Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, in particular to a ventilator mask capable of passing a gastric tube. Background Art

[0002] In modern medicine, especially in intensive care units (ICUs), emergency departments, and respiratory medicine departments, patients often require ventilator-assisted ventilation while also having an indwelling gastric tube inserted for reasons such as inability to eat, gastrointestinal decompression, and medication administration. However, conventional ventilator masks currently in use do not adequately account for the presence of a gastric tube, and the simultaneous use of these two devices can lead to frequent problems.

[0003] When traditional ventilator masks fit the face, they do not have a sealing structure specially designed for the passage of a gastric tube. The gastric tube passes through the side of the mask at will, creating a gap between the mask and the face, allowing a large amount of gas to leak out, resulting in unstable gas pressure delivered by the ventilator and inability to accurately reach the set tidal volume, respiratory rate and other parameters, affecting the patient's respiratory support effect and delaying recovery. In addition, the mask lacks a structure to effectively fix the gastric tube. Medical staff can only use simple methods such as tape to stick the gastric tube to the mask or the patient's face. The stickiness of the tape is easily affected by skin oil and sweat, and the gastric tube is easy to shift and slip. Once the gastric tube is loose, it will not only affect gastrointestinal function support, but may even enter the airway by mistake, causing serious consequences such as choking and suffocation. In addition, the gastric tubes used by different patients have different thicknesses, and traditional fixing methods are difficult to adapt to them. The patient's head turning, turning over and other movements can easily cause the gastric tube to bend. The bent gastric tube will hinder the smooth transmission of food, medicine, and gastrointestinal decompression fluid, causing pipeline blockage. Re-clearing the pipeline is time-consuming and labor-intensive, and may also delay the supply of nutrient solution, which is not conducive to the patient's physical recovery.

[0004] In view of the above-mentioned practical problems in clinical practice, there is an urgent need to develop a ventilator mask that can pass through a gastric tube, so as to ensure the proper placement of the gastric tube while ensuring the efficient operation of the ventilator, and provide patients with a safe and comfortable treatment experience. Summary of the Invention

[0005] In response to the defects existing in the above-mentioned prior art, the present invention aims to provide a ventilator mask that can pass a gastric tube. By adding a structure for connecting a gastric tube to the traditional ventilator mask, the patient's respiratory treatment and nutritional supply can be carried out simultaneously. The gastric tube connection is provided with a clamping and adjustment mechanism and an anti-bending mechanism to clamp, fix and seal the gastric tube inserted on the mask body, and at the same time support the gastric tube above the mask body to prevent the gastric tube from bending or twisting, thereby solving the problems existing in the background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A ventilator mask capable of passing a gastric tube comprises a mask body, the mask body being provided with a passage hole for passing the gastric tube, and further comprising: a guide tube, disposed at the passage hole and having one end extending to the outside of the mask body; The clamping adjustment mechanism is connected to the guide tube and is used to clamp gastric tubes of different diameters and form a sealed wrap around the periphery of the gastric tube; The anti-bending mechanism is movably connected to the top of the clamping and adjusting mechanism to support the gastric tube outside the mask body.

[0007] As a further preferred embodiment of the above technical solution, the clamping adjustment mechanism includes: A screwdriver, rotatably connected to the outer wall of the guide tube; The synchronous tightener is arranged inside the screwdriver, and the two ends of the synchronous tightener are respectively connected to the screwdriver and the guide tube; The clamping member is obliquely arranged in the inner cavity of the guide tube and movably connected to the inner wall of the guide tube, and the synchronous tightener is sleeved on the outside of the clamping member; The rotating ring is movably embedded in the anti-bending mechanism, and the rotating ring is connected to the screwdriver through a telescopic piece.

