Description

Technical Field

[0001] This invention relates to the field of medical device technology, and specifically to a leak-proof mechanism for puncture needles with an alarm mechanism. Background Technology

[0002] Puncture techniques occupy a pivotal position in modern medicine, widely used in various diagnostic and treatment scenarios. From routine blood draws to provide crucial data for the initial diagnosis of diseases, to in-depth tissue biopsies to obtain diseased tissue samples for precise pathological analysis, to the drainage of various body cavity effusions or gas accumulations to alleviate the discomfort and potential risks caused by fluid or gas retention, and to the precise injection of drugs into body cavities for treatment, puncture plays an irreplaceable role. In these procedures, the puncture needle, as the core tool, comes into direct contact with human tissues and internal body fluids or drugs.

[0003] However, the existing technology has the following problems: In current treatment techniques using puncture needles, the needles need to penetrate multiple layers of tissue, including skin and muscle, creating a wound at the puncture site. This creates a risk of fluid leakage. In some treatments, the needle needs to remain relatively still within the body for a period of time. During this time, patient movement and external forces can cause the needle to dislodge. When the needle moves outwards, it disturbs the wound, increasing the probability of fluid leakage. If significant fluid leakage is not addressed promptly, it can contaminate the surgical area, increasing the risk of infection and causing patient discomfort. Furthermore, due to the busy schedules of medical staff, they sometimes cannot immediately detect and address fluid leakage at the puncture site. Summary of the Invention

[0004] The purpose of this invention is to provide a puncture needle anti-leakage mechanism with an alarm system to solve the above-mentioned problems. It aims to overcome the shortcomings of the prior art in actual treatment, where medical staff sometimes cannot detect and deal with fluid leakage at the puncture site in a timely manner. Details are described below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a puncture needle anti-leakage mechanism with an alarm system, comprising a base plate to which a housing is connected, and a detachment alarm component for triggering an alarm when the puncture needle displaces or falls off; and a leakage alarm component for triggering an alarm when bodily fluid leaks from the wound. The detachment alarm component includes a mounting bracket mounted on the base plate, on which a first rotating rod and a second rotating rod are rotatably mounted. The first rotating rod is positioned above the second rotating rod, and a sliding shaft is connected through the bottom end of the first rotating rod. When the sliding shaft moves, it contacts the upper half of the second rotating rod. A contact rod is connected to the bottom end of the second rotating rod. A touch alarm is mounted on the base plate, and the contact rod contacts the touch alarm when it moves. The detachment alarm component also includes a clamping part for clamping and fixing the puncture needle onto the first rotating rod.

[0006] Preferably, both the mounting bracket and the anti-touch alarm are inside the housing, and an external speaker is connected to the outer wall of the housing. The external speaker is connected to the touch alarm via a wire.

[0007] Preferably, the top surface of the housing is connected to a tray, and the top surface of the housing and the tray are provided with through grooves, and the top of the first rotating rod passes through the through grooves on the top surface of the housing and the tray.

[0008] Preferably, the clamping part includes a base, two side plates, two sets of connecting rods, and two anti-reverse plates. The base is connected to the top of the first rotating rod. Both side plates are connected to the base. The two sets of connecting rods are respectively hinged to the side of the two side plates closest to each other. The two anti-reverse plates are respectively hinged to the end of the two sets of connecting rods away from the side plates. The two anti-reverse plates are mirror images of each other. Springs are respectively connected to the side of the two anti-reverse plates away from each other. The ends of the two springs away from the anti-reverse plates are respectively connected to the two side plates.

[0009] Preferably, the clamping part further includes a limiting fork, which is slidably connected to the top surface of the housing, and the limiting fork slides in contact with the outer wall of the first rotating rod during movement.

[0010] Preferably, the leakage alarm component includes a movable box, a fixed box, a liquid hopper, a slider, and a light rod. The movable box and the fixed box are both mounted on the base plate. The movable box and the fixed box are slidably connected on the side away from the mounting frame. The liquid hopper is connected to the fixed box. The slider is slidably connected to the inner wall of the fixed box. The light rod is slidably connected through the fixed box on the side near the mounting frame. The movable box is filled with a super absorbent polymer material. The light rod contacts the bottom end of the second rotating rod during movement.

