Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a ventilator mask that facilitates drinking and provides water temperature indication. Background Technology

[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation, are widely used for respiratory failure caused by various reasons, anesthetic respiratory management during major surgery, respiratory support therapy, and emergency resuscitation, occupying a very important position in the field of modern medicine. Patients using ventilators need to wear a breathing mask, which connects the ventilator tubing to the patient's mouth and nose, thereby delivering air into the airway. The mask is worn over the patient's mouth and nose and is generally worn for a considerable period. When patients continuously receive high-flow oxygen for extended periods, they are prone to dry mouth and throat, and insufficient airway humidification; in such cases, adequate water intake is necessary. Traditional breathing masks do not have a drinking function. Patients need to temporarily remove the mask when drinking or eating. However, patients who require long-term oxygen therapy are generally seriously ill and weak, and their drinking or eating speed is very slow. This results in the patient being out of the oxygen mask for too long when drinking or eating, and the oxygen inhalation being stopped for too long. This can easily cause the patient's blood oxygen saturation to drop, leading to symptoms of hypoxia such as chest tightness and shortness of breath. In addition, the frequent removal and putting on of the mask and the high frequency of stopping the ventilator lead to poor patient compliance with ventilator use and a decrease in treatment effectiveness.

[0003] To facilitate patients' drinking during oxygen therapy and reduce the need for frequent mask removal and replacement, manufacturers have upgraded ventilator masks by incorporating a drinking port on the mask itself. For example, Chinese utility model patent CN217567067U discloses a non-invasive ventilator mask for convenient drinking. The mask features a ventilator interface and a drinking port, with the drinking port located below the ventilator interface. A detachable sealing cap is attached to the end of the drinking port, connected to it by a flexible band. While this patented technology eliminates the need for frequent mask removal and replacement to ensure an airtight seal, patients still need to remove the sealing cap, insert a straw through the drinking port into their mouth, and then remove the straw after drinking before closing the drinking port. This process is cumbersome, requiring frequent removal and tightening of the sealing cap and insertion / removal of the straw. Summary of the Invention

[0004] The present invention aims to provide a ventilator mask that facilitates drinking and provides water temperature indication, in order to solve the technical problem of existing masks with drinking ports on the mask body, which require patients to frequently remove and reseal the cap when drinking, resulting in cumbersome operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ventilator mask for easy drinking and water temperature indication includes a mask body with a drinking port and a detachable drinking assembly attached to the drinking port. The drinking assembly includes a mounting component and a drinking tube. The mounting component is connected to the drinking port and has a mounting cavity extending along its axis. One end of the drinking tube passes through the mounting cavity and extends into the mask body, and the drinking tube is slidably connected to the mounting cavity. The drinking tube includes a suction section, an adjustment section, and a temperature-sensing section. The suction section is made of a deformable material, and its outer diameter is larger than the inner diameter of the mounting cavity. When the drinking tube is pulled outward, the suction section deforms into the mounting cavity to close the opening of the suction section. The temperature-sensing section is provided with a material that changes color with temperature and is located outside the mounting cavity.

[0007] Beneficial effects:

[0008] 1. By incorporating a drinking component, when the patient needs to drink, the drinking tube is pushed inward, allowing the suction section to move within the mask body and easily reach the patient's mouth. The temperature-sensing section is then inserted into the water bottle, or connected to a straw or other delivery tube, allowing the patient to drink. After drinking, the drinking tube is pulled outward, causing the suction section to retract from the patient's mouth. This avoids the suction section remaining within the mask body, which could interfere with oxygen delivery and cause discomfort. Because the outer diameter of the suction section is larger than the inner diameter of the mounting cavity, when the drinking tube is pulled outward, the suction section enters the mounting cavity. The mounting cavity compresses the outer diameter of the suction section, causing it to deform and seal its opening and the drinking spout. This achieves the goal of sealing the drinking spout when not drinking, ensuring the airtightness of the mask body. Compared to existing technologies, this application only requires pushing the drinking tube inward when drinking water and pulling it outward after drinking, while simultaneously closing the drinking spout. The operation process is simple. Furthermore, the sucking section is always located inside, which reduces the risk of external contamination compared to inserting the straw into the mask during use.

[0009] 2. The outer diameter of the sucking section is larger than the inner diameter of the installation cavity. That is, the outer diameter of the sucking section is larger than that of the other two sections of the drinking tube. Compared with direct insertion into the straw for sucking, the sucking section of this application is more convenient for the patient to hold in their mouth and is less likely to fall out of the mouth.