[0008] In order to better fix the gastric tube passing through the passage hole and prevent the risk of the gastric tube becoming loose due to the patient turning over or moving, the preferred embodiment of the synchronous tightening device includes: An adjusting ring frame, the upper end of which is connected to the inner wall of the screwdriver and the lower end of which is inserted into the longitudinal slot of the guide tube; The air bag is embedded in the inner cavity of the guide tube and is located below the longitudinal slot, and the air bag is communicated with the longitudinal slot.

[0009] A further preferred solution is that the rotating ring is a circular ring structure provided with an internal gear, and cooperates with the anti-bending mechanism through the internal gear.

[0010] As a further preferred embodiment of the above technical solution, the anti-bending mechanism includes: A circular cylinder cover is arranged above the screwdriver and is movably connected to the rotating ring; A plurality of auxiliary clamping parts are located inside the circular cylinder cover and cooperate with the rotating ring; An auxiliary sealing portion is provided on the top of the rotating ring and is located below the plurality of auxiliary clamping portions, each of the auxiliary sealing portions being connected to an end of the auxiliary clamping portion close to the gastric tube; The supporting part is sleeved on the periphery of the gastric tube and is movably connected with each auxiliary clamping part.

[0011] In order to achieve secondary auxiliary clamping of the gastric tube, a further preferred embodiment of the auxiliary clamping parts is that each auxiliary clamping part includes: An auxiliary gear is connected inside the circular cylinder cover and meshes with the internal gear on the rotating ring; The L-shaped clamping rod is arranged in the circular cylinder cover and meshes with the auxiliary gear.

[0012] A further preferred solution is that one end of the L-shaped clamping rod close to the gastric tube is connected to the clamping holder, and the clamping holder is connected to the rubber sealing film on the auxiliary sealing part.

[0013] A further preferred embodiment of the above solution is that the support portion includes: A tube bracket is sleeved on the outer circumference of the gastric tube and connected to the circular tube cover; There are multiple adjusting rods evenly distributed on the outer periphery of the pipe bracket. One end of the adjusting rod is movably connected to the pipe bracket, and the other end is movably connected to the L-shaped clamping rod.

[0014] A further preferred embodiment of the above solution is that the pipe bracket includes: Tube sleeve: a movable sleeve is arranged on the outer periphery of the gastric tube and located above the circular tube cover; A guide rod, which is provided corresponding to the adjusting rod and is movably connected to the pipe sleeve; The connecting ring is connected to the bottom of the pipe sleeve through a guide rod.

[0015] Compared with the prior art, the improvements of the present invention can produce the following beneficial effects: 1. The present invention innovatively opens a channel hole specifically for inserting a gastric tube on the mask body, and cleverly designs a clamping and adjustment mechanism with adjustable aperture in conjunction with this channel hole. The synchronous tightener is fixedly embedded on the inner wall of the screwdriver. When the screwdriver is rotated and moved downward along the guide tube, the adjustment ring frame rotates and moves downward accordingly, causing the gas in the longitudinal groove at the bottom of the adjustment ring frame to be compressed and enter the airbag. After the airbag expands, it tightly wraps around the periphery of the gastric tube to seal it. At the same time, the bottom edge of the mask body closely fits the patient's face, effectively preventing gas leakage. This allows the ventilator to deliver preset gas pressure and tidal volume to the patient, ensuring continuous and efficient respiratory support and meeting the dual therapeutic needs of clinical patients for both breathing and eating.

[0016] 2. The clamping and adjusting mechanism of the present invention can reliably fix gastric tubes of different specifications and diameters. When the adjusting ring frame moves downward with the screwdriver, the upper ring moves downward and contacts the clamping piece, so that the extrusion column on the inner side of the upper ring enters the groove of the clamping piece. The upper end of the clamping piece is pressed and fixed close to the gastric tube by the extrusion column, ensuring that the gastric tube is always in the predetermined position during use, avoiding the risk of displacement or slipping of the gastric tube, and enabling the gastric tube to stably perform functions such as gastrointestinal decompression and nutrient delivery, thereby ensuring the nutritional needs and normal operation of the patient's gastrointestinal system.

