Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a respirator mask decompression pad. Background Art

[0002] As an effective means of artificially replacing the spontaneous ventilation function, the ventilator has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation. It occupies a very important position in the field of modern medicine. The breathing mask is an important part in the use of the ventilator. It fits the human face to facilitate the entry of gas.

[0003] In the prior art, a Chinese patent with publication number "CN216798439U" discloses a non-invasive ventilator mask decompression pad. By setting a buffer mechanism, when squeezed, the connecting plate slides in the installation groove for guidance, and the first return spring buffers to reduce pressure, thereby avoiding squeezing to cause deep indentations or injure the skin, and increasing the comfort of use. By setting a first circular hole, a second circular hole, a cavity, etc., the first circular hole cooperates with the second circular hole for ventilation, so that the contact point between the lower rubber pad and the skin will not be excessively stuffy, which solves the problem that when the existing ventilator mask is covered on the patient's face with an elastic rope, the mask is pressed tightly against the patient's face, and after a long time, a deep indentation will be left on the patient's face, affecting the comfort of use of the device.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] During use, the existing breathing mask is sealed only by a rubber ring, and lacks a decompression pad. Long-term use can easily lead to deep indentations, affecting the comfort of use of the device. In the solution described above, the elastic performance of the return spring is used to reduce the pressure between the mask and the patient's face. Due to the long-term contact between the rubber and the patient's face, the rubber will damage the patient's skin, which will cause damage to the patient's face. In addition, the decompression pad on the ventilator mask is exposed to the outside world for a long time. Due to external factors, the decompression point may be damaged, which seriously affects the practicability of the ventilator mask decompression pad. Utility Model Content

[0031] The pressure relief pad body 3 is provided with a skin-friendly layer 31, a foam absorption pad 32 and a semi-permeable waterproof film 33 in sequence from the outside to the inside. The skin-friendly layer 31 is composed of graphene fibers 311 and cellulose fibers 312. The graphene fibers 311 are located on the outside of the cellulose fibers 312. The graphene fibers 311 and the fibers enhance the comfort between the pressure relief pad body 3 and the skin.

[0032] In this embodiment, the skin-friendly layer 31 in the pressure-reducing pad body 3 can reduce the pressure on the patient's face when using a non-invasive ventilator, that is, it can reduce the edema and blood circulation problems caused by long-term pressure on the face. The foam absorption pad 32 can reduce the pressure on the patient's face caused by the ventilator mask body 1, and then the semi-permeable waterproof film 33 is used to absorb the moisture in the ventilator mask body 1, thereby effectively improving the practicality of the pressure-reducing pad on the ventilator mask.

[0033] Embodiment 2:

[0034] On the basis of the first embodiment, in order to prevent the pressure relief pad body 3 from being in the outside world for a long time when not in use and being damaged by external factors, a storage component is used to avoid this phenomenon. The storage component includes a storage groove 4 and a sealing patch 5 arranged on the rubber pad 2. The sealing patch 5 and the rubber pad 2 are both provided with adhesive. The adhesive is a technology well known to people in the field. The adhesive will not cause damage to the patient's face. At the same time, the adhesive is a means of fixing the sealing patch 5 on the rubber pad 2. In addition to this method, threaded holes can also be set on the sealing patch 5 and the rubber pad 2 to tighten It is also possible to fix it with a fixed bolt, and the installation groove is sealed by a sealing patch 5 and an adhesive. A return spring 6 is fixedly installed at the inner bottom of the storage groove 4. The number of the return springs 6 is multiple and evenly distributed in the storage groove 4, ensuring that the telescopic plate 7 can move normally, and also ensuring that the telescopic plate 7 is uniformly acted upon by the elastic force when displacement occurs. The telescopic plate 7 is fixedly installed at one end of the return spring 6 away from the storage groove 4, and the position of the telescopic plate 7 is inside the storage groove 4. The decompression pad body 3 is installed on the telescopic plate 7, and the decompression pad body 3 is conveniently stored through the storage groove 4;

[0035] A limiting slider 8 is fixedly installed on the telescopic plate 7, and a limiting slide groove 9 used in conjunction with the limiting slider 8 is opened inside the storage groove 4. There are two limiting sliders 8, and the two limiting sliders 8 are symmetrically arranged on the telescopic plate 7. The two limiting sliders 8 slide in the two limiting slide grooves 9, so that the telescopic plate 7 is more stable when sliding. The limiting slider 8 slides in the limiting slide groove 9, which ensures the stability of the pressure relief pad body 3 when moving, and also prevents the pressure relief pad body 3 from falling off from the mounting groove.

[0036] In this embodiment, by tearing off the sealing patch 5 from the rubber pad 2, the pressure relief pad body 3 will pop out from the mounting groove through the action of the reset spring 6. At the same time, the sealing patch 5 is used to seal the mounting groove on the rubber pad 2, so that the pressure relief pad body 3 can be stored and hidden when not in use, thereby preventing the pressure relief pad body 3 from being exposed to the outside world and being damaged, thereby further improving the practicality of the pressure relief pad.

[0037] Working principle:

[0038] By tearing off the sealing patch 5 from the rubber pad 2, the pressure relief pad body 3 installed on the telescopic plate 7 pops out from the mounting groove by the action of the reset spring 6. When the telescopic plate 7 is displaced, the limiting slider 8 on the telescopic plate 7 will slide within the limiting slide groove 9 in the mounting groove. The limiting slider 8 slides within the limiting slide groove 9, thereby ensuring the stability of the pressure relief pad body 3 during movement and preventing the pressure relief pad body 3 from falling off from the mounting groove. At the same time, the sealing patch 5 is used to seal the mounting groove on the rubber pad 2, so that the pressure relief pad body 3 can be stored and hidden when not in use, thereby preventing the pressure relief pad body 3 from being damaged by the outside world due to the outside world.

[0039] The skin-friendly layer 31 in the pressure-reducing pad body 3 can reduce the pressure on the patient's face when using a non-invasive ventilator, that is, it can reduce the problems of edema and blood circulation obstruction caused by long-term facial pressure. The foam absorption pad 32 can reduce the pressure on the patient's face caused by the ventilator mask body 1, and then the semi-permeable waterproof film 33 is used to absorb the moisture in the ventilator mask body 1, thereby effectively improving the practicality of the pressure-reducing pad on the ventilator mask.
