[0001] The utility model relates to the field of medical apparatus and instruments, and specifically relates to a jejunum tube blockage dredging device. BACKGROUND

[0002] As an important medical instrument, the jejunum tube plays a key role in clinical nutrition support, drug treatment, etc. It can directly deliver nutrients, drugs, etc. to the jejunum of patients, providing necessary nutrient supply and drug treatment for patients, especially for those who cannot take nutrients through normal diet or need special drug treatment.

[0003] However, the jejunum tube is prone to blockage during use, mainly because the infusion of nutrients, drugs, etc. may contain particulate impurities, or chemical reactions occur between nutrients and drugs during infusion, producing precipitates. These impurities and precipitates will gradually adhere to the inner wall of the jejunum tube, and with the passage of time, the accumulation will continue to increase, eventually leading to stenosis or even complete blockage of the jejunum tube lumen. Once the jejunum tube is blocked, the infusion of nutrients and drugs will be hindered, and the normal treatment according to the predetermined treatment plan will not be possible, which not only affects the patient's nutrient intake and drug treatment effect, but also may cause the patient's condition to fluctuate, prolong hospitalization time and increase treatment cost.

[0004] At the same time, due to its small diameter and complex internal structure, the blocked part of the jejunum tube is often difficult to dredge. Traditional dredging methods, such as using a syringe to flush, are difficult to effectively remove the blockage, and improper operation during dredging may further damage the jejunum tube and exacerbate the problem.

[0054] A jejunal tube blocking and dredging device is described in detail below with reference to the drawings.

[0055] Referring to Figures 1 to 6 As shown in the drawings, the jejunal tube blocking and dredging device provided by the embodiments of the present application comprises a tee joint 10, a guide core 20, a vibrating handle 30 and a locking piece 32.

[0056] The tee joint comprises a first connecting head 11, a second connecting head 12 and a third connecting head 13, the first connecting head 11 is adapted to connect the end of the jejunal tube 40, the second connecting head 12 is adapted to connect the negative pressure device, and the third connecting head and the first connecting head are on the same axis; wherein the first connecting head 11 and the second connecting head 12 are both luer interface standards for easy connection.

[0057] One end of the guide core 20 is provided through the third connecting head and the first connecting head into the jejunal tube 40; the guide core 20 is made of a material that can be bent and deformed.

[0058] The vibration handle 30 is provided with a socket 31 at one end, and the other end of the guide core 20 is detachably inserted into the socket 31, so that the guide core 20 is driven to vibrate by the vibration handle 30. Advantageously, the vibration handle 30 can include an outer shell and an inner shell, and a vibration motor is arranged in the inner shell to generate vibration. The guide core 20 is inserted into the inner shell, and the vibration generated by the vibration motor is transmitted to the guide core 20 to make it vibrate, thereby assisting in unblocking the blocked place. The outer shell and the inner shell are connected in an elastic shock-absorbing manner to reduce the transmission of the vibration effect of the inner shell, facilitating the holding of medical staff. Control buttons can be arranged on the outer shell to control the vibration frequency of the vibration motor.

[0059] The locking member 32 is arranged at the front end of the vibration handle 30, and is used to fix the other end of the guide core 20 in the socket 31.

[0060] Based on the above, through the physical penetration of the guide core 20, the high-frequency vibration of the vibration handle 30 and the synchronous suction of the negative pressure device, a "unblocking-loosening-discharging" synergistic mechanism is formed, which effectively disintegrates and removes the blockage in the jejunum tube 40, and significantly improves the unblocking success rate. It can be unblocked without removing the jejunum tube 40, avoiding secondary infection, mucosal damage and other complications caused by pipe operation, reducing the pain and medical risk of patients. The device is suitable for jejunum tube 40 blockage caused by different reasons, such as nutrient liquid precipitation, drug residue, patient secretion, etc., and has wide applicability. The jejunum tube 40 blockage unblocking device of the present application realizes efficient, safe and convenient unblocking effect through innovative design and function integration, and significantly improves the clinical use value of the jejunum tube 40 and the treatment experience of patients.

[0061] Preferably, in an embodiment of the present application, the locking member 32 includes a plurality of locking portions 321 and a locking ring 322.

[0062] A plurality of the locking portions 321 are arranged at the front end of the vibration handle 30 and are distributed along the circumference of the socket 31.

[0063] The locking ring 322 is simultaneously sleeved on the outer surfaces of the plurality of locking portions 321 and is in threaded connection with the surfaces of the plurality of locking portions 321, so as to simultaneously drive the plurality of locking portions 321 to move close to the axis of the locking ring 322, thereby clamping the guide core 20 inserted into the socket 31.