[0011] Preferably, the leakage alarm assembly further includes a movable plate, a portion of the liquid hopper being located outside the housing, the movable plate being hinged to the top of the liquid hopper at an edge away from the housing.

[0012] Preferably, the leakage alarm component further includes a filter screen, and the bottom of the liquid hopper is provided with an outlet, with the filter screen connected to the outlet of the liquid hopper.

[0013] Preferably, the leakage alarm component further includes a conical groove plate and a frustum plate. The conical groove plate is connected to the outlet of the liquid hopper, and the frustum plate is connected to the inner wall of the movable box. The conical groove plate is located below the filter screen, and the frustum plate is located below the conical groove plate. The conical groove plate is provided with two frustum-shaped grooves, and the frustum plate is provided with two frustum blocks and multiple leakage grooves. During the movement, the two frustum blocks on the frustum plate are in contact with the two frustum-shaped grooves of the conical groove plate.

[0014] The beneficial effects are: 1. This puncture needle anti-leakage mechanism with an alarm system, through the setting of the detachment alarm component, ensures that after the clamping part holds the puncture needle, when the puncture needle moves in the direction outside the body, the first rotating rod, the second rotating rod, and the contact rod work together to trigger the touch alarm, prompting medical staff to come and handle the situation immediately, thus preventing leakage of bodily fluids due to puncture needle displacement; through the setting of two anti-reverse plates, the two anti-reverse plates can prevent the puncture needle from moving in the opposite direction when the medical staff releases it, thereby disturbing the wound and increasing the probability of bodily fluid leakage.

[0015] 2. This puncture needle anti-leakage mechanism with an alarm system, through the setting of the leakage alarm component, allows the slider to indirectly trigger the touch alarm by utilizing the expansion force of the superabsorbent polymer material after the patient's puncture fluid leaks out, prompting medical staff to come and handle the situation. This ensures that the touch alarm can still sound in a timely manner even if the puncture needle does not shift and leakage occurs. Through the cooperation of the conical groove plate and the frustum plate, when the superabsorbent polymer material expands, the conical groove plate and the frustum plate can fit together and seal, thereby allowing the patient's body fluid to be temporarily retained in the liquid tank for collection, facilitating subsequent cleaning and disinfection, and reducing the area of ​​body fluid contamination.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] Example 1 Please see Figure 1 - Figure 11A leak-proof mechanism for a puncture needle with an alarm system includes a base plate 1, a housing 2 connected to the base plate 1, and a detachment alarm assembly 4 for triggering an alarm when the puncture needle displaces or detaches. The detachment alarm assembly 4 includes a mounting bracket 41 mounted on the base plate 1. A first rotating rod 42 and a second rotating rod 44 are rotatably mounted on the mounting bracket 41. The first rotating rod 42 is located above the second rotating rod 44. A sliding shaft 43 is connected through the bottom end of the first rotating rod 42. When the sliding shaft 43 moves, it contacts the upper half of the second rotating rod 44. A contact rod 45 is connected to the bottom end of the second rotating rod 44. A touch alarm 7 is mounted on the base plate 1. When the contact rod 45 moves, it contacts the touch alarm 7. The alarm 7 is in contact with the external speaker 7. Both the mounting bracket 41 and the anti-touch alarm 7 are inside the housing 2. An external speaker 8 is connected to the outer wall of the housing 2. The external speaker 8 is connected to the touch alarm 7 via a wire. When the first rotating rod 42 swings clockwise, it drives the second rotating rod 44 to swing counterclockwise through the sliding shaft 43. During the rightward movement of the contact rod 45 at the bottom of the second rotating rod 44, it contacts the touch alarm 7. The touch alarm 7 transmits a signal to the external speaker 8, which then sounds an alarm to alert medical staff to handle the dislodged puncture needle immediately. The touch alarm 7 can also be wirelessly connected to the monitoring equipment at the nurse station. When the alarm is triggered, the nurse station can also receive the alarm signal and handle the situation promptly.

[0021] Furthermore, a tray 3 is connected to the top surface of the housing 2, and through slots are provided on the top surface of the housing 2 and the tray 3. The top of the first rotating rod 42 passes through the through slots on the top surface of the housing 2 and the tray 3. The housing 2 serves to protect the detachment alarm component 4, and the tray 3 can hold some medical tools for easy access by medical staff.

