Description

Technical Field

[0001] The invention relates to the technical field of nursing equipment, and in particular to a gastroenterology bleeding nursing device. Background Art

[0002] Gastrointestinal bleeding is a common clinical symptom. Gastrointestinal bleeding refers to gastrointestinal bleeding that occurs above the Treitz ligament, mainly including the esophagus, stomach, duodenum, pancreas and gallbladder. As a serious complication of upper gastrointestinal diseases, gastrointestinal bleeding poses a great health threat to patients. Its main clinical manifestations include vomiting blood, bloody stools, and varying degrees of peripheral circulatory failure. If not handled properly, it may endanger the patient's life. During the treatment process, good nursing work can not only help promote the recovery of the disease, but also effectively prolong the bleeding cycle, reduce the number of bleeding times, and provide patients with more comprehensive treatment guarantees.

[0003] After searching, the Chinese patent with publication number CN112220621B discloses a nursing device for upper gastrointestinal bleeding in the Department of Gastroenterology. It includes: a nursing bed, a protective seat, a connecting rod, a motor, a connecting part, a clamping part, a microprocessor, a power supply and a switch. The protective seat is connected to the head of the nursing bed, the connecting rod is vertically connected to the protective seat, the motor is arranged in the protective seat, the output shaft is connected to the connecting rod, the connecting part is vertically fixed to the front end of the connecting rod, the two clamping parts are vertically connected to the connecting part and are parallel to each other, the microprocessor is arranged in the protective seat, the microprocessor and the motor are connected through the motor controller signal, the power supply is respectively connected to the motor and the microprocessor, the switch is arranged on the protective seat, and is electrically connected to the power supply, and the switch is used to turn on or off the power supply. The nursing device for upper gastrointestinal bleeding in the Department of Gastroenterology provided by the present invention ensures that the patient will not vomit blood and suffocate due to lying on his back while sleeping. However, this solution still has the following shortcomings in actual use:

[0004] During sleep, patients with gastrointestinal bleeding may experience head displacement due to unconscious body movement. When the patient's head moves and deviates from the preset safe position of the nursing device, the existing head control device may not be able to respond and adjust in time, thereby failing to ensure that the patient's head is maintained at an appropriate tilt angle, resulting in the patient being unable to effectively avoid the risk of vomiting blood and suffocation. In addition, patients with gastrointestinal bleeding may suddenly have the urge to vomit blood at night. If the patient's head is still fixed in an external force clamping device at this time, they cannot quickly adjust the position of their head to accommodate the need for vomiting blood. Patients may vomit blood directly on the bed due to the inability to move their heads in time, which not only causes contamination of bedding, but also may increase the risk of infection for patients, while placing an additional burden on subsequent cleaning and care work.

[0005] Therefore, the present application provides a gastroenterology bleeding care device to meet the needs of controlling the patient's head and the patient's vomiting. Summary of the invention

[0065] Beneficial effects of the present invention:

[0066] 1. This gastroenterology bleeding care device, by setting up a movable frame and an adjustment component, allows patients to easily adjust the position of the clamping component according to their own needs, ensuring that the head is stably supported when lying on the side, effectively preventing the risk of suffocation caused by vomiting blood, and improving the safety and comfort of patients.

[0084] like Figures 1 to 9As shown, a nursing device for gastroenterology bleeding comprises a nursing bed; a U-shaped frame 1, fixedly mounted at the head position of the nursing bed, and with its opening direction vertically downward; a movable frame 2, slidably mounted vertically in the middle of the U-shaped frame 1 and passing through the U-shaped frame 1; a limiting card slot 21, which is provided on the side wall of the movable frame 2 along the length direction of the U-shaped frame 1, and is a right-angled triangular card slot in a linear array; two fixed plates 22, symmetrically fixedly mounted on the movable frame 2 passing through the U-shaped frame 1 and close to one end side wall of the nursing bed; two tension springs 23, symmetrically fixedly mounted between the fixed plate 22 and the U-shaped frame 1; a slide slot 14, which is provided inside the top end of the U-shaped frame 1 and connected to the limiting card slot 21 corresponding to the position; a slide bar 15 is slidably mounted in the slide slot 14, and one end of the slide bar 15 close to the movable frame 2 is fixedly mounted with a right-angled triangle tooth adapted to the limit slot 21; a compression spring 16 is fixedly mounted in the slide slot 14, and the two ends of the slide bar 15 are fixedly connected to the inner wall of the slide slot 14; a clearance groove 17 is provided on the top and bottom walls of the U-shaped frame 1 and is connected to the slide slot 14; an operating rod 18 is fixedly mounted at the bottom of the slide bar 15 and passes through the clearance groove 17; an adjustment component is arranged at the top of the U-shaped frame 1 at a position corresponding to the movable frame 2; a clamping component is arranged at the bottom of the movable frame 2; a vomiting component is arranged on the side wall of the U-shaped frame 1;

