Description

Technical Field

[0001] This disclosure relates to the field of medical device technology, and in particular to an intelligent identification device for abnormal clinical puncture of a puncture needle, its usage method, and an electronic device. Background Technology

[0002] Clinically, patients have many puncture needles, such as indwelling needles, deep vein catheters, PICC lines, etc. When using them, it is necessary to apply a dressing to fix the puncture needle in place to prevent the needle from falling off.

[0003] Abnormalities in the puncture needle need to be observed, such as whether the needle has come out, how much it has come out, the condition of the skin at the puncture site, redness, swelling, exudation, etc. These are usually only noticed by the patient or their family members and can be called by the nurse in time. However, sometimes patients may overlook these abnormalities in the puncture, which can lead to a greater risk of puncture complications.

[0004] Therefore, currently, there is no way to intelligently monitor abnormal clinical use of puncture needles, such as needle dislodgement or effusion at the puncture site, and there is no way to automatically send alarms to nurses in a timely manner for such puncture abnormalities. Summary of the Invention

[0005] To address the aforementioned issues, this application proposes an intelligent identification device for abnormal clinical puncture needles, its usage method, and an electronic device.

[0006] This application proposes, in one aspect, an intelligent identification device for abnormal clinical puncture of a puncture needle, comprising:

[0007] The dressing is composed of an adhesive layer 1, a core layer 3, an inner surface layer 9, and a protective film.

[0008] The core layer 3 is provided with a support 2, a stop bar 5, a tension spring 4 and a contact switch 8, wherein one end of the stop bar 5 is hinged to the support 2 and the other end extends out of the core layer 3; the two ends of the tension spring 4 are respectively connected to the support 2 and the stop bar 5;

[0009] A humidity sensor 10 is provided on the inner surface layer 9;

[0010] Controller 7, located within the dressing, includes:

[0011] The MCU is used to monitor the signals fed back by the contact switch 8 and / or the humidity sensor 10, and to determine whether to issue an abnormal alarm signal.

[0012] The data cable is used for communication between the MCU and the nursing backend to send the abnormal alarm signal to the nursing backend.

[0013] Power supply, used for supplying power;

[0014] The contact switch 8, the humidity sensor 10, the data line, and the power supply are all electrically connected to the MCU.

[0015] As an optional embodiment of this application, the housing containing the controller 7 is optionally located on the inner surface layer 9 and its top extends through the core layer 3.

[0016] As an optional embodiment of this application, the upper surface of the core layer 3 may be provided with a stepped surface or be a hollow frame, and the bottom may be open;

[0017] The support 2, the stop bar 5, the tension spring 4, and the contact switch 8 are all located on the stepped surface or inside the hollow frame. The lower end of the stop bar 5 extends out of the opening, and the contact switch 8 at the opening makes elastic contact.

[0018] As an optional embodiment of this application, the lower end of the stop bar 5 is provided with a lever 6 for moving the stop bar 5 away from the contact switch 8 to facilitate piercing;

[0019] Before puncture, use the lever 6 to move the stop bar 5 away from the contact switch 8;

[0020] The puncture needle 11 is inserted into the dressing located between the stop bar 5 and the contact switch 8 at a certain puncture angle, keeping the needle tip through the dressing and exposed at the puncture site;

[0021] When the stop bar 5 is released, the puncture needle 11 is blocked by the stop bar 5 under the pull of the tension spring 4;

[0022] Tear off the protective film at the bottom of the dressing, move the dressing and align the exposed puncture site with the puncture point, and continue puncturing until the adhesive layer contacts and fixes to the body surface;

[0023] If the puncture needle 11 is dislodged, the stop bar 5 returns to its original position and contacts the contact switch 8 at the opening. When the contact switch 8 contacts, it sends a contact signal back to the MCU.

[0024] When the MCU receives the contact signal, it issues a first abnormal alarm signal and sends it to the nursing backend via a data cable.

[0025] As an optional implementation of this application, the humidity sensor 10 may be a plurality of flexible humidity sensors arranged in a matrix, each of the flexible humidity sensors being electrically connected to the MCU and feeding back a humidity value signal to the MCU.

