Description

Technical Field

[0001] The utility model relates to the technical field of breathing masks, in particular to an anti-falling breathing mask for critically ill patients. Background Art

[0002] Some critically ill patients in the respiratory department have difficulty breathing on their own and need to be assisted in breathing by a pressurized air-oxygen mixture delivered by a non-invasive ventilator. The ventilator ventilates the patient's mouth and nose through a ventilation tube and a breathing mask. The breathing mask is fixed to the patient's head with an elastic fixing strap. The length of the elastic fixing strap is adjusted according to the patient's head circumference. The fixing property of the mask is relatively strong, but it still has the problem of falling off during clinical use.

[0003] Although the breathing mask can be fixed on the patient's head through an elastic fixing strap, some patients have a long treatment cycle and need to wear the breathing mask for a long time. Due to the large size of the front end of the breathing mask, the patient is prone to touch the bed or pillow when turning sideways on the bed, causing the oxygen mask to fall off and loosen, which in turn causes the breathing mask to misalign with the mouth and nose. The air-oxygen mixed gas provided by the ventilator overflows from the side of the breathing mask, which is not conducive to the treatment of patients and also wastes medical supplies. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a breathing mask for critically ill patients that is prevented from falling off.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A breathing mask for critically ill patients that prevents them from falling off comprises a mask body, wherein the mask body comprises a facial mask body that fits the patient's mouth and nose and a duct mask body that protrudes outward, wherein the central bulge of the facial mask body forms a convex structure that fits the face, the duct mask body is stacked on the convex surface of the convex structure of the facial mask body, the convex surface of the convex structure is provided with a transverse slide groove, both ends of the slide groove are provided with elastic components, a slider is slidably connected in the slide groove, the back side of the duct mask body is fixedly connected to the slider, the lower end of the facial mask body is provided with a ventilator ventilation pipe through hole corresponding to the ventilator ventilation pipe joint of the duct mask body, and the ventilator ventilation pipe through hole is connected to the ventilator ventilation pipe joint through a connecting hose.

[0007] Furthermore, the back of the catheter cover body has the same raised structure as the facial cover body, and the slider is connected to the back of the catheter cover body through a connecting portion extending outward. The middle of the facial cover body is slightly convex outward, and a storage space for accommodating the nasal cavity and mouth is formed on the back of the facial cover body. Since the facial cover body is a raised structure, in order to ensure the fitting effect between the catheter cover body and the facial cover body, the structure of the catheter cover body is the same as that of the facial cover body and is also a raised structure. The slider is limited to sliding in the slide groove, and the slider is fixedly connected to the catheter cover body through the connecting portion.

[0008] Furthermore, two sliders are arranged in the slide groove, and the two sliders are respectively connected to the free ends of the two elastic components. The elastic components are springs, and their function is to restore the catheter cover body to the middle of the facial cover body when the external force is lost. Both sliders are connected to the back of the catheter cover body, which can maintain better stability.

[0009] Furthermore, the slide grooves include two, both of which are located above the ventilation pipe through hole of the ventilator. The two slide grooves also play a role in improving stability and stabilizing effect. When the catheter cover moves left and right, the two slide grooves can ensure that the catheter cover will not deviate or move in the up and down directions.

[0010] Furthermore, the channel of the slide groove is adapted to the raised structure of the face mask. The slide groove is an arc-shaped structure, and when the catheter mask is subjected to external force, the catheter mask rotates along the arc direction of the slide groove, that is, it deviates left and right around the wearer's face.

[0011] Furthermore, the connecting hose is a folding bellows. When the catheter cover is displaced, the folding bellows can ensure that the oxygen passage is not affected, so that the air-oxygen mixed gas is normally supplied. The two ends of the folding bellows are fixedly connected to the face cover and the catheter cover, so as to avoid the plug-in pipeline from being dislocated due to the relative displacement of the face cover and the catheter cover and causing the pipe to fall off.

[0012] Further, the facial mask body is provided with a fixing assembly for connecting a head elastic band. Through the head elastic band, the facial mask body can be worn on the patient's head, and the fixing of patients with different head circumferences can be achieved by adjusting the tightness.

[0013] Furthermore, the fixing assembly includes two sets of correspondingly arranged mounting buckles, which are respectively arranged at the upper part and the middle part of the face mask body. After the head elastic band is fastened to the mounting buckles, the two head elastic bands are respectively worn at the back of the head and the back of the neck to achieve a stable fixing effect.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model provides a separate facial mask body and catheter mask body to ensure that the mask will not loosen or fall off due to the rotation of the head when the patient lies down, thereby ensuring the treatment effect of the patient;

[0016] 2. The utility model can adjust the position of the catheter cover body laterally according to the patient's facial position, so as to avoid the protrusion affecting the patient's body position change and improve the adaptability of the patient to multiple body positions;

[0017] 3. The utility model avoids oxygen overflow and waste of medical consumables, while reducing the workload of medical staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0023] Embodiment 1

[0024] like Figure 1-3 As shown, the utility model discloses an anti-detachment breathing mask for critically ill patients, comprising a mask body, wherein the mask body comprises a facial mask body 1 fitted at the patient's mouth and nose and a duct mask body 2 protruding outward, the central bulge of the facial mask body 1 forms a convex structure fitted with the face, the duct mask body 2 is stacked on the convex surface of the convex structure of the facial mask body 1, the convex surface of the convex structure is provided with a transverse slide groove 3, both ends of the slideway of the slide groove 3 are provided with an elastic component 4, a slider 5 is slidably connected in the slide groove 3, the back side of the duct mask body 2 is fixedly connected to the slider 5, the lower end of the facial mask body 1 is provided with a ventilator ventilation pipe through hole 7 corresponding to the ventilator ventilation pipe connector 6 of the duct mask body 2, and the ventilator ventilation pipe through hole 7 is connected to the ventilator ventilation pipe connector 6 through a connecting hose 8.

