Description

Technical Field

[0001] This application relates to the field of irrigation devices, specifically to an irrigation device for surgical care. Background Technology

[0002] In surgery, patients often have open wounds due to injury or surgery. In daily care, it is necessary to frequently rinse and disinfect the wounds to prevent infection and worsening of the wounds.

[0003] In existing technologies, when rinsing and disinfecting small wounds, a larger syringe, such as a 20ml or 50ml syringe, is used to draw undiluted alcohol or hydrogen peroxide disinfectant, and then add saline solution to prepare a disinfectant solution before rinsing and disinfecting the patient's wound. However, after the syringe has drawn up the alcohol and saline solution, it is necessary to draw in air and shake the syringe to mix the alcohol and saline solution before it can be used. However, the shaking motion is quite large, which can easily cause the syringe to come into contact with and collide with other objects, resulting in contamination of the syringe or waste of disinfectant solution. Therefore, this application provides a surgical nursing rinsing device to improve this problem. Utility Model Content

[0004] The purpose of this application is to provide a surgical irrigation device to address the problems mentioned above.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution: A surgical irrigation device, comprising: A receiving cylinder having a receiving cavity and an outlet, wherein a piston rod is slidably installed in the receiving cavity and a needle is movably inserted into the outlet; A sliding cavity is formed on the piston rod, a drive rod is movably installed in the sliding cavity, a stirring blade is installed on the drive rod, a spiral groove is formed in the sliding cavity, a protrusion is installed on the drive rod that movably cooperates with the spiral groove, and a receiving groove for receiving the stirring blade is formed on one end of the piston rod located in the receiving cavity.

[0006] Furthermore, the protrusion is a ball that is rolled on the drive rod, and the ball is in movable engagement with the helical groove.

[0007] Furthermore, an expansion block is installed on the drive rod, and there is a gap between the expansion block and the piston rod for the movement of the drive rod. A drive disk is movably installed on the expansion block, and an eccentric rod is hinged on the drive disk. An abutment plate is hinged on the free end of the eccentric rod. When the abutment plate is inserted into the gap, the movement of the drive rod on the piston rod is restricted.

[0008] Furthermore, a clamping groove is provided on the piston rod, and a guide rod is slidably installed in the clamping groove. The guide rod is connected to the abutment plate. When the abutment plate is inserted into the gap, the projection of the guide rod on the receiving cylinder is located in the receiving cavity. When the abutment plate is separated from the gap, the guide rod abuts against the receiving cavity along the edge.

[0009] Furthermore, a fixing rod is installed on the enlarged block, and a rubber block is installed on the drive disk. The rubber block has a fixing hole for accommodating the fixing rod. When the fixing hole accommodates the fixing rod, the rotation of the drive disk on the enlarged block is restricted.

[0010] Furthermore, a rotating plate is rotatably mounted inside the receiving cavity, and a return spring is mounted on the rotating plate. The free end of the return spring is rotatably connected to the drive rod.

[0011] Furthermore, an extension block is installed on the end of the guide rod away from the contact plate, and the cross-sectional area of ​​the extension block facing the receiving cavity is larger than the cross-sectional area of ​​the guide rod facing the receiving cavity.

[0012] Furthermore, a lifting knob is slidably mounted on the drive disk, and the lifting knob causes a protrusion to form on the drive disk.

