Description

Technical Field

[0001] The present invention relates to the field of gastric lavage beds, and more particularly to a multifunctional gastric lavage bed. Background Art

[0002] Gastric lavage is a common first aid and treatment method, mainly used to remove poisons, foreign bodies or excessive food in the stomach, so as to reduce the absorption of poisons, relieve gastric discomfort or prepare for subsequent treatment. During gastric lavage, the patient usually needs to lie on the left side with the head lower than the feet to prevent the lavage fluid from being aspirated into the trachea and prevent vomitus from blocking the trachea. However, traditional gastric lavage beds often lack effective body position adjustment functions, which can easily affect the smooth progress of gastric lavage. Moreover, during gastric lavage, patients often show restlessness due to discomfort. Most traditional gastric lavage beds are not equipped with special restraint devices, and medical staff can only fix the patient manually or use simple straps to restrain the patient. This method not only has limited effect, but may also cause compressive injuries to the patient due to too tight straps.

[0003] In addition, during gastric lavage, the lavage fluid and vomitus are prone to splash, which will not only contaminate the surrounding environment, but also increase the risk of infection for medical staff. Traditional gastric lavage beds usually do not have anti-splash measures, and medical staff need to wear additional protective equipment during operation, increasing the complexity of operation and the work burden.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0042] As Figures 1 - 10 shown, a multifunctional gastric lavage bed includes: a gastric lavage bed body 1, an airbag matrix unit 3, a restraint unit 2, and a splash-proof unit 4.

[0043] As Figure 1 and Figure 2 shown, the gastric lavage bed body 1 includes a bed frame 11 and a bed board 12. A through port 13 is provided at the head region of the bed frame 11, and the bed board 12 is provided on the bed frame 11 and located behind the through port 13. In a further setting, universal wheels can be provided at the bottom of the bed frame 11 to facilitate the movement of the gastric lavage bed.

[0044] As Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown in the figure, the restraint unit 2 includes limb restraints 21 and head restraints 22; several limb restraints 21 are respectively arranged on the left and right sides of the bed frame 11. The limb restraint 21 includes a restraint seat 211 and a strap 212. The restraint seat 211 is movably arranged on the bed frame 11 in the front-back direction, and the strap 212 is arranged on the restraint seat 211; the head restraint 22 is arranged in the through opening 13. The head restraint 22 includes a bracket 221, a restraint strap 222 and a position adjustment mechanism. The bracket 221 is connected to the bed frame 11 through the position adjustment mechanism. The position adjustment mechanism is used to adjust the up-down, front-back and left-right positions of the bracket 221. The bracket 221 is an L-shaped bracket 221 with an open left side. The restraint strap 222 is arranged on the bracket 221, and the restraint strap 222 is used to restrain the patient's forehead.

[0045] Specifically, during the use of this device, when the patient lies on the bed board 12, the patient's head and neck are located at the through opening 13, and the torso is located on the bed board 12. Since during clinical gastric lavage, the patient should be in the left lateral position with the head lower than the feet to prevent the gastric lavage fluid from being aspirated into the trachea by mistake and to prevent vomitus from blocking the trachea, the bracket 221 for supporting the patient's head and neck in this device is made into an L-shaped bracket 221 with an open left side, which is convenient for tilting the patient's head to the left. At the same time, the up-down, front-back and left-right positions of the bracket 221 are adjustable, so it is convenient to adjust the spatial position of the bracket 221 according to requirements to meet the body position requirements during gastric lavage.

[0046] Since the patient is prone to restlessness during gastric lavage, in order to ensure the smooth progress of the gastric lavage process and the safety of the patient, the limb restraints 21 and head restraints 22 are provided on this gastric lavage bed. The strap 212 is arranged on the restraint seat 211 of the limb restraint 21 to tie and restrain the patient's limbs, and the restraint seat 211 can move back and forth, which is convenient to adjust the restraint position according to requirements. The head restraint 22 mainly has the restraint strap 222 arranged on the bracket 221. When the patient's head is supported on the bracket 221, the restraint strap 222 can be used to restrain the patient's forehead, effectively preventing the patient from raising the head.