[0025] The back of the catheter cover body 2 has the same raised structure as the facial cover body 1, and the slider 5 is connected to the back of the catheter cover body 2 through a connecting portion extending outward. Specifically, the middle portion of the facial cover body 1 is slightly convex outward, and a storage space for accommodating the nasal cavity and mouth is formed on the back of the facial cover body 1. Since the facial cover body 1 is a raised structure, in order to ensure the fitting effect between the catheter cover body 2 and the facial cover body 1, the structure of the catheter cover body 2 is the same as that of the facial cover body 1 and is also a raised structure. The slider 5 is limited to sliding in the slide groove 3, and the slider 5 is fixedly connected to the catheter cover body 2 through a connecting portion. When the catheter cover body 2 is adjusted to the left or right, the catheter cover body 2 will drive the slider 5 to move left and right.

[0026] Two sliders 5 are arranged in the slide groove 3, and the two sliders 5 are respectively connected to the free ends of the two elastic components 4. Specifically, the elastic component 4 is a spring, and the spring here is a spring with low elastic potential energy. The function is that when the external force is lost, the catheter cover body 2 will return to the middle of the facial cover body 1. The two sliders 5 are connected to the back of the catheter cover body 2, which can maintain better stability.

[0027] The two slide grooves 3 are both located above the ventilator ventilator through hole 7. Specifically, the two slide grooves 3 also play a role in improving stability and stabilizing effect. When the catheter cover body 2 moves left and right, the two slide grooves 3 can ensure that the catheter cover body 2 will not deviate or move in the up and down directions.

[0028] The channel of the slide groove 3 is adapted to the convex structure of the face mask 1. Specifically, the slide groove 3 is an arc structure, and when the catheter mask 2 is subjected to external force, the catheter mask 2 rotates along the arc direction of the slide groove 3, that is, it deviates left and right around the wearer's face.

[0029] The connecting hose 8 is a folding bellows. Specifically, when the catheter cover 2 is displaced, the folding bellows can ensure that the oxygen passage is not affected, so that the air-oxygen mixed gas is normally supplied. The two ends of the folding bellows are fixedly connected to the face cover 1 and the catheter cover 2 to prevent the plug-in pipeline from being dislocated due to the relative displacement of the face cover 1 and the catheter cover 2 and causing the pipe to fall off.

[0030] The facial mask 1 is provided with a fixing assembly for connecting the head elastic band. Specifically, the facial mask 1 can be worn on the patient's head through the head elastic band, and the fixation of patients with different head circumferences can be achieved by adjusting the tightness.

[0031] The fixing assembly includes two sets of correspondingly arranged mounting buckles 9, which are respectively arranged at the upper part and the middle part of the face mask body 1. Specifically, after the head elastic band is tied to the mounting buckle 9, the two head elastic bands are respectively worn at the back of the head and the back of the neck to achieve a stable fixing effect.

[0032] In addition, an oxygen inhalation hole and a one-way valve are provided on the catheter mask body 2, and both the oxygen inhalation hole and the one-way valve are connected to the facial mask body 1 through a folded hose. The oxygen inhalation hole includes a pressure monitoring hole, which is usually closed and is used for oxygen inhalation and pressurization, and can also be used for atomization, external treatment gas or pressure monitoring. The function of the one-way valve is to prevent the patient from suffocating in the closed facial mask body 1.

[0033] Embodiment 2

[0034] Based on the first embodiment, this embodiment proposes a specific implementation process of preventing critically ill patients from removing their breathing masks.

[0035] The specific implementation principle process is as follows:

[0036] First, connect the external non-invasive ventilator to the ventilator ventilation pipe connector 6, and wear the head elastic band at the same time, and adjust the tightness to achieve a fixing effect. Turn on the non-invasive ventilator, and the mixed gas is delivered to the patient's mouth and nose through the ventilator ventilation pipe connector 6, the connecting hose 8 and the ventilator ventilation pipe through hole 7 in sequence.

[0037] For some patients with longer treatment cycles, when they are resting in bed, the protruding length of the catheter cover body 2 and the ventilator ventilation tube connector 6 is relatively long, and they are easily in contact with the bed or pillow during the sideways turning on the bed, which may cause the mask to be misaligned or loosened against the mouth and nose, causing gas to overflow.

[0038] In the present application, when the patient turns sideways, the external resistance can cause the catheter cover 2 to slide along the slide groove 3 and deviate, while the facial cover 1 always fits the patient's face, so there will be no oxygen leakage. If the patient returns to a lying position from a side-lying position, the catheter cover 2 loses the external force, the elastic component 4 restores its elastic deformation, and the catheter cover 2 returns to the center of the facial cover 1, and the oxygen supply function is not affected.

[0039] Of course, the present invention may have many other implementation modes. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
