Description

Technical Field

[0001] The invention relates to the technical field of tracheotomy care, in particular to a protective device for showering after tracheotomy patients. Background Art

[0002] Head and neck surgery is an extended discipline of otolaryngology. It has gradually developed to meet the needs of clinical diagnosis and treatment and scientific research of head and neck and otolaryngology-related malignant tumors. Head and neck surgical diseases can be divided into many types according to the time, location and nature of onset. In the treatment of head and neck surgical diseases, tracheotomy is a method of cutting the cervical trachea and inserting a metal tracheal tube and a silicone tube. It is a common operation to relieve laryngeal dyspnea, respiratory dysfunction or dyspnea caused by retention of lower respiratory tract secretions.

[0003] After tracheotomy, patients do not breathe through the mouth and nose, but through a tracheotomy protective device, which allows patients to avoid water entering the tracheotomy when showering, preventing infection and other complications. In order to ensure that the patient breathes normally, a tracheal tube needs to be installed on the protective device to provide the patient with short-term assisted ventilation.

[0004] Application No. CN202222780556.X discloses a tracheotomy care device that is easy to fix, including a protective plate and a retraction mechanism arranged inside the protective plate. The retraction mechanism includes a rotating component, a connecting component and a retraction component. Through the synchronous relative sliding of two sets of straps, the tightness of the straps can be adjusted to prevent the straps from being too tight and causing difficulty in breathing for the patient.

[0005] When using the tracheotomy care device, it is considered that the patient needs regular cleaning, so the patient needs to take a shower or other cleaning actions. When showering, the water sprayed from the shower head falls from the top of the patient's head and flows down the patient's neck. The fit between the protective plate and the gasket and the patient's neck is poor. When the patient raises his head, a gap is likely to appear between the gasket and the patient's neck, causing water to enter the patient's trachea and cause discomfort to the patient. The bacteria in the water are likely to cause infection at the tracheal incision site. If only the fitting site is treated, the patient will inevitably inhale more water vapor when showering, and there is still a risk of infection. For this reason, we propose a protective device for showering after tracheotomy patients. Summary of the invention

[0006] The purpose of the present invention is to provide a protective device for showering after tracheotomy surgery, so as to solve the problem raised in the above background technology that the water sprayed from the shower head falls from the top of the patient's head during showering, and the water flows down the patient's neck, and the fitting effect between the protective plate, the gasket and the patient's neck is poor. When the patient raises his head, a gap is likely to appear between the gasket and the patient's neck, causing water to enter the patient's trachea and cause discomfort to the patient, and it is easy for bacteria in the water to cause infection at the tracheotomy site. If only the fitting part is treated, the patient will inevitably inhale more water vapor when showering, and there is still a risk of infection.

[0007] To achieve the above object, the present invention provides the following technical solution: a protective device for showering a tracheotomy patient after surgery, comprising:

[0008] An outer bonding sheet for bonding to the surgical site, wherein the outer periphery of the outer bonding sheet is structured with an annular inclined surface that can guide water flow, an annular silicone ring is welded to the side of the outer bonding sheet that is bonded to the neck, and a water guide groove is structured on the outer periphery of the silicone ring, and the water guide groove extends to both ends of the silicone ring;

[0009] The side wall of the outer fitting sheet is structured with a circular hole, and a fixing sheet located on the inner side of the silicone ring is fixedly fitted on the side wall of the outer fitting sheet, a tracheal tube connected to the circular hole is inserted and fixed on the side wall of the fixing sheet, a threaded joint located on the outer side of the circular hole is integrally formed on the side of the outer fitting sheet away from the fixing sheet, and an air intake assembly is threadedly connected to the outer periphery of the threaded joint.

