Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hysterosalpingography catheters, and more specifically, relates to a hysterosalpingography catheter. Background Art
[0002] Angiography catheters are key equipment for percutaneous angiography. They are long, rubber tubes whose primary function is to guide contrast agents into blood vessels, producing angiographic results. They should possess appropriate hardness, elasticity, flexibility, and torque resistance; possess excellent X-ray transparency; exhibit good shape memory, a smooth wall, high contrast performance, and minimize thrombogenicity.
[0003] Based on the above, the inventors have discovered the following problems: the current hysterosalpingography catheter generally has a single-ended tube head, while the fallopian tubes of the human uterus are a pair that form a Y-shape with the uterus and are located deep within the uterus. Therefore, when the hysterosalpingography catheter is inserted deep into the uterus, in order to allow the contrast agent to smoothly enter the fallopian tube, sufficient pressure needs to be applied so that the contrast agent fills the uterine cavity and then spreads into the fallopian tube. However, such pressure is often excessive, causing discomfort and pain to the patient and wasting the contrast agent.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a hysterosalpingography catheter is provided, in order to achieve a purpose with greater practical value. Utility Model Content
[0005] The purpose and efficacy of the hysterosalpingography catheter of the utility model are achieved by the following specific technical means:
[0006] A hysterosalpingography catheter comprises an inner tube 1, an inner tube 2, an outer tube and a sealing membrane. A pair of slide grooves are provided in the outer tube, and slide members are provided in the slide grooves. The pair of slide members are symmetrically arranged on the outer wall of the inner tube 2. The inner tube 2 is located in the outer tube. The inner tube 2 is provided with the inner tube 1 at one end. The end of the inner tube 1 away from the inner tube 2 is in a Y-shape. The inner tube 1 and the inner tube 2 are both movably arranged in the outer tube. The outer tube is provided with a sealing membrane at the end facing the Y-shaped inner tube 1.
[0007] Furthermore, an elastic member is provided at one end of the Y-shaped inner tube, and the elastic member is made of rubber.
[0008] Furthermore, the end of the inner tube 1 close to the inner tube 2 is provided with a thread, the end of the inner tube 2 facing the inner tube 1 is provided with a thread groove, and the inner tube 1 and the inner tube 2 are connected by threads.
[0009] Furthermore, one end of the inner tube 2 away from the inner tube 1 is provided with a thread.
[0010] Furthermore, a cross opening is provided on the sealing membrane.
[0011] Furthermore, the sealing membrane is made of rubber.
[0012] Furthermore, the inner tube 1, the inner tube 2 and the outer tube are all made of rubber, and the hardness of the inner tube 1, the inner tube 2 and the outer tube increases in sequence.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] The utility model adopts the Y-shaped design of the inner tube, which allows the contrast agent to be easily introduced into the fallopian tube orifice along the inner tube, so that the contrast agent can first enter the fallopian tube and then spread into the uterine cavity, thereby reducing the pressure in the uterine cavity and thus reducing the patient's discomfort.
[0015] The design of the inner tube 1 and the inner tube 2 being connected by threads allows for a simple and convenient replacement of the corresponding parts when the inner tube 1 or the inner tube 2 is damaged. The inner tube 1 can be used as a disposable item, while the inner tube 2 can be reused after cleaning and disinfection, thereby reducing waste of resources.
[0016] The end of the inner tube 2 away from the inner tube 1 is provided with a thread, so that the output end of the contrast agent extruder can be connected to the inner tube 2 thread, thereby preventing the contrast agent extruder from falling off and separating from the inner tube 2, interrupting the operator's operation and affecting the efficiency of the angiography operation;
[0017] The cross-shaped opening on the sealing membrane allows the inner tube 2 to move toward the inner tube 1, which can easily pass through the cross-shaped opening and enter the uterine cavity.
[0018] The design of the closed membrane can prevent the secretions in the uterus from clogging the inner tube 1 during the process of moving the device into the uterus, ensuring that the contrast agent can flow smoothly from the inner tube 2 and the inner tube 1 into the uterus.
[0019] Since the inner tube one, the inner tube two and the outer tube are all made of rubber, and the hardness of the inner tube one, the inner tube two and the outer tube is increased in sequence, when the outer walls of the outer tube and the inner tube one come into contact with and scratch the inner wall of the uterus, no scratches will be caused to the inner wall of the uterus. Moreover, since the inner tube two and the outer tube are made of harder rubber material, the inner tube two can move easily inside the outer tube, thereby easily pushing the inner tube one to extend out of the outer tube or retract into the outer tube.