[0010] 3. The drinking water component is detachably mounted on the drinking spout, making it easy to remove and replace, improving safety and comfort during use; avoiding the problem of odor or bacterial growth caused by using the same drinking water component for a long time.

[0011] 4. The drinking tube is slidably connected to the mounting cavity, which makes it easy to adjust the length of the tube that extends into the mask body to suit different patients and to deliver the sucking section to the patient's mouth for drinking or eating.

[0012] 5. By installing a material that changes color with temperature on the temperature-sensitive section, the color of the temperature-sensitive section changes when the water temperature is high, which can intuitively remind nursing staff and solve the problem of patients being scalded by high temperature. Moreover, the temperature-sensitive section is located outside the installation cavity, making it easier for caregivers to observe and better serve as a reminder. In addition, by connecting the temperature-sensitive section to other delivery tubes, it can also be used for patients to receive liquid food or receive nutritional fluids.

[0013] Preferably, as an improvement, the outer wall of the adjusting section is provided with a number of arc-shaped grooves along its length, the inner wall of the mounting cavity is provided with a mounting groove, and an elastic limiting member that cooperates with the arc-shaped groove is provided in the mounting groove. The top of the elastic limiting member is used to insert into the arc-shaped groove and is slidably connected with the arc-shaped groove.

[0014] Beneficial effects:

[0015] 1. Several arc-shaped grooves are provided to facilitate the limiting and fixing of the drinking water pipe, ensuring that the drinking water pipe will not move after being adjusted to an appropriate distance; specifically, when the top of the elastic limiting member is inserted into one of the arc-shaped grooves, it fixes the drinking water pipe. If the drinking water pipe is pulled inward or outward, the arc-shaped wall of the arc-shaped groove will squeeze the elastic limiting member, and the elastic limiting member will be compressed and extend into the installation groove. At this time, the length of the drinking water pipe can be adjusted again.

[0016] 2. The arc-shaped groove can both limit the movement and facilitate the repositioning of the drinking water pipe when it is under stress.

[0017] Preferably, as an improvement, a groove is provided on the outer wall of the suction section, and when the suction section is located in the mounting cavity, the elastic limiting member is inserted into the groove.

[0018] Beneficial effects:

[0019] 1. A groove is set on the outer wall of the sucking segment. When the patient sucks to drink, negative pressure is generated at the groove, and the sucking segment tends to fit into the patient's mouth, thus generating a certain resistance, which can further prevent the sucking segment from slipping out of the mouth during sucking.

[0020] 2. In addition, when the drinking tube is pulled outward to move the suction section into the installation cavity, the groove allows the elastic limiting member to be inserted, thereby limiting the suction section and preventing the entire drinking tube from being pulled out of the installation cavity.

[0021] Preferably, as an improvement, the elastic limiting member includes a locking rod and a spring, one end of the spring being fixed to the bottom of the mounting groove and the other end being connected to the bottom of the locking rod; the locking rod is slidably connected to the mounting groove, the top of the locking rod being spherical and extending out of the mounting groove for insertion into the arc-shaped groove of the adjustment section.

[0022] Beneficial effects: By setting the top of the lever to be spherical, the curved spherical surface plays a certain guiding role when pulling, which can further reduce the resistance when pulling the drinking hose and make it easier to adjust the length of the drinking hose.

[0023] Preferably, as an improvement, the inner wall of the mounting cavity is also provided with a strip groove communicating with it, the left and right ends of the strip groove pass through the mounting component, and a strip rod is provided on the adjustment section, the strip rod being slidably disposed in the strip groove.

[0024] Beneficial effects: It can guide and limit the water pipe, while preventing the water pipe from rotating circumferentially.

[0025] Preferably, as an improvement, the temperature sensing section is detachably provided with an adapter, the adapter is provided with a through adapter hole, a deformable seal is provided in the adapter hole, and the seal is provided with a closed through hole, which opens when an external force is applied to the through hole.

[0026] Beneficial effects:

[0027] 1. The detachable adapter makes it easy to disassemble and replace; and by connecting to a straw or other delivery tube through the adapter, the liquid enters the drinking tube from inside the adapter, which is cleaner and more hygienic than directly extending the temperature sensor into the water cup.