[0010] Preferably, the air inlet assembly comprises a threaded ring screwed and sealed on the outer periphery of the threaded joint, and an annular tube is integrally formed at one end of the threaded ring away from the outer bonding sheet, a filter tube is integrally formed at the inner periphery of the end of the annular tube, and an arc tube is integrally formed at the end of the filter tube, a threaded ring is integrally formed at the bottom end of the arc tube, and a threaded protrusion fixed to the top of the atomizer is screwed on the inner periphery of the threaded ring;

[0011] The top outer periphery of the filter tube is sealed with an arc-shaped sheet, and the inner periphery of the arc-shaped sheet is bonded with a filter screen located in the filter tube;

[0012] The outer periphery of the arc-shaped tube is sealed with a lap piece, and the inner periphery of the lap piece is bonded with a drying block extending into the arc-shaped tube.

[0013] Preferably, a toughness strip is integrally formed on the top of the outer fitting sheet, and a neck water retaining strip located above the outer fitting sheet when normally worn is bonded and fixed to the top of the toughness strip, and lower guide strips extending downward are bonded and fixed to both ends of the neck water retaining strip.

[0014] Preferably, symmetrically arranged waterproof elastic bands and plastic limiting strips are bonded and fixed to the side walls at both ends of the outer bonding sheet, and plastic inserts adapted to the plastic limiting strips are fixed to the ends of the waterproof elastic bands.

[0015] Preferably, the end of the plastic insert is configured to be wedge-shaped, and a plastic limiting strip is bonded and fixed to the side wall of the plastic insert.

[0016] Preferably, the end of the plastic inserting belt is configured with a socket, and the side wall of the plastic inserting belt is configured with a plurality of side openings which are distributed at equal intervals and communicated with the socket.

[0017] Preferably, the planes on which the two ends of the arc-shaped tube lie are perpendicular to each other.

[0018] Preferably, the filter screen is configured to be conical, and the thickness of the filter screen is smaller than the width of the arc-shaped sheet.

[0019] Among them, the outer fitting piece, plastic insert belt, plastic insert strip and neck water retaining strip are all made of TPU material, and the neck water retaining strip has strong elasticity. When worn, it can be opened to a certain extent and fit closely to the patient's neck near the lower jaw.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention provides an outer fitting sheet, a silicone ring, an annular inclined surface on the outer side of the outer fitting sheet, a water guide groove and a neck water retaining strip on the outer periphery of the silicone ring. When a tracheotomy patient takes a shower after the operation, the silicone ring can be filled between the outer fitting sheet and the patient's neck wound to play a sealing role. When the patient's head pitches up and down during the shower, the silicone ring can adaptively elastically deform to keep the wound site closed. When water falling along the patient's head contacts the outer fitting sheet and the silicone ring, the annular inclined surface and the water guide groove can quickly guide the water to drip from both sides of the wound. The neck water retaining strip and the lower guide strip can block the dripping water flow from above the wound, reduce the water flow at the outer fitting sheet and the silicone ring, and have a better waterproof effect. It can prevent water from entering the patient's trachea to cause discomfort to the patient and infection at the tracheotomy site due to bacteria in the water.

[0022] 2. The present invention provides an air intake assembly. When worn, the bottom of the arc tube faces downward, so the water vapor content inhaled during showering is less. In combination with the drying block inside the arc tube, the inhaled air needs to pass through the drying block. The drying block can dry the high-humidity air inhaled during showering to a large extent, effectively avoiding infection at the tracheotomy site due to inhaled water vapor.

[0023] 3. The air intake assembly of the present invention can be used to install the atomizer at the bottom of the arc tube through the cooperation of the threaded ring and the threaded protrusion, thereby providing a home airway humidification function with a wider range of functions. When performing airway humidification, it is convenient to remove the dry block from the arc tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example

[0034] See also Figure 1-Figure 7, a protective device for showering after tracheotomy in the figure comprises an outer fitting sheet 1 for fitting on the surgical site, the outer fitting sheet 1 has a certain flexibility, and when fitting on the patient's neck, it can be bent and deformed under the action of external force to fit closely to the neck, the outer periphery of the outer fitting sheet 1 is constructed with an annular inclined surface that can guide the water flow, an annular silicone ring 2 is welded on the side of the outer fitting sheet 1 that fits on the neck, and a water guide groove 3 is constructed on the outer periphery of the silicone ring 2, which extends to both ends of the silicone ring 2, and the silicone ring 2 has a certain thickness. When the neck pitches due to the patient's showering action, the silicone ring 2 adaptively expands and contracts under the action of its own elastic force, thereby keeping it closely fitted on the patient's neck, effectively preventing water from passing through the gap between the silicone ring 2 and the neck and entering the patient's trachea through the wound;

