Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a mask-type vomit collection device for an emergency department. Background Art

[0002] In the emergency department, some patients, such as those with food poisoning, will experience vomiting symptoms. At present, the emergency department usually prepares vomit trash cans for patients to receive the patients' vomit, but the vomit trash cans need to be open when in use, and the patients and nearby medical staff and other patients can see the vomit and smell the vomit, which causes discomfort to other people and even causes other people to vomit, increasing the workload of the emergency department. In addition, some patients need emergency surgery after entering the emergency department, but the patients do not follow the preoperative fasting and fasting, so vomiting is very likely to occur during the operation, which will not only contaminate the operating bed and the patient's own clothes, but also pose a risk of infection. Therefore, it is necessary to design a vomit collection device that can block sight, block odor, and is suitable for intraoperative vomiting. Summary of the invention

[0003] The present invention is intended to provide a mask-type vomit collection device for emergency departments, so as to solve the problem that the unpleasant smell caused by the patient's vomiting may easily cause discomfort to other personnel and cause contamination during surgery.

[0004] In order to achieve the above-mentioned purpose, the scheme of the present invention is: a mask-type vomit collection device for emergency department, comprising a mask body, a mouthpiece is provided on the inner side of the mask body, the mouthpiece comprises an arc-shaped flared portion and a circular tube portion, the arc-shaped flared portion is provided with an upper alveolar and a lower alveolar recessed inwardly, the circular tube portion is connected to the arc-shaped flared portion, and the circular tube portion has a hard tube section and a corrugated tube section; the end of the circular tube portion away from the arc-shaped flared portion is connected to a spitting pipe, the spitting pipe runs through the mask body, and the end of the spitting pipe away from the mouthpiece is connected to a conveying hose, and the end of the conveying hose away from the spitting pipe is connected to a collection box; an elastic ring is provided at the edge of the mask body, and two fixing belts are fixedly connected to the mask body, and the end of one fixing belt away from the mask body is detachably connected to the end of the other fixing belt away from the mask body.

[0005] The working principle and beneficial effects of this solution are as follows: In this solution, the curved flared part of the mouthpiece is for the patient to bite, and at the same time, the mask body is fixed to the patient's head through a fixing belt and covers the patient's mouth in the mask body. When vomiting, the vomit enters the spit tube through the mouthpiece, and then enters the collection box through the delivery hose, so that the vomit is transported to the collection box in a closed manner, and the vomit will not be exposed. The patient and other people will not see the vomit, nor will they smell the vomit, thereby avoiding other people from feeling uncomfortable and avoiding infection. Moreover, when the patient bites the mouthpiece, the patient's upper teeth sink into the upper alveolar groove of the curved flared part, and the patient's lower teeth sink into the lower alveolar groove of the curved flared part, so that the patient can bite the mouthpiece stably and the mouthpiece is not easy to fall out.

[0006] For patients during surgery, this solution can not only prevent patients from vomiting during surgery and contaminating the operating table and the patient's own clothes, avoiding the risk of infection from vomitus, but also prevent patients from biting their tongues during surgery.

[0007] In addition, the circular tube portion of the mouthpiece has a hard tube section and a corrugated tube section, so the overall length of the circular tube portion can be adjusted to suit the use of different patients.

[0008] Optionally, the elastic ring body is a rubber airbag, the rubber airbag is connected to an inflation hose, and one end of the inflation hose away from the rubber airbag is connected to the inflation balloon.

[0009] In this solution, the elastic ring is inflated and deflated through the inflatable balloon and the inflatable hose, so that the volume of the elastic ring changes, thereby changing the pressure exerted by the elastic ring on the patient's skin around the mouth. In this way, the patient holds the inflated balloon by himself, and when he feels that he is about to vomit, he squeezes the inflated balloon, the volume of the elastic ring expands, and the elastic ring fits the patient's skin around the mouth more closely, improving the sealing performance.

[0010] Optionally, a through tube is provided on the mask body, the spout tube is threadedly connected to the through tube, a radial hole I is opened on the circumference of the spout tube, a radial hole II is opened on the circumference of the through tube, and when the spout tube is screwed into the through tube, the radial hole I can be aligned with the radial hole II; the spout tube is detachably connected to the delivery hose.

[0011] In this solution, the spit tube is threadedly connected to the through tube. When the spit tube is screwed into the through tube and the radial hole I is aligned with the radial hole II, the interior of the spit tube is connected to the internal space of the mask body. In this way, if vomitus flows directly from the corners of the patient's mouth during vomiting, this part of the vomitus can enter the spit tube through the radial hole I and the radial hole II, and then enter the collection box through the delivery hose.

