Description

Technical Field

[0001] The present invention relates to the technical field of special vehicles, in particular to an ambulance for specific diseases. Background Art

[0002] Specific disease ambulances are ambulances designed and equipped specifically for certain types of diseases or emergency medical conditions. The main difference between this type of ambulance and ordinary ambulances is that they are equipped with more specialized medical equipment, medicines and first aid facilities according to the special needs of specific diseases, so that they can respond more effectively to the patient's specific condition.

[0003] The more common ambulances for specific diseases are stroke vehicles, chest pain vehicles and trauma vehicles. Taking the chest pain vehicle as an example, the vehicle is equipped with mobile digital X-ray photography, electrocardiograph, bedside ultrasound machine, rapid bedside testing equipment, etc. The configuration of these devices allows medical staff to quickly and effectively utilize the equipment in the vehicle, especially with the information construction, to achieve rapid treatment of diseases in the vehicle, greatly shortening the patient's life-saving time.

[0004] At present, when loading patients, ambulances for specific diseases generally guide the movable stretcher treatment bed on the vehicle through the ground rails laid in the vehicle, so that the treatment bed slides into the vehicle, loads the patient and sends him to the hospital. Since the treatment bed is not fixed, it is very easy for the treatment bed to move in the vehicle during the driving process, affecting the treatment of the patient. In order to avoid this situation, some treatment beds are equipped with foot brakes on the bottom wheels. However, in the actual process of loading patients, when the treatment bed enters the ambulance, the space for medical staff to walk in the vehicle is very narrow. Therefore, it is very inconvenient to walk in the vehicle and operate the foot brake of the treatment bed after loading the treatment bed. Summary of the invention

[0005] The present invention is intended to provide an ambulance for specific diseases to solve the problem that the diagnosis and treatment bed is easily moved in the existing ambulance during driving, thus affecting the treatment of patients.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a specific disease ambulance, comprising a vehicle body and a movable diagnosis and treatment bed, the vehicle body is provided with a driving cab and a diagnosis and treatment room, an end of the diagnosis and treatment room away from the driving cab is provided with an openable and closable rear door, a floor rail is laid in the diagnosis and treatment room, the floor rail has a slide groove for the diagnosis and treatment bed to slide, the diagnosis and treatment bed comprises a bed body and a bed wheel arranged at the bottom of the bed body, the bed wheel and the floor rail are slidably matched, and the bed wheel can slide out of the diagnosis and treatment room from the end of the floor rail close to the rear door; the bed wheel comprises a front bed wheel and The rear bed wheel and the side wall of the slide groove are provided with an extrusion protrusion near the cab; the front bed wheel includes a rotating wheel and a positioning wheel, the rotating wheel and the bed body can rotate relatively, and the rotating wheel is an annular wheel; the positioning wheel is slidably connected to the bed body, and a reset member is connected between the positioning wheel and the bed body, the positioning wheel is located in the hollow circle of the rotating wheel, and the positioning wheel is provided with a protrusion protruding from the rotating wheel, the protrusion has a wedge surface that can be abutted against the extrusion protrusion, and the protrusion is provided with a braking member that can be abutted against the end face of the rotating wheel.

[0007] The principle of this solution is as follows: in this solution, the front wheel of the diagnosis and treatment bed is set as two structures, namely a rotating wheel and a positioning wheel, and a wedge surface is set on the positioning wheel. When the front wheel slides in the slide groove of the ground rail and contacts the extrusion protrusion, the extrusion protrusion squeezes the positioning wheel, causing the positioning wheel to slide relative to the vehicle body and causing the brake member on the protrusion to abut against the rotating wheel. At this time, the brake member brakes the rotating wheel, making the rotating wheel unable to rotate. At the same time, under the influence of the reset force applied by the reset member, the protrusion of the positioning wheel applies a certain reverse extrusion force to the extrusion protrusion, thereby causing the protrusion to abut against the extrusion protrusion, and tensioning the front wheel in the slide groove of the ground rail. In this way, even when the rear wheel of the diagnosis and treatment bed is not braked and locked, the diagnosis and treatment bed is not easy to move in the vehicle only by braking and tensioning the front wheel, thereby ensuring the stability of the position of the diagnosis and treatment bed in the vehicle and making it more convenient for medical staff to examine patients. Moreover, with the wheel structure in the present solution, when the diagnosis and treatment bed needs to be pulled out of the vehicle, it is only necessary to pull the diagnosis and treatment bed with force to overcome the squeezing force between the protrusion and the squeezing protrusion to separate the protrusion from the squeezing protrusion. The protrusion will be reset under the action of the reset member and the braking of the rotating wheel by the brake member will be cancelled, so that the rotating wheel can slide smoothly in the ground rail and the diagnosis and treatment bed can be pulled out smoothly without the need to operate the foot brake separately, which is more convenient to use.