[0047] As Figure 1 , Figure 2 and Figure 4 As shown in the figure, the airbag matrix unit 3 includes an air pump 31, a main pipeline 32, an airbag module and a controller 33; the bed board 12 is divided into a lumbar and dorsal region 15 in the front and a lower limb region 14 in the back. Several airbag modules are respectively arranged in the lumbar and dorsal region 15 and the lower limb region 14. Each airbag module includes an airbag 34, a branch pipeline 35, an intake valve 36 and an exhaust valve 37. The airbag 34 is fixedly arranged on the upper surface of the bed board 12. One end of the branch pipeline 35 is connected to the main pipeline 32, and the other end is connected to the airbag 34. The intake valve 36 and the exhaust valve 37 are arranged on the branch pipeline 35. The air pump 31 and the controller 33 are arranged on the bed frame 11. The air pump 31, the intake valve 36 and the exhaust valve 37 are respectively connected to the controller 33.

[0048] Specifically, a plurality of air bags 34 are provided on the bed board 12, and each air bag 34 is provided with an air inlet valve 36 and an exhaust valve 37 to individually control its own inflation and deflation. In this way, when the patient is restrained on the bed board 12, the air bags 34 in the lower limb area 14 can be alternately inflated and deflated to achieve soothing vibration, so as to reduce the restlessness of the patient. The air bags 34 in the lumbar and dorsal area 15 can be inflated to different degrees. The right air bag 34 bulges higher, and the left air bag 34 bulges lower. This can assist the patient to form a lateral inclination posture with the right side higher and the left side lower, which helps to prevent the gastric lavage fluid from being aspirated by mistake.

[0049] In practical applications, the air inlet valve 36 and the exhaust valve 37 can both use piezoelectric high-speed solenoid valves, for example. The response time of such solenoid valves is 5 ms, and the service life is 1 million times. The air bags 34 in the lower limb area 14 can use square small air bags 34, and the air bags 34 in the lumbar and dorsal area 15 can use long strip large air bags 34 extending in the front-back direction. Of course, those skilled in the art can also adopt other forms according to needs. The shape, quantity and specific arrangement of the air bags 34 are not limited here.

[0050] As Figure 2 、 Figure 5 and Figure 6 shown, the anti-splash unit 4 includes a fence 41, a protective film cover 42, a handle rod 43, a baffle 44, a support plate 45, a funnel 46 and a limiting member. The fence 41 is arranged around the upper outer periphery of the through hole 13, and the funnel 46 is arranged around the lower outer periphery of the through hole 13. The rear side wall of the fence 41 is provided with a first avoidance opening 410, the left side wall of the fence 41 is provided with a second avoidance opening 411, the upper end of the front side wall of the fence 41 is provided with a baffle 44, the baffle 44 is provided with a support plate 45, the right end of the protective film cover 42 is detachably connected to the upper end of the right side wall of the fence 41, the left end is provided with a handle rod 43, the handle rod 43 drives the protective film cover 42 to bypass the support plate 45, and then the handle rod 43 is connected to the upper end of the left side wall of the fence 41 through the limiting member. At this time, the protective film cover 42 is propped open by the support plate 45 and covers the entire upper part of the through hole 13.

[0051] Specifically, in order to prevent the gastric lavage fluid and vomit from splashing during gastric lavage of the patient, a funnel 46 is first provided on the lower side of the through hole 13 for receiving the gastric lavage fluid and vomit. A receiving bucket can be provided below the funnel 46 for receiving to prevent contamination of the ground environment. A circle of fence 41 is provided on the upper side of the through hole 13. The rear side wall of the fence 41 is provided with a first avoidance opening 410 for avoiding the patient's neck, and the left side wall of the fence 41 is provided with a second avoidance opening 411 for allowing the gastric tube to pass through normally during gastric lavage. The provided fence 41 can play a preliminary role in preventing splashing.

[0052] In addition, a protective film cover 42 is provided. The handle rod 43 can be used to bypass the support plate 45 with the protective film cover 42, and then the handle rod 43 is fixed to the upper end of the left side wall of the enclosure 41. At this time, the protective film cover 42 is propped open by the support plate 45 and covers the entire through-opening 13. In this way, the patient's head is covered under the protective film cover 42. Therefore, combined with the surrounding enclosures 41, it can effectively prevent splashing. At the same time, the protective film cover 42 and the enclosure 41 are detachably connected. After use, the protective film cover 42 can be removed for cleaning and disinfection for next use.

[0053] The provided support plate 45 is used to prop open the protective film cover 42 to a certain extent, preventing the protective film cover 42 from directly covering the patient's head and affecting normal gastric lavage.

[0054] The other structures of this device will be introduced in detail below.
