Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an upper gastrointestinal bleeding nursing device. Background Technique

[0002] Upper gastrointestinal bleeding refers to bleeding in the digestive tract above the ligament of Treitz, including the esophagus, stomach, duodenum, or pancreaticobiliary tract and other lesions. Upper gastrointestinal bleeding is a serious complication of upper gastrointestinal diseases, especially massive upper gastrointestinal bleeding, which is mainly manifested as hematemesis, melena, and varying degrees of peripheral circulatory failure. If not properly treated, it can endanger life.

[0003] The condition of patients with upper gastrointestinal bleeding often recurs. Repeated hematemesis in patients is a sign of rebleeding. Therefore, during the bleeding period, patients must stay in bed, lie flat, and turn their heads to one side to prevent asphyxia caused by hematemesis. However, when the patient is sleeping or fainting, it is inevitable that the head may turn, resulting in a situation of lying on the back. If hematemesis occurs at this time, the blood cannot be discharged from the oral cavity in time, and it is easy to flow back into the respiratory tract, causing the patient to cough violently. In severe cases, it may cause asphyxia due to airway obstruction, endangering the patient's life safety. For this reason, we propose an upper gastrointestinal bleeding nursing device. Content of the Utility Model

[0004] One technical problem to be solved by this application is: when a patient with upper gastrointestinal bleeding is sleeping or fainting, it is inevitable that the head may turn, resulting in a situation of lying on the back. If hematemesis occurs at this time, the blood cannot be discharged from the oral cavity in time, and it is easy to flow back into the respiratory tract, causing the patient to cough violently. In severe cases, it may cause asphyxia due to airway obstruction, endangering the patient's life safety.

[0005] To solve the above technical problem, the embodiment of this application provides an upper gastrointestinal bleeding nursing device, which includes a helmet worn on the patient's head, and further includes:

[0006] An airbag, the airbag is embedded in the helmet, the periphery of the airbag is fixedly connected to the inner wall of the helmet, and an inflation structure for inflating the airbag is installed on the helmet;

[0007] A transmission device, one end of the transmission device is fixedly connected to the top of the helmet, the other end of the transmission device is fixedly installed with a gear, a rectangular frame is sleeved on the outer surface of the gear, and a toothed groove plate is slidably connected to the upper and lower inner walls of the rectangular frame, and one adjacent side of the two toothed groove plates is meshed with the gear through a toothed groove;

[0008] An elastic reset device, the elastic reset device is arranged in the rectangular frame, one end of the elastic reset device is fixedly connected to the end of the toothed groove plate, and the other end of the elastic reset device is fixedly connected to the inner wall of the rectangular frame.

[0009] Preferably, the inflation structure comprises an inflation tube running through the headgear, one end of the inflation tube extends into the airbag, and a valve fixed to the headgear is mounted on the other end of the inflation tube.

[0010] Preferably, the transmission device includes two transmission shafts, and the adjacent ends of the two transmission shafts are fixedly connected with a joint and a rotating plate, the rotating plate is embedded in the joint, and a pin is installed at the connection between the rotating plate and the joint, and the ends of the two transmission shafts away from each other are fixed to the helmet and the gear respectively.

[0011] Preferably, guide grooves are provided on the upper and lower inner walls of the rectangular frame, and a slider is fixedly connected to the side of the tooth plate that is in contact with the inner wall of the rectangular frame. The slider is embedded in the guide groove and is slidably connected to the rectangular frame through the guide groove.

[0012] Preferably, the elastic reset device is a spring, and the maximum compression length of the spring is not less than half of the circumference of the gear.

[0013] Preferably, a mounting plate is fixedly connected to a side of the rectangular frame away from the headgear, and a plurality of fixing holes are formed on the mounting plate.

[0014] Preferably, a slide is fixedly connected to the inner wall of the rectangular frame, a slide rod is passed through the end of the slide away from the inner wall of the rectangular frame, the end of the slide rod located in the inner cavity of the slide is fixedly connected to the piston, the end of the slide located outside the slide is fixed to the toothed plate, and the spring is wound around the slide and the slide rod.

[0015] The utility model has at least the following beneficial effects:

[0016] 1. When the user turns their head, the helmet rotates. The gear fixed at the end of the drive shaft drives the toothed plate to slide within the rectangular frame. The toothed plate can pull the spring to deform during the sliding process. When the patient's neck muscles relax, the spring pulls the two toothed plates in the opposite direction under its own restoring force to reset the head, correcting the patient's head to a position tilted to the side of the bed. This can avoid the patient lying on his back when vomiting blood, which can cause suffocation due to the inability to drain the blood in time.

[0017] 2. When the patient turns his head, the traction spring deforms and simultaneously drives the slide rod to pull the piston to slide in the slide cylinder. When the patient's neck muscles relax, the spring drives the alveolar plate to reset and at the same time drives the piston to reset. The friction resistance between the piston and the inner wall of the slide cylinder forms a damping effect, reducing the spring reset speed and trying to avoid the problem of the spring resetting too fast, which may sprain the patient's neck.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1

[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0028] An upper gastrointestinal bleeding nursing device includes a helmet 1 worn on the patient's head, and further includes:

[0029] An airbag 2 embedded in the helmet 1, the peripheral side of the airbag 2 is fixedly connected to the inner wall of the helmet 1, and an inflation structure for inflating the airbag 2 is installed on the helmet 1. By inflating the airbag 2 through the inflation structure, the airbag 2 expands to fit the patient's head;