[0012] Optionally, the collecting box includes a box body and a box cover, the box cover is provided with a sampling assembly, the sampling assembly includes a sampling tube and a sampling barrel, the sampling tube vertically penetrates the box cover and is threadedly connected to the box cover, a rubber nipple is provided at the top of the sampling tube, the bottom end of the sampling tube is located in the sampling barrel, and the sampling barrel is connected to the inner wall of the box cover through a connecting rod; a connecting pipe for a conveying hose to pass through is vertically penetrated on the box cover, a sealing rubber ring is installed at the pipe mouth of the connecting pipe, and the inner diameter of the sealing rubber ring is smaller than the outer diameter of the conveying hose.

[0013] In this solution, considering that the vomitus of some patients, such as patients with food poisoning, needs to be sampled and analyzed, therefore, after the delivery hose passes through the connecting pipe, one end of the delivery hose located in the box is located in the sampling cylinder. In this way, the vomitus is first stored in the sampling cylinder, and after the sampling cylinder is full, the vomitus overflows to the bottom of the box; when the medical staff takes samples, they pinch the rubber nipple to expel the gas in the rubber nipple, and after releasing the rubber nipple, the vomitus in the sampling cylinder is sucked into the sampling tube under the action of negative pressure, and then the sampling tube is rotated to take out, and after the vomitus in the sampling tube is transferred to the sample dish, the sampling tube is threadedly connected to the box cover to complete the sampling. The sampling operation is simple, and the medical staff does not need to open the box cover, which greatly reduces the discomfort of the medical staff.

[0014] Optionally, a threaded through hole is provided on the box cover, and a threaded connection portion threadably matched with the threaded through hole is provided on the sampling tube, and an outer diameter of the threaded connection portion is larger than an outer diameter of the sampling tube.

[0015] In this solution, the outer diameter of the sampling tube is smaller than the outer diameter of the threaded connection portion. Thus, when taking and placing the sampling tube, the outer wall of the sampling tube is unlikely to touch the threaded through hole, thereby preventing vomitus on the outer wall of the sampling tube from adhering to the threaded through hole.

[0016] Optionally, the connecting tube is located above the sampling cylinder.

[0017] In this solution, when the connecting tube is located above the sampling cylinder, the delivery hose can move straight down into the sampling cylinder without bending, thereby ensuring that the sampling cylinder can smoothly store vomitus.

[0018] Optionally, an annular ear plate for supporting a box cover is provided on the top of the box body, a magnet is provided on the box cover, and the annular ear plate is an iron plate.

[0019] In this solution, the magnetic adsorption force between the magnet and the annular ear plate is used to tightly adsorb the cover plate on the top of the box body to ensure the sealing of the collection box.

[0020] Optionally, the top of the collection box is connected to an air storage bag.

[0021] In this solution, after the vomit enters the collection box, the internal pressure of the collection box increases, and the gas in the collection box spontaneously enters the air storage bag, thereby maintaining the internal pressure of the collection box and preventing the gas in the collection box from flowing back into the mask body.

[0029] Embodiment 1

[0030] This embodiment is basically Figure 1 and Figure 2As shown: A mask-type vomit collection device for emergency department, including a mask body 1, a mouthpiece 2 is provided on the inner side of the mask body 1, the mouthpiece 2 includes an arc-shaped flared portion 210 and a circular tube portion 220, the arc-shaped flared portion 210 is provided with an inwardly recessed upper alveolar 211 and a lower alveolar 212, the upper alveolar 211 is for the patient's upper teeth to sink into, and the lower alveolar 212 is for the patient's lower teeth to sink into; the circular tube portion 220 is connected to the arc-shaped flared portion 210, and the circular tube portion 220 has a hard tube section 221 and a corrugated tube section 222, the corrugated tube section 222 is retractable, so that the overall length of the circular tube portion 220 can be adjusted. One end of the circular tube portion 220 away from the arc-shaped flared portion 210 is connected to a spouting pipe 3, which penetrates the mask body 1. Specifically, a through-tube 4 is integrally formed on the mask body 1, and the spouting pipe 3 is threadedly connected to the through-tube 4; radial holes I 301 are opened on the circumference of the spouting pipe 3, and radial holes II 401 are opened on the circumference of the through-tube 4. When the spouting pipe 3 is screwed into the through-tube 4, the radial holes I 301 can be aligned with the radial holes II 401.