[0013] The beneficial effects of this application are as follows: In use, this device draws saline and alcohol into the receiving cavity by sliding the piston rod. By pulling and pushing the drive rod, the protrusion on the drive rod guides the spiral groove, causing the drive rod to slide and rotate within the sliding cavity. This, in turn, drives the stirring blade to rotate within the receiving cavity, stirring the saline and alcohol. This allows medical staff to evenly mix the disinfectant without significant shaking, increasing the device's practicality. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0016] Example 1 like Figures 1-6 As shown, the surgical irrigation device proposed in Embodiment 1 of this application includes: The receiving tube 1 has a receiving cavity 101 and an outlet 102. A piston rod 103 is slidably installed in the receiving cavity 101, and a needle 104 is movably inserted into the outlet 102. The connection between the needle 104 and the outlet 102 is the same as the connection between the existing needle tube and the needle tip. It is installed or removed by inserting and pulling. When the device draws alcohol or saline, the needle 104 is inserted into the saline or alcohol bottle and the piston rod 103 is pulled to draw the saline or alcohol into the receiving cavity 101. After the drawing is completed, the needle 104 is removed. A sliding cavity 2 is formed on the piston rod 103 and passes through the piston rod 103. A drive rod 201 is movably installed in the sliding cavity 2 and can rotate and slide in the sliding cavity 2. A stirring blade 202 is mounted on the drive rod 201, and a spiral groove 203 is formed in the sliding cavity 2 to... Figure 1 From the main viewpoint, the receiving cavity 101 has a straight groove that communicates with the spiral groove 203 at one end of the spiral groove 203 that is vertically upward; The drive rod 201 is equipped with a protrusion that movably engages with the spiral groove 203. When not in use, the protrusion is located within the straight groove. The piston rod 103 has a receiving groove 105 at one end of the receiving cavity 101 for accommodating the stirring blade 202. In use, the drive rod 201 is first pushed, causing it to move the protrusion from the straight groove into the spiral groove 203. At this time, the stirring blade 202 moves from the receiving groove 105 into the receiving cavity 101. When the drive rod 201 is pulled or moved within the sliding cavity 2, the protrusion slides within the spiral groove 203. The spiral groove 203 guides the protrusion, causing the drive rod 201 to rotate. This causes the drive rod 201 to drive the stirring blade 202 to rotate and stir within the receiving cavity 101, thus increasing the uniform mixing of alcohol and saline in the receiving cavity 101. During injection, the drive rod 201 is pulled, causing the protrusion to move back into the straight groove, and the stirring blade 202 to return to the receiving groove 105. This allows the piston rod 103 to form a complete end within the receiving cavity 101, facilitating the piston rod 103 to push the disinfectant solution. This device is used on a single patient and remains in use for an extended period while the patient's wound is not yet healed. The device also includes a needle cap to protect the needle 104. When removing the needle 104, the needle cap is placed over it, covering only the metal part of the needle 104 used for puncture. The connection between the needle 104 and the outlet 102 remains exposed, similar to the structure of existing syringes. Removing the needle 104 involves pulling on its exposed portion. The needle 104 is separated from the outlet 102. Since the needle 104 and the outlet 102 are plugged in, the needle 104 should be replaced separately during long-term use. When the device is in use, the corresponding patient name, hospital number and bed number should be written on the outside of the container 1 with a marker to avoid mixing up the devices. After use, the container 1 should also be soaked in the disinfectant in the treatment room. The container 1 itself is also used to store the disinfectant, which reduces the possibility of cross-infection between patients during the use of the device. Compared with existing technologies, in use, after the saline and alcohol are drawn into the receiving cavity 101 by the sliding of the piston rod 103, the drive rod 201 is pulled and pushed. The protrusion on the drive rod is guided by the spiral groove 203, causing the drive rod 201 to slide and rotate in the sliding cavity 2. In turn, the drive rod 201 drives the stirring blade 202 to rotate in the receiving cavity 101, stirring the saline and alcohol. This allows medical staff to stir the disinfectant evenly without shaking it vigorously, increasing the practicality of the device.

[0017] Example 2 like Figure 4As shown, Embodiment 2 further discloses the protrusion, drive rod 201, and piston rod 103 based on Embodiment 1. In Embodiment 2, the protrusion is a ball 3 that is rolled on the drive rod 201. The ball 3 is movably engaged with the spiral groove 203. When the drive rod 201 moves in the sliding cavity 2, the ball 3 on it rolls in the spiral groove 203, which reduces the friction between the drive rod 201 and the spiral groove 203, reduces the resistance encountered by the drive rod 201 during movement, and increases the convenience of the device in use.

[0018] like Figure 2 As shown, in Embodiment 2, an enlarged block 5 is installed on the drive rod 201. There is a gap between the enlarged block 5 and the piston rod 103 for the movement of the drive rod 201. The diameter of the enlarged block 5 is larger than the diameter of the drive rod 201, so that there is a gap between the bottom of the enlarged block 5 and the top of the piston rod 103. This gap is the range of movement of the drive rod 201 in the sliding cavity 2. A drive disc 4 is movably mounted on the enlarged block 5, allowing it to rotate and slide on the enlarged block 5. An eccentric rod 6 is hinged to the drive disc 4, and a contact plate 7 is hinged to the free end of the eccentric rod 6. When the contact plate 7 is inserted into the gap, the movement of the drive rod 201 on the piston rod 103 is restricted. When the device needs to slide the piston rod 103 to spray disinfectant, the contact plate 7 is located in the gap, with one side of the contact plate 7 contacting the bottom of the enlarged block 5 and the other side contacting the top of the piston rod 103, thus restricting the tendency of the drive rod 201 to move into the receiving cavity 101. At this time, the stirring blade 202 is located in the receiving groove 10. Inside the cavity 105, the inner wall of the receiving tank 105 blocks the stirring blade 202, thereby restricting the movement of the drive rod 201 away from the receiving cavity 101, and thus restricting the movement of the drive rod 201. This prevents the drive rod 201 from affecting the movement of the piston rod 103, increasing the feasibility of the device. When it is necessary to mix and stir the disinfectant, the drive disc 4 is rotated to drive the eccentric rod 6 to rotate, causing the eccentric rod 6 to push the contact plate 7 out of the gap, thus releasing the blockage of the expansion block 5, allowing the drive rod 201 to move smoothly in the sliding cavity 2, further increasing the feasibility of the device.