[0028] 2. A closed through hole is provided on the seal. When not in use, the adapter is in a closed state, which can effectively ensure the hygiene of the water pipe inside and reduce the risk of contamination. When in use, the straw is inserted into the through hole. Since the seal can deform, the through hole opens under the squeezing action of the straw. At the same time, the inside of the through hole applies a reaction force to the outer wall of the straw, which plays a clamping role.

[0029] Preferably, as an improvement, the seal is a two-part seal, each part having a concave surface and a convex surface. The concave and convex surfaces on the two parts cooperate to form a wave-shaped closed through hole. When an external force is applied to the through hole, the concave and convex surfaces of the seal deform, and the through hole opens.

[0030] Beneficial effects: By setting up concave and convex mating surfaces, when the straw is inserted into the through hole, the clamping force of the seal on the straw can be further improved, ensuring the stability of the connection. Attached Figure Description

[0038] The following detailed description illustrates the specific implementation method:

[0039] The reference numerals in the accompanying drawings include: mask body 1, ventilator interface 11, oxygen tubing 12, connecting tube 2, mounting component 3, mounting cavity 31, connecting cavity 311, mounting groove 32, drinking tube 4, suction section 41, groove 411, vertical side wall 4111, arc-shaped side wall 4112, adjustment section 42, arc-shaped groove 421, temperature sensing section 43, elastic limiting component 5, locking rod 51, spring 52, adapter 6, sealing component 61, through hole 62, strip groove 7, and strip rod 71.

[0040] Example 1

[0041] like Figures 1-4 As shown, a ventilator mask for easy drinking and water temperature indication includes a mask body 1. The mask body 1 is provided with a ventilator interface 11 and a drinking port. The ventilator interface 11 is used to connect to the oxygen tubing 12. The drinking port is located below the ventilator interface 11. To avoid interference between the drinking port and the oxygen tubing 12, the drinking port and the ventilator interface 11 are offset. A drinking component is detachably provided on the drinking port. For easy installation, in this embodiment, a connecting tube 2 is glued to the drinking port. The outer wall of the connecting tube 2 is provided with external threads. The drinking component includes a mounting part 3 and a drinking tube 4. The mounting part 3 is connected to the drinking port. Specifically, the mounting part 3 is tubular. The end of the mounting part 3 near the connecting tube 2 is provided with a connecting cavity 311. The inner wall of the connecting cavity 311 is provided with internal threads. The mounting part 3 is threadedly connected to the connecting tube 2, or the connecting tube 2 is tightened and connected in the connecting cavity 311 for easy disassembly and replacement.

[0042] like Figure 2 As shown, the mounting component 3 has a mounting cavity 31 extending along its axis. One end of the drinking tube 4 passes through the mounting cavity 31 and extends into the mask body 1, and the drinking tube 4 is slidably connected to the mounting cavity 31. The drinking tube 4 includes a suction section 41, an adjustment section 42, and a temperature sensing section 43. The suction section 41 is made of a deformable material, specifically food-grade silicone or latex. The outer diameter of the suction section 41 is larger than the inner diameter of the mounting cavity 31. In this embodiment, the longitudinal section of the suction section 41 is an isosceles trapezoid or a right trapezoid, such as... Figure 4As shown, when the drinking tube 4 is pulled outward, the sucking section 41 enters the mounting cavity 31 and is deformed by the cavity wall of the mounting cavity 31, thereby sealing the opening of the sucking section 41 and blocking the mounting cavity 31, thus sealing the drinking mouth; a groove 411 is also provided on the outer wall of the sucking section 41. When the patient sucks to drink, negative pressure is generated at the groove 411, and the sucking section 41 tends to fit into the patient's mouth, thereby generating a certain resistance, which can further prevent the sucking section 41 from slipping out of the mouth during sucking.

[0043] The adjusting section 42 can also be made of latex material, with a slightly higher hardness than the sucking section 41, to facilitate sliding of the adjusting section 42 within the mounting cavity 31 when the drinking tube 4 is pushed or pulled. To facilitate limiting the position of the drinking tube 4, this embodiment provides several arc-shaped grooves 421 along the length of the outer wall of the adjusting section 42, and a mounting groove 32 on the inner wall of the mounting cavity 31. An elastic limiting member 5, which cooperates with the arc-shaped groove 421, is provided within the mounting groove 32. The top of the elastic limiting member 5 is inserted into the arc-shaped groove 421 and slidably connected to it. Specifically, as shown... Figure 3 As shown, the elastic limiting member 5 includes a locking rod 51 and a spring 52. One end of the spring 52 is fixed to the bottom of the mounting groove 32, and the other end is connected to the bottom of the locking rod 51. The locking rod 51 is slidably connected to the mounting groove 32, and the top of the locking rod 51 is spherical for insertion into the arc-shaped groove 421.

