Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a disposable sterile ultrasound probe sleeve. Background Technology
[0002] Medical ultrasound instruments are medical devices developed based on the principles of ultrasound and applied in the medical and health field for the diagnosis and treatment of diseases. A medical ultrasound diagnostic instrument mainly consists of two parts: the main unit and the ultrasound probe. The ultrasound probe can emit and receive ultrasound, perform electroacoustic signal conversion, transforming the electrical signals sent from the main unit into high-frequency oscillating ultrasound signals, and also converting the ultrasound signals reflected back from tissues and organs into electrical signals, which are then displayed on the main unit's monitor.
[0003] When performing invasive procedures, such as ultrasound-guided nerve blocks, combined spinal-epidural anesthesia, and intraoperative lesion localization, the ultrasound probe must be kept sterile to avoid cross-infection. To ensure sterility, a sterile glove is typically used to wrap the probe, and a sterile endoscope sheath is used to wrap the cables, with the connection between the glove and the endoscope sheath secured. This method is complex and cumbersome, increases the operation time, and is highly susceptible to contamination, leading to postoperative infection in patients.
[0004] How to provide a convenient, disposable, sterile ultrasonic probe cover is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a disposable sterile ultrasonic probe sleeve, so as to solve at least one of the above-mentioned technical problems.
[0006] To solve the above-mentioned technical problems, this utility model provides a disposable sterile ultrasound probe sleeve, comprising: a cable protection assembly, which includes a cylindrical sleeve, a pull ring, and several hanging ropes; the diameter of the pull ring is adapted to the diameter of one end of the cylindrical sleeve, and the pull ring is sleeved on one end of the cylindrical sleeve; the length of the hanging ropes is not less than the length of the cylindrical sleeve, and several hanging ropes are evenly spaced on the pull ring; and a probe protection assembly, which includes a probe protection sleeve, the shape of which is adapted to the shape of the ultrasound probe, and the open end of the probe protection sleeve is connected to the other end of the cylindrical sleeve.
[0007] Optionally, the probe protective sleeve is frustum-shaped, and the bottom end of the probe protective sleeve is connected to the other end of the cylindrical sleeve.
[0008] Optionally, there are two hanging ropes, both of which are longer than twice the length of the tubular sleeve. The two ends of one hanging rope are installed at a distance from each other on one side of the pull ring, and the two ends of the other hanging rope are installed at a distance from each other on the other side of the pull ring.
[0009] Optionally, each of the hanging ropes is provided with a pull rod in the middle.
[0010] Optionally, the cylindrical sleeve includes a winding section and a connecting section, both of which are frustum-shaped. The bottom diameters of the winding section and the connecting section are the same, and the bottom end of the winding section is connected to the bottom end of the connecting section. The other end of the protruding section is connected to the top end of the connecting section, and the pull ring is sleeved on the top end of the winding section.
[0011] Optionally, the top diameter of the winding section is 12cm, and the bottom diameters of the connecting section and the winding section are both 10cm.
[0012] Optionally, each of the hanging ropes has a flat cross-section.
[0013] Optionally, the pull ring is made of a rigid material, and the probe protective sleeve is made of medical-grade rubber.
[0014] Optionally, the tubular sleeve is made of medical-grade polypropylene.
[0015] Beneficial effects:
[0016] This utility model provides a disposable sterile ultrasonic probe sleeve. When not in use, the pull ring on the cylindrical sleeve rolls along the body of the sleeve towards one end of the probe protective sleeve. The body of the cylindrical sleeve rolls up with the pull ring until it reaches the probe protective sleeve. Simultaneously, the hanging rope is arranged parallel to the cylindrical sleeve and is rolled inside the sleeve as it rolls up. The length of the hanging rope is not less than the length of the cylindrical sleeve, so a section of the rope remains outside the rolled-up sleeve. When protection of the ultrasonic probe is needed, the probe protective sleeve is first placed on the ultrasonic probe, with the pull ring and the body of the cylindrical sleeve positioned on one side of the ultrasonic probe's cable. The operator, wearing sterile gloves, holds the probe protective sleeve. The device consists of a sleeve and an ultrasound probe. An assistant pulls on a portion of the extended hanging ropes towards the ultrasound probe cable. As the ropes are pulled, the rolled-up cylindrical sleeve flips outwards, and the pull rings continue to roll until they are fully exposed. At this point, the pull rings are positioned at the ultrasound probe cable, and the cylindrical sleeve effectively protects both the handheld portion of the ultrasound probe and the cable. This device has a simple structure, occupies little space when rolled up, is easy to store, and is simple to operate—simply pull the hanging ropes. The cylindrical sleeve and probe protective sleeve protect and isolate the ultrasound probe and cable, preventing direct contact between the ultrasound probe and the patient during each use and avoiding cross-infection caused by different patients using the device.

