Abstract
Description
Technical Field
[0001] This utility model belongs to the field of recording pen technology, specifically relating to a doctor-patient conversation recording pen. Background Technology
[0002] Preoperative consultation refers to a face-to-face exchange between a doctor and a patient before surgery. Its purpose is to ensure the patient has a full understanding of the surgical procedure and postoperative recovery, and to obtain informed consent. Preoperative consultation is a crucial part of hospital surgical safety management, significantly contributing to improved surgical safety and patient satisfaction. Although seemingly simple, it embodies profound medical, ethical, and communication skills. It not only tests the surgeon's medical skills and ethics but is also a key step in establishing a good doctor-patient relationship and reducing medical disputes. Therefore, audio recording devices are used to capture the content of these conversations.
[0003] Most current voice recorders are one-piece structures that cannot be disassembled and require replacement as a whole. At the same time, existing voice recorders are inconvenient to carry and cannot hide the card reader. The exposed card reader can easily cause patients to resist and affect the conversation. Furthermore, the card reader cannot be held in place and can easily become loose, affecting the storage of the recorded information. Therefore, we propose a new type of voice recorder for doctor-patient conversations. Utility Model Content
[0004] The purpose of this utility model is to provide a doctor-patient conversation recording pen to solve the problems mentioned in the background art. Most of the current recording pens are of a single-piece structure, which cannot be disassembled and requires replacement as a whole. At the same time, existing recording pens are inconvenient to carry, and the card reader cannot be hidden. The exposed card reader is likely to cause patient resistance and affect the conversation. Furthermore, the card reader cannot be pressed and fixed, which can easily cause the card reader to loosen and affect the storage of the recorded information.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-2 This utility model provides a technical solution: a doctor-patient conversation recording pen, wherein a detachable pen holder 2 is provided on one side of the pen barrel 3, and a detachable pen cap structure 1 is provided on one side of the pen holder 2;
[0027] A microphone 203 is also provided on one side of the pen holder 2. The microphone 203 is connected to the built-in PCB circuit board 204. The PCB circuit board 204 is fixed in the circuit board bracket 208 by screws. The circuit board bracket 208 is fixed in the inner sleeve 205. The inner sleeve 205 is set in the pen holder 2. The PCB circuit board 204 is also connected to the data interface 207, which is located on one side of the pen holder 2. Specifically, the PCB circuit board 204 consists of a voice IC, a microcomputer, a microphone 203 microphone head, and a resistor, which can store and transmit recording files. The pen cap structure 1 includes an end cover 101. The end cover 101 is detachably connected to the pen holder 2 and is used to cover and fix the card reader 106. A control switch 201 is also provided on the outer surface of the pen holder 2. The control switch 201 controls the operation of the PCB circuit board 204 and the microphone 203.
[0028] In use, the end cap 101 can be connected to the pen holder 2, and the end cap 101 can cover the card reader 106. When talking to the patient, the PCB circuit board 204 is powered on by the control switch 201, and the conversation information is collected by the microphone 203. The voice information is then input into the memory card in the card reader 106 through the microphone head, voice IC and microcomputer. The memory card stores the recording information. When the conversation is over, the end cap 101 is separated from the pen holder 2, the card reader 106 is taken out, and the card reader 106 is archived together with the patient's medical record for easy retrieval later.
[0029] Furthermore, an elastic element 102 is provided on one side of the end cap 101, which can fix the device to the pocket opening or folder.
[0030] Furthermore, the data interface 207 is used for data transmission and charging of the built-in power supply, which is located in the pen holder 2 and can provide operating power for the device. It can also be charged repeatedly for continuous use.
[0031] Furthermore, the pen holder 2 is also equipped with a power indicator light 202, which can display the power level of the built-in power supply, making it convenient to charge the built-in power supply.
[0032] Please see Figure 3 as well as Figure 4 The top of the end cover 101 is also provided with an upper pressure holding pad 107 corresponding to the card reader 106. The card reader 106 is connected to the data interface 207, which can hide and fix the card reader 106. The two sides of the end cover 101 are also provided with snap-fit blocks 103, which correspond to snap-fit grooves 104. The snap-fit grooves 104 are symmetrically arranged on both sides of the outer surface of the pen holder 2, which facilitates the positioning and installation of the end cover 101 and the pen holder 2.
[0033] In use, first connect the card reader 106 to the data interface 101, then put the end cap 101 on the pen holder 2, and insert the card block 103 into the card slot 104. Push the end cap 101 down, and the end cap 101 will drive the card block 103 to move downward in the card slot 104. At the same time, the end cap 101 will drive the upper pressure holding pad 107 to move downward, and make the upper pressure holding pad 101 fit against the end of the card reader 106. The upper pressure holding pad 107 will press and fix the card reader 106. At the same time, the end cap 101 can completely hide the card reader 106, which can reduce the patient's vigilance. Specifically, the data interface 207 can be a USB interface or a Type-C interface.
[0034] Please see Figure 4The bottom of the snap-fit block 103 is also provided with a positioning snap-fit rod 108. One end of the positioning snap-fit rod 108 is snapped into the positioning slot 109. The positioning slot 109 is located at the bottom of the snap-fit groove 104, which can position and fix the snap-fit block 103.
[0035] When installing the snap-fit block 103, the positioning rod 108 is snapped into the positioning slot 109, which can replicate and position the snap-fit block 103, thus improving the fixation of the snap-fit block 103.
[0036] Please see Figure 4 An elastic retaining ring 110 is also provided in the positioning slot 109. The elastic retaining ring 110 corresponds to the annular slot 105, which is provided on the outer surface of the positioning rod 108, further improving the stability of the positioning rod 108 when it is fixed.
[0037] When the positioning rod 108 is inserted into the positioning slot 109, the positioning rod 108 compresses the elastic retaining ring 110. After the positioning rod 108 is fully inserted into the positioning slot 109, the elastic retaining ring 110 is inserted into the annular slot 105, thereby fixing the positioning rod 108 in the positioning slot 109.
[0038] Please see Figure 4 A pearl cotton pad 206 is also provided between the inner sleeve 205 and the pen holder 2. When the device is dropped, the pearl cotton pad 206 can absorb the vibration, thereby improving the drop resistance of the pen holder 2.
[0039] Please see Figure 5 One end of the pen barrel 3 is provided with an external threaded sleeve 31, which is connected to an internal thread 32. The internal thread 32 is located at the bottom of the pen holder 2, which allows the pen barrel 3 to be separated from the pen holder 2, making it easy to replace the pen refill 4.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