[0044] When the locking rod 51 is inserted into one of the arc-shaped grooves 421, it fixes the drinking pipe 4. When the drinking pipe 4 is pulled inward or outward, the arc-shaped wall of the arc-shaped groove 421 presses against the top of the locking rod 51, and the locking rod 51 is pressed into the mounting groove 32. At this time, the spring 52 is in a compressed state, and the length of the drinking pipe 4 can be adjusted again. When the locking rod 51 is aligned with the next arc-shaped groove 421, the locking rod 51 loses the pressing force of the outer wall of the adjusting section 42, the spring 52 resets and pushes the locking rod 51 upward, and the locking rod 51 is inserted into the arc-shaped groove 421, which again limits and fixes the drinking pipe 4. Figure 4 As shown, when the drinking tube 4 is pulled outward until the suction section 41 is located in the mounting cavity 31, the locking rod 51 is inserted into the groove 411 of the suction section 41, thereby limiting the suction section 41 and preventing the entire drinking tube 4 from being pulled out of the mounting cavity 31. When drinking is needed, the drinking tube 4 is pushed inward, and the groove 411 gradually disengages from the locking rod 51. The suction section 41 extends from the mounting cavity 31 into the mask body 1. The drinking tube 4 is pushed forward until the suction section 41 is inserted into the patient's mouth.

[0045] The temperature-sensitive section 43 is equipped with a material that changes color with temperature. This color-changing material is existing technology. Specifically, the temperature-sensitive section 43 can be made using existing color-changing straws, or temperature-sensitive color-changing microcapsules can be coated on the outside of the temperature-sensitive section 43. The temperature-sensitive section 43 is located outside the installation cavity 31. By equipping the temperature-sensitive section 43 with a material that changes color with temperature, the color of the temperature-sensitive section 43 changes when the water temperature is high, making it easy to visually remind caregivers and solving the problem of patients being scalded by high temperatures. Moreover, the temperature-sensitive section 43 is located outside the installation cavity 31, making it easier for caregivers to observe and providing a better warning. In addition, when in use, the temperature-sensitive section 43 can be inserted into a water cup for drinking, or connected to other delivery tubes or straws for drinking water or consuming liquid food.

[0046] The free end of the temperature sensing section 43 is detachably equipped with an adapter 6, and the specific temperature sensing section 43 can be tightly connected to the adapter 6; for example... Figure 2 As shown, the adapter 6 has a through-hole, and a deformable seal 61 is installed inside the adapter hole. The seal 61 can be made of soft silicone, and a closed through-hole 62 is provided on the seal 61. When an external force is applied to the through-hole 62, the through-hole 62 opens. The adapter 6 connects to a straw or other delivery tube, and the liquid enters the drinking tube 4 from inside the adapter 6. This is cleaner and more hygienic than directly inserting the temperature sensing section 43 into the water cup. Furthermore, the closed through-hole 62 on the seal 61 ensures that the adapter 6 is in a closed state when not in use, effectively maintaining the hygiene of the internal tubing of the drinking tube 4 and reducing the risk of contamination. When in use, the straw is inserted into the through-hole 62. Because the seal 61 is deformable, the through-hole 62 opens under the pressure of the straw, and simultaneously, the inside of the through-hole 62 exerts a reaction force on the outer wall of the straw, providing a clamping effect.

[0047] The following are the instructions for using a ventilator mask that provides easy access to drinking water and water temperature indicators:

[0048] When using, install the mounting part 3 onto the connecting pipe 2, such as Figure 4 As shown, when the patient is not drinking water, the suction section 41 of the drinking tube 4 is located inside the mounting cavity 31, and under the squeezing action of the mounting cavity 31, the suction section 41 is in a squeezed state. Both the opening of the suction section 41 and the drinking port are in a closed state, ensuring an airtight seal inside the mask body 1 and not affecting the patient's normal oxygen intake; Figure 2As shown, when the patient needs to drink water, the drinking tube 4 is pushed forward, and the groove 411 of the suction section 41 gradually disengages from the locking lever 51. The suction section 41 extends from the mounting cavity 31 into the mask body 1. At this time, the opening of the suction section 41 opens. If the patient continues to push forward, the locking lever 51 extends into the first arc-shaped groove 421 on the adjusting section 42. If the suction section 41 has already reached the patient's mouth, the pushing is stopped. If the suction section 41 has not yet reached the patient's mouth, the drinking tube 4 is pushed inward until the locking lever 51 is engaged in the next arc-shaped groove 421, and the suction section 41 is located in the correct position. The straw is placed inside the patient's mouth; then the straw is inserted into the adapter hole, the straw squeezes the closed through hole 62, the through hole 62 opens, the straw connects to the drinking tube 4, and the straw is clamped by the inner wall of the through hole 62; the patient can drink water by sucking; when the patient drinks water, the water passes through the temperature sensing section 43, the adjustment section 42 and the sucking section 41 in sequence. If the drinking water is hot and the temperature is high, the color of the temperature sensing section 43 changes, indicating to the caregiver that the water temperature is too high, and the straw can be pulled out from the adapter 6; after the patient finishes drinking water, the drinking tube 4 is pulled outwards, so that the sucking section 41 returns to the installation cavity 31.

[0049] Compared to existing technologies, this application simplifies the drinking process by requiring only pushing the drinking tube 4 inwards and pulling it outwards after drinking, while simultaneously closing the drinking spout. Furthermore, the suction section 41 remains internal, reducing the risk of external contamination compared to inserting the straw into the mask during drinking. Additionally, the outer diameter of the suction section 41 is larger than the inner diameter of the mounting cavity 31, making it easier for the patient to hold in their mouth and preventing it from slipping out. A groove 411 is provided on the outer wall of the suction section 41; when the patient sucks, negative pressure is generated at the groove 411, further preventing the suction section 41 from slipping out of the mouth. Moreover, the drinking component is detachably mounted on the drinking spout, facilitating disassembly and replacement, improving safety and comfort, and avoiding the problems of odor or bacterial growth that can occur from prolonged use of a single drinking component.

[0050] Example 2

[0051] The difference between this embodiment and Embodiment 1 is that, as Figure 5 As shown, the sealing element 61 is a two-lobed structure, with a concave surface and a convex surface on each lobe. The concave and convex surfaces on the two lobes cooperate to form a wave-shaped closed through hole 62. In this embodiment, there are multiple concave and convex surfaces on the two lobes. When an external force is applied to the through hole 62, the concave and convex surfaces of the sealing element 61 deform, and the through hole 62 opens.

[0052] Example 3

[0053] The difference between this embodiment and Embodiment 1 is that, as Figure 6As shown, a strip groove 7 communicating with the inner wall of the mounting cavity 31 is also provided. The left and right ends of the strip groove 7 pass through the mounting piece 3. A strip rod 71 is provided on the adjusting section 42. The strip rod 71 is slidably disposed in the strip groove 7. This can guide and limit the water pipe 4, while preventing the water pipe 4 from rotating circumferentially. Alternatively, the strip groove 7 can be set along several arc grooves 421. The strip groove 7 communicates with the arc grooves 421, and the depth of the strip groove 7 is less than the depth of the arc grooves 421. A clamping rod 51 is used as the strip rod 71. The clamping rod 51 slides in the strip groove 7. When it encounters an arc groove 421, the clamping rod 51 extends into the arc groove 421. When the water pipe 4 is pulled further, the clamping rod 51 disengages from the arc groove 421 and re-enters the strip groove 7 (not shown in the figure).

[0054] Example 4

[0055] The difference between this embodiment and Embodiment 1 is that, as Figure 7 As shown, the groove 411 is a "D" shape with an unsealed bottom. The side wall near the end of the suction section 41 is a vertical surface, and the side wall corresponding to the vertical surface is an arc-shaped surface. When the locking rod 51 is inserted into the groove 411, the vertical side wall 4111 limits the locking rod 51, preventing it from being pulled outwards. This avoids the problem of the drinking tube 4 being completely pulled out of the mounting cavity 31 due to excessive force. The side wall corresponding to the vertical side wall 4111 is an arc-shaped side wall 4112. The arc-shaped side wall 4112 contacts the spherical surface at the top of the locking rod 51. When the drinking tube 4 is pushed inwards, the arc-shaped side wall 4112 applies a downward force to the locking rod 51. The locking rod 51 extends into the mounting groove 32 and disengages from the groove 411. At this time, the drinking tube 4 can continue to be pushed inwards, thereby extending the suction section 41 into the mask body 1.

[0056] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not described in detail 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. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
