Technical Field

[0001] The invention belongs to the field of hospital auxiliary equipment, and in particular relates to a remote sensing counting type surgical gauze collector and a gauze collecting method. Background Art

[0002] With the continuous improvement of medical technology, more and more diseases can be treated by surgery. Surgery is a rigorous treatment process. In order to ensure the smooth progress of the operation, there are strict work requirements for the inventory of surgical instruments and dressings. Among them, the inventory of gauze is the top priority. As long as the operation uses gauze, no matter the size of the operation or the length of time, the gauze must be counted to prevent the gauze from being left in the patient's body for various reasons, causing serious medical accidents.

[0003] The current gauze inventory work generally requires the hand-washing nurse and the circulating nurse to complete it together. The process is relatively complicated and requires close cooperation and long-term concentration and carefulness, which places high demands on medical staff. However, because it is directly related to the health of patients and is a very important job, with the development of science and technology, more and more new technologies are applied to this field. For example, the Chinese patent with announcement number CN212580685U discloses a medical waste intelligent management system dedicated to the operating room. The system can automatically count the gauze used in the operation, but only the gauze after use is listed, and the entire inventory process is not included. There are still many inconveniences in use, and it is necessary to refer to the existing management system for multi-person operation to ensure the inventory effect. Summary of the invention

The inner hole of the bearing cooperates with the short shaft, and a baffle is provided on the outside of the convex ring perpendicular to the center of the circle, and the baffle faces the opening side of the upper box. The baffle cooperates with the limit baffle so that the opening of the upper box and the opening of the lower box are not located on the same side.

[0013] The gauze recovery barrel comprises a barrel body, and an inclined support plate, a plate clamping mechanism, a motor, a rotating shaft, and a C-shaped driving ring are arranged on the front end surface of the barrel body. The motor is installed on the side wall of the barrel body. The plate clamping mechanism comprises a plurality of mesh plates, and mesh plates extend from the lower ends of both sides of the mesh plates to form mounting legs. Rings are arranged at the ends of the mounting legs, and the rings are sleeved on the rotating shaft.

It can automatically register the gauze needed for the operation and automatically count the gauze after use, so as to prevent medical accidents caused by missing gauze. At the same time, the registration and recovery of gauze are arranged in layers, which is convenient for two people to operate at the same time. Moreover, the gauze recovery bucket has a quantitative storage function. Once the system responds that the number of gauze does not correspond, it is convenient for medical personnel to quickly manually check the number of gauze after use.

[0016] A surgical gauze collection method comprises the following steps: 1. gauze with an RFID tag is placed in an upper box, and a control system registers the placed gauze through a first RFID reader; 2. in an initial state, the bottom of the buffer box is open, and when a user throws the used gauze into a gauze recovery bucket in a lower box, a second RFID reader records the used gauze information, and the gauze directly falls into a storage space formed by a mesh plate of a plate clamp mechanism in the lower box, and a control system controls an electric door closer of the buffer box to pull a moving plate upwards to close the bottom of the buffer box; 3. The second RFID reader continues to read the information of the used gauze put in, and when the read information is consistent with the classification information of the last used gauze, the control system controls the electric door closer to Open the movable plate downward to make it fall into the plate clamping mechanism below, and then close the bottom plate. When the read information is inconsistent with the classification information of the gauze after the previous use, the control system first drives the C-type driving circle to replace the storage space formed by the mesh plate of the plate clamping mechanism, and then drives the electric door closer to open the movable plate downward to release the gauze on it, and then close the bottom plate; 4. Repeat step 3 until the last mesh plate of the plate clamping mechanism is overlapped and closed with the front baffle, and the shelf mechanism is taken out from the C-type driving circle; 5. The control system compares the registered gauze with the number of gauze registered after use, and inputs it into the display and printer for data output. At the same time, the number and type information of the used gauze stored between every two mesh plates are output to the display and printer for data output.

[0017] The surgical gauze collection method of the present invention can automatically count the gauze used in the operation, solve the complexity of manually cleaning the gauze, and while counting the gauze, the gauze can be reasonably stored and classified. Once the counted number of gauze does not match, it can assist medical personnel to quickly count, thereby reducing the problem of delaying the normal operation process due to unclear gauze count.

[0026] In order to more clearly illustrate the technical solution of the present invention, the following embodiments are used for specific description.

