a stable oxygen flow to the patient. The elastic element presses upward against the pressure plate, causing the pressure plate to rotate upward, pressing the strap against the upper surface inside the insertion slot. This prevents backlash when the torque motor drives the winding rod to wind the strap, maintaining stable winding of the strap and preventing it from loosening.

[0018] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0034] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0035] Please see Figure 1-6 This application provides a controllable flow oxygen bag, including an oxygen bag 100, a positioning unit 200, and a compression unit 300. The positioning unit 200 and the compression unit 300 are both disposed on the outer surface of the oxygen bag 100. The positioning unit 200 and the compression unit 300 can be bonded to the surface of the oxygen bag 100. The oxygen bag 100 is not specially modified and will not be described in detail here. The positioning unit 200 and the compression unit 300 can be directly bonded to the surface of the oxygen bag 100 according to the actual installation situation. It is only necessary to fix them to the surface of the oxygen bag 100.

[0036] See Figure 1 , Figure 2 , Figure 4 and Figure 6In a preferred embodiment, the positioning unit 200 includes a positioning block 210. The side of the positioning block 210 has an insertion groove 211 that penetrates the positioning block 210. A rotating shaft 2111 is rotatably mounted on the lower part of the inner wall of the insertion groove 211. A pressure plate 2112 is fixedly mounted on one end of the rotating shaft 2111. An elastic element, which is a compression spring 2113, is installed at the bottom of the pressure plate 2112. When the compression spring 2113 releases its elastic potential energy, the top of the pressure plate 2112 contacts the upper surface inside the insertion groove 211.

[0037] See Figure 1 , Figure 5 and Figure 6 In a further preferred embodiment, the compression unit 300 includes a strap 320 and a fixing groove 310 formed on one side of the positioning block 210. One end of the strap 320 is fixed inside the fixing groove 310, and the other end of the strap 320 extends out of the fixing groove 310 and surrounds the oxygen bag 100.

[0038] The width of the strap 320 is smaller than the width of the insertion slot 211. The strap 320 passes through the top of the pressure plate 2112 and through the insertion slot 211. The pressure plate 2112 can be rotated at a certain angle by the pivot 2111, further opening the upper part of the insertion slot 211, so that the strap 320 can pass through the positioning block 210. Then, the pressure plate 2112 is rotated upward by the compression spring 2113, so that the pressure plate 2112 presses the strap 320 against the upper surface inside the insertion slot 211. This prevents the strap 320 from being pulled back when the torque motor 330 drives the winding rod 340 to wind up the strap 320, thus maintaining the stable winding of the strap 320 and preventing it from loosening.

[0039] The fixing groove 310 is located on the positioning block 210. One end of the strap 320 is fixed in the fixing groove 310, which can keep the strap 320 stable and prevent it from loosening under tension. The strap 320 is wrapped around the oxygen bag 100 so that the strap 320 can be squeezed from multiple angles of the oxygen bag 100 when it contracts, further outputting the oxygen in the oxygen bag 100.

[0040] See Figure 1 and Figure 3 In a further preferred embodiment, a torque motor 330 is fixedly installed on the outer wall of the oxygen bag 100, and the rotating shaft of the torque motor 330 is fixedly connected to a winding rod 340.

[0041] One end of the strap 320 is connected to the winding rod 340 through the insertion slot 211. The winding rod 340 is then rotated by the rotating shaft of the torque motor 330, which in turn rotates the winding rod 340. The strap 320 is continuously wound up by the winding rod 340. The winding rod 340 and the strap 320 are in the same position, meaning that the strap 320 will not deviate in angle when it is wound around the winding rod 340. It will only be wound on the winding rod 340.

[0042] See Figure 1 Preferably, the end of the winding rod 340 is provided with a connecting hole 341, the connecting hole 341 is provided with an internal thread, and a threaded rod 342 is fixedly installed between two adjacent winding rods 340. The threaded rod 342 is threadedly connected to the connecting hole 341. The internal thread of the connecting hole 341 facilitates the screwing in and out of the threaded rod 342. The winding rods 340 can be connected, added, or removed according to the number of straps 320, so that each winding rod 340 corresponds to each strap 320. The connecting hole 341 and the threaded rod 342 facilitate the connection and disassembly of the winding rods 340 together.

[0043] See Figure 1 and Figure 5 More preferably, there are three positioning units 200 evenly arranged on the surface of the oxygen bag 100, and three straps 320 evenly wrapped around the surface of the oxygen bag 100. By connecting the three straps 320 with the three winding rods 340, the oxygen bag 100 can be squeezed at the same time, so that the oxygen flow rate remains uniform and stable.

[0044] In some embodiments, the outlet of the oxygen bag 100 is equipped with a gas flow detector, which can detect the flow rate of oxygen output by the oxygen bag 100, thereby determining whether the torque and speed of the torque motor 330 winding the strap are appropriate.

[0045] In some embodiments, the controllable flow oxygen bag further includes a controller, which is electrically connected to both the gas flow detector and the torque motor 330. The controller receives the detection signal from the gas flow detector and controls the output torque of the torque motor 330 according to the detection signal, thereby further ensuring the stability of the output oxygen flow. The controller may be a microcontroller, etc.
