Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a disposable endoscope atomization drug delivery tube. Background Art

[0002] Nebulizers usually convert liquid into micron-sized liquid particles. During clinical endoscopic treatment, it is usually necessary to use atomization to evenly distribute the injected drug liquid, thereby improving the uniformity of drug binding to related tissues (such as bronchial mucosa or gastrointestinal mucosa) and minimizing the impact damage to tissues that may be caused by traditional direct injection.

[0003] The fluid input by the nebulizer may include liquids used for human treatment or recovery. Current nebulizers allow patients to administer drugs by inhalation. The liquid is broken down into aerosols of tiny particles or droplets, and patients using the medicine can obtain more efficient inhalation and absorption.

[0004] However, during the inhalation administration process, it is difficult for all drugs to reach the lesion, resulting in unnecessary loss. Moreover, before the drug enters the lesion, due to its own side effects, it will cause damage to the ducts and organs along the way, posing a potential safety risk.

[0005] The position of the catheter during clinical use is difficult to determine, and it is not easy to observe its entry into the lesion, so accurate drug delivery cannot be guaranteed. In addition, the catheter handshake is not conducive to the operator's operation. During the drug injection process, the operator needs to fix the nebulizer catheter and then administer the drug, which increases the difficulty of the operator's operation, and increases the operation time and the risk of complications.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] See also Figures 1 to 5 , Figure 1 It is a schematic diagram of the structure of the disposable endoscopic atomization drug delivery tube of the utility model, which includes a handle 1, a catheter 2 and a nozzle 3. The handle 1 and the nozzle 3 are respectively connected to the two ends of the catheter 2, and the handle 1 is connected to an external injection device. A developing ring 4 is sleeved on the catheter 2. The handle 1 is used for the user to hold, and the handle 1 is connected to the external injection device. The injection device can be a syringe filled with liquid medicine. The catheter 2 is used to transmit the liquid medicine into the human body, and the nozzle 3 is used to form the liquid medicine into a spray, so that the liquid medicine directly reaches the lesion, and the patient using the medicine can get more efficient inhalation and absorption. In order to facilitate the observation of the position of the nozzle 3 in the human body, the present application sets a developing ring 4 on the catheter 2, and the developing ring 4 has a developing function under an imaging device such as an X-ray machine, so that the user can see the position of the nozzle 3 in the human body and confirm whether it reaches the lesion position, thereby accurately administering the medicine.

[0028] For ease of description and understanding, the distal end in this application is the end close to the patient's lesion, and the proximal end is the operator's operating end. When the disposable endoscopic atomization drug delivery tube is in use, the handle 1 is the operating end, so it is the proximal end relative to the nozzle 3, and the nozzle 3 is close to the patient's lesion, so it is the distal end relative to the handle 1.

[0029] The catheter 2 in the present application has a relatively thin diameter and can be used to deliver precise atomized drug to areas that are inaccessible to endoscopes. Through targeted atomized drug delivery, the drug can act on the patient's affected area faster and more accurately, avoiding drug residue in the oral cavity and nasal cavity, thereby reducing damage to the patient's body.

[0030] In the present application, the developing ring 4 is arranged on the end of the conduit 2 close to the nozzle 3, that is, the distal end of the conduit 2, which is more convenient for indicating the position of the nozzle 3.

[0031] In the present application, the number of the developing ring 4 can be single or multiple. In one embodiment, the number of the developing ring 4 is one, which is arranged on the catheter 2 near the nozzle 3, and is developed under the imaging device to indicate the position of the nozzle 3 in the human body.

[0032] In another embodiment, the number of the developing rings 4 is three, and the developing rings 4 include a first developing ring 41, a second developing ring 42, and a third developing ring 43, and the first developing ring 41, the second developing ring 42, and the third developing ring 43 are arranged in sequence from near to far from the far end of the catheter 2. The first developing ring 41, the second developing ring 42, and the third developing ring 43 form three markers in the extension direction of the catheter 2, which can play a better indicating role than a single developing ring 43, and at the same time, when a single developing ring 43 is damaged or cannot function due to other accidents, the other developing rings 43 can still function.