[0008] The advantages of this solution are:

[0009] 1. By squeezing the positioning wheel with the squeezing protrusion, the brake part brakes the rotating wheel, making it difficult for the diagnosis and treatment bed to move in the car, making it more convenient for medical staff to examine the patient;

[0010] 2. The braking operation of the rotating wheel is automatically performed by squeezing the positioning wheel with the squeezing protrusion, without the need for manual braking. The operation is more convenient and avoids the tedious process of medical staff operating the foot brake of the treatment bed in the narrow space inside the car;

[0011] 3. The protruding part of the directional wheel exerts an extrusion convexity and an anti-extrusion force, so that the bed wheel can be more effectively fixed in the ground rail, thereby enhancing the fixing effect of the diagnosis and treatment bed;

[0012] 4. When taking out the diagnosis and treatment bed, you only need to pull the diagnosis and treatment bed hard to separate the protrusion of the positioning wheel from the extrusion protrusion. There is no need to operate the braking structure separately, and the operation is more convenient when the brake is cancelled.

[0013] Preferably, as an improvement, each rotating wheel is provided with two positioning wheels, the two positioning wheels are symmetrically distributed on both sides of the rotating wheel, the two positioning wheels can move towards or away from each other, and two opposite extrusion protrusions are provided on the side wall of the slide groove, and the two positioning wheels can respectively abut against the two extrusion protrusions.

[0014] Through the above scheme, the two positioning wheels can simultaneously abut against the extrusion protrusions on the side walls of the slide groove, thereby enhancing the braking and fixing effect of the front wheels, and can further ensure the stability of the treatment bed in the ambulance.

[0015] Preferably, as an improvement, an iron ring is provided on the inner wall of the rotating wheel, and the center of the iron ring coincides with the center of the rotating wheel; a main locking device is also provided in the treatment room, and the main locking device includes a screw fixed in the treatment room, and the screw extends along the width direction of the vehicle body; a sliding sleeve is sleeved on the screw and threadedly connected, a sliding arm is fixed on the sliding sleeve, and a latch is fixed on the sliding arm, and the latch is a magnet; there is a gap between the rotating wheel and the positioning wheel, the latch is arranged opposite to the gap, and the latch can be inserted into the gap and magnetically fixed to the iron ring.

[0016] Through the above scheme, the main locking device is used to lock the rotating wheel. When the lead screw works and drives the sliding sleeve to move, the sliding sleeve drives the bolt to move through the sliding arm, so that the bolt is inserted into the gap between the rotating wheel and the positioning wheel, and is adsorbed and fixed on the iron ring on the inner wall of the rotating wheel, thereby locking the rotating wheel through the magnetic attraction between the bolt and the iron ring. At the same time, since the brake member is against the rotating wheel at this time, that is, the brake member blocks a part of the annular gap between the rotating wheel and the positioning wheel, when the rotating wheel intends to rotate and the bolt slides relative to the iron ring in the gap, the brake member can prevent the bolt from sliding, thereby playing a role in rotating the rotating wheel. The rotating wheel cannot rotate in place in the ground rail, nor can it move forward and backward, thereby enhancing the braking effect on the rotating wheel, and further ensuring the stability of the diagnostic bed in the vehicle. The use of magnets and iron sheets for magnetic fixation is compared to the traditional method of setting a socket on the rotating wheel and locking the rotating wheel by inserting the bolt into the socket. There is no need to consider whether the bolt is aligned with the socket. When the bolt is used to fix the rotating wheel, the operation is more convenient.