[0030] A transmission device is fixed to the top of the helmet 1 at one end, and a gear 9 is fixedly installed at the other end of the transmission device. A rectangular frame 10 is provided on the outer surface of the gear 9. A toothed plate 11 is slidably connected to the inner walls of the upper and lower sides of the rectangular frame 10. The adjacent sides of the two toothed plates 11 are meshed with the gear 9 through the tooth groove. When the gear 9 rotates, it can drive the toothed plates 11 to slide inside the rectangular frame 10;

[0031] An elastic reset device is provided in the rectangular frame 10, one end of the elastic reset device is fixed to the end of the tooth plate 11, and the other end of the elastic reset device is fixed to the inner wall of the rectangular frame 10. When the tooth plate 11 slides, the elastic reset device can be pulled to produce elastic deformation, and the elastic reset device can be used to restore itself to pull the tooth plate 11 back to its original position; and further comprising:

[0032] The inflation structure includes an inflation tube 3 that passes through the headgear 1. One end of the inflation tube 3 extends into the airbag 2. The other end of the inflation tube 3 is provided with a valve 4 that is fixed to the headgear 1.

[0033] The transmission device includes two transmission shafts 5, the adjacent ends of the two transmission shafts 5 are fixedly connected to a joint 6 and a rotating plate 7, the rotating plate 7 is embedded in the joint 6, and a pin 8 is installed at the connection between the rotating plate 7 and the joint 6. The ends of the two transmission shafts 5 that are away from each other are fixed to the helmet 1 and the gear 9 respectively; it also includes:

[0034] Guide slots are provided on the inner walls of the upper and lower sides of the rectangular frame 10. A slider is fixedly connected to the side where the toothed plate 11 is in contact with the inner wall of the rectangular frame 10. The slider is embedded in the guide slot and is slidably connected to the rectangular frame 10 through the guide slot.

[0035] The elastic reset device is a spring 12 , and the maximum compression length of the spring 12 is not less than half of the circumference of the gear 9 .

[0036] When the headrest is in use, the patient lies flat on the bed and uses the straps to fix the patient's body. The helmet 1 is then worn on the patient's head. The air in the airbag 2 is inflated through the inflation tube 3, so that the airbag 2 expands to fit the patient's head. At this time, the helmet 1 can be installed on the bed through the mounting plate 13 and the fixing hole 14. When the patient faints or turns his head unconsciously during sleep, the helmet 1 will be driven to rotate. The rotation of the helmet 1 drives the gear 9 to rotate synchronously through the transmission shaft 5. Under the action of the gear teeth of the gear 9, the two tooth plates 11 are driven to slide in the opposite direction. The tooth plates 11 will pull the spring 12 to deform during the sliding process. When the muscles at the patient's neck relax, the spring 12 pulls the two tooth plates 11 in the opposite direction under the action of its own restoring force to move, and drives the helmet 1 to reverse through the gear 9 and the transmission shaft 5, correcting the patient's head to a posture leaning to one side of the bed, so as to avoid the patient from vomiting blood and not being able to discharge the blood in time, which is easy to flow back into the respiratory tract and cause the patient to choke and cough violently. In severe cases, it may suffocate due to airway obstruction, endangering the patient's life safety.

[0037] Example 2

[0038] See also Figures 5-6 , the utility model provides a technical solution:

[0039] Different from Example 1, this solution provides another embodiment of the upper gastrointestinal bleeding nursing device in gastroenterology:

[0040] A nursing device for upper gastrointestinal bleeding, comprising a helmet 1 worn on a patient's head, and further comprising:

[0041] The airbag 2 is embedded in the headgear 1, and its circumferential side is fixedly connected to the inner wall of the headgear 1. The headgear 1 is equipped with an inflation structure for inflating the airbag 2. The inflation structure inflates the airbag 2, thereby expanding the airbag 2 to fit the patient's head.

[0042] A transmission device is fixed to the top of the helmet 1 at one end, and a gear 9 is fixedly installed at the other end of the transmission device. A rectangular frame 10 is provided on the outer surface of the gear 9. A toothed plate 11 is slidably connected to the inner walls of the upper and lower sides of the rectangular frame 10. The adjacent sides of the two toothed plates 11 are meshed with the gear 9 through the tooth groove. When the gear 9 rotates, it can drive the toothed plates 11 to slide inside the rectangular frame 10;

[0043] An elastic reset device is provided in the rectangular frame 10, one end of the elastic reset device is fixed to the end of the tooth plate 11, and the other end of the elastic reset device is fixed to the inner wall of the rectangular frame 10. When the tooth plate 11 slides, the elastic reset device can be pulled to produce elastic deformation, and the elastic reset device can be used to restore itself to pull the tooth plate 11 back to its original position; and further comprising:

[0044] A slide 15 is fixedly connected to the inner wall of the rectangular frame 10, and a slide rod 16 is passed through the end of the slide 15 away from the inner wall of the rectangular frame 10. The end of the slide rod 16 located in the inner cavity of the slide 15 is fixedly connected to the piston 17, and the end of the slide 15 located outside the slide 15 is fixed to the toothed plate 11, and the spring 12 is wound around the slide 15 and the slide rod 16.

[0045] When the patient turns his head, the traction spring 12 is deformed and the slide rod 16 is synchronously driven to pull the piston 17 to slide in the slide cylinder 15. Since the piston 17 is in close contact with the inner wall of the slide cylinder 15, the piston 17 will generate friction resistance during the sliding process. The friction resistance is less than the restoring force of the spring 12. Therefore, when the patient's neck muscles relax, the spring 12 drives the alveolar plate 11 to reset and at the same time drives the piston 17 to reset. The friction resistance between the piston 17 and the inner wall of the slide cylinder 15 forms a damping effect, which reduces the reset speed of the spring 12 and avoids the problem of spraining the patient's neck when the spring 12 is quickly reset.