[0033] In the present application, the distance between the first developing ring 41 and the distal end of the catheter 2 is any value between 0.5-2mm, the distance between the second developing ring 42 and the first developing ring 41 is any value between 4-6mm, and the distance between the third developing ring 43 and the second developing ring 42 is any value between 4-6mm. In one embodiment, the distance between the first developing ring 41 and the distal end of the catheter 2 is 1mm, the distance between the second developing ring 42 and the first developing ring 41 is 5mm, and the distance between the third developing ring 43 and the second developing ring 42 is also 5mm. The first developing ring 41 is closer to the distal end of the catheter 2, and the position of the nozzle 3 can be determined by observing the position of the first developing ring 41 at the farthest end. The second developing ring 42 and the second developing ring 42 serve as markers, allowing the operator to better observe the moving distance of the disposable endoscope atomization drug delivery tube in the human body.

[0034] The material of the developing ring 4 in the present application is titanium or platinum-iridium, and it has a developing function under imaging equipment such as an X-ray machine, so that the position of the catheter 2 and the nozzle 3 in the human body can be clearly seen, and whether they have reached the lesion position can be confirmed, providing support for precise drug delivery.

[0035] In the present application, the handle 1 includes a Luer connector 11, the distal end of the Luer connector 11 is connected to the proximal end of the catheter 2, and the proximal end of the Luer connector 11 is connected to an external injection device, which can be a syringe containing a liquid medicine to be injected into the human body.

[0036] See also Figure 4 In the present application, the handle 1 also includes a finger ring 12, which is in the shape of a circular ring. The user can insert his finger into the finger ring 12 and firmly grasp the handle 1, so as to better fix the atomization catheter, making it more convenient and labor-saving when injecting liquid, and ensuring that the nozzle 3 can always be aimed at the lesion site without deviation, thereby reducing the difficulty of the operation, reducing the operation time, and reducing the risk of complications.

[0037] The number of finger rings 12 in this application can be one or two. When the number of finger rings 12 is one, please refer to Figure 5 In this case, the finger ring 12 is arranged on the side of the Luer connector 11, and the operator's finger is inserted into it during use to hold the handle 1 tightly. Of course, the number of the finger ring 12 can also be set to two, see Figure 1 The two finger rings 12 are symmetrically distributed on both sides of the Luer connector 11. At this time, both sides of the Luer connector 11 can be stressed, making it more balanced when used.

[0038] In the present application, the nozzle 3 is fixed in the conduit 2, and the distal end is exposed from the conduit 2. The nozzle 3 can be bonded to the inner wall of the conduit 2, or fixed by interference fit. Figure 3 The nozzle 3 is a cylinder, and a plurality of diversion holes 31 are provided along the axial direction. The liquid flowing to the nozzle 3 through the conduit 2 will quickly pass through the diversion holes 31, and then the liquid will be diverted into liquid particles of 5 microns to 100 microns, that is, forming a mist state. The diameter of the diversion hole 31 is positively correlated with the size of the liquid particles formed after diversion. The diversion holes 31 of different diameters can be set according to the use requirements so as to be suitable for different occasions.

[0039] During clinical use of the disposable endoscopic atomization drug delivery tube of the present application, the operator puts the treatment or recovery liquid into a syringe or other injection device, then connects the syringe to the proximal end of the Luer connector 11, and then injects the liquid by pressing or other means. After the liquid enters the catheter 2, due to the effect of pressure, the liquid will quickly pass through the diversion hole 31 on the nozzle 3, and then the liquid will be diverted into liquid particles of 5 microns to 100 microns, that is, mist state, thereby achieving targeted atomization drug delivery, and the drug effect acts on the patient's affected area faster and more accurately, avoiding the drug liquid from remaining in the oral cavity and nasal cavity, and reducing damage to the patient's body.

[0040] The method of using the disposable endoscopic atomization drug delivery tube of the present application is: select a model and specification suitable for the patient, take out the product from the inner packaging bag, insert it into the working channel of the endoscope, make the distal end of the catheter reach the lesion location under the guidance of the developing ring, load the treatment or recovery liquid into the syringe, then connect the syringe to the Luer connector, send the liquid into the catheter, and the liquid is in a mist state when it flows out of the nozzle, thereby realizing targeted atomization drug delivery.

[0041] When the disposable endoscopic atomization drug delivery tube of the utility model is used, a developing ring is arranged on the atomization catheter. When the atomization drug delivery tube enters the body, the distal end position of the catheter can be observed by an imaging device to determine whether it has reached the lesion position, thereby achieving targeted and precise drug delivery, so that the patient can receive better treatment.

[0042] The above description is only an implementation method of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present utility model.