[0017] 3. The present invention is provided with an anti-bending mechanism to prevent the gastric tube from being folded. The anti-bending mechanism closely cooperates with the clamping and adjusting mechanism. The anti-bending mechanism includes two aspects of design: one is to provide secondary auxiliary fixation and secondary auxiliary sealing for the gastric tube. By providing an auxiliary clamping portion and an auxiliary sealing portion, the auxiliary clamping portion cooperates with the rotating ring. The rotating ring drives the auxiliary gear to rotate and drive the L-shaped clamping rod close to the gastric tube. The clamping support realizes auxiliary clamping of the outer wall of the gastric tube. At the same time, the L-shaped clamping rod is used to stretch the rubber sealing film so that the rubber sealing film is tightly wrapped around the outer circumference of the gastric tube to provide an auxiliary sealing effect. On the other hand, while the L-shaped clamping rod is moved to clamp the gastric tube, the adjusting rod is rotated by the L-shaped clamping rod, and the angle change of the adjusting rod pushes the tube sleeve to slide upward along the guide rod, thereby increasing the support distance of the tube support on the gastric tube. With the cooperation of the tube support track and the restraint ring, one end of the gastric tube located outside the mask body is effectively supported and guided, avoiding the occurrence of bending or twisting of the gastric tube due to the patient's daily activities, ensuring the smooth delivery of nutrients and smooth gastrointestinal decompression, and reducing additional medical operations and patient discomfort caused by pipeline blockage.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0023] Example 1: Reference Figures 1-9 The present invention provides a ventilator mask that can pass through a gastric tube, comprising a mask body 1. The mask body 1 is made of a soft, skin-friendly material such as multiple layers of silicone or rubber to reduce the sense of oppression on the face and the risk of skin friction damage. A trachea connector 11 connected to the ventilation tube of the ventilator is provided above the mask body 1. A circle of sealing rubber pad is provided at the bottom of the mask body 1. The sealing rubber pad fits tightly against the patient's facial skin to ensure airtightness during treatment. The front end and both sides of the mask body 1 are respectively connected to elastic fixing belts 8 of adjustable length, which cover and fix the mask body 1 to the patient's mouth and nose through the elastic fixing belts 8. Furthermore, a passage hole for passing the gastric tube 5 is opened through the top of the mask body 1, and it also includes a guide tube 2, a clamping and adjusting mechanism 3 and an anti-bending mechanism 4. The guide tube 2 is fixedly connected to the passage hole, and one end of the guide tube 2 extends to the outside of the mask body 1, and the other end extends into the inner cavity of the mask body 1 and extends to the corresponding part of the patient's nasal cavity. The clamping and adjusting mechanism 3 is connected to the guide tube 2, and is used to clamp gastric tubes 5 of different diameters and form a sealed wrap around the outer periphery of the gastric tube 5. The anti-bending mechanism 4 is movably connected to the top of the clamping and adjusting mechanism 3, and is used to support the gastric tube 5 located outside the mask body 1 to prevent this part of the gastric tube 5 from bending.

[0024] like Figure 2 As shown, a tube support track 6 is further provided above the mask body 1, and the two ends of the tube support track 6 are fixedly connected to the two sides of the mask body 1 respectively. A plurality of restraint rings 7 are slidably connected to the tube support track 6, and each restraint ring 7 is magnetically engaged with the tube support track 6. In this embodiment, there are two restraint rings 7. After the gastric tube 5 is passed through each restraint ring 7 respectively, the restraint ring 7 is slid to the appropriate position of the tube support track 6 and the gastric tube 5 is dragged.