[0027] Example 1 like Figure 1 , 2 As shown, a remote sensing counting surgical gauze collector is used to count gauze with RFID chips, including an upper box 1, a lower box 2, a control system composed of an MCU microprocessor, a first RFID reader 3, a second RFID reader 4, a display 5, and a label printer 6.

[0028] The upper box body 1 and the lower box body 2 are arranged up and down and fixedly connected. The height of the lower box body is higher than that of the upper box body. Both the upper box body 1 and the lower box body 2 are hollow boxes with openings arranged on the side walls. The opening directions of the upper and lower boxes are arranged front to back, which is convenient for two staff members to operate at the same time; a slot is arranged on the bottom plate of the upper box body 1, and a first RFID reader 3 is installed in the slot, which is used to record and register the surgical gauze to be used in the cavity of the upper box body; an MCU microprocessor, a display 5, and a label printer 6 are installed on the top plate of the upper box body 1; the display 5 and the label printer 6 are connected to the MCU microprocessor circuit for displaying data and printing relevant data labels; a slot is arranged on the side wall on the opposite side of the opening of the lower box body 2, and a second RFID reader 4 is arranged in the slot, which is used to record the used gauze thrown into the lower box body; the first RFID reader 3 and the second RFID reader 4 are connected to the MCU microprocessor circuit for obtaining the information of the first and second RFID readers and checking whether the quantity of gauze used before and after is consistent.

[0029] In order to optimize the user experience, movable handrails 11 are symmetrically installed on both sides of the upper box body, and casters 12 with brakes are installed at the four corners of the bottom of the lower box body to facilitate the movement of the device. Slide rails can also be set on the two side walls of the upper box body 1, and pull-out plates can be installed to facilitate the storage and retrieval of gauze; it also includes a gauze recovery bucket 21, which is placed inside the lower box body 2. At this time, the installation position of the second RFID reader corresponds to the upper part of the gauze recovery bucket 21 to ensure stable reading; further optimized, an inclined surface 22 is provided on the upper part of the inner cavity of the lower box body, one end of the inclined surface 22 is connected to the upper end of the opening of the lower box body, and the other end is connected to the inner side of the gauze recovery bucket therein. When the user puts used gauze into the gauze recovery bucket 21, it can assist the gauze to enter the bucket smoothly without being thrown into the space of the lower box body.

[0030] During use, the nurse puts the gauze needed for the operation into the upper box, and the first RFID reader 3 reads and records the gauze information. During the operation, the user puts the used gauze into the gauze recovery bucket. At this time, the second RFID reader 4 records the used gauze and compares the quantity before and after use through the control system to see if it is consistent. Example 2

[0031] Example 2 further optimizes the technical solution of the present invention. On the basis of Example 1, Figure 3 As shown, in this embodiment, a mounting groove 71 is provided on the top of the lower box body 2, and a short shaft 72 is installed in the center of the mounting groove. Limit baffles 73 are symmetrically provided on the left and right sides of the short shaft 72, and there is a gap between the limit baffle 73 and the rotating shaft 72. A convex ring 81 is provided on the bottom plate of the upper box body 1, and a bearing is installed in the convex ring 81. The inner hole of the bearing cooperates with the short shaft. After installation, the convex ring is just located in the gap between the limit baffle 73 and the rotating shaft 72, and a baffle 82 is provided on the outside of the convex ring perpendicular to the center of the circle, and the baffle faces the opening side of the upper box body. The baffle cooperates with the limit baffle so that the upper box body opening and the lower box body opening are located on the same side. After adopting the above arrangement, the upper box body can realize a limited angle rotation on the lower box body to ensure that the upper box body opening and the lower box body opening are not on the same side. In this way, during use, nurses and doctors can flexibly adjust the opening position of the upper and lower boxes according to their own positions, which is convenient for taking and putting in gauze, and the operation is more flexible. Example 3