[0017] Preferably, as an improvement, there are multiple latches.

[0018] Through the above solution, multiple pins can be magnetically fixed on the iron ring at the same time, which improves the braking effect on the rotating wheel and further strengthens the fixing effect on the treatment bed.

[0019] Preferably, as an improvement, the latch is retractable, and comprises a fixed pin fixedly connected to the sliding arm and a sliding pin slidably connected to the fixed pin, and a reset member is connected between the fixed pin and the sliding pin.

[0020] According to the above scheme, when the bolt is inserted into the gap, if a bolt is not facing the gap but facing the brake part, the bolt will abut against the brake part and contract itself to ensure that other bolts can be smoothly inserted into the gap and brake the rotating wheel, thus avoiding the situation that the bolt facing the brake part is stuck by the brake part and other bolts cannot be inserted into the gap. When the bolt is away from the brake part, the reset part can make the sliding pin slide relative to the fixed pin, thereby restoring the original length of the bolt.

[0021] Preferably, as an improvement, the lead screw is a double-ended lead screw, both ends of which are sleeved and threadedly connected with sliding sleeves.

[0022] Through the above scheme, the double-ended screw is used to drive the two sleeves to work simultaneously, so that the two front wheels can be braked at the same time.

[0023] Preferably, as an improvement, an auxiliary locking device is also provided in the treatment room, the auxiliary locking device includes a brake chuck slidably arranged in the vehicle body, a wedge block which can be inserted between the rotating wheel and the ground rail is fixed on the brake chuck, and the wedge block and the sliding arm are respectively located on both sides of the rotating wheel; the brake chuck is provided with an iron block which can be fixed by magnetic attraction of a pin.

[0024] Through the above scheme, the auxiliary locking device is used to assist the main locking device in locking the rotating wheel. When the latch is inserted into the gap, the latch attracts the brake chuck to move toward one side of the rotating wheel, and the brake chuck drives the wedge to move, so that the wedge moves and is inserted between the rotating wheel and the ground rail, thereby braking and locking the rotating wheel in the front and rear directions to ensure the stability of the diagnosis and treatment bed.

[0025] Preferably, as an improvement, a reset member is also connected between the brake chuck and the vehicle body.

[0026] Through the above scheme, when the braking and locking of the rotating wheel are released and the latch and the brake chuck are moved away from the rotating wheel, the reset member can move the brake chuck and the wedge to reset, thereby moving the wedge away from the rotating wheel so that the diagnostic and treatment bed can slide and be removed on the floor rail.

[0032] The following is further described in detail through specific implementations, but the implementation of the present invention is not limited thereto. Unless otherwise specified, the technical means used in the following implementations are conventional means well known to those skilled in the art; the experimental methods used are all conventional methods; the materials, reagents, etc. used can all be obtained from commercial channels.

[0034] Example 1

[0035] The specific disease ambulance in this embodiment includes a vehicle body and a movable diagnosis and treatment bed, such as Figure 1 As shown, the vehicle body is provided with a driving cab 1 and a treatment room 2. An openable and closable rear door 3 is provided at one end of the treatment room 2 away from the driving cab 1. A floor rail 4 is laid in the treatment room 2. The floor rail 4 has a slide groove 5 for sliding a treatment bed. The slide groove 5 is used to guide the moving direction of the treatment bed so that the treatment bed can move from the rear door 3 to the side of the driving cab 1 and enter the treatment room 2 in a predetermined direction.

[0036] Combination Figure 2 As shown, the diagnosis and treatment bed includes a bed body and a bed wheel arranged at the bottom of the bed body, the bed wheel is slidably matched with the ground rail 4, and the bed wheel can slide out of the diagnosis and treatment room 2 from the end of the ground rail 4 close to the rear door 3. The bed wheel includes a front bed wheel and a rear bed wheel, and a squeezing protrusion 8 is provided on the side wall of the slide 5 near the cab 1.