[0022] Furthermore, the detachment alarm assembly 4 also includes a clamping part 5 for clamping and fixing the puncture needle to the first rotating rod 42. The clamping part 5 includes a base 51, two side plates 52, two sets of connecting rods 53, and two anti-reverse plates 54. The base 51 is connected to the top of the first rotating rod 42, and the two side plates 52 are both connected to the base 51. The two sets of connecting rods 53 are respectively hinged to the side of the two side plates 52 closest to each other, and the two anti-reverse plates 54 are respectively hinged to the end of the two sets of connecting rods 53 away from the side plates 52. 54 is a mirror image configuration. Springs are connected to the sides of the two anti-reverse plates 54 furthest from each other. The ends of the springs furthest from the anti-reverse plates 54 are connected to the two side plates 52. When the puncture needle moves to the right, it causes the two anti-reverse plates 54 to move to the right. The two anti-reverse plates 54, through the two side plates 52 and the base 51, cause the top end of the first rotating rod 42 to move to the right. The clamping part 5 also includes a limiting fork 55, which is slidably connected to the top surface of the housing 2. During movement, the limiting fork 55 slides in contact with the outer wall of the first rotating rod 42. Under normal conditions, the limiting fork 55 does not contact the first rotating rod 42. After the limiting fork 55 is pushed forward, it limits the first rotating rod 42, allowing the puncture needle to move to the left between the two anti-reverse plates 54, thus slowly penetrating the patient's body. When the puncture needle moves to the right, the two anti-reverse plates 54 clamp the puncture needle, preventing it from moving further to the right. Therefore, the puncture needle can only slide to the left between the two anti-reverse plates 54, which prevents the puncture needle from moving in the opposite direction. Through the setting of the detachment alarm component 4, the clamping part 5 clamps the puncture needle. Subsequently, when the puncture needle moves outward, the first rotating rod 42, the second rotating rod 44, and the contact rod 45 work together to trigger the touch alarm 7, prompting medical staff to come and handle the situation immediately to avoid leakage of bodily fluids due to needle displacement. The two anti-reverse plates 54 prevent the needle from moving backward during puncture treatment, thus preventing the needle from moving backward when the medical staff releases it, thereby disturbing the wound and increasing the probability of bodily fluid leakage.

[0023] In addition, the leakage alarm component 6 is used to trigger an alarm when bodily fluids leak from the wound. The leakage alarm component 6 includes a movable box 61, a fixed box 62, a liquid hopper 63, a slider 66, and a smooth rod 67. The movable box 61 and the fixed box 62 are both mounted on the base plate 1. The movable box 61 and the fixed box 62 are slidably connected on the side away from the mounting frame 41. The liquid hopper 63 is connected to the fixed box 62. The slider 66 is slidably connected to the inner wall of the fixed box 62. The smooth rod 67 is slidably connected through the fixed box 62 on the side near the mounting frame 41. The movable box 61 is filled with a super absorbent polymer material. During the movement, the smooth rod 67 contacts the bottom end of the second rotating rod 44. The super absorbent polymer material in the movable box 61 can expand when it comes into contact with water. After the super absorbent polymer material expands, it squeezes the slider 66 to the right, causing the slider 66 to move the smooth rod 67 to the right. During the movement of the smooth rod 67 to the right, it contacts the bottom end of the second rotating rod 44. The second rotating rod 44 moves the abutment rod 45 to the right, triggering the touch alarm 7.

[0024] In addition, the leakage alarm component 6 also includes a movable plate 64. A portion of the liquid hopper 63 is located outside the housing 2. The movable plate 64 is hinged to the top edge of the liquid hopper 63 away from the housing 2. The movable plate 64 can swing left and right. By manually swinging the movable plate 64, the movable plate 64 can be placed on the patient. When bodily fluid leaks out, the bodily fluid flows down the patient's skin onto the movable plate 64, and the movable plate 64 then guides the bodily fluid into the liquid hopper 63, preventing the bodily fluid from contaminating the operating table along the patient's skin.

[0025] It is worth noting that the leakage alarm component 6 also includes a filter screen 65. The bottom of the liquid hopper 63 is provided with an outlet, and the filter screen 65 is connected to the outlet of the liquid hopper 63. The filter pores of the filter screen 65 are smaller than the particle size of the superabsorbent polymer. Therefore, when the superabsorbent polymer expands, it will not be squeezed into the liquid hopper 63 through the filter screen 65, thereby ensuring the squeezing effect of the superabsorbent polymer on the slider 66.