[0026] When the MCU receives the humidity value signals fed back by each of the flexible humidity sensors:

[0027] If at least one of the humidity value signals corresponds to a humidity value that exceeds a preset value, a second abnormal alarm signal is issued and sent to the nursing backend via a data cable;

[0028] If the average humidity value corresponding to each of the humidity value signals exceeds the preset value, a second abnormal alarm signal is issued and sent to the nursing backend via a data cable.

[0029] In another aspect, this application proposes a method for using a smart device for identifying abnormal clinical puncture needles, comprising the following steps:

[0030] Connect the data cable attached to the dressing to the nursing back office;

[0031] Determine the puncture angle and depth of the puncture needle 11 on the dressing;

[0032] Use the lever 6 to move the stop bar 5 away from the contact switch 8;

[0033] Insert the puncture needle 11 into the dressing located between the stop bar 5 and the contact switch 8 at the puncture angle, keeping the needle tip through the dressing and exposing the puncture site corresponding to the depth;

[0034] When the stop bar 5 is released, the puncture needle 11 is blocked by the stop bar 5 under the pull of the tension spring 4;

[0035] Tear off the protective film at the bottom of the dressing, move the dressing and align the exposed puncture site with the puncture point, and continue puncturing until the adhesive layer contacts and fixes to the body surface;

[0036] The MCU determines whether to issue an abnormal alarm signal:

[0037] If the puncture needle 11 is dislodged, the stop bar 5 returns to its original position and contacts the contact switch 8 at the opening, and the contact switch 8 feeds back a contact signal to the MCU; when the MCU receives the contact signal, it issues a first abnormal alarm signal and sends it to the nursing backend via the data line.

[0038] When the MCU receives humidity value signals from each of the flexible humidity sensors:

[0039] If at least one of the humidity value signals corresponds to a humidity value that exceeds a preset value, a second abnormal alarm signal is issued and sent to the nursing backend via a data cable;

[0040] If the average humidity value corresponding to each of the humidity value signals exceeds the preset value, a second abnormal alarm signal is issued and sent to the nursing backend via a data cable.

[0041] In another aspect, this application also proposes an electronic device comprising:

[0042] processor;

[0043] Memory used to store processor-executable instructions;

[0044] The processor is configured to execute the executable instructions to implement the MCU execution program in the usage method.

[0045] Technical effects of the present invention:

[0046] This application utilizes a puncture structure within a dressing, incorporating sensors and an MCU (Microcontroller Unit). This allows for timely notification to the MCU chip of abnormal puncture conditions such as needle dislodgement or bleeding. The MCU chip is immediately aware of any needle dislodgement and communicates with the nursing backend via a data cable, instructing the nurse to proceed to the appropriate patient for clinical care. Upon receiving a contact signal from a contact switch or a humidity value signal from a humidity sensor, the MCU chip can determine, based on its own judgment method, whether to send an abnormal alarm signal to the nursing backend, notifying the nurse to attend to the current patient. Therefore, it enables real-time monitoring of abnormal puncture situations, timely notification to nurses, and prevention of significant puncture complications caused by patient and family negligence.

[0055] Various exemplary embodiments, features, and aspects of this disclosure will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0056] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0057] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0058] In this solution, the structure and thickness of the dressing are not limited, nor are the corresponding materials.

[0059] The inner core layer 3 needs to be made of foam or silicone to provide some support. The other layers are all made of soft materials.

[0060] The top layer is adhesive layer 1, and its dimensions on all sides exceed those of the other internal layers to facilitate adhesion after contact with the body surface.

[0061] The dressing can be applied to the puncture site first, and then a puncture needle can be used to puncture the puncture point on the body surface through the dressing.

[0062] Alternatively, the puncture needle can be inserted into the dressing at the required angle and depth, and then the dressing can be applied to the body surface, thus completing the puncture simultaneously.

[0063] The order of the above steps is not limited and can be completed by the nurse according to her habits, with the first option being preferred.

[0064] The following section will describe the application structure and principle of this solution.

[0065] Example 1

[0066] like Figure 1-5 As shown, this application proposes, in one aspect, an intelligent identification device for abnormal clinical puncture of a puncture needle, comprising:

[0067] The dressing is composed of an adhesive layer 1, a core layer 3, an inner surface layer 9, and a protective film.

