Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an intelligent medical treatment vehicle based on double weighing check. BACKGROUND

[0002] In the clinical practice of the operating room, the preoperative preparation and postoperative counting of surgical instruments and dressings is a crucial and tedious process, which is directly related to the safety and efficiency of the operation.

[0003] Currently, the mainstream method still highly depends on manual visual counting and manual recording by medical staff, which has the following significant defects. First, the efficiency is low, which occupies valuable preoperative and postoperative time, and medical staff needs to repeatedly check a large number of instruments and dressings of various types, which prolongs the non-direct medical operation time of the operation. Second, the risk of human error is high. In long-time, high-intensity or night emergency operations, factors such as personnel fatigue and distraction can easily lead to missing, miscounting or repeated counting, especially for small dressings such as gauze and gauze balls, which change in shape and color after being stained with blood and tissue fluid, and are difficult to accurately identify and count by traditional visual methods, becoming one of the main risk sources of instruments left in the patient's body. In addition, the existing process separates the counting and contaminated instrument processing. After the operation, the used contaminated instruments need to be manually collected by the nurses, transferred to the dirt basin and sent out of the operating room. This process not only increases the risk of medical staff contacting the contaminated source and the additional operation burden, but also has potential risks of contamination exposure and cross infection. Therefore, the operating room urgently needs an intelligent medical treatment vehicle that can achieve accurate and automatic checking and in-situ closed integrated processing of contaminated instruments to improve the safety and management efficiency of the operation.

Detailed Implementation

[0045] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0046] like Figure 1 As shown, this intelligent medical treatment cart includes a mobile base 100 with wheels and a vehicle body 101 fixed on the mobile base 100. The top of the vehicle body 101 has an opening for loading and unloading instruments. A display screen 102 and an audible and visual alarm 103, serving as a human-machine interface, are installed on the upper part of the vehicle body 101. A lifting and weighing unit is installed inside the vehicle body 101. This unit includes a first telescopic drive component 200, which is fixed to the mobile base 100. Its telescopic end is rotatably connected to a load-bearing bracket 201. A damping device can be installed between the load-bearing bracket 201 and the first telescopic drive component 200. A guide rail 202 is mounted on the bracket 201, and a sliding member 203 slides in cooperation with the guide rail 202. An electronic scale 204 is mounted on the sliding member 203. The weighing platform of the electronic scale 204 is equipped with a magnetic block 205. The instrument tray 206 is magnetically attracted to the magnetic block 205. In addition, an image acquisition unit, namely an industrial camera 600 with a lens aimed at the instrument tray 206, is also installed on the upper part of the vehicle body 101. The first telescopic drive member 200, the dynamic weighing module integrated in the electronic scale 204, the human-machine interaction unit, and the industrial camera 600 are all electrically connected to the data processing and control module.

[0047] Working principle: in the preoperative preparation, the data processing and control module controls the first telescopic drive 200 to extend, lifts the tray 206 carrying the instruments to a convenient position, in the process, the electronic scale 204 accurately weighs the total weight of the instruments and records it as the first weight value W1, the industrial camera 600 synchronously shoots the image and generates the first instrument list, the data is stored in real time to establish the check baseline; after the operation, when all the used instruments are put back on the tray 206, the electronic scale 204 will weigh again and record the total weight after returning as the third weight value W3, the industrial camera 600 will also shoot the image again and generate the second instrument list; the weight W3 collected after returning and the image list, together with the weight W2 recorded after use in the operation and the preoperative list, are compared and decided by the control module.

[0048] As shown in Figure 1 and Figure 6 , it includes a dirt disposal cabin 300 and a set of moisturizing and disinfecting units, the dirt disposal cabin 300 is movably arranged inside the vehicle body 101, located directly below the instrument tray 206, it is connected to a fixed mounting plate 104 in the vehicle body through a set of independent lifting mechanism, by operating the mechanism, the dirt disposal cabin 300 can be lowered, so that the bottom of the drain port is aligned with and tightly connected to the inlet of the waste liquid tank 408 fixedly installed on the mobile chassis 100, the moisturizing and disinfecting units are electrically connected with the data processing and control module, used for spraying moisturizing liquid or disinfecting liquid to the used instruments stored in the dirt disposal cabin 300.

[0049] Working principle: after the intelligent check is completed, the control module instructs the instrument tray 206 to lower, moves the instruments into the dirt disposal cabin 300 to realize physical isolation, then starts the moisturizing and disinfecting unit to spray, prevents the contamination from drying to facilitate subsequent cleaning, the sprayed waste liquid is discharged and collected through the sealed pipeline formed by the cabin and the waste liquid tank 408, the whole process eliminates the pollution leakage.