[0037] The front bed wheel includes a rotating wheel 6 and a positioning wheel 7. The rotating wheel 6 and the bed body can rotate relative to each other. The rotating wheel 6 is an annular wheel. The positioning wheel 7 is slidably connected to the bed body, and a reset member 9 is connected between the positioning wheel 7 and the bed body. The positioning wheel 7 is located in the hollow circle of the rotating wheel 6, and the positioning wheel 7 is provided with a protrusion 10 protruding from the rotating wheel 6. The protrusion 10 has a wedge surface 11 that can abut against the extrusion protrusion 8. The protrusion 10 is provided with a brake member 12 that can abut against the end face of the rotating wheel 6. The brake member 12 can brake and rotationally lock the rotating wheel 6 by contacting and rubbing the end face of the rotating wheel 6. Specifically, the connection between the rotating wheel 6 and the positioning wheel 7 and the bed body in this embodiment is as follows: Figure 2 As shown, the bed body is provided with a bracket 13, and the positioning wheel 7 is slidably connected to the bracket 13. The specific sliding connection method is: a clamping protrusion 14 is provided on the bracket 13, and a connecting groove 15 is provided on the inner wall of the positioning wheel 7. The clamping protrusion 14 is clamped in the connecting groove 15 and can slide along the connecting groove 15. At the same time, the rotating wheel 6 is rotatably connected to the bracket 13. The specific rotation connection method is that a wheel frame 16 is provided on the bracket 13, and the wheel frame 16 and the rotating wheel 6 are rotatably matched through a bearing. The reset member 9 between the positioning wheel 7 and the bracket 13 is a compression spring.

[0038] At the same time, if Figure 2 As shown, each rotating wheel 6 is provided with two positioning wheels 7, and the two positioning wheels 7 are symmetrically distributed on both sides of the rotating wheel 6. The two positioning wheels 7 can move towards or away from each other, and two opposite extrusion protrusions 8 are provided on the side wall of the slide groove 5. The two positioning wheels 7 can respectively abut against the two extrusion protrusions 8.

[0039] In specific implementation, after the diagnosis and treatment bed enters the vehicle body, the front wheels and the rear wheels successively enter the slide groove 5 of the ground rail 4, and slide along the slide groove 5 toward the side of the cab 1. When the front wheel travels to the extrusion protrusion 8, the extrusion protrusion 8 squeezes the wedge surface 11 of the protrusion 10, so that the positioning wheel 7 slides along the bracket 13 and enters the rotating wheel 6, and the brake 12 on the positioning wheel 7 follows the movement and abuts against the end surface of the rotating wheel 6, so that the brake 12 performs friction braking and locking on the rotating wheel 6, preventing the rotating wheel 6 from rotating at will and causing the diagnosis and treatment bed to move in the vehicle body, which is convenient for medical staff to check and operate. In this process, the compression spring between the positioning wheel 7 and the bracket 13 is compressed, and the compression spring causes the positioning wheel 7 to reversely squeeze the extrusion protrusion 8, so that the positioning wheel 7 is tensioned and fixed in the slide groove 5, thereby enhancing the fixing effect of the front wheel of the diagnosis and treatment bed.

[0040] When the diagnosis and treatment bed needs to be taken out of the vehicle body, the operator only needs to pull the diagnosis and treatment bed along the slide groove 5 to separate the extrusion protrusion 8 and the positioning wheel 7. At this time, the brake member 12 on the positioning wheel 7 is away from the rotating wheel 6, thereby releasing the brake on the rotating wheel 6, so that the diagnosis and treatment bed can be pulled freely.

