Respirator mask for emergency treatment

Abstract

The respirator mask comprises a mask body and a bandage, the bandage is fixedly arranged on the outer wall of the mask body and has an elastic function, and a connector fixedly penetrates through the right side of the mask body. Through the design of the locking function, after the lifting pin and the limiting block penetrate through the insertion hole and apply thrust to the sliding ring, the mounting sleeve is rotated, so that the mounting sleeve drives the lifting pin and the limiting block to coincide with the clamping groove, and then through the design of the reset function, the sliding ring pushes the limiting block to be clamped into the clamping groove; namely, the state that the connecting pipe is inserted into the connector is locked, and the stable effect after the connecting pipe and the connector are combined is improved. Through the design of mechanical linkage, when the lifting pin exerts extrusion force on the sliding ring, the circular ring sucks gas in the air cushion into the shell, and when the sliding ring resets, the gas in the shell flows back into the air cushion, so that the expanded air cushion clamps the connecting pipe sleeving the limiting sleeve; and therefore, the sealing effect after the connecting pipe and the connector are combined is improved.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an emergency ventilator mask. Background Technology

[0002] A breathing mask is a structure placed over the user's mouth and nose to connect to a breathing apparatus and deliver gas to the user. A traditional breathing mask includes a mask body, an inlet connector, and an air bag located at the end of the mask body that contacts the user's face. The inlet connector connects to the mask body. During use, the mask body is secured to the user's head, and the air bag is fitted to the face. The inlet connector connects to the ventilator, and gas enters the mask body through the inlet connector for the user to breathe. However, the connection of the inlet tube to the tubing in existing emergency care breathing masks is cumbersome and time-consuming, reducing work efficiency.

[0003] The patent published under announcement number "CN217745291U" is titled "An Emergency Nursing Respiratory Mask." While the device in this document addresses the aforementioned problems, it only combines the connecting tube and the inlet tube through the engagement of a locking block and a locking groove, and the engagement of a metal ring and an annular groove. This assembly method cannot lock the inlet tube and connecting tube in their combined state, making it easy for the connecting tube to detach from the inlet tube during use, thus affecting the patient's treatment progress. Therefore, this utility model designs an emergency ventilator mask to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an emergency ventilator mask to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an emergency ventilator mask, comprising a mask body and a strap, wherein the strap is fixed to the outer wall of the mask body and has an elastic function; a connector is fixedly inserted through the right side of the mask body; a connecting tube is provided inside the connector; an installation sleeve is fixedly fitted outside the connecting tube; top pins are fixedly provided at the upper and lower ends of the outer left side of the installation sleeve; a limiting block is fixedly provided on the left side of the outer wall of the top pin; a locking component is provided outside the connector; the locking component includes an installation ring fixedly fitted outside the left side of the connector; a sliding ring is slidably fitted outside the right side of the connector; several springs are fixedly provided between the sliding ring and the installation ring; a limiting ring is fixedly fitted outside the right side of the connector; insertion holes are integrally provided at the upper and lower ends of the limiting ring; guide holes are integrally provided at the front and rear ends of the limiting ring; and slots are integrally provided at the front and rear ends of the limiting ring.

[0006] Furthermore, both the insertion hole and the guide hole are through-hole designs, with the interior of the insertion hole connected to the interior of the guide hole, and the cross-section of the guide hole being smaller than that of the insertion hole.

[0007] Furthermore, a placement plate is fixedly provided on the left side inside the connector, and a limiting sleeve is fixedly provided inside the placement plate. The axis of the limiting sleeve is coaxial with the axis of the connector.

[0008] Furthermore, a housing is fixedly fitted on the outer left side of the connector, a circular ring is slidably connected inside the housing, and an air cushion is fixed inside the connector.

[0009] Furthermore, the upper and lower ends of the left side of the slip ring are fixedly provided with sliding pins, the left end of the sliding pins slides through the housing, and the left end of the sliding pins is fixedly connected to the right end of the ring.

[0010] Furthermore, exhaust pipes are fixedly inserted through the upper and lower ends of the right side of the outer shell, with the end of the exhaust pipe away from the shell fixedly inserted through the connector, and the right end of the exhaust pipe fixedly inserted through the outside of the air cushion.

[0011] Furthermore, the air cushion has a circular cross-section when viewed from the side, and the center of the air cushion is concentric with the center of the connector.

[0012] Furthermore, the housing, mounting ring, slip ring, and connector are all concentrically designed, and the distance between the right end of the housing and the left end of the slip ring is two centimeters.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the design of the locking function, after the top pin and the limiting block pass through the insertion hole and push the slip ring, the mounting sleeve is rotated so that the mounting sleeve drives the top pin and the limiting block to overlap with the slot. Then, through the design of the reset function, the slip ring pushes the limiting block into the slot, thereby locking the state of the connecting pipe inserted into the connector, which improves the stability of the connecting pipe and the connector after combination.