[0050] As shown in Figure 2 , it also includes at least two guide rods 301 vertically fixed on the mounting plate 104, the dirt disposal cabin 300 is slidably connected with the mounting plate 104 through the guide rods 301, a threaded sleeve 302 is fixedly installed on the dirt disposal cabin 300, a vertical lead screw 303 is screwed into the threaded sleeve 302, the lead screw 303 penetrates through the mounting plate 104 and is rotatably connected with the mounting plate 104, the end of the lead screw 303 is connected with a driving assembly, the assembly includes a right angle actuator 304 connected with the lead screw 303, a transmission shaft 305 connected with the horizontal output end of the right angle actuator 304, and a handle 306 arranged outside the vehicle body 101 for operation.

[0051] Working principle: when the handle 306 is rotated, the torque is transmitted through the transmission shaft 305 and the right-angle steering gear 304, and is driven to rotate the lead screw 303. The lead screw 303 converts the rotary motion into linear motion through the thread engagement with the fixed threaded sleeve 302, thereby driving the dirt cabin to stably ascend and descend along the guide rod 301. The guide rod ensures the direction, and the self-locking characteristic of the lead screw mechanism ensures that the cabin can be safely parked at any position.

[0052] As shown in Figure 3 and Figure 7 , the spraying execution part of the moisturizing and disinfecting unit is two groups of symmetrical spray assemblies arranged on the inner side wall of the dirt treatment cabin 300. The structural details are shown in Figure 3 , the unit also includes a liquid storage container 407 and a liquid delivery pump 406 arranged on the mobile chassis 100. Each set of spray assembly includes a support 400 fixed on the cabin wall, a swing rod 402 hinged to the support 400 through a shaft rod 401, and a spray pipe 404 and a spray head 405 installed on one end of the swing rod 402. The inlet of the liquid delivery pump 406 is connected to the liquid storage container 407 through a pipeline, and the outlet is connected to the spray pipe 404 through a pipeline.

[0053] Working principle: the liquid delivery pump 406 pumps the liquid in the liquid storage container 407 and delivers it to the spray assembly through the pipeline. The symmetrical arrangement of the spray assembly ensures uniform spraying. The hinged design of the swing rod 402 and the support 400 provides a swing degree of freedom, which provides a structural basis for automatic avoidance.

[0054] As shown in Figure 7 , in the above-mentioned spray assembly, an elastic reset member 403 is arranged between the swing rod 402 and the support 400, and the two ends are respectively connected to the swing rod 402 and the support 400. When the instrument tray 206 is controlled to descend into the dirt treatment cabin 300, the bottom of the electronic scale 204 will contact and press one end of the swing rod 402, forcing the swing rod 402 to rotate against the elastic force of the elastic reset member 403, thereby driving the spray pipe 404 and the spray head 405 to swing upward to the spraying position. When the instrument tray 206 is raised and leaves, the swing rod 402 is automatically reset under the restoring force of the elastic reset member 403, so that the spray pipe 404 and the spray head 405 return to the position beside the instrument tray 206.

[0055] As shown in Figure 4 , the treatment vehicle also includes a hatch closure unit, which includes a second telescopic drive 500 and a baffle 501. The second telescopic drive 500 is fixedly installed on the side of the top opening of the vehicle body 101, and the telescopic end is connected with the baffle 501.

[0056] Working principle: when the device is idle or spraying, the control module can instruct the second telescopic drive 500 to act, drive the baffle 501 to move to close the opening at the top of the vehicle body, effectively isolate external pollutants, and protect the clean state of the internal instrument tray and sensor.

[0057] As shown in Figure 5 The dynamic weighing module integrated in the electronic scale 204 is configured to have intelligent capture capability, and its working mode is to continuously monitor the weight change in real time, and automatically trigger the recording of the stable weight value when the weight reading is detected to be stable. The module ensures the reliability of the weight data. It continuously monitors and uses internal algorithms to determine when the weight value reaches a stable state. For example, when the weight fluctuation is small for a continuous period of time, only at the stable moment is the key weight node data automatically recorded, thereby filtering the instantaneous fluctuation error caused by human operation.

