[0035] In the related technology, nasal oxygen cannula and pressure relief patch are two kinds of auxiliary treatment devices often used in clinical medicine. Nasal oxygen cannula is a medical device used to deliver oxygen to patients. It is usually made of soft plastic and is divided into bilateral nasal plug type or unilateral nasal catheter type. One end of the nasal oxygen cannula is connected to an oxygen supply device, such as an oxygen cylinder or a central oxygen supply system, and the other end has two or one nasal plug, which is directly inserted into the patient's nasal cavity to continuously and stably deliver oxygen to the patient. It is especially suitable for patients with respiratory diseases who need oxygen therapy, patients in the postoperative recovery period, and patients who need to maintain oxygenation levels after cardiac arrest resuscitation. Pressure relief patch is a protective device used when using oxygen therapy to avoid compression damage to the skin of the hands and face caused by excessive oxygen pressure. When high-flow oxygen acts directly on the facial skin through the nasal oxygen cannula for a long time, the skin may be damaged due to excessive local pressure, resulting in pain, redness, swelling, and even pressure sores.

[0036] Clinically, the areas that are prone to pressure injuries when using nasal oxygen cannulas include behind the ears and on the face. Usually, gauze pads are placed behind the ears or hydrocolloid dressings are applied to the compressed skin of the patient to reduce pressure. However, the above measures cannot fully reduce the pressure on the skin.

[0037] like Figure 1 and Figure 2As shown, in order to solve the above technical problems, an embodiment of the present application provides a decompression patch, which includes a soft pad 100 and a plurality of elastic thin plates 200, wherein the soft pad 100 has a first direction and a second direction, and the first direction and the second direction are perpendicular to each other; the plurality of elastic thin plates 200 are connected to the soft pad 100, and the plurality of elastic thin plates 200 are arranged at intervals along the first direction, and the elastic thin plates 200 are extended along the second direction; wherein, in an initial state, the soft pad 100 and the elastic thin plates 200 are bent on the same side to form a pipe passage 110, and the pipe passage 110 is for pipes or cables to pass through.

[0038] In this embodiment, a nasal oxygen tube is installed in the tube insertion channel 110 as an example. Of course, it is not limited to this one. Others may also be oxygen tubes, gastric tube cotton threads, ECG monitoring electrode lines, drainage tubes, etc., which are not specifically limited here.

[0039] That is, after the nasal oxygen tube is inserted into the tube insertion channel 110, the soft cushion 100 and the elastic sheet 200 are located between the nasal oxygen tube and the compressed skin.

[0040] For example, the elastic sheet 200 is located in the middle or inner side of the cushion 100, that is, the elastic sheet 200 contacts the compressed skin through the cushion 100. The cushion 100 forms a primary decompression; the elastic sheet 200 has a certain rigidity, can play a role of skeleton support, increase the contact area with the compressed skin, and form a secondary decompression.

[0041] It should be noted that, in some embodiments, the cushion 100 is located on the outside of the elastic sheet 200 so as to be able to contact the compressed skin, and the contact area of ​​the elastic sheet 200 can be increased by deformation of the cushion 100, thereby improving comfort.

[0042] In addition, since the multiple elastic thin plates 200 are arranged in sequence in the extension direction of the nasal oxygen tube, the portion of the soft cushion 100 located between adjacent elastic thin plates 200 can be deformed more easily, so that the tube insertion channel 110 can conform to the curvature of the nasal oxygen tube, improve the fit between the decompression point and the compressed skin, increase the contact area of ​​the decompression patch contacting the compressed skin, and avoid insufficient decompression due to the formation of wrinkles.

[0043] By using the decompression patch provided by the utility model, an elastic thin plate 200 is added on the soft cushion 100. The elastic deformation of the elastic thin plate 200 can increase the stress-bearing area of ​​the skin, and the pressure is fully reduced, instead of relying solely on the soft cushion 100 for decompression. In addition, since a plurality of elastic thin plates 200 are arranged at intervals, the bendability of the tube penetration channel 110 can be improved, so as to ensure the fit between the tube penetration channel 110 and the skin on the basis of increasing the stress-bearing area through the elastic thin plate 200, meet the skin's compliance requirements, further increase the stress-bearing area of ​​the skin, and reduce damage to the compressed skin.

[0044] In other words, the decompression patch is attached to the position where the nasal oxygen tube contacts the skin. Its main function is to disperse and relieve the pressure of the oxygen tube on the facial skin, protect the skin from damage, and increase the comfort of the patient. In summary, the clinical use of nasal oxygen tubes and decompression patches can not only ensure that patients can receive adequate oxygen treatment, but also minimize the risk of potential complications and improve the quality of care.