[0026] It is worth noting that the leakage alarm component 6 also includes a conical groove plate 68 and a frustum plate 69. The conical groove plate 68 is connected to the outlet of the liquid hopper 63, and the frustum plate 69 is connected to the inner wall of the movable box 61. The conical groove plate 68 is located below the filter screen 65, and the frustum plate 69 is located below the conical groove plate 68. The conical groove plate 68 is provided with two frustum-shaped grooves, and the frustum plate 69 is provided with two frustum blocks and multiple leakage grooves. During movement, the two frustum blocks on the frustum plate 69 are in contact with the two frustum-shaped grooves on the conical groove plate 68. When the superabsorbent polymer does not expand, the frustum plate 69 is located below the conical groove plate 68, with a certain gap between them. When the superabsorbent polymer expands, it pushes the frustum plate 69 upward, causing the two frustum blocks on the frustum plate 69 to move upward and engage with the two frustum blocks on the conical groove plate 68. When the frustum-shaped grooves are fitted together, the two frustum-shaped grooves and the two frustum-shaped blocks form a sealed fit. At this time, the frustum-shaped grooves are temporarily sealed, and the body fluid in the liquid hopper 63 cannot flow into the movable box 61. Through the setting of the leakage alarm component 6, after the body fluid punctured by the patient leaks, the slider 66 uses the expansion force of the super absorbent polymer material to indirectly trigger the touch alarm 7 to alarm, prompting medical staff to come and handle the situation. This ensures that even if the body fluid leaks without the puncture needle shifting, the touch alarm 7 can still sound an alarm in a timely manner. Through the cooperation of the conical groove plate 68 and the frustum plate 69, when the super absorbent polymer material expands, the conical groove plate 68 and the frustum plate 69 can fit together and seal, so that the patient's body fluid is temporarily retained in the liquid hopper 63 for collection, which facilitates subsequent cleaning and disinfection and reduces the area of ​​body fluid contamination.

[0027] Using the above structure, the working principle of this case is as follows: the shell 2 provides protection, and the tray 3 can hold some medical tools for easy access by medical staff. During puncture treatment, the base plate 1 and the shell 2 are placed next to the puncture area. Taking the base plate 1 as the right side of the puncture area as an example, after the puncture needle is inserted, it is placed between the two anti-reverse plates 54. The anti-reverse plates 54 can apply slight pressure to the surface of the puncture needle through the elasticity of the spring. When the puncture needle falls out, it will move to the right. When the puncture needle moves to the right, the two connecting rods 53 will support the two anti-reverse plates 54, increasing the clamping force of the two anti-reverse plates 54 on the puncture needle. This causes the two anti-reverse plates 54 to move to the right when the puncture needle moves to the right. The two anti-reverse plates 54 are connected by two side... Plate 52 and base 51 drive the top of the first rotating rod 42 to move to the right, causing the first rotating rod 42 to swing clockwise. The sliding shaft 43 at the bottom of the first rotating rod 42 moves to the left. When the sliding shaft 43 moves to the left, it drives the second rotating rod 44 to swing counterclockwise. The abutment rod 45 at the bottom of the second rotating rod 44 moves to the right. During the rightward movement of the abutment rod 45, it contacts the touch alarm 7. The touch alarm 7 transmits a signal to the external speaker 8, which then sounds an alarm, prompting medical staff to come and handle the dislodged puncture needle immediately. The touch alarm 7 can also be wirelessly connected to the monitoring equipment at the nurses' station. When the alarm is triggered, the nurses' station can also receive the alarm signal, thus handling the situation promptly. When the puncture needle is inserted, medical staff can first clamp the outer wall of the puncture needle between two anti-reverse plates 5. In step 4, the limiting fork 55 is pushed forward. Normally, the limiting fork 55 does not contact the first rotating rod 42. After being pushed forward, the limiting fork 55 limits the first rotating rod 42, preventing it from swinging. The base 51 and the two side plates 52 also temporarily cannot move. When the puncture needle moves to the left on the two check plates 54, the connecting rod 53 can swing slightly towards the side plate 52. At this time, the connecting rod 53 does not provide support, allowing the puncture needle to move to the left between the two check plates 54, thus slowly penetrating the patient's body. However, when the puncture needle moves to the right, the connecting rod 53 swings towards the check plate 54, applying support. The two check plates 54 clamp the puncture needle, preventing it from continuing. The needle moves to the right, so it can only slide to the left between the two anti-reverse plates 54, which prevents the needle from moving in the opposite direction. During treatment, the needle may slip out of the hands of medical staff while they are performing punctures. The anti-reverse action of the two anti-reverse plates 54 can effectively prevent the needle from being moved out of the hands by external forces when it slips out of the hands, thus preventing the wound from being disturbed. With the setting of the detachment alarm component 4, when the puncture needle moves out of the hands after the clamping part 5 clamps the needle, the first rotating rod 42, the second rotating rod 44 and the contact rod 45 will trigger the touch alarm 7 to sound an alarm, prompting medical staff to come and deal with it as soon as possible, so as to avoid leakage of body fluid due to the displacement of the puncture needle.The two anti-reverse plates 54 ensure that during puncture treatment, they prevent the needle from moving backward and disturbing the wound, thus reducing the probability of fluid leakage.