[0032] As attached Figure 1 To the attached Figure 7 As shown:
[0033] The utility model provides a hysterosalpingography catheter, comprising an inner tube 1, an inner tube 2 5, an outer tube 3 and a closing membrane 4, wherein a pair of slide grooves 8 are provided in the outer tube 3, a slide 7 is provided in the slide groove 8, and the pair of slides 7 are symmetrically arranged on the outer wall of the inner tube 2 5, the inner tube 2 5 is located in the outer tube 3, one end of the inner tube 2 5 is provided with the inner tube 1, the end of the inner tube 1 away from the inner tube 2 5 is in a Y-shape, the inner tube 1 and the inner tube 2 5 are both movably arranged in the outer tube 3, and the end of the outer tube 3 facing the Y-shape of the inner tube 1 is provided with a closing membrane 4.
[0034] One end of the inner tube 1Y-shaped is provided with an elastic member 2, and the elastic member 2 is made of rubber;
[0035] The Y-shaped design at one end of the inner tube 1 allows the contrast agent to be easily introduced into the fallopian tube orifice along the inner tube 1, so that the contrast agent first enters the fallopian tube and then spreads into the uterine cavity, thereby reducing the pressure in the uterine cavity and thus alleviating the patient's discomfort.
[0036] Through the design of the elastic member 2, the inner tube 1 can quickly restore its original Y-shaped shape after being freed from the restraint of the outer tube 3.
[0037] The inner tube 1 is provided with a thread at one end close to the inner tube 2 5, and the inner tube 2 5 is provided with a thread groove at one end facing the inner tube 1, and the inner tube 1 and the inner tube 2 5 are connected by threads;
[0038] By designing that inner tube 1 and inner tube 2 5 are connected by threads, when inner tube 1 or inner tube 2 5 is damaged, the corresponding parts can be replaced simply and conveniently. In addition, inner tube 1 can be used as a disposable item, while inner tube 2 5 can be reused after cleaning and disinfection, thereby reducing waste of resources.
[0039] Wherein, the end of the inner tube 2 5 away from the inner tube 1 1 is provided with a thread;
[0040] By designing that the end of inner tube 2 5 away from inner tube 1 is provided with a thread, the output end of the contrast agent extruder can be threadedly connected to inner tube 2 5, preventing the contrast agent extruder from falling off and separating from inner tube 2 5, interrupting the operator's operation and affecting the efficiency of the angiography operation.
[0041] Wherein, a cross opening 9 is opened on the closing film 4;
[0042] By designing a cross opening 9 on the closing membrane 4, when the inner tube 2 5 is pushed toward the inner tube 1 1 , the inner tube 1 can be easily driven to pass through the cross opening 9 and enter the uterine cavity.
[0043] Wherein, the sealing membrane 4 is made of rubber;
[0044] The design of the sealing membrane 4 can prevent the secretions in the uterus from clogging the inner tube 1 during the process of moving the device into the uterus, thereby ensuring that the contrast agent can flow smoothly from the inner tube 2 5 and the inner tube 1 into the uterus.
[0045] Among them, the inner tube 1, the inner tube 2 5 and the outer tube 3 are all made of rubber, and the hardness of the inner tube 1, the inner tube 2 5 and the outer tube 3 increases in sequence;
[0046] Since the inner tube 1, inner tube 2 5 and outer tube 3 are all made of rubber, and the hardness of the inner tube 1, inner tube 2 5 and outer tube 3 increases in sequence, when the outer walls of the outer tube 3 and inner tube 1 come into contact with and scratch the inner wall of the uterus, no scratches will be caused to the inner wall of the uterus. Moreover, since the inner tube 2 5 and outer tube 3 are made of harder rubber material, the inner tube 2 5 can move easily inside the outer tube 3, thereby easily pushing the inner tube 1 to extend out of the outer tube 3 or retract into the outer tube 3.
[0047] The specific usage and function of this embodiment are as follows:
[0048] When using this device, first check the integrity of this device, disinfect this device before proceeding to the next step. First, use duckbill pliers to open the patient's uterine passage, extend one end of the closing membrane 4 in this device into the uterine cavity, and adjust the position of this device according to the position of the tail slider 7 of the inner tube 2 5 so that the position of one end of the Y-shaped inner tube 1 is parallel to the Y-shaped distribution of the fallopian tube. Then push the inner tube 2 5 to move into the uterine cavity, drive the inner tube 1 to pass through the closing membrane 4 and extend out of the outer tube 3. Under the action of the elastic member 2, the inner tube 1 can smoothly stretch into a Y-shaped state, and then connect the threaded end of the inner tube 2 5 to the contrast agent squeezer, so that the contrast agent can be easily introduced into the fallopian tube orifice along the pipeline of the inner tube 1, so that the contrast agent can first enter the fallopian tube and then spread to the uterine cavity, thereby reducing the pressure in the uterine cavity and thus reducing the patient's discomfort.