[0035] The side wall of the outer fitting sheet 1 is structured with a circular hole, and the side wall of the outer fitting sheet 1 is fitted and fixed with a fixing sheet 4 located on the inner side of the silicone ring 2, and the side wall of the fixing sheet 4 is plugged and fixed with a tracheal tube 5 connected to the circular hole. A threaded joint 9 located on the outside of the circular hole is integrally formed on the side of the outer fitting sheet 1 away from the fixing sheet 4, and an air intake assembly 10 is threadedly connected to the outer periphery of the threaded joint 9. The air intake assembly 10 can be flexibly disassembled and used according to the usage scenario, providing functions such as dry air during showering and airway humidification at home.

[0036] As a further improvement of the present technical solution, the air intake assembly 10 includes a threaded ring 11 screwed and sealed on the outer periphery of the threaded joint 9, and the threaded ring 11 is integrally formed with an annular tube 12 at one end away from the outer bonding sheet 1, and a filter tube 13 is integrally formed on the inner periphery of the end of the annular tube 12, and an arc tube 16 is integrally formed on the end of the filter tube 13, a threaded ring 17 is integrally formed on the bottom end of the arc tube 16, and a threaded protrusion 18 fixed to the top of the atomizer 19 is screwed on the inner periphery of the threaded ring 17, the top outer periphery of the filter tube 13 is sealed and bonded with an arc sheet 14, and the inner periphery of the arc sheet 14 is bonded with a filter screen 15 located in the filter tube 13, the outer periphery of the arc tube 16 is sealed and bonded with a lap sheet 20, and the inner periphery of the lap sheet 20 is bonded with a drying block 21 extending into the arc tube 16, and the planes at the two ends of the arc tube 16 are perpendicular.

[0037] When airway humidification is required at home, the nebulizer 19 is installed at the bottom of the arc tube 16 through the threaded ring 17 and the threaded protrusion 18. At this time, in order to ensure the humidity of the gas, the overlap sheet 20 is lifted up and the drying block 21 is removed. At this time, the water vapor generated in the nebulizer 19, which plays a therapeutic role, enters the endotracheal tube 5 through the arc tube 16, the filter tube 13, the annular tube 12 and the threaded ring 11. When wearing it in a shower, the nebulizer 19 needs to be removed and the drying block 21 is attached to the bottom surface of the overlap sheet 20. When the patient breathes, the inhaled air enters the arc tube 16 through the bottom of the arc tube 16, and passes through the drying block 21 when the high-humidity air flows, effectively reducing the water vapor content in the air, avoiding infection at the wound site due to inhaled water vapor, and at the same time, the filter screen 15 can also filter the normally inhaled air.

[0038] As a further improvement of the present technical solution, a tough strip 6 is integrally formed on the top of the outer fitting sheet 1, and a neck water retaining strip 7 is bonded and fixed to the top of the tough strip 6 and is located above the outer fitting sheet 1 when worn normally, and lower guide strips 8 extending downward are bonded and fixed to both ends of the neck water retaining strip 7.

[0039] When worn, the neck water retaining strip 7 fits against the patient's neck from above the wound site. When the water flows downward to above the neck water retaining strip 7, it can flow to the back of the neck water retaining strip 7 under the action of the slope setting of the neck water retaining strip 7, and flow down from the back of the patient's neck through the lower guide strip 8, thereby helping to improve the waterproof effect by changing the direction of the water flow.