[0041] Example 2

[0042] This embodiment is based on the embodiment 1. Figure 3 As shown, an iron ring 17 is provided on the inner wall of the rotating wheel 6, and the center of the iron ring 17 coincides with the center of the rotating wheel 6. A main locking device is also provided in the treatment room 2, and the main locking device includes a lead screw 18 fixed in the treatment room 2, the lead screw 18 is driven by a motor, and the lead screw 18 extends along the width direction of the vehicle body; a sliding sleeve 19 is sleeved and threadedly connected on the lead screw 18, a sliding arm 20 is bolted to the sliding sleeve 19, and a latch 21 is bolted to the sliding arm 20, and the latch 21 is a magnet.

[0043] There is a gap 22 between the rotating wheel 6 and the positioning wheel 7, and the latch 21 is arranged opposite to the gap 22, and the latch 21 can be inserted into the gap 22 and fixed on the iron ring 17 by magnetic attraction. There are multiple latches 21, and the multiple latches 21 are distributed in a circular array, and the latches 21 are retractable. Specifically, the latch 21 includes a fixed pin fixedly connected to the sliding arm 20 and a sliding pin slidably connected to the fixed pin. The telescopic principle is consistent with the existing telescopic rod, which will not be repeated here. A reset member 9 is connected between the fixed pin and the sliding pin. The reset member 9 in this embodiment is a compression spring.

[0044] In actual application, the screw 18 can also be a double-headed screw 18, which is driven by a dual-axis motor to work synchronously. Both ends of the double-headed screw 18 are sleeved and threaded with a sliding sleeve 19 to respectively connect a set of pins 21 for synchronous braking of the two front bed wheels.

[0045] When this embodiment is used in practice, after the extrusion protrusion 8 squeezes the positioning wheel 7 so that the brake member 12 brakes and locks the rotating wheel 6, the motor is started, and the motor drives the lead screw 18 to work, so that the sliding sleeve 19 drives the sliding arm 20 to move, so that the latch 21 enters the gap 22 between the rotating wheel 6 and the positioning wheel 7. Since the latch 21 is a magnet, it is magnetically fixed to the iron ring 17 to further lock the rotating wheel 6 and prevent the rotating wheel 6 from rotating. At the same time, when the rotating wheel 6 wants to rotate, the latch 21 and the iron ring 17 will move relative to each other, and the latch 21 will move in the gap 22. However, since the brake member 12 blocks the outer side of the end of the rotating wheel 6, the brake member 12 will prevent the latch 21 from continuing to move in the gap 22, thereby limiting the position of the latch 21 in the gap 22, thereby enhancing the locking effect on the front wheel.

[0046] Example 3

[0047] like Figure 4 and Figure 5As shown, on the basis of the above-mentioned embodiments, this embodiment is further provided with an auxiliary locking device in the treatment room 2, and the auxiliary locking device comprises a brake chuck 23 slidably arranged in the vehicle body, and a wedge 24 which can be inserted between the rotating wheel 6 and the ground rail 4 is bolted to the brake chuck 23. There are two wedges 24 in this embodiment, and the two wedges 24 are respectively used to insert into the front and rear sides of the rotating wheel 6 to limit the rotating wheel 6 in the front and rear directions. The wedge 24 and the sliding arm 20 are respectively located on both sides of the rotating wheel 6; the brake chuck 23 is provided with an iron block which can be fixed by the pin 21 by magnetic attraction. A reset member 9 is also connected between the brake chuck 23 and the vehicle body, and the reset member 9 adopts a spring.

[0048] In specific implementation, combined with Figure 5 As shown, when the latch 21 is inserted into the gap 22 to lock the rotating wheel 6, the latch 21 will attract the brake chuck 23 while the magnet is fixed on the iron ring 17, so that the brake chuck 23 drives the wedge block 24 to move, so that the wedge block 24 is inserted between the ground rail 4 and the rotating wheel 6, and the front and rear directions of the rotating wheel 6 are restricted, thereby further achieving the purpose of locking the position of the rotating wheel 6.

[0049] Of course, in actual application, in order to ensure the movement effect of the brake chuck 23, a driving device of the brake chuck 23 can also be separately provided, and the brake chuck 23 can be moved and driven by an external driving device, such as a motor.

[0050] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
