Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an operating cart for static preparation in a treatment room. Background Technology

[0002] In hospital intravenous medication preparation centers (PIVAS) and various treatment rooms, aseptic medication preparation is a core aspect of ensuring patient medication safety. Currently, medical staff often use ordinary treatment carts for medication preparation and preparation. However, traditional treatment carts have significant shortcomings: their work surface height is fixed, which cannot be adapted to medical staff of different heights or operating habits, and prolonged bending over can easily lead to occupational fatigue and strain. At the same time, the open or simply covered trash cans on the cart cannot effectively isolate medical waste (such as ampoules, medicine bottles, syringes, etc.) generated during the preparation of special drugs such as cytotoxic drugs and antibiotics, posing a risk of aerosol release or cross-contamination, which may threaten the health of medical staff.

[0003] Therefore, there is an urgent need for an operating cart specifically designed for intravenous preparation and treatment environments, integrating a freely adjustable work surface, with ergonomic design to improve operating comfort and efficiency; and crucially, it is equipped with a highly efficient and airtight waste bin shell structure, realizing the immediate and safe isolation of medical waste, fundamentally optimizing the clinical working environment, protecting the occupational health and safety of operators, and further improving the aseptic standards and quality control level of intravenous medication preparation. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing static matching operation vehicle mentioned in the background art cannot adjust the height of the operating platform according to the height, and at the same time, the vehicle body does not have a garbage can shell structure to isolate garbage.

Detailed Implementation

[0018] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0019] Definition: In this embodiment, the entire operating vehicle is placed on the ground, with the direction the operating vehicle points towards the ground being downward and the opposite direction being upward.

[0020] like Figure 1 , 6 As shown, a treatment room sterilization operation cart includes a base 1, an operation table 2, a lifting mechanism 3, and a waste container 4. The base 1 is placed on the ground, the lifting mechanism 3 is located on the base 1, the operation table 2 is located on the base 1 and connected to the lifting mechanism 3, and the waste container 4 is located on the base 1.

[0021] The main function of the base 1 is to provide load-bearing and easy movement functions for the entire device, which is placed on the ground via the base 1.

[0022] The main function of operating table 2 is to provide a medication preparation environment for medical staff, who prepare medications on the table surface of operating table 2.

[0023] The main function of the lifting mechanism 3 is to adjust the height of the operating platform 2 so as to adjust the appropriate height according to the height and operating habits of medical staff, and avoid the threat to the health of medical staff from bending over for a long time.

[0024] The main function of the waste casing 4 is to isolate waste and prevent the risk of cross-contamination caused by certain special medical waste.

[0025] like Figure 1 As shown, the base 1 is a hollow steel cylinder. Multiple sets of support rods are evenly spaced on the outer surface of the bottom end of the cylinder. Under the support rods are casters 11 with locking function, which facilitates the movement of the operating vehicle in different directions.

[0026] like Figure 4 , 5 As shown, the waste casing 4 includes an outer shell 41, a push door 42, a passage door 43, a lock bar 44, and a return spring 45. The outer shell 41 is a rectangular shell made of steel. Two rectangular holes of different sizes, which are not connected to each other, are penetrating one side surface of the outer shell 41. The upper part of the smaller hole is rotatably connected to the steel push door 42 via a hinge. The horizontal length of the larger hole is the same as the horizontal length of the outer shell 41, and the vertical height is less than the vertical height of the outer shell 41. One side of the larger hole is rotatably connected to one end of the steel passage door 43 via a hinge. The passage door 43 is connected to a sliding door. A rectangular mounting groove 65 is provided above the other end of the passage door 43. The length of the mounting groove 65 is perpendicular to the ground. The mounting groove 65 is embedded in the interior of the passage door 43. One end of the groove passes through the top of the passage door 43. A limiting hole 47 with a vertical length slightly smaller than the mounting groove 65 is provided on the vertical side surface of the mounting groove 65. The limiting hole 47 passes through the surface of the passage door 43 and communicates with the mounting groove 65. The upper end of the limiting hole 47 is not on the same horizontal line as the upper end of the mounting groove 65. The locking bar 44 is a rectangular plastic block with a beveled end. It is placed in the mounting groove 65. The locking bar 44 protrudes outward from the limiting hole 47 and passes through the limiting hole 47 to the outside. One end of the return spring 45 abuts against the inner wall of the mounting groove 65, and the other end is fixedly connected to the other end of the beveled locking bar 44. The locking bar 44 and the return spring 45 work together to block and interfere with the passage door 43 by acting on the outer shell 41, thereby driving the passage door 43 to open and close.