[0019] like Figure 2 and Figure 3 As shown, in Embodiment 2, a groove 8 is provided on the piston rod 103, and a guide rod 9 is slidably installed in the groove 8. The side wall of the guide rod 9 contacts the inner wall of the groove 8 to guide the movement of the abutment plate 7, so that the abutment plate 7 can only move closer to or away from the gap in a straight line, thereby increasing the stability of the abutment plate 7 during movement. The guide rod 9 is connected to the contact plate 7. When the contact plate 7 is inserted into the gap, the projection of the guide rod 9 on the receiving cylinder 1 is located in the receiving cavity 101. When the contact plate 7 is separated from the gap, the guide rod 9 abuts against the receiving cavity 101 along the edge. When the contact plate 7 is located in the gap, when the piston rod 103 is pushed, the guide rod 9 can be smoothly inserted into the receiving cavity 101. At this time, the guide rod 9 will not restrict the movement of the piston rod 103. When the contact plate 7 is separated from the gap, the contact plate 7 drives the guide rod 9 to move away from the drive rod 201, and the shape of the receiving cylinder 1 is as follows: Figure 1 As shown, the side of the syringe away from the outlet 102 is consistent with the existing syringe and has a wing plate, which allows the guide rod 9 to move to a position that abuts against the wing plate. The contact between the guide rod 9 and the wing plate prevents the piston rod 103 from moving into the receiving cavity 101. When the drive rod 201 is pulled out, the drive rod 20 can move smoothly through the sliding between the drive disc 4 and the expansion block 5. At this time, the piston rod 103 cannot push the disinfectant to the outside of the receiving cylinder 1, which increases the stability of the piston rod 103 when stirring the disinfectant and reduces the possibility of disinfectant waste.

[0020] like Figure 2 As shown, in Embodiment 2, a fixing rod 10 is installed on the enlarged block 5, and a rubber block 11 is installed on the drive disk 4. The rubber block 11 has a fixing hole 12 for accommodating the fixing rod 10. When the fixing hole 12 accommodates the fixing rod 10, the rotation of the drive disk 4 on the enlarged block 5 is restricted. When the contact plate 7 is in the gap, the rubber block 11 is located away from the fixing rod 10. When the drive disk 4 is rotated so that the contact plate 7 is away from the gap, the drive disk 4 drives the rubber block 11 to move closer to the fixing rod 10. When the rubber block 11 moves to contact the fixing rod 10, the rubber block 11 deforms, causing the side wall of the fixing hole 12 to also deform until it can accommodate the fixing rod 10. At this time, the rotation of the drive disk 4 is restricted, so that when the drive rod 201 is pulled out, the drive disk 4 will not rotate arbitrarily, so that the contact plate 7 will not be inserted into the gap again due to the movement of the drive rod 201, increasing the convenience of pulling out the drive rod 201.

[0021] Example 3 like Figures 1-6As shown, Embodiment 3 further discloses this application based on Embodiment 2. In Embodiment 3, a rotating plate 13 is rotatably installed inside the receiving cavity 101, and a return spring 14 is installed on the rotating plate 13. The free end of the return spring 14 is rotatably connected to the drive rod 201. The drive rod 201 includes a thick rod and a thin rod. The thick rod is connected to the stirring blade 202, and the thin rod is connected to the expanding block 5. A bearing connected to the return spring 14 is rotatably installed at the connection between the thick rod and the thin rod, so that the return spring 14 is rotatably connected to the drive rod 201. When driving the drive rod 201, it is only necessary to press the drive rod. Releasing rod 201 resets the drive rod 201 by pulling the return spring 14, increasing the convenience of the device. At this time, in order to keep the ball 3 in the spiral groove 203, the return spring 14 is not fully reset. Since the original length of the return spring 14 and the length of the spiral groove 203 are fixed, when the return spring 14 is fully reset, it will pull the stirring blade 202 back into the receiving groove 105. There is no need to carefully rotate or slide the drive rod 201 to align the stirring blade 202 with the receiving groove 105 before storing the stirring blade 202, which increases the practicality of the device.

[0022] In Embodiment 3, in some embodiments, an extension block 15 is installed on the end of the guide rod 9 away from the contact plate 7. The cross-sectional area of ​​the extension block 15 on the side facing the receiving cavity 101 is larger than the cross-sectional area of ​​the guide rod 9 on the side facing the receiving cavity 101. When the guide rod 9 abuts against the wing plate of the receiving cylinder 1, the extension block 15 increases the connection area between the two, thereby increasing the stability of the guide rod 9 during use.

[0023] In Embodiment 3, in some embodiments, a lifting button 16 is slidably mounted on the drive disk 4. The lifting button 16 causes a protrusion on the drive disk 4. A φ-shaped block is mounted on the lifting button 16, and a φ-shaped hole is opened on the drive disk 4, so that the lifting button 16 and the drive disk 4 can slide together without rotating relative to each other. When the lifting button 16 rotates, it can drive the drive disk 4 to rotate. The lifting button 16 passes through the drive disk 4 and is connected to the enlarged block 5. Medical staff can rotate the drive disk 4 by squeezing the lifting button 16, thereby enabling medical staff to use the device, which increases the convenience of the device. Pressing the lifting button 16 drives the drive rod 201, which also increases the convenience of the device.