[0045] like Figure 2 As shown, in some embodiments, the soft pad 100 is provided with a plurality of groups of easy-tear holes 410, and the portion of the soft pad 100 located between adjacent elastic sheets 200 has at least one group of easy-tear holes 410; wherein the group of easy-tear holes 410 includes a plurality of easy-tear holes 410, and the plurality of easy-tear holes 410 in the same group are at least partially arranged at intervals along the second direction and form a tear line 400.

[0046] Obviously, by tearing along the tear line 400, medical personnel can tear off the cushion 100 of corresponding length according to the length of the nasal oxygen tube contacting the skin, which is convenient to use.

[0047] Of course, by providing the group of easy-tear holes 410, the air permeability of the pressure relief patch can be increased, thereby improving the comfort of the user.

[0048] It should be noted that, since the tear line 400 is arranged to extend along the circumference of the nasal oxygen tube, in actual use, when the curvature of the nasal oxygen tube is too large, the two ends of the tear line 400 can be torn open, but not completely to meet the compliance requirements of the nasal oxygen tube, thereby improving the bending deformation ability of the pressure relief patch, increasing the contact area between the pressure relief patch and the compressed skin, and enhancing the pressure relief ability.

[0049] In some embodiments, the portion of the cushion 100 located on the elastic sheet 200 has an easy-tear hole 410 , and the easy-tear hole 410 passes through the elastic sheet 200 .

[0050] That is to say, on the basis of the above embodiment, in order to improve the air permeability of the decompression patch, the portion of the soft pad 100 located on the elastic sheet 200 is also provided with an easy-tear hole 410. Obviously, since the elastic sheet 200 is provided with the easy-tear hole 410, the elasticity of the elastic sheet 200 can also be improved, which is conducive to further increasing the contact area between the decompression patch and the compressed skin.

[0051] For example, the elastic sheet 200 is a plastic sheet, which is convenient for subsequent punching of the easy-tear holes 410. When punching, the easy-tear holes 410 can be punched by a punching process after the elastic sheet 200 is fixed to the cushion 100.

[0052] like Figure 1 and Figure 3As shown, in some embodiments, the decompression patch also includes a connector 500, which can connect the two ends of the cushion 100 in the second direction; wherein, the cushion 100 has a gap 120 between the two ends in the second direction, and at least one of the two ends of the cushion 100 in the second direction is detachably connected to the connector 500.

[0053] In actual use, after inserting the pipe or cable into the pipe-through hole 110, the pipe-through hole 110 is tightened by the connector 500, thereby clamping and fixing the pipe or cable through the pipe-through hole 110 instead of gluing. It is suitable for pipes or cables that cannot be fixed by gluing, such as ECG monitoring electrode lines.

[0054] Among them, since the cushion 100 has the gap 120 in the second direction, it is convenient to insert the pipeline or cable into the pipe passage 110 through the gap 120, thereby improving the convenience of operation.

[0055] It should be noted that, since the cushion 100 has the gap 120 in the second direction, the aperture of the pipe passage 110 can be changed through elastic deformation, so that it is suitable for pipes or cables of different diameters and has a wide range of applications.

[0056] like Figure 1 As shown, in some embodiments, both ends of the cushion 100 in the second direction are detachably connected to the connecting member 500; wherein the connecting member 500 includes a plurality of adhesive tapes, the adhesive tapes have a pair of first adhesive portions 510, the first adhesive portions 510 have a first release paper, and the pair of first adhesive portions 510 are respectively bonded to the two ends of the cushion 100 in the second direction.

[0057] That is, after tearing off the first release paper on the pair of first adhesive portions 510, the pair of first adhesive portions 510 are respectively bonded to the two ends of the cushion 100 in the second direction to seal the gap 120. In addition, the aperture of the tube passage 110 can be adjusted by changing the position of the first adhesive portion 510.

[0058] Of course, if Figure 1 As shown, in some embodiments, the first adhesive portion 510 is provided on only one end of the adhesive tape, and the end of the adhesive tape without the first adhesive portion 510 is fixed to one end of the cushion 100 in the second direction. The end of the adhesive tape with the first adhesive portion 510 can be bonded to the other end of the cushion 100 in the second direction after the first release paper is torn off. The aperture of the tube passage 110 can be adjusted by adjusting the bonding position of the first adhesive portion 510.