[0085] When in use, the patient lies on the nursing bed before sleeping and puts his head on the side. The patient can operate the adjustment component to make the movable frame 2 slide downward along the U-shaped frame 1. The movable frame 2 slides downward so that the inclined surface of the inverted triangular groove in the limiting groove 21 squeezes the regular triangular tooth at one end of the slide bar 15, and the slide bar 15 slides inward along the slide groove 14. When the patient has adjusted the height of the movable frame 2, the slide bar 15 slides outward along the slide groove 14 under the action of the compression spring 16 and re-engages with the limiting groove 21. The tension spring 23 generates an upward pulling force on the movable frame 2, and the limit groove 21 is engaged. The plane of the inverted triangle slot squeezes the plane of the equilateral triangle tooth at one end of the slide bar 15, and the movable frame 2 can be limited and fixed at this time. After adjusting the height, the clamping assembly can clamp the patient's forehead to keep the patient's head on the side, and vomiting blood and suffocation will not occur. When the patient has the urge to vomit blood at night, he only needs to push the operating rod 18 to drive the slide bar 15 to slide and release the movable frame 2. The movable frame 2 automatically moves upward under the action of the tension spring 23 to release the patient's head. The patient can quickly and freely turn sideways to vomit blood, avoiding contamination and infection in the bed caused by vomiting blood due to clamping the head.

[0086] like Figure 1 , Figure 2 , Figure 5As shown, the adjustment assembly includes: a mounting block 11, fixedly mounted on the top surface of the U-shaped frame 1; an adjusting wheel 111, rotatably mounted on the side wall of the mounting block 11 along the width direction of the U-shaped frame 1, and the adjusting wheel 111 is provided with a circular array of teeth that mesh with the limit slot 21; a transmission wheel 112, fixedly mounted on the end of the adjusting wheel 111 away from the mounting block 11; a support frame 12, fixedly mounted on the U-shaped frame 1 near the transmission wheel 112 at the vertex of the support frame 12; a pulley assembly 121, rotatably mounted on the support frame 12; a synchronous belt 122, sleeved on the transmission wheel 112 and the pulley assembly 121; a mounting block 13, fixedly mounted on the bottom of the side wall of the U-shaped frame 1 close to the support frame 12; a driving wheel 131, rotatably mounted on the mounting block 13; a synchronous belt 133, sleeved on the pulley assembly 121 and the driving wheel 131; a hand wheel 132, fixedly mounted on the driving wheel 131;

[0087] The patient can manually turn the handwheel 132 so that the driving wheel 131 rotates and drives the pulley assembly 121 to rotate. The pulley assembly 121 transmits the rotation to the transmission wheel 112, and then drives the adjusting wheel 111 to rotate. The teeth on the adjusting wheel 111 can mesh with the slots in the limit slots 21, and the movable frame 2 is pushed downward when the adjusting wheel 111 rotates. The pulley assembly 121 plays a transmission connection role. By arranging the pulley assembly 121 at a corner of the U-shaped frame 1 for transmission, the handwheel 132 can be set at the position closest to the patient, which is convenient for the patient or nursing staff to manually operate. The pulley assembly 121 can be composed of two fixedly connected pulleys, one connected to the driving wheel 131, and the other connected to the transmission wheel 112. By making the pulley diameter connected to the driving wheel 131 larger than the pulley diameter connected to the transmission wheel 112, it can save effort, which can meet the needs of weak patients to easily adjust the movable frame 2.

[0088] like Figure 1 , Figure 2 , Figure 3 As shown, the clamping assembly includes: a baffle 3, fixedly mounted on the bottom surface of one end of the movable frame 2 passing through the U-shaped frame 1 close to the nursing bed; two guide grooves 31, symmetrically opened on the baffle 3; two mounting blocks 32, symmetrically mounted on the top surfaces of both ends of the baffle 3 in the length direction; a threaded rod 33, rotatably mounted between the two mounting blocks 32 and passing through the movable frame 2, and the thread directions of the two ends of the threaded rod 33 are opposite; two clamping plates 34, symmetrically sleeved on both ends of the threaded rod 33, passing through the guide groove 31 and slidably connected to the guide groove 31; a hand wheel 2 35, fixedly mounted on one end of the threaded rod 33 passing through the mounting block 32; arc blocks 36 are fixedly mounted on the opposite side walls of the two clamping plates 34 respectively;

[0089] By adjusting the position of the movable frame 2, the baffle 3 can be made to slightly contact the patient's forehead, thereby fixing the movable frame 2 in a suitable position, and then the threaded rod 33 can be driven to rotate by turning the hand wheel 2 35. The threads at both ends of the threaded rod 33 are in opposite directions. Therefore, when rotating, the splints 34 on both sides can be made to slide synchronously and symmetrically along the guide groove 31 relative to each other, and the spacing between the splints 34 can be changed to fully stabilize the patient's forehead and prevent the patient from unconsciously laying his head flat. The arc block 36 can adapt to the curve shape of the head, can effectively fit the patient's forehead, and better play a fixing role.