[0068] The core layer 3 is provided with a support 2, a stop bar 5, a tension spring 4 and a contact switch 8, wherein one end of the stop bar 5 is hinged to the support 2 and the other end extends out of the core layer 3; the two ends of the tension spring 4 are respectively connected to the support 2 and the stop bar 5;

[0069] A humidity sensor 10 is provided on the inner surface layer 9;

[0070] Controller 7, located within the dressing, includes:

[0071] The MCU is used to monitor the signals fed back by the contact switch 8 and / or the humidity sensor 10, and to determine whether to issue an abnormal alarm signal.

[0072] The data cable is used for communication between the MCU and the nursing backend to send the abnormal alarm signal to the nursing backend.

[0073] Power supply, used for supplying power;

[0074] The contact switch 8, the humidity sensor 10, the data line, and the power supply are all electrically connected to the MCU.

[0075] like Figure 2 As shown, this solution uses a patch structure for needle puncture and performs intelligent identification of abnormal punctures in clinical practice.

[0076] The dressing itself has a soft structure, specifically composed of four layers. When the first adhesive layer is peeled off, the core layer is exposed. This core layer has a certain thickness and its upper surface has a stepped surface or a hollow frame structure. Inside the core layer, there is a stop bar structure that can block the puncture needle. After the puncture needle is dislodged, the stop bar returns to the right under the traction of the tension spring and contacts the contact switch. When the contact switch is contacted by the stop bar, it generates a contact signal and sends feedback to the controller inside the dressing. At this time, the MCU chip is notified. The MCU chip is aware of the puncture needle dislodging and communicates with the nursing backend (connected to the nurse station host via the data cable for operation by the nurse administrator) via the data cable, thereby instructing the nurse to go to the corresponding patient for clinical care.

[0077] like Figure 3 As shown, after peeling back the core layer, the inner surface layer is exposed. On the upper surface of this inner surface layer, several flexible humidity sensors are arranged in a matrix. Each flexible humidity sensor is a thin, sheet-like sensor patch structure distributed on the inner surface layer. Upon contact with the patient's skin, it can monitor the humidity of the skin surface. For example, if bleeding occurs at the puncture site, the flexible sensor patch can monitor the humidity of the inner surface layer and send a humidity detection signal to the MCU (Microcontroller Unit). The MCU then determines whether bleeding has occurred at the puncture site.

[0078] like Figure 4 As shown, during puncture, the stop bar 5 is opened, and the puncture needle is passed through the dressing according to the preset puncture angle and depth. After the puncture needle passes through, the stop bar 5 is released, and the puncture needle blocks the stop bar 5. At this time, under the pull of the tension spring 4, if the puncture needle comes out, the stop bar 5 will return to the rightmost position and contact the internal contact switch 8. The contact switch 8 will sense a contact signal and feed it back to the MCU. After receiving the contact signal, the MCU will know that the puncture needle has come out and will communicate with the nursing backend to inform the backend nurse that the patient has experienced an abnormal situation of puncture needle dislodgement.

[0079] like Figure 5 As shown, when the MCU chip receives the contact signal from the contact switch or the humidity value signal from the humidity sensor, it can determine whether to send an abnormal alarm signal to the nursing backend based on its own judgment method, and notify the nurse to go to the current clinical patient for care.

[0080] Therefore, it can monitor abnormal puncture situations in real time and notify nurses in a timely manner.

[0081] like Figure 1 As shown, before puncture, the lever 6 is used to move the stop bar 5 away from the contact switch 8; the puncture needle 11 is inserted into the dressing located between the stop bar 5 and the contact switch 8 at a certain puncture angle, keeping the needle tip through the dressing and exposed at the puncture site; the stop bar 5 is released, and under the pull of the tension spring 4, the puncture needle 11 is blocked by the stop bar 5.

[0082] Because the overall dressing has a soft structure and its thickness can be controlled between 3 and 10 mm, rather than being a rigid material, the puncture needle can be inserted first before applying it to the patient's skin. Once the dressing is applied, the puncture needle is simultaneously inserted into the corresponding puncture site (at the pre-set puncture angle and depth).

[0083] Each patient's puncture needle can communicate with the nursing backend via a data cable. This data cable can also be replaced with wireless communication, such as Bluetooth or a wireless WiFi module.