[0025] like Figure 4-7 As shown, the clamping and adjusting mechanism 3 includes a screwdriver 31, a synchronous tightener 32, a clamping member 33 and a rotating ring 34. The screwdriver 31 is rotatably connected to the outer wall of the guide tube 2, the synchronous tightener 32 is arranged inside the screwdriver 31, and the two ends of the synchronous tightener 32 are respectively connected to the screwdriver 31 and the guide tube 2. A plurality of clamping members 33 are provided and are all obliquely connected to the inner cavity of the guide tube 2. In this embodiment, there are four clamping members 33, each clamping member 33 is movably connected to the inner wall of the guide tube 2, and the synchronous tightener 32 is sleeved on the outside of the clamping member 33. The rotating ring 34 is movably embedded in the anti-bending mechanism 4, and the rotating ring 34 and the screwdriver 31 are connected by a telescopic member 35.

[0026] In order to prevent the risk of the gastric tube 5 being loosened due to the patient turning over or moving, the gastric tube 5 passing through the channel hole is fixed by a synchronous tightener 32, such as Figure 6As shown, the synchronous tightener 32 includes an adjusting ring frame 321 and an airbag 322. The upper end of the adjusting ring frame 321 is connected to the inner wall of the screwdriver 31. A longitudinal groove 21 is provided on the wall of the guide tube 2. The lower end of the adjusting ring frame 321 is inserted into the longitudinal groove 21. The airbag 322 is embedded in the inner cavity of the guide tube 2, and the airbag 322 is located below the longitudinal groove 21. The airbag 322 is connected to the bottom of the longitudinal groove 21 through a catheter.

[0027] Specifically, the adjusting ring frame 321 includes an upper ring 3211, a lower ring 3212 and a plurality of support rods 3213. Figure 8 As shown, the upper ring 3211 is fixedly embedded in the groove on the inner wall of the screwdriver 31, so the upper ring 3211 rotates simultaneously with the screwdriver 31, and the lower ring 3212 is inserted in the longitudinal groove 21. The lower ring 3212 and the longitudinal groove 21 below it form a closed space, and multiple support rods 3213 are connected between the upper ring 3211 and the lower ring 3212 at intervals. In this embodiment, a total of four support rods 3213 are provided. When the adjustment ring frame 321 moves downward with the screwdriver 31, the lower ring 3212 moves downward in the longitudinal groove 21, so that the gas in the longitudinal groove 21 is squeezed into the air bag 322 below.

[0028] In this embodiment, an extrusion column 323 is provided on the inner side of the upper ring 3211. Figure 8 As shown, the squeezing column 323 corresponds to the position of the groove on the outside of the clamping member 33. When the upper ring 3211 moves downward until the squeezing column 323 contacts the groove, the upper ring 3211 continues to move downward, and the squeezing column 323 squeezes the clamping member 33 toward the direction close to the gastric tube 5, so that the upper end of the clamping frame 33 clamps the outer wall of the gastric tube 5.

[0029] Furthermore, the screwdriver 31 is connected to the outer wall of the guide tube 2 by a threaded connection, a support ring is connected to the inner wall of the guide tube 2, the bottom of the clamping member 33 is hinged to the support ring by a torsion spring, and a rubber pad is provided at the upper end of the clamping member 33, which is connected to the side of the clamping member 33 close to the gastric tube 5. When the upper end of the clamping member 33 contacts the outer wall of the gastric tube 5, the rubber pad helps to increase the friction between the clamping member 33 and the outer wall of the gastric tube 5, thereby achieving a better clamping effect on the gastric tube 5.

[0030] In some preferred embodiments, the rotating ring 34 is a circular structure provided with an internal gear 341, which cooperates with the anti-bending mechanism 4 through the internal gear 341; the telescopic member 35 is located between the screwdriver 31 and the rotating ring 34. In this embodiment, the telescopic member 35 adopts a multi-section nested structure, the top of the telescopic member 35 is connected to the rotating ring 34, and the bottom of the telescopic member 35 is connected to the screwdriver 31. When the screwdriver 31 rotates and moves downward, the telescopic member 35 extends with the distance moved by the screwdriver 31. At the same time, the telescopic member 35 drives the rotating ring 34 to rotate. During the rotation of the rotating ring 34, the anti-bending mechanism 4 better supports the gastric tube 5 above the mask body 1 to prevent the gastric tube 5 from being bent.

