Description

Shallow for isolation ward

Technical Field

The invention relates to the technical field of carts, in particular to a cart for an isolation ward.

Background

At present, aiming at some virulent infectious diseases or infectious diseases with a certain latent period, a patient or a suspected patient needs to enter an isolation ward for treatment or observation so as to avoid massive infection of the diseases.

During the patient is in the isolation ward, three meals a day and required goods and materials all need medical personnel to provide, and medical personnel mostly adopt the handcart to carry out the granting of patient's meal and goods and materials at present. The isolation ward is now divided into a plurality of areas, such as: red zone (polluted zone), yellow zone (semi-polluted zone), green zone (clean zone) and operation zone (area where medical personnel pass or work), there are many isolation doors and many doorsills between zones. The existing cart cannot smoothly cross the threshold, and medical staff are required to forcefully lift the cart to cross the threshold when the cart passes through the threshold, so that the operation is troublesome; the process of crossing the threshold also easily causes the food or the substance on the cart to be toppled and scattered, and increases the workload of the medical staff.

Example one

As shown in fig. 1, the trolley for the isolation ward comprises a trolley body 3, wherein a storage cavity 11 is formed in the top of the trolley body 3, and a storage box 4 is installed below the storage cavity 11. Put the vertical welding in 11 bottom four corners in thing chamber and have four supporting legss 10, every supporting legs 10 bottom all rotates and is connected with a pivot 9, and equal five connecting rods 7 of fixedly connected with on every pivot 9, five connecting rods 7 free ends all rotate and are connected with a wheel 8.

Install the locking mechanism who is used for locking pivot 9 in the bin 4, combine fig. 2 to know, locking mechanism is including fixing sleeve 15 in pivot 9, has locking round pin 17 along its radial sliding connection on sleeve 15, is connected with the locking spring between locking round pin 17 and the sleeve 15, and it has the locking hole 16 that supplies locking round pin 17 male to open on the pivot 9. A wedge rod 14 is connected in the sleeve 15 in a sliding manner along the axial direction thereof, and a wedge surface matched with the wedge rod 14 is arranged on the locking pin 17. The wedge rod 14 is an iron wedge rod 14, and a return spring is connected between the wedge rod 14 and the sleeve 15.

Each connecting rod 7 is provided with a control mechanism for starting and stopping the locking mechanism, the control mechanism comprises an electromagnet (not shown in the figure) for adsorbing the wedge rod 14, the electromagnet is fixedly arranged in the storage box 4, and the electromagnet is positioned at one end of the wedge rod 14 far away from the sleeve 15. The control mechanism further comprises a delay switch 6 arranged on the connecting rod 7, and the delay switch 6 is used for controlling the electromagnet to be switched on or off. The connecting rod 7 is connected with a pressure plate 5 which can be abutted against the delay switch 6 in a sliding manner, the pressure plate 5 can be abutted against the threshold, and a control spring is connected between the pressure plate 5 and the connecting rod 7.

As can be seen from fig. 1, 2 and 3, the front side of the storage compartment 11 is vertically and slidably connected with the baffle 2. A plurality of driving teeth are integrally formed on the wedge rod 14, a gear set is rotatably mounted on the left side of the wedge rod 14, a large gear 13 in the gear set is meshed with the driving teeth, a small gear 12 in the gear set is coaxially connected with a screw rod, the screw rod is vertically in threaded connection in the vehicle body 3, and the top end of the screw rod is rotatably connected with the baffle 2.

As can be seen from the combination of fig. 1 and 3, the inner wall of the storage cavity 11 is glued with the air bag 1, and the air bag 1 is connected with an inflating mechanism for inflating the air bag 1. The inflating mechanism comprises an inflating cavity 21 vertically arranged in the inner wall of the article placing cavity 11, and the inflating cavity 21 is communicated with the air bag 1. A piston 20 is connected in the inflation cavity 21 in a sliding mode, the piston 20 is connected with a rack 19, a driving gear 18 is meshed on the right side of the rack 19, and the driving gear 18 is meshed with the baffle 2.

The specific implementation process is as follows:

the storage cavity 11 is used for placing food and materials for isolating patients, the storage box 4 is used for placing standby articles or other articles, and medical staff push the cart to each ward to distribute the food and materials for the patients. In the moving process of the cart, only one wheel 8 is in contact with the ground and serves as a walking part for moving the cart, and the rest wheels 8 are not in contact with the ground.

When the cart moves to the threshold, the pressure plate 5 on the wheel 8 in contact with the ground abuts against the threshold, the pressure plate 5 is extruded by the threshold to press the delay switch 6, the delay switch 6 controls the electromagnet to be electrified, the electromagnet pulls the wedge rod 14 to move towards the outside of the sleeve 15 (in an initial state, the locking pin 17 is inserted into the locking hole 16 under the action of the wedge rod 14, the rotating shaft 9 is locked), the locking pin 17 withdraws from the locking hole 16 under the action of the locking spring, and the rotating shaft 9 is released. The cart continues to move, when the pressing plate 5 is attached to the connecting rod 7, the connecting rod 7 can rotate clockwise around the rotating shaft 9 under the action of the threshold, and all the wheels 8 rotate clockwise. The wheel 8 on the right side of the ground, which is away from the ground, is moved over the threshold and is in contact with the ground in front of the threshold, thereby serving as a traveling member for the subsequent movement of the vehicle body 3, and allowing the vehicle body 3 to smoothly pass over the threshold.

Due to the adoption of the delay switch 6, when the wheel 8 in contact with the ground is separated from the threshold, the electromagnet cannot be powered off immediately, and the electromagnet is controlled to be powered off after the delay time set by the delay switch 6 is reached. Therefore, in practical application, the delay time of the delay switch 6 can be set according to the time of the wheel 8 crossing the threshold, so that the delay switch 6 can control the electromagnet to be powered off after the wheel 8 crosses the threshold.

When the wedge rod 14 moves towards the outside of the sleeve 15, the large gear 13 can be driven to rotate, the large gear 13 drives the small gear 12 to rotate, and the small gear 12 drives the screw rod to rotate. Because lead screw threaded connection is in automobile body 3, so the lead screw can the rebound in the pivoted to drive baffle 2 rebound (baffle 2 is accomodate in automobile body 3 under the initial condition). Therefore, the baffle 2 extends out of the vehicle body 3 and shields the front side of the storage cavity 11 to protect articles and prevent the articles in the storage cavity 11 from falling out. Due to the adoption of the gear set, the baffle 2 can be accelerated when moving, and the baffle 2 can be rapidly moved to the front side of the object placing cavity 11.

The baffle 2 can drive the rack 19 to move downwards through the driving gear 18 while moving upwards, and the rack 19 drives the piston 20 to move towards the inside of the inflation cavity 21, so that the gas in the inflation cavity 21 is extruded into the airbag 1, and the airbag 1 is inflated. After the size of the air bag 1 is increased, the hard collision between the articles and the inner wall of the article placing cavity 11 can be reduced, so that the articles are prevented from being damaged. Under the condition of full of articles, the volume of the air bag 1 is increased, and an acting force for extruding the articles to the middle of the storage cavity 11 can be provided for the articles, so that the articles lean more tightly, and the probability of loosening and toppling of the articles is reduced.

Example two

The difference between this embodiment and the first embodiment lies in, it has the slipmat to put 11 diapalls rubberizing joints in the thing chamber, sets up the slipmat and can avoid article to skid and cause and empty.