[0040] As a further improvement of the present technical solution, the side walls at both ends of the outer bonding sheet 1 are bonded and fixed with symmetrically arranged waterproof elastic bands 22 and plastic limiting strips 24, the ends of the waterproof elastic bands 22 are fixed with plastic inserts 23 adapted to the plastic limiting strips 24, the ends of the plastic inserts 23 are wedge-shaped, and the side walls of the plastic inserts 23 are bonded and fixed with the plastic limiting strips 24, the ends of the plastic inserts 25 are configured with a socket 251, and the side walls of the plastic inserts 25 are configured with a plurality of side openings 252 that are evenly spaced and connected to the socket 251.

[0041] When wearing the device, the waterproof elastic band 22 and the plastic limiting strip 24 are passed around the patient's neck, and the end of the plastic insert 23 is inserted into the socket 251. After the plastic limiting strip 24 is inserted into the socket 251 and the plastic insert 23 is released, the plastic insert 23 has a reset tendency. At this time, the plastic limiting strip 24 can be flipped outward and embedded in the side opening 252 to prevent the plastic insert 23 from being separated from the plastic insert belt 25, thereby improving the stability during wearing and meeting the wearing requirements of patients with different diameters of necks. When it needs to be removed, the plastic limiting strip 24 can be pressed and then slowly pulled to separate the plastic insert 23 from the plastic insert belt 25.

[0042] As a further improvement of the present technical solution, the filter screen 15 is constructed in a conical shape, and the thickness of the filter screen 15 is smaller than the width of the arc-shaped sheet 14 .

[0043] The conical filter screen 15 has a larger end area, which not only ensures the air circulation speed, but also has a larger filtering area when filtering the air.

[0044] It should be noted that the present invention is a protective device for showering after tracheotomy. The patient wears the device with the help of medical staff, inserts the tracheal cannula 5 into the tracheal opening in advance, and then the medical staff respectively pinches the plastic insert 23 and the plastic insert belt 25 with both hands, wears the neck water retaining strip 7 on the patient's neck, keeps the outer fitting sheet 1 in contact with the neck, and then aligns the end of the plastic insert 23 with the socket 251 and inserts it until the plastic insert 23 can no longer be inserted, then releases the plastic insert 23, and the plastic insert 23 is inserted into the patient's neck. The strip 23 generates a reset tendency, and the plastic limiting strip 24 can be turned outward and embedded in the side opening 252 at the corresponding position, thereby the outer bonding sheet 1 and the silicone ring 2 are bonded to the outside of the patient's wound through the plastic insert strip 23 and the plastic insert belt 25, and the two ends of the outer bonding sheet 1 are adaptively deformed under the pulling action of the plastic insert strip 23 and the plastic insert belt 25 to keep close fit with the neck. When the patient needs to clean his body and take a shower, the neck water retaining strip 7 is bonded to the patient's neck from above the wound. When the water flows downward to When the patient is above the neck water retaining strip 7, the water can flow to the rear side of the neck water retaining strip 7 under the effect of the slope setting of the neck water retaining strip 7, and flow down from the back of the patient's neck under the guidance of the lower guide strip 8. When the patient breathes in the shower, the inhaled air enters the arc tube 16 through the bottom of the arc tube 16. When the high-humidity air flows, it passes through the drying block 21, and the water vapor is absorbed by the drying block 21 to effectively reduce the water vapor content in the air. When the neck pitches due to the patient's showering action, the silicone ring 2 adaptively expands and contracts under the effect of its own elastic force, thereby maintaining a close fit on the patient. The neck is effectively prevented from flowing through the gap between the silicone ring 2 and the neck and entering the patient's trachea through the wound, thereby fully ensuring that water enters the patient's tracheal wound during showering. In addition, when performing airway humidification at home, the atomizer 19 is installed at the bottom of the arc tube 16 through the threaded ring 17 and the threaded protrusion 18, and the lap piece 20 is lifted up in advance and the drying block 21 is removed. At this time, the water vapor generated in the atomizer 19, which has a therapeutic effect, enters the endotracheal tube 5 through the arc tube 16, the filter tube 13, the annular tube 12 and the threaded ring 11.