[0027] In order to prevent the lock bar 44 from interfering with the passage door 43, a corresponding locking hole is provided on the outer shell 41.

[0028] The closing of the passage door 43 is achieved as follows: In its natural state, the locking bar 44, through the action of the return spring 45, pushes the inclined end of the locking bar 44 a certain distance along the edge of the passage door 43 along the limiting hole 47, and will not be pushed away from the passage door 43 under the action of the limiting hole 47. At this time, the passage door 43 is pushed to rotate along the rotational connection with the outer shell 41. Due to the special shape of the inclined end of the locking bar 44, when the passage door 43 is pushed to contact the outer shell 41, it will squeeze the locking bar 44, causing the return spring 45 to compress. Then, under the reset of the return spring 45, the locking bar 44 is embedded into the corresponding locking hole opened on the outer shell 41, thereby blocking and interfering with the passage door 43. At this time, the passage door 43 is closed.

[0029] The passage door 43 is opened as follows: by pressing down on the protrusion on the locking bar 44, the locking bar 44 compresses the return spring 45, causing the locking bar 44 to leave the locking hole of the outer casing 41, thus releasing the obstruction and interference of the locking bar 44 on the passage door 43. Then, the passage door 43 is pulled back and rotated along the rotational connection with the outer casing 41, thereby opening the passage door 43.

[0030] To facilitate the opening and closing of the passage door 43, a door handle is fixedly connected to the other end of the passage door 43 at the rotatable connection with the outer casing 41, so as to facilitate opening and closing the passage door 43, and the thumb can reach the protrusion on the lock bar 44 when holding the door handle.

[0031] In order to isolate the garbage in the garbage shell 4, an existing garbage bin product is placed inside the shell 41 for placing garbage, and the garbage bin is replaced through the passage door 43.

[0032] To enhance the isolation effect of garbage, garbage is placed into the garbage bin inside the outer shell 41 through the push door 42. After the garbage is placed, the push door 42 closes automatically under the action of gravity to prevent infection.

[0033] To facilitate the use of the waste container 4, the push door 42 is located above the passage door 43. The height of the push door 42 is slightly higher than the height of the waste container, and the push door 42 and the passage door 43 face the position where medical staff stand when dispensing medicine.

[0034] To facilitate the connection between the waste casing 4 and the base 1, a cuboid mounting plate is fixed to the lower cylindrical part of the base 1. The cylindrical base 1 penetrates the central area of ​​the mounting plate. The waste casing 4 has two parts located on both sides of the mounting plate. The bottom of the outer casing 41 is fixedly connected to the mounting plate.

[0035] To facilitate the disposal of sharp objects after medication, a rectangular shelf 12 is fixed on the outer surface of the cylindrical base 1, slightly higher than the waste shell 4. The cylindrical base 1 penetrates the central area of ​​the shelf 12, and there are protruding baffles around the shelf 12, on which a sharp object box can be placed.

[0036] like Figure 1 , 3 As shown, the operating table 2 is made of rectangular steel. The upper surface of the operating table 2 has baffles protruding from three directions, and the lower surface of the operating table 2 has a cylindrical protrusion protruding from the center. Several shell-shaped rectangular steel storage baskets 21 are fixed on the upper surface. The upper surface is open and can hold medicine bottles, cotton swabs, etc. A handrail is fixed on one side of the operating table 2 for easy pushing by medical staff. A drawer 23 is opened on the operating table 2. The space in the drawer 23 is divided by multiple sets of baffles and corresponding slides, and the size of the space can be adjusted according to actual needs.

[0037] like Figure 2 As shown, in order to expand the usable area of ​​the workbench 2, a rectangular steel plate is slidably connected to the top of the drawer 23 using slide rails and sliders, and is used as a secondary workbench 242. It can be pulled out when in use.