[0031] Example 2: On the basis of the above-mentioned embodiment 1, in order to prevent the gastric tube 5 from being bent or twisted due to slight movements of the patient such as turning the head or turning over, the anti-bending mechanism 4 is further improved as follows.

[0032] like Figure 10-14 As shown, the anti-bending mechanism 4 includes a circular cylinder cover 41, multiple auxiliary clamping parts 42, an auxiliary sealing part 43 and a support part 44. The circular cylinder cover 41 is arranged above the screwdriver 31, and a card groove is provided on the inner wall of the circular cylinder cover 41. The rotating ring 34 is movably embedded in the card groove. The multiple auxiliary clamping parts 42 are all located inside the circular cylinder cover 41 and cooperate with the rotating ring 34. The auxiliary sealing part 43 is arranged at the top of the rotating ring 34, and the auxiliary sealing part 43 is located below the multiple auxiliary clamping parts 42. In this embodiment, there are four auxiliary clamping parts 42, each auxiliary sealing part 43 is connected to the end of the auxiliary clamping part 42 close to the gastric tube 5, and the support part 44 is sleeved on the outer periphery of the gastric tube 5 and movably connected to each auxiliary clamping part 42.

[0033] In this embodiment, while supporting the gastric tube 5, the gastric tube 5 is clamped for a second time, such as Figure 10 、 Figure 12 As shown, each auxiliary clamping part 42 includes an auxiliary gear 421 and an L-shaped clamping rod 422. The auxiliary gear 421 is connected to the circular cylinder cover 41, and the auxiliary gear 421 is engaged with the internal gear 341 on the rotating ring 34. The L-shaped clamping rod 422 is arranged in the circular cylinder cover 41. The L-shaped clamping rod 422 is engaged with the auxiliary gear 421. When the rotating ring 34 rotates, the auxiliary gear 421 is driven to rotate by the internal gear 341. The auxiliary gear 421 cooperates with the rack on one side of the L-shaped clamping rod 422. The rotation of the auxiliary gear 421 drives the L-shaped clamping rod 422 to move horizontally close to the gastric tube 5 to achieve clamping.

[0034] like Figure 12As shown, the auxiliary sealing portion 43 includes a mounting ring 431 and a rubber sealing film 432. The mounting ring 431 is arranged on the top of the screwdriver 31 and is fixedly connected to the circular cylinder cover 41. The rubber sealing film 432 is fixedly connected to the inner side of the mounting ring 431. The end of the L-shaped clamping rod 422 close to the gastric tube 5 is connected to the clamping support 423. The bottom of the clamping support 423 is connected to the free end edge of the rubber sealing film 432. When the L-shaped clamping rod 422 moves toward the gastric tube 5, the clamping support 423 contacts the outer wall of the gastric tube 5 and clamps it, and the clamping support 423 drives the rubber sealing film 432 to circumferentially surround the outer wall of the gastric tube 5 to form an auxiliary sealing effect.

[0035] like Figure 11 As shown, the support portion 44 includes a tube bracket 441 and an adjusting rod 442. The tube bracket 441 is sleeved on the outer periphery of the gastric tube 5 and connected to the circular tube cover 41. There are multiple adjusting rods 442, and the multiple adjusting rods 442 are evenly distributed on the outer periphery of the tube bracket 441. There are four adjusting rods 442 in this embodiment, and one end of each adjusting rod 442 is movably connected to the tube bracket 441. The top cover of the circular tube cover 41 is provided with multiple through slots, each of which corresponds to the position of each L-shaped clamping rod 422. The other end of the adjusting rod 442 is movably connected to the L-shaped clamping rod 422 through the through slot.