[0084] As an optional embodiment of this application, the housing containing the controller 7 is optionally located on the inner surface layer 9 and its top extends through the core layer 3.

[0085] The controller is a small cube-shaped structure, housed in a square casing about the size of a fingernail (a thin plate box containing a circuit board and MCU). Its interior is sealed with a sealing material, encapsulating the MCU chip, power supply, and other components. The casing has openings for data cables to pass through.

[0086] In practice, the controller is housed in a corner of the applicator. To prevent it from being exposed, it is placed between the outer adhesive layer and the inner surface layer, which can be made of non-woven fabric or breathable material.

[0087] The small square housing containing the controller can be fixed inside the patch using adhesive or other methods.

[0088] As an optional embodiment of this application, the upper surface of the core layer 3 may be provided with a stepped surface or be a hollow frame, and the bottom may be open;

[0089] The support 2, the stop bar 5, the tension spring 4, and the contact switch 8 are all located on the stepped surface or inside the hollow frame. The lower end of the stop bar 5 extends out of the opening, and the contact switch 8 at the opening makes elastic contact.

[0090] like Figure 2 and 3 As shown, the upper surface of the core layer 3 is a stepped surface, but its bottom is open, and a contact switch 8 is fixedly glued to the bottom opening. A support 2 (a rigid strip glued on) is provided on the inner side of the top frame of the stepped surface. A stop bar held by a tension spring 4 is fixed on the support 2 (if the stop bar 5 is made of elastic material, the tension spring 4 is not required). In use, the stop bar 5 is moved to the left, away from the contact switch, using the lever 6, and then the puncture needle is inserted into the patch. The stop bar is then released, and the puncture needle blocks the stop bar 5.

[0091] When blocked, the stop bar 5 separates from the contact switch 8. If the puncture needle comes out, the stop bar 5 returns to its original state and contacts the contact switch 8.

[0092] This embodiment does not consider the depressions or collapses of the adhesive layer on the application surface caused by stepped surfaces or hollow frames.

[0093] like Figure 5 As shown, as an optional embodiment of this application, the lower end of the stop bar 5 is provided with a lever 6, which is used to push the stop bar 5 away from the contact switch 8 to facilitate piercing;

[0094] Before puncture, use the lever 6 to move the stop bar 5 away from the contact switch 8;

[0095] The puncture needle 11 is inserted into the dressing located between the stop bar 5 and the contact switch 8 at a certain puncture angle, keeping the needle tip through the dressing and exposed at the puncture site;

[0096] When the stop bar 5 is released, the puncture needle 11 is blocked by the stop bar 5 under the pull of the tension spring 4;

[0097] Tear off the protective film at the bottom of the dressing, move the dressing and align the exposed puncture site with the puncture point, and continue puncturing until the adhesive layer contacts and fixes to the body surface;

[0098] If the puncture needle 11 is dislodged, the stop bar 5 returns to its original position and contacts the contact switch 8 at the opening. When the contact switch 8 contacts, it sends a contact signal back to the MCU.

[0099] When the MCU receives the contact signal, it issues a first abnormal alarm signal and sends it to the nursing backend via a data cable.

[0100] As an optional implementation of this application, the humidity sensor 10 may be a plurality of flexible humidity sensors arranged in a matrix, each of the flexible humidity sensors being electrically connected to the MCU and feeding back a humidity value signal to the MCU.

[0101] When the MCU receives the humidity value signals fed back by each of the flexible humidity sensors:

[0102] If at least one of the humidity value signals corresponds to a humidity value that exceeds a preset value, a second abnormal alarm signal is issued and sent to the nursing backend via a data cable;

[0103] If the average humidity value corresponding to each of the humidity value signals exceeds the preset value, a second abnormal alarm signal is issued and sent to the nursing backend via a data cable.

[0104] If the MCU chip receives a contact signal, it indicates that the puncture needle has dislodged, and the back-end nurse is notified. If humidity sensing is used for monitoring, if a flexible humidity sensor patch detects a humidity value exceeding a preset value, it is determined that there may be puncture bleeding on the patient's skin, and an alarm is triggered. If the value does not exceed a preset value, the MCU calculates the average of the humidity signals detected by each humidity sensor and further compares them with threshold values ​​to determine whether there is any possible abnormal puncture bleeding.