[0038] To increase the utilization rate of the operating table 2, a box 22 is fixedly placed on the baffle on the opposite side of the handrail. It can hold disinfectant and small sharps containers. At the same time, a timer and a desk lamp can be placed at the bend of the baffle for the convenience of medical staff.

[0039] like Figure 6 As shown, the lifting mechanism 3 includes a worm 31, a worm wheel 32, and a lead screw 33. One end of the lead screw 33 is rotatably connected to the bottom surface of the cylindrical hollow part of the base 1 through a bearing, and the other end extends upward. A cylindrical protrusion on the lower surface of the operating table 2 is screwed onto this end of the lead screw 33. A worm wheel 32 is sleeved at the vertical center of the lead screw 33, and a worm 31 is fitted on the outer surface of the worm wheel 32. One end of the worm 31 at the hollow part of the base 1 is rotatably connected to a cylindrical protrusion on the inner wall of the cylindrical base 1 through a bearing. One end extends outside the base 1 and bends a certain distance to form a crank. Rotating the crank makes the lifting mechanism 3 cooperate with the operating table 2 to realize the lifting of the operating table 2.

[0040] The lifting mechanism 3 works in conjunction with the operating platform 2 to achieve the lifting of the operating platform 2 as follows: turning the crank drives the worm gear 31 to rotate, which in turn drives the worm wheel 32 to rotate. Since the worm wheel 32 is sleeved on the lead screw 33, it drives the lead screw 33 to rotate. Since one end of the operating platform 2 is screwed onto the lead screw 33, when the lead screw 33 rotates, it drives the operating platform 2 to rise along the threaded opening. When it rotates in the opposite direction, it drives the operating platform 2 to fall.

[0041] In order to achieve the cooperation between the lifting mechanism 3 and the operating table 2, the bottom diameter of the cylindrical protrusion on the lower surface of the operating table 2 is smaller than the bottom diameter of the cylindrical base 1. Furthermore, the inner recess and the outer protrusion are respectively located on both sides of the contact surface between the two. The protrusion is embedded in the groove, so that when the lead screw 33 rotates, it will not cause the operating table 2 to rotate.

[0042] To facilitate the installation of different components in the lifting mechanism 3, an installation port is provided on the base 1, dividing the base 1 into two halves in the horizontal direction. After the components are installed, the installation port is sealed by welding.

[0043] After the operating platform 2 is raised by the lifting mechanism 3, the operating platform 2 will be pulled downward by gravity. Due to the special structure of the worm gear 32 and worm 31, the worm gear 32 sleeved on the surface of the lead screw 33 will not rotate. Therefore, the operating platform 2 will not descend under the influence of gravity. It can only descend by controlling the rotation direction of the worm 31, thus realizing the self-locking function of the operating platform 2 after it rises.

[0044] The working principle and usage process of this utility model are as follows: Medical staff need to use this operating cart to prepare medications. According to their actual height, they can turn the crank to adjust the height of the operating table 2. By pulling out the extended operating table 2, the operating surface can be enlarged to facilitate medication preparation. At the same time, the surface of the operating table 2 is fixed with a storage basket 21 for placing ampoules and other medicine bottles. The storage box 22 on the side of the operating cart can hold daily-use disinfectant and sharps boxes. Meanwhile, the drawer 23 can store various medicine bottles for use. After the medication is prepared, the medical waste is placed into the trash can inside the waste shell 4 through the push door 42. The trash can can be removed through the passage door 43. The waste shell 4 can isolate the waste to prevent infection. After the medication is prepared, the operating cart is pushed to the patient's ward by the handrail to administer the medication to the patient.

[0045] The lifting mechanism 3 can accommodate medical staff of different heights or operating habits, avoiding occupational fatigue and strain caused by prolonged bending. The waste casing 4 can isolate waste of special drugs, avoiding potential threats to the health of medical staff. The various small components can increase the efficiency of medical staff in using the operating cart, protect the occupational health and safety of medical staff, and further improve the aseptic standards and quality control level of intravenous drug preparation.

[0046] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