[0031] The end of the spit tube 3 away from the mouthpiece 2 is detachably connected to a delivery hose 5. In this embodiment, the detachable connection between the spit tube 3 and the delivery hose 5 is achieved by a threaded connection. The end of the delivery hose 5 away from the spit tube 3 is connected to a collection box 6. The collection box 6 includes a box body 610 and a box cover 620. The box cover 620 is provided with a sampling assembly. The sampling assembly includes a sampling tube 7 and a sampling barrel 8. The sampling tube 7 vertically penetrates the box cover 620 and is threadedly connected to the box cover 620. Specifically, in combination with Figure 3 As shown, a threaded through hole 621 is provided on the box cover 620, and a threaded connection part 710 threadably matched with the threaded through hole 621 is provided on the sampling tube 7, and the outer diameter of the threaded connection part 710 is larger than the outer diameter of the sampling tube 7. A rubber nipple 9 is provided at the top of the sampling tube 7, and the bottom end of the sampling tube 7 is located in the sampling barrel 8, and the sampling barrel 8 is connected to the inner wall of the box cover 620 through a connecting rod 10. A connecting pipe 11 for the delivery hose 5 to pass through is vertically penetrated on the box cover 620, and a sealing rubber ring 12 is fixedly installed in the connecting pipe 11. The top of the sealing rubber ring 12 has a flared opening to facilitate the insertion of the delivery hose 5, and the inner diameter of the sealing rubber ring 12 is smaller than the outer diameter of the delivery hose 5; in addition, the connecting pipe 11 is located above the sampling barrel 8.

[0032] The top of the box body 610 is welded with an annular ear plate 13 for supporting the box cover 620, and the box cover 620 is fixedly mounted with a magnet 14, and the annular ear plate 13 is an iron plate; thus, the box cover 620 is tightly adsorbed on the box body 610 by the magnetic adsorption force between the magnet 14 and the annular ear plate 13, thereby ensuring the sealing of the collection box 6. In addition, the box cover 620 is provided with an air storage bag 15, and the interior of the air storage bag 15 is connected to the interior of the box body 610.

[0033] The edge of the mask body 1 is welded with an elastic ring 16, combined with Figure 4As shown, two fixing straps 17 are fixedly connected to the mask body 1, and the end of one fixing strap 17 away from the mask body 1 is detachably connected to the end of the other fixing strap 17 away from the mask body 1. Specifically, the end of one fixing strap 17 away from the mask body 1 is fixedly connected with a Velcro hook surface 18, and the end of the other fixing strap 17 away from the mask body 1 is fixedly connected with a Velcro velvet surface 19.

[0034] When in use, the garbage bag 20 is placed inside the box 610, and the opening of the garbage bag 20 is turned outward at the top of the box 610. In this way, the vomitus entering the collection box 6 will be placed inside the garbage bag 20, thereby preventing the vomitus from directly contacting the inner wall of the box 610, thereby avoiding the need to clean the box 610. Subsequently, the end of the delivery hose 5 away from the spit tube 3 is pulled into the sampling tube 8, and then the box cover 620 is placed on the box 610, and the box cover 620 is tightly fastened to the box 610 by the magnetic attraction between the magnet 14 and the annular ear plate 13. In this way, the preparation of the collection box 6 is completed for the patient to use.

[0035] When in use, the medical staff inserts the arc-shaped flared portion 210 into the patient's oral cavity and lets the patient bite the arc-shaped flared portion 210. Specifically, the patient's upper teeth are inserted into the upper alveolar 211, and the patient's lower teeth are inserted into the lower alveolar 212, thereby tightening the arc-shaped flared portion 210 to prevent the mouthpiece 2 from falling out. Next, the medical staff presses the mask body 1 so that the elastic ring body 16 on the mask body 1 contacts the patient's skin around the mouth, thereby covering the patient's mouth in the mask body 1. Then, the medical staff adheres the two fixing straps 17 through the Velcro hook surface 18 and the Velcro velvet surface 19, thereby wearing the mask body 1 on the patient's head. In the above process, since the circular tube portion 220 of the mouthpiece 2 has a bellows section 222, and the bellows section 222 is retractable, the overall length of the circular tube portion 220 is adjustable, and can adapt to the movement of the mask body 1 after the patient bites the arc-shaped flared portion 210.