[0028] The movable plate 64 can swing left and right. Manually swinging the movable plate 64 allows it to rest on the patient. When bodily fluids seep out, they flow along the patient's skin onto the movable plate 64, which then guides the fluid into the hopper 63. The hopper 63 then guides the fluid through an outlet into the movable box 61. The superabsorbent polymer material in the movable box 61 expands upon contact with water, pushing the slider 66 to the right. This causes the slider 66 to move the smooth rod 67 to the right. During this movement, the smooth rod 67 contacts the bottom of the second rotating rod 44, which in turn moves the abutment rod 45 to the right, triggering the touch alarm 7 and alerting medical personnel to intervene. The second rotating rod 44 itself does not... Since it contacts the sliding shaft 43, it will not cause the first rotating rod 42 to swing clockwise, nor will it disturb the puncture needle. Both the movable box 61 and the liquid hopper 63 are detachable for easy cleaning and disinfection, and also for easy replacement of the superabsorbent polymer material in the movable box 61. The filter screen 65 at the outlet of the liquid hopper 63 plays a filtering role, which can prevent some impurities or body fluid tissues from entering the movable box 61 along with the body fluid. At the same time, the filter pores of the filter screen 65 are smaller than the particle size of the superabsorbent polymer material. Therefore, when the superabsorbent polymer material expands, it will not be squeezed into the liquid hopper 63 through the filter screen 65, thus ensuring the squeezing effect of the superabsorbent polymer material on the slider 66. When the superabsorbent polymer material does not expand, the frustum plate 69 is located below the conical groove plate 68. There is a certain gap between the two. After passing through the filter screen 65, the body fluid falls onto the conical groove plate 68, and then falls onto the conical plate 69 through two frustoconical grooves. It then enters the movable box 61 through multiple leakage channels on the conical plate 69. When the superabsorbent polymer expands, it pushes the conical plate 69 upwards, causing the two frustoconical blocks on the conical plate 69 to move upwards and fit against the two frustoconical grooves of the conical groove plate 68. At this time, the two frustoconical grooves and the two frustoconical blocks form a sealed fit, temporarily sealing the conical grooves. This prevents the body fluid in the liquid hopper 63 from continuing to flow into the movable box 61, thus avoiding a large amount of body fluid flowing into the movable box 61 and causing it to overflow and contaminate the movable box 61. The base plate 1 and shell 2 around the fixed box 62 and the movable box 61 increase the workload of subsequent cleaning and disinfection. The leakage alarm component 6 enables the slider 66 to indirectly trigger the touch alarm 7 by utilizing the expansion force of the super absorbent polymer material after leakage of bodily fluid from the puncture, prompting medical staff to come and handle the situation. This ensures that the touch alarm 7 can still sound an alarm in a timely manner even if bodily fluid leakage occurs without displacement of the puncture needle. The cooperation of the conical groove plate 68 and the frustum plate 69 allows the conical groove plate 68 and the frustum plate 69 to fit and seal when the super absorbent polymer material expands, allowing the patient's bodily fluid to be temporarily collected in the liquid tank 63 for subsequent cleaning and disinfection, reducing the area of ​​bodily fluid contamination.