[0015] 2. Through the mechanical linkage design, when the top pin applies pressure to the slip ring, the ring draws the gas in the air cushion into the housing. When the slip ring resets, the gas inside the housing flows back into the air cushion, thereby allowing the expanded air cushion to clamp the connecting pipe that is fitted with the limiting sleeve, thus improving the sealing effect after the connecting pipe and the connector are combined.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figure 1 , Figure 2 , Figure 5As shown, the device includes a cover 1 and a strap 2. The strap 2 is fixed to the outer wall of the cover 1 and has an elastic function. A connector 3 is fixedly inserted through the right side of the cover 1. A connecting tube 4 is provided inside the connector 3. An installation sleeve 5 is fixedly fitted outside the connecting tube 4. A top pin 6 is fixedly provided at the upper and lower ends of the left side of the installation sleeve 5. A limiting block 7 is fixedly provided on the left side of the outer wall of the top pin 6. A locking component 8 is provided outside the connector 3. The locking component 8 includes an installation ring 801 fixedly fitted on the left side of the connector 3. A sliding ring 802 is slidably fitted on the right side of the connector 3. Several springs 803 are fixed between the sliding ring 802 and the installation ring 801. A limiting ring 804 is fixedly fitted on the right side of the connector 3. An insertion hole 805 is integrally provided at the upper and lower ends of the limiting ring 804. A guide hole 806 is integrally provided at the front and rear ends of the limiting ring 804. A slot 807 is integrally provided at the front and rear ends of the limiting ring 804.

[0027] Both the insertion hole 805 and the guide hole 806 are through-hole designs, with the interior of the insertion hole 805 connected to the interior of the guide hole 806. The cross-section of the guide hole 806 is smaller than that of the insertion hole 805. Medical personnel first connect the right end of the connecting tube 4 to the ventilator, then hold the installation sleeve 5 and push the top pin 6 to drive the limiting block 7 through the insertion hole 805, thereby inserting the connecting tube 4 into the connector 3. At this time, the top pin 6 pushes the slip ring 802 to move along the direction of the installation ring 801, and the spring 803 deforms. Then, the installation sleeve 5 is rotated 90 degrees, that is, the top pin 6 moves along the direction of the guide hole 806, thereby aligning the limiting block 7 with the slot 807. The force pushing the top pin 6 is then released, and through the rebound force of the spring 803, the slip ring 802 pushes the top pin 6 to drive the limiting block 7 into the slot 807. This method not only ensures the convenience of assembling the connecting tube 4 and the connector 3, but also ensures the stability of the connected tube 4 and connector 3 after assembly. The medical staff then put the strap 2 on the patient's head so that the mask 1 covers the patient's mouth and nose, thus providing the patient with subsequent oxygen therapy.

[0028] Example 2

[0029] like Figure 2 , Figure 3 , Figure 4As shown, a placement plate 9 is fixedly installed on the left side inside the connector 3, and a limiting sleeve 10 is fixedly installed inside the placement plate 9. The axis of the limiting sleeve 10 is coaxial with the axis of the connector 3. A housing 11 is fixedly installed on the left side outside the connector 3. A ring 12 is slidably connected inside the housing 11. An air cushion 13 is fixedly installed inside the connector 3. Sliding pins 14 are fixedly installed at the upper and lower ends of the left side of the sliding ring 802. The left end of the sliding pin 14 slides through the housing 11, and the left end of the sliding pin 14 is fixedly connected to the right end of the ring 12. The right side of the housing 11 is fixedly connected to the right end of the ring 12. Exhaust pipes 15 are fixedly inserted through the upper and lower ends of the side. The end of the exhaust pipe 15 away from the housing 11 is fixedly inserted through the connector 3, and the right end of the exhaust pipe 15 is fixedly inserted through the outside of the air cushion 13. The air cushion 13 has a circular cross-section when viewed from the side. The center of the air cushion 13 and the center of the connector 3 are concentric. The centers of the housing 11, the mounting ring 801, the slip ring 802, and the connector 3 are all concentric. The distance between the right end of the housing 11 and the left end of the slip ring 802 is two centimeters.

[0030] According to the operation method in Embodiment 1, when the connecting pipe 4 is inserted into the connector 3, the connecting pipe 4 covers the limiting sleeve 10, and the air cushion 13 covers the outside of the connecting pipe 4. When the slip ring 802 moves along the direction of the mounting ring 801, the slip ring 802 drives the sliding pin 14 together with the ring 12 to move to the left along the direction of the housing 11. At this time, the ring 12 draws the gas in the air cushion 13 into the right side of the inside of the housing 11 through the exhaust pipe 15. When the limiting block 7 is inserted into the slot 807, that is, when the slip ring 802 is reset, the slip ring 802 drives the sliding pin 14 to drive the ring 12 to push the gas in the right side of the inside of the housing 11 into the air cushion 13. This allows the expanded air cushion 13 to exert a clamping force on the outside of the connecting pipe 4, thereby sealing the state after the connecting pipe 4 and the connector 3 are combined.