[0027] Please see Figure 1-3This embodiment provides a disposable sterile ultrasound probe sleeve, which includes a cable protection assembly 1, comprising a cylindrical sleeve 11, a pull ring 12, and several hanging ropes 13; the diameter of the pull ring 12 is adapted to the diameter of one end of the cylindrical sleeve 11, and the pull ring 12 is sleeved on one end of the cylindrical sleeve 11; the length of the hanging ropes 13 is not less than the length of the cylindrical sleeve 11, and several hanging ropes 13 are evenly spaced on the pull ring 12; and a probe protection assembly 2, comprising a probe protection sleeve 21, the shape of which is adapted to the shape of the ultrasound probe, and the open end of the probe protection sleeve 21 is connected to the other end of the cylindrical sleeve 11.
[0028] Specifically, when not in use, the pull ring 12 on the cylindrical sleeve 11 of the ultrasound probe sleeve rolls along the body of the cylindrical sleeve 11 toward one end of the probe protective sleeve 21. The body of the cylindrical sleeve 11 rolls up with the pull ring 12 until it reaches the probe protective sleeve 21. At the same time, the hanging rope 13 is also arranged parallel to the cylindrical sleeve 11. When the cylindrical sleeve 11 rolls up, it is rolled inside the cylindrical sleeve 11. The length of the hanging rope 13 is not less than the length of the cylindrical sleeve 11, so a section of the hanging rope 13 is still outside the rolled-up cylindrical sleeve 11. When it is necessary to protect the ultrasound probe, first, the probe protective sleeve 21 is placed on the ultrasound probe. The pull ring 12 and the body of the cylindrical sleeve 11 are located on one side of the ultrasound probe cable. The operator wears sterile gloves, holds the probe protective sleeve and the ultrasound probe, and assists... The assistant pulls on a portion of the extended hanging ropes towards the ultrasound probe cable. The probe protective sleeve 21 is secured to the ultrasound probe. When the hanging rope 13 is pulled, the rolled-up cylindrical sleeve 11 flips outward along with the hanging rope 13, and the pull ring 12 rolls continuously until the pull ring 12 is fully exposed and the cylindrical sleeve 11 is also fully exposed. At this point, the pull ring 12 is located at the ultrasound probe cable, and the cylindrical sleeve 11 completes the wrapping and protection of the ultrasound probe's handle and cable. This device has a simple structure, occupies little space when rolled up, is easy to store, and is simple to operate when in use; simply pull the hanging rope 13. The cylindrical sleeve 11 and the probe protective sleeve 21 complete the protection and isolation of the ultrasound probe and cable, ensuring that the ultrasound probe does not directly contact the patient during each use, thus avoiding cross-infection caused by different patients using it.
[0029] In some possible implementations, the probe protective sleeve 21 is frustum-shaped, and the bottom end of the probe protective sleeve 21 is connected to the other end of the cylindrical sleeve 11.
[0030] Specifically, the tip of a conventional ultrasound probe has a protruding circular plate. Therefore, the probe protective sleeve 21 is shaped like a frustum. The protruding circular plate fits inside the bottom of the frustum, i.e., the side with the larger diameter of the frustum. In use, the tip of the ultrasound probe is inserted from the cylindrical sleeve 11 into the probe protective sleeve 21. The probe protective sleeve 21 is inserted from the tip. The material of the probe protective sleeve 21 has a certain degree of elasticity, which can support the protruding part of the probe to be inserted. This shape of the probe protective sleeve 21 fits the ultrasound probe better.