[0032] In Example 1, a common gauze recovery bucket was used, such as Figure 4-7 As shown, in order to further optimize the performance of the device in this embodiment, the gauze recovery barrel is further improved. The gauze recovery barrel 21 includes a barrel body, and the front end surface of the barrel body is provided with an inclined support plate 23, a plate clamping mechanism, a motor 26, a rotating shaft 24, a C-shaped drive ring 25, and a power supply. The power supply and the motor 26 are installed on one side wall of the barrel body, and the power supply is used to power the motor. The plate clamping mechanism comprises a plurality of mesh plates 27, the mesh plates extending from the lower ends of both sides of the mesh plates form mounting legs, the mounting legs are provided with collars 271 at the ends, the collars 271 are sleeved on the rotating shaft 24, the width of the plurality of mesh plates is gradually reduced, so as to ensure that the collars on the mounting legs are arranged in sequence on the rotating shaft and do not overlap, and a driving buckle 272 is provided at the upper end of one side of the mesh plate 27, the driving buckle 272 buckle is perpendicular to the side of the mesh plate and is located in the same plane as the mesh plate, and every two adjacent mesh plates can form a storage space, and the plate clamping mechanism thus forms a plurality of storage spaces, which can realize quantitative storage, and is convenient for manual rapid review at the first time after an accident occurs, and at the same time, the mesh plates can squeeze the gauze to a certain extent when they are closed, so as to squeeze the blood into the bottom of the barrel; it should be noted that the opening and closing size of the two mesh plates can be flexibly set, and when it is set to a space with a smaller opening and closing distance, in order to ensure that the gauze falls into the storage space, a shielding plate can be provided at the upper end of the rear mesh plate according to the opening and closing situation of the mesh plate, so as to ensure that the gauze can only be thrown between the two unfolded mesh plates, The C-shaped driving ring 25 includes a C-shaped ring, a sleeve, and a plurality of connecting rods. The sleeve is fixed at the center of the C-shaped ring by the plurality of connecting rods. The sleeve is connected to the output shaft of the motor 26. Rubber positioning rings 251 are fixedly connected to the C-shaped ring at equal intervals. The rubber positioning rings 251 cooperate with the driving buckle 272. A groove 231 is provided on the inclined support plate 23. The groove matches the shape of the largest mesh plate. A long opening 232 is provided on one side of the groove for the passage of the C-shaped driving ring. The controller of the motor 26 is connected to the MCU microprocessor circuit. The MCU microprocessor drives the C-shaped driving ring to rotate step by step according to the count feedback from the second RFID reader.

[0033] At the beginning of use, each mesh plate is fixed corresponding to a positioning ring 251, and the motor is started to initialize the position. The first mesh plate is positioned on the inclined support plate, and the first mesh plate and the second mesh plate form a storage space. When the medical staff puts in gauze, the second RFID reader starts counting. The count is set to 5 in the present invention. After 5 used gauzes are put in, the motor starts to drive the C-shaped drive circle to move and rotates a step length, that is, the distance between the two positioning rings, so that the first and second mesh plates are superimposed, and the second and third mesh plates form a new storage space. The rubber positioning ring 251 and the drive buckle 272 only need to provide a slight friction force to drive the mesh plate to move, so that the C-shaped drive circle can pass through the drive buckle of the superimposed mesh plate when rotating. The work can be repeated until the last mesh plate is superimposed, and the plate clamping mechanism can be taken out from the gap of the C-shaped drive circle.

[0034] After adopting the gauze recovery barrel of the above structure, the used gauze can be quantitatively separated and stored by counting. Once the quantity of gauze before and after use does not match, the staff can quickly sort and review to determine whether there is a misreading, missed reading, or the gauze chip accidentally falls off and cannot be counted. Example 4

[0035] like Figure 8 As shown, the gauze recovery barrel is further optimized, and also includes a buffer box 29, which is integrally arranged on the upper part of the gauze recovery barrel. The bottom surface of the buffer box 29 is composed of an inclined plate 291, a movable plate 292, and an electric door closer 293. The inclined plate 291 is obliquely fixedly connected to the lower part of the inner wall of the buffer box, and one end of the movable plate 292 is hinged to the lower part of the inner wall of the buffer box. One end of the electric door closer 293 is fixedly connected to the movable plate 292, and the other end is fixedly connected to the buffer box wall 29. When the inclined plate and the movable plate are connected and closed, the bottom of the cone is flush with the buffer box body, and the electric door closer is connected to the control system circuit. Among them, the cone bottom of the inclined plate and the movable plate is set to facilitate the use of gauze to fall into the plate clamp mechanism below after the movable plate is opened. The electric door closer is a prior art detailed structure and is not repeated.

[0036] By setting up a buffer box, gauze can be classified and stored. Different types of gauze may be used in some surgeries, such as hemostatic long gauze and dressing gauze. This can further rationalize the storage and output information to medical staff through the control system. Once a problem with the number of gauze occurs, medical staff can quickly count it and first eliminate counting errors caused by equipment failures such as misreading, missed reading or accidental chip falling.