[0058] The core function of the data processing and control module is to execute a complete set of intelligent instrument checking algorithm. The flow and decision of the algorithm are as follows: first, in the preoperative preparation stage, control the lifting unit to lift the instrument tray 206, record the first weight value W1, and obtain the first instrument list through the industrial camera 600. After checking, control the lifting unit to reset, and control it to lift during surgery. In the intraoperative stage, continuously monitor and record the second weight value W2 after the instrument is taken. In the postoperative return stage, record the third weight value W3 after the instrument is returned, and obtain the second instrument list again. In the checking and output stage, parallel weight closed-loop comparison and visual list comparison are carried out, and according to the double comparison results, the checking conclusion or alarm is output through the man-machine interaction unit. The weight closed-loop comparison refers to judging whether the difference between W3 and W2 is not greater than the preset threshold δ. The specific rules output by the system are as follows: if the weight closed-loop comparison passes and the two instrument lists are consistent, it is determined that the checking is successful; if the weight closed-loop comparison does not pass but the two instrument lists are consistent, the first type of alarm is triggered; if the two instrument lists are inconsistent, regardless of the weight closed-loop comparison result, the second type of alarm is triggered. The first type of alarm refers to the consistency of the visual list under the condition of weight abnormality, and the system determines that there is a high risk of leaving non-instrument items such as dressings. At this time, the core principle of the system is interruption, assistance and prompt. The system will start the sound and light alarm 103 to warn, and automatically lock and suspend the subsequent instrument tray descent and other automatic processes to prevent the problem from being covered up. The data processing and control module will immediately call the correlation analysis subroutine to give specific weight deviation analysis and suspected item prompt on the display screen 102, such as a weight difference of about 12 grams and a suspected piece of gauze, so as to accurately locate the problem and efficiently guide the medical staff to conduct targeted review. At the same time, the system starts the network collaborative response mechanism. The communication module built in the treatment trolley will immediately generate a standardized first type of alarm data packet, which contains key data such as event type, device number, location operating room, associated surgical information, specific weight difference and system speculated left-over type, and is transmitted to the nurse station central monitoring system through the hospital intranet encryption. The nurse station screen will receive the warning identifier of the device, reminding the circulating head nurse or on-duty nurse to pay attention to the abnormal state of the operating room, realizing cross-regional supervision and reminding.The second type of alarm, i.e., visual inventory inconsistency, is the highest level risk of missing surgical instrument body, and the system immediately upgrades the response principle to forced termination, locking and clear indication. The system starts the highest priority sound and light alarm, and forcibly interrupts all automated operations, and places the treatment cart in a safe locking state. On the display screen 102, the system clearly highlights the missing instrument item, and clearly requires immediate manual counting. The core safety logic of this design is that the missing instrument is regarded as an insurmountable red line. The system no longer provides any automation convenience, and must be completely solved by medical staff and manually confirmed before the system is unlocked and restored to use. In this emergency situation, the network cooperation mechanism is activated to the highest priority. The treatment cart not only sends an alarm to the nurses' station, but also synchronously broadcasts the alarm information to the broadcasting system of the operating room, the workstation of the surgeon, and the mobile terminal of the relevant management personnel according to the configuration of the hospital system. The alarm data packet is forcibly written into the electronic operation record of the current patient, forming an indelible key safety event marker. The core logic of this design is that the missing instrument is regarded as an emergency event that must mobilize the process resources of the entire hospital to respond. Through the network, instantaneous, multi-point and traceable forced early warning is realized to ensure that relevant personnel intervene at the first time. The treatment cart can only be unlocked by authorized personnel after medical staff completely solve the problem and complete manual confirmation on the system. At the same time, the system sends an alarm cancellation signal to the network, completing the electronic closed loop of the entire safety event.

[0059] Working principle: This algorithm realizes full-process automatic checking and risk classification. It divides the surgical process into preoperative, intraoperative and postoperative stages, and systematically collects weight and visual data. The core innovation is the introduction of weight closed-loop comparison logic, i.e., checking whether the total weight W3 returned and the remaining weight W2 after use match, forming a closed-loop check of physical quantity conservation. Combined with visual inventory comparison, a double evidence chain is formed. The system makes judgments according to the preset clear rules, can distinguish between risks of different natures such as missing instrument body and leaving of dressing items, and triggers corresponding alarms.

[0060] When the above-mentioned first type of alarm is triggered, the data processing and control module is further configured to perform further analysis, and according to the weight difference ΔW and the pre-stored single instrument weight database, to perform correlation matching calculation, so as to infer the type or combination of the items that may cause the weight deviation, and output a prompt.

[0061] Working principle: When a weight abnormality alarm occurs, the system uses the weight difference ΔW as the target value to perform matching calculation in the instrument and dressing standard weight database, to find the most possible combination of items, and generates specific prompts to provide key clues for medical staff to quickly locate the problem.