[0031] In some possible implementations, there are two hanging ropes 13, each longer than twice the length of the tubular sleeve 11. The two ends of one hanging rope 13 are spaced apart and installed on one side of the pull ring 12, while the two ends of the other hanging rope 13 are spaced apart and installed on the other side of the pull ring 12. A pull rod 121 is provided in the middle of each hanging rope 13.
[0032] Specifically, two hanging ropes 13 are located on either side of the pull ring 12, with both ends of each rope 13 connected to the pull ring 12. The four ends of the two hanging ropes 13 are evenly distributed on the pull ring 12, and the middle of each rope 13 extends to one end of the rubber ring of the tubular sleeve 11. When the tubular sleeve 11 is rolled up, the middle of each hanging rope 13 is outside the rolled-up ring of the tubular sleeve 11. In use, medical staff pull the middle of both hanging ropes 13 simultaneously, and the four sections of the two hanging ropes 13 simultaneously unfold the tubular sleeve 11, resulting in a more even unfolding of the tubular sleeve 11. When medical staff pull the hanging ropes 13, they can also pull the lever 121, which is more convenient to use.
[0033] In some possible implementations, the cylindrical sleeve 11 includes a take-up section 111 and a connecting section 112. Both the take-up section 111 and the connecting section 112 are frustoconical. The bottom diameters of the take-up section 111 and the connecting section 112 are the same. The bottom end of the take-up section 111 is connected to the bottom end of the connecting section 112. The other end of the probe section 212 is connected to the top end of the connecting section 112. The pull ring 12 is sleeved on the top end of the take-up section 111.
[0034] Specifically, the diameter of the bottom end of the frustum is larger than that of the top end. The cylindrical sleeve 11 is divided into a winding section 111 and a connecting section 112. The winding section 111 needs to be wound up with the pull ring 12. As the pull ring 12 continuously rolls up, the cylindrical sleeve 11 on the pull ring 12 continuously thickens, and the diameter of the pull ring 12 and the cylindrical sleeve 11 on the pull ring 12 continuously increases. The cylindrical sleeve 11 away from the pull ring 12 needs to be continuously wound onto the cylindrical sleeve 11 on the pull ring 12. Therefore, the distance from the pull ring 12... The further away the cylindrical sleeve 11 is, the wider it will be stretched. When the winding section 111 is frustum-shaped, the end with the smaller diameter of the frustum is connected to the pull ring 12, and the end with the larger diameter of the frustum is away from the pull ring 12. When the pull ring 12 drives the cylindrical sleeve 11 to roll up, the winding section 111 of the cylindrical sleeve 11 will not be stretched open due to the increasing diameter of the cylindrical sleeve 11 on the pull ring 12, resulting in damage or other issues. The connecting section 112 is relatively short and does not need to be rolled up. It is connected to the ultrasonic probe sleeve.
[0035] In some possible implementations, the top diameter of the take-up section 111 is 10 cm, and the bottom diameters of both the connecting section 112 and the take-up section 111 are 12 cm.
[0036] Specifically, the winding section 111 is a cylinder with a top diameter of 10cm and a bottom diameter of 12cm, which can meet the need for increasing the winding diameter. Correspondingly, the connecting section 112 is connected to the winding section 111 at one end with a diameter of 12cm. The top 10cm of the winding section 111 can accommodate the cable and the ultrasonic probe.
[0037] In some possible implementations, the cross-section of each hanging rope 13 is flat.
[0038] Specifically, the hanging rope 13 has a flat cross-section, and when the tubular sleeve 11 is rolled up, the flat surface is in close contact with the tubular sleeve 11. The hanging rope 13 will not protrude too much inside the tubular sleeve 11, causing the rolled-up tubular sleeve 11 to be uneven, and thus the tubular sleeve 11 to wrinkle.
[0039] In some possible implementations, the pull ring 12 is made of a rigid material, and the probe protective sleeve 21 is made of medical-grade rubber. The cylindrical sleeve 11 is made of medical-grade polypropylene.
[0040] Specifically, when the pull ring 12 is made of a rigid material, the cylindrical sleeve 11 will not deform due to pressure when rolled onto the pull ring 12; the rubber material has a certain degree of elasticity, which can meet the needs of ultrasound probes of different sizes, and can also fit better with the ultrasound probe. The medical-grade polyethylene material is not easily damaged.