[0090] like Figure 1 , Figure 4 , Figure 7 As shown, the hematemesis component includes: a mounting plate 4, fixedly mounted on the bottom surface of the U-shaped frame 1 near the end of the mounting block 13; a clamping plate 41, fixedly mounted on the side wall of the U-shaped frame 1 near the mounting plate 4, and a circular arc hole is opened in the middle of the clamping plate 41; a waste box 44, fixedly mounted on the mounting plate 4; a drainage tube 43, which is installed through the top surface of the waste box 44, and the middle part of the drainage tube 43 is fixedly arranged on the mounting plate 4 at an angle and one end away from the waste box 44 is higher than the other end; a splash guard 42, fixedly mounted on the end of the drainage tube 43 away from the waste box 44, and the The top diameter of the splash shield 42 is larger than the diameter of the arc-shaped hole opened on the card plate 41; a blood sample separation assembly is arranged between the mounting plate 4 and the drainage tube 43; the blood sample separation assembly comprises: a sampling box 5, fixedly mounted on the mounting plate 4 at a position below the inclined drainage tube 43; a drainage cover 51, fixedly mounted on the bottom wall of the inclined portion of the drainage tube 43, and arranged in an inverted cone shape, the bottom of the drainage cover 51 passes through the sampling box 5 and extends into the interior of the sampling box 5; a plurality of filter holes 431, evenly arranged on the bottom wall of the inclined portion of the drainage tube 43 at a position inside the drainage cover 51;

[0091] When the patient needs to vomit blood, he can pick up the splash shield 42 placed on the pallet 41 and put it on his mouth, and the vomit will flow down the drainage tube 43. The drainage tube 43 is placed at an angle so that the vomit can flow into the waste box 44 in a concentrated manner, which is convenient for the treatment of the vomit in the waste box 44. Clinically, it is often necessary to detect the color, properties and amount of the blood sample of vomiting blood. By setting up a blood sample separation component, when the vomit flows through the inclined part of the drainage tube 43, some pollutants are filtered through the filter hole 431, and the blood sample after preliminary filtration will flow into the sampling box 5 along the drainage shield 51, which is convenient for nursing staff or doctors to directly obtain a cleaner blood sample.

[0092] like Figure 8 , Fig. 9As shown, a sample dividing assembly is provided in the sampling box 5; the sample dividing assembly includes: a driving motor 52, fixedly mounted on the top surface of the sampling box 5, the output end of the driving motor 52 passes through the sampling box 5 and extends into the interior of the sampling box 5; a slide rail 6, fixedly mounted on the bottom wall of the sampling box 5, and provided with a cross-shaped sliding groove; a transmission chain 61, slidably mounted in the slide rail 6, and tooth holes are evenly arranged on the transmission chain 61; a through hole 66, which is arranged at a position corresponding to the output end of the slide rail 6 and the driving motor 52; a gear 53, fixedly mounted on the output end of the driving motor 52 located inside the sampling box 5, and passing through the through hole 66 Meshed with the transmission chain 61; a plurality of guide blocks 62 are evenly fixedly mounted on the top surface of the transmission chain 61 and slidably connected with the slide rail 6; a plurality of sampling tube holders 63 are fixedly mounted on the guide blocks 62; a plurality of sampling tube barrels 64 are slidably mounted in the sampling tube holders 63; a plurality of sampling tube covers 65 are hinged on the top of the sampling tube barrels 64; a button 54 is arranged at one end of the drainage tube 43 close to the splash shield 42; a trapezoidal block 67 is fixedly mounted on the inner side wall of the sampling box 5 at a position corresponding to the sampling tube cover 65, and the bottom surface of the trapezoidal block 67 is arranged coplanar with the top surface of the sampling tube cover 65 when it is closed;

[0093] Every time the patient vomits at night or during the day, the initially filtered blood sample can flow into the sampling tube 64 placed directly below the drainage hood 51 extending into the sampling box 5. After the vomiting of blood is over, the patient presses the button 54 set at the handheld end of the drainage tube 43 to start the drive motor 52 to rotate. The output end of the drive motor 52 drives the gear 53 to rotate. The teeth of the gear 53 mesh with the transmission chain 61 and drive the transmission chain 61 to slide along the slide rail 6, driving the guide block 62 fixedly installed on the transmission chain 61 to move, and driving the sampling tube holder 63 fixedly installed on the guide block 62 to slide, so that the sampling tube 64 with blood sample collected in the sampling tube holder 63 is moved away from the lower end of the drainage hood 51, and the empty sampling tube 64 is moved to the drainage hood 5 1, the diameter of the sampling tube 64 is larger than the opening at the lower end of the drainage cover 51, so as to ensure that the blood sample flows into the sampling tube 64. When the sampling tube 64 is placed on the sampling tube holder 63, it is in an open shape. The sampling tube cover 65 is opened more than 90 degrees to ensure smooth collection of the blood sample. When the hematemesis sample is collected and moved, the sampling tube cover 65 contacts the inclined surface of the inverted trapezoidal block 67 during movement and is gradually pressed and covered on the sampling tube 64. The bottom surface of the trapezoidal block 67 is set at the height when the sampling tube cover 65 is closed, which can ensure that the collected sampling tubes are kept sealed to avoid sample contamination. According to the number and order of the closed sampling tubes, the number of hematemesis of the patient and the blood sample corresponding to each hematemesis can be known, which is convenient for nursing and monitoring the patient's physical condition.