[0036] When the patient vomits, the vomit enters the spit tube 3 through the arc-shaped expansion part 210 and the circular tube part 220, and then the spit tube 3 enters the delivery hose 5, and then enters the sampling tube 8 through the delivery hose 5. After the vomit in the sampling tube 8 is filled, the vomit overflows into the garbage bag 20 of the box body 610, thereby the vomit is sealed and transported to the collection box 6. The vomit will not be exposed, and the patient and other personnel will not see the vomit, nor will they smell the vomit, thereby avoiding discomfort to other personnel. Moreover, after the patient wears the mask body 1 for surgery, if the patient vomits during the operation, the vomit can be sealed and transported to the collection box 6, which will not contaminate the operating bed, clothes, etc., and also avoid vomit infection; and the arc-shaped expansion part 210 separates the patient's upper teeth and lower teeth, thereby preventing the patient from biting his tongue. In addition, while the vomitus enters the garbage bag 20 of the box body 610, the gas in the collection box 6 enters the air storage bag 15, thereby balancing the air pressure in the collection box 6 and preventing the gas in the collection box 6 from flowing back into the mask body 1.

[0037] In addition, if the patient vomits during surgery or when the patient is unconscious, vomitus may flow out directly from the corners of the patient's mouth. At this time, the mask body 1 can concentrate the vomitus in the internal space of the mask body 1 to prevent the vomitus from leaking out, and the vomitus in the mask body 1 enters the spit tube 3 through the radial holes I 301 and the radial holes II 401 (note that before wearing the mask body 1, rotate the spit tube 3 so that the radial holes I 301 and the radial holes II 401 are aligned), and then enters the collection box 6 through the delivery hose 5.

[0038] When sampling is needed, the medical staff pinches the rubber nipple 9, removes the gas in the rubber nipple 9, and then releases the rubber nipple 9, and the vomit in the sampling cylinder 8 is sucked into the sampling tube 7 under the action of negative pressure; then, the medical staff rotates the sampling tube 7 counterclockwise, and after the threaded connection part 710 is separated from the threaded through hole 621 on the box cover 620, the sampling tube 7 can be taken out; then, the vomit in the sampling tube 7 is transferred to the sample dish, and the sampling tube 7 is inserted back into the threaded through hole 621, and then the sampling tube 7 is rotated clockwise to reset the sampling tube 7 and complete the sampling. In this way, when the medical staff takes samples, there is no need to open the box cover 620, the smell of vomit will not be dispersed in large quantities, and the sampling operation will not affect the collection process of vomit.

[0039] After vomiting is over, the mask body 1 is removed, and the delivery hose 5 is pulled out from the connecting tube 11, and the mask body 1, the mouthpiece 2 and the delivery hose 5 are thrown into the medical waste bin. Then the box cover 620 is removed, and the garbage bag 20 is closed and thrown into the garbage bin; the box cover 620, the sampling cylinder 8 and the sampling tube 7 are cleaned, disinfected, and reset for the next use. In addition, since the vomiting tube 3 and the through tube 4 are detachable, the mask body 1 can be retained and reused after cleaning and disinfection, reducing the waste of materials.

[0040] Embodiment 2

[0041] The difference between this embodiment and the first embodiment is that: Figure 5 As shown, in this embodiment, the elastic ring body 16 is a rubber airbag, the rubber airbag is connected to an inflation hose 21, and one end of the inflation hose 21 away from the rubber airbag is connected to an inflation balloon 22.

[0042] In the present embodiment, when the patient has self-consciousness, the inflatable balloon 22 is held in the hand, and when the patient senses that he is about to vomit, the inflatable balloon 22 is squeezed, so that the gas in the inflatable balloon 22 enters the rubber balloon (elastic ring body 16) through the inflatable hose 21, and the volume of the rubber balloon (elastic ring body 16) increases, thereby increasing the pressure on the patient's skin around the mouth, improving the fit, and ensuring the sealing of the mask body 1. In normal times, the volume of the rubber balloon (elastic ring body 16) is small, and the pressure on the patient's skin around the mouth is small, thereby avoiding the elastic ring 16 from tightly compressing the patient's skin around the mouth for a long time, and improving the comfort. In addition, in the operation, after the inflatable balloon 22 is squeezed and the rubber balloon (elastic ring body 16) expands, the inflatable hose 21 is clamped by a stopper clamp, and it can be ensured that the rubber balloon (elastic ring body 16) remains in an expanded state, thereby ensuring the sealing of the mask body 1, and avoiding vomitus from leaking.