[0059] like Figure 1 and Figure 2As shown, in some embodiments, the cushion 100 has identification portions 300 at both ends in the second direction, and when a pair of first adhesive portions 510 are respectively connected to the two ends of the cushion 100 in the second direction, the pair of identification portions 300 are located in a preset plane, and the preset plane is arranged parallel to the second direction.

[0060] That is to say, by respectively providing identification portions 300 at both ends of the cushion 100, the identification portions 300 are used to calibrate the bonding positions of a pair of first bonding portions 510 so that the bonding positions of a pair of first bonding portions 510 are located on the same cross-section of the tube passage 110, thereby avoiding axial misalignment of the pair of first bonding portions 510 in the tube passage 110, thereby avoiding insufficient decompression due to the appearance of wrinkles.

[0061] Exemplarily, the identification portion 300 includes dyed areas disposed at both ends of the cushion 100 in the second direction, the dyed areas at both ends of the cushion 100 in the second direction have the same color, and the dyed areas at both ends of the cushion 100 in the second direction are located on the same straight line parallel to the second direction.

[0062] Illustratively, the identification portion 300 is disposed on a portion of the cushion 100 to which the elastic sheet 200 is fixed.

[0063] For example, the color of the dyed area is red. Of course, in other embodiments, it can also be set to yellow, blue or green, etc., which is not specifically limited here.

[0064] like Figure 2 As shown, in some embodiments, a second adhesive portion 600 is provided on a side of the cushion 100 facing the tube passage 110 , and the second adhesive portion 600 has a second release paper.

[0065] Obviously, tearing off the second release paper can expose the second adhesive portion 600, and can bond and fix the pipe or cable passing through the pipe passage 110. It should be noted that this structure is only used for some pipes or cables that can be glued, such as disposable oxygen tubes, nasal oxygen tubes, etc.

[0066] Exemplarily, the second bonding portion 600 is arranged to extend along the second direction, thereby increasing the bonding area between the second bonding portion 600 and the pipe or cable.

[0067] like Figure 2 As shown, in some embodiments, the second adhesive portion 600 includes a double-sided adhesive sticker, and the double-sided adhesive sticker is adhered to the cushion 100 .

[0068] One end of the double-sided adhesive tape is pre-adhesively fixed to the inner wall of the pipe passage 110, and the other end of the double-sided adhesive tape retains the release paper.

[0069] Obviously, through the cooperation of the second adhesive part 600 and the connecting part 500, a variety of fixing methods can be achieved, for example, the pipeline or cable is fixed only by the connecting part 500; or, the pipeline or cable is fixed only by the second adhesive part 600; or the second adhesive part 600 and the connecting part 500 are used simultaneously to fix the pipeline or cable, which is not specifically limited here.

[0070] like Figure 1 As shown, in some embodiments, the thickness of the cushion 100 is thick in the middle and thin at both ends in the second direction.

[0071] Obviously, the cushion 100 is arranged to be thinner at both ends of the second direction, which is beneficial to controlling the elastic deformation of the pipe-through hole 110 and further changing the aperture of the pipe-through hole 110 .

[0072] In some embodiments, the thickness of the elastic thin plate 200 in the second direction is thick in the middle and thin at both ends.

[0073] Similarly, by setting the two ends of the elastic sheet 200 in the second direction to be thinner, the elastic deformation capacity of the two ends can be improved, and the elastic deformation of the pipe passage 110 can be further controlled.

[0074] like Figure 1 As shown, in some embodiments, the elastic sheet 200 is disposed inside the cushion 100 .

[0075] The elastic sheet 200 and the cushion 100 are arranged in parallel, so that the part of the cushion 100 located on the outside of the elastic sheet 200 can be used to increase the contact area between the elastic sheet 200 and the skin, and the part of the cushion 100 located on the inside of the elastic sheet 200 can be used to increase the contact area between the pipeline or cable and the elastic sheet 200, thereby dispersing the pressure of the pipeline or cable and improving the decompression effect.

[0076] For example, the soft pad 100 is made of polyurethane foam. Optionally, the soft pad 100 includes two polyurethane foam sheets, the elastic sheet 200 is placed between the two polyurethane foam sheets and fixed by bonding, and then the easy-tear holes 410 are punched. Of course, the soft pad 100 can also be made of other materials, such as rubber pads, silicone pads, etc., as long as they can achieve the same function, and are not specifically limited here.

[0077] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0078] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0079] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