[0064] Therefore, the plurality of locking portions 321 are circumferentially spaced apart along the socket 31, which can uniformly apply clamping force to the guide core 20, ensure that the guide core 20 does not loosen or shift during high-frequency vibration driven by the vibration handle 30, effectively ensure stable transmission of vibration energy, and improve the dredging effect. The locking ring 322 is threadedly connected with the plurality of locking portions 321, and the plurality of locking portions 321 can be driven to move closer to the axis of the locking ring 322 by rotating the locking ring 322, so that the clamping operation is more convenient and efficient, and the clamping force is uniform and controllable.

[0065] Meanwhile, since the locking ring 322 can drive the plurality of locking portions 321 to flexibly adjust the clamping position, the locking member 32 can adapt to guide cores 20 of different diameters and shapes, improving the versatility and compatibility of the device.

[0066] Preferably, in an embodiment of the utility model, the thickness of the plurality of locking portions 321 gradually increases from the end connected with the vibration handle 30 to the end away from the vibration handle 30.

[0067] Therefore, the thickness of the locking portion 321 gradually increases from the end connected with the vibration handle 30 to the end away from the vibration handle 30, so that the clamping force of the locking portion 321 on the guide core 20 presents a progressive distribution under the driving of the locking ring 322. The clamping force can be more effectively dispersed to avoid local stress concentration, thereby enhancing the clamping stability of the guide core 20 and ensuring that the guide core 20 does not loosen or shift during high-frequency vibration.

[0068] Meanwhile, the design of gradually changing thickness enables the locking portion 321 to more flexibly adapt to guide cores 20 of different diameters and shapes when clamping the guide core 20. For thinner guide cores 20, the thicker part of the locking portion 321 can provide more accurate clamping; for thicker guide cores 20, the thinner part of the locking portion 321 can provide greater clamping force, thereby improving the adaptability and compatibility of the device.

[0069] Preferably, in an embodiment of the utility model, the guide core 20 is provided with a liquid injection channel 21 in the middle, the liquid injection channel 21 extends along the length direction of the guide core 20, and the side surface of the guide core 20 is provided with a plurality of first liquid outlets 22.

[0070] Therefore, the liquid injection channel 21 can accurately deliver drugs (such as thrombolytic agents and antibiotics) or lubricants to the blocked part of the jejunum tube 40, and these drugs or lubricants are uniformly released around the blockage through the first liquid outlets 22, which can more effectively soften and dissolve the blockage or reduce its adhesion, thereby significantly improving the dredging efficiency.

[0071] Preferably, in an embodiment of the utility model, the front end of the guide core 20 is provided with a crushing part 23, and the crushing part 23 is in the shape of a cross.

[0072] In this way, the design of the cross-shaped crushing part 23 enables the front end of the guide core 20 to cut and crush the blockage from multiple directions when the guide core 20 is inserted into the blockage, effectively disintegrating stubborn blockages and improving the unblocking efficiency.

[0073] Preferably, in an embodiment of the utility model, the middle part of the crushing part is provided with a second liquid outlet hole, and the second liquid outlet hole is in communication with the liquid injection channel 21.

[0074] In this way, the second liquid outlet hole is located in the middle part of the crushing part, which can directly spray the flushing liquid (such as normal saline or drug solution) in the liquid injection channel 21 to the area after the crushing of the blockage, effectively removing the residual debris and dissolved substances, and preventing secondary blockage.

[0075] Preferably, in an embodiment of the utility model, the front end face and the rear end face of the crushing part 23 are formed into an arc-shaped transition surface.

[0076] In this way, the arc-shaped transition surface makes the contact between the front end face and the pipe wall of the crushing part 23 more smooth when the guide core 20 is inserted into the jejunum tube 40, reduces the insertion resistance caused by the edges or abrupt structures, and enables the guide core 20 to pass through the narrow or curved lumen more smoothly.

[0077] Preferably, in an embodiment of the utility model, a plurality of scale lines 25 are arranged on the guide core 20, and the plurality of scale lines 25 are distributed along the length direction of the guide core.

[0078] In this way, the scale lines 25 can intuitively display the depth of the guide core 20 inserted into the jejunum tube 40, help the medical staff to accurately control the insertion position of the guide core 20, and avoid the poor unblocking effect or damage to the pipe wall caused by the insertion of the guide core 20 too deep or too shallow. Through the scale lines 25, the medical staff can roughly judge the position of the blockage in the jejunum tube 40, which provides an important reference for the subsequent unblocking operation.

[0079] In the description of the present specification, the description referring to the terms "one embodiment", "some embodiments", "an example", "a specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application.