[0036] like Figure 14 As shown, the tube bracket 441 includes a tube sleeve 4411, a guide rod 4412 and a connecting ring 4413. The tube sleeve 4411 is movably mounted on the outer periphery of the gastric tube 5, and the tube sleeve 4411 is located above the circular tube cover 41. The guide rod 4412 is correspondingly arranged to the adjustment rod 442. The guide rod 4412 is movably connected to the outside of the sleeve. The connecting ring 4413 is located below the tube sleeve 4411 and is connected to the sleeve through the guide rod 4412.

[0037] When the L-shaped clamping rod 422 moves in the direction close to the gastric tube 5, the lower end of the adjusting rod 442 rotates counterclockwise as the L-shaped clamping rod 422 moves, thereby causing the upper end of the adjusting rod 442 to move upward, and the adjusting rod 442 pushes the tube sleeve 4411 to move upward along the guide rod 4412, so that the tube sleeve 4411 can form a longer distance support for the gastric tube 5 and be more stretched, thereby avoiding the gastric tube 5 from bending due to the patient's turning over and other actions.

[0038] Example 3: A ventilator mask that can pass through a gastric tube, in actual clinical application: First, put the mask body 1 on the patient's face so that the mask body 1 fully covers the patient's mouth and nose. Fix the mask body 1 on the patient's face by adjusting the tightness of the elastic fixing belt 8 so that the sealing pad at the bottom of the mask body 1 is completely sealed with the patient's facial skin. Then, the front end of the gastric tube 5 is inserted into the guide tube 2 through the passage hole, and then enters the patient's nasal cavity through the guide tube 2 and extends into the interior. The other end of the gastric tube 5 is passed through the restraining ring 7 and fixed on the tube support track 6. Next, the screwdriver 31 is rotated clockwise, and moves downward along the outer wall of the guide tube 2. The upper ring 3211 rotates and moves downward synchronously with the screwdriver 31, and the lower ring 3212 rotates and moves downward in the longitudinal slot 21, so that the gas in the longitudinal slot 21 below the lower ring 3212 is squeezed into the airbag 322. After the airbag 322 expands, it surrounds the circumference of the gastric tube 5 to form a sealing effect. At the same time, when the upper ring 3211 moves downward, it squeezes the clamping rod so that its upper end contacts the gastric tube 5. The gastric tube 5 is clamped circumferentially by multiple clamping rods to prevent the gastric tube 5 from moving around and adversely affecting the patient's normal nutrition supply. As the screwdriver 31 rotates and moves downward, the rotating ring 34 rotates synchronously clockwise. The internal gear 341 on the rotating ring 34 engages with the auxiliary gear 421, driving the auxiliary gear 421 to rotate clockwise. When the auxiliary gear 421 rotates, it pushes the L-shaped clamping rod 422 toward the gastric tube 5, and the clamping support 423 performs a secondary auxiliary clamping on the gastric tube 5. At the same time, the clamping support 423 drives the rubber sealing film 432 to surround the outer circumference of the gastric tube 5 to achieve auxiliary sealing, further strengthening the clamping and sealing effect of the gastric tube 5. When the L-shaped clamping rod 422 approaches the gastric tube 5, it simultaneously drives the lower end of the adjusting rod 442 to move, causing the adjusting rod 442 to rotate counterclockwise, thereby causing the upper end of the adjusting rod 442 to move upward. The adjusting rod 442 pushes the tube sleeve 4411 to move upward along the guide rod 4412 around the outer circumference of the gastric tube 5, thereby increasing the support distance of the gastric tube 5 and making the part of the gastric tube 5 above the mask body 1 more stretched, effectively preventing the gastric tube 5 from being bent or twisted due to the patient turning or turning over. After the gastric tube 5 is placed and clamped, the ventilation tube of the ventilator is connected to the trachea connector 11 above the mask body 1, and the ventilator is turned on for normal operation.
