Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an anesthesia tube used for anesthetizing the surface of a urethra. Background Art
[0002] In medical practice, intraurethral operations have a very wide range of applications, such as catheterization, cystoscopy, etc. These operations can solve problems such as urination and treatment of diseases for patients. However, because there are many sensory nerves on the urethral mucosa, the urethral mucosa will be strongly stimulated when performing intraurethral operations such as catheterization. Patients will feel obvious pain, distension and other discomforts, especially male patients, who are extremely afraid of intraurethral operations such as catheterization. In order to reduce the stimulation to the urethra and relieve the patient's discomfort, medical staff will apply lubricants or lidocaine creams on the catheter and ask the patient to take a deep breath, but these measures have little effect. During the process of catheterization and when the catheter is removed, the patient still feels strong discomfort. Therefore, it is urgent to use a urethral surface anesthesia tube to perform perfect surface anesthesia on the urethra before performing intraurethral operations to alleviate the patient's discomfort and reduce the patient's pain.

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0018] The following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] The utility model is an anesthesia tube for anesthetizing the surface of the urethra. Figure 1-2 , comprising a tube body 1 and an opener 2, wherein the tube body 1 is sequentially provided with a distal end, a middle end and a proximal end, and an infusion channel 3 is further provided in the tube body 1, wherein one end of the infusion channel 3 is provided at the proximal end of the tube body 1, and the other end of the infusion channel 3 extends to the distal end of the tube body 1, and the distal end of the tube body 1 is used to extend into the patient's body; the distal end of the tube body 1 is in a closed state, the opener 2 is made of a hard material, the opener 2 is arranged in the infusion channel 3, the opener 2 is fixedly arranged at the distal end of the tube body 1, and the distal end of the tube body 1 wraps the opener 2. During use, the medical staff inserts the anesthesia tube from the patient's urethral opening into the patient's urethra, and sprays the anesthetic liquid during the process of the anesthesia tube extending into the deep part of the urethra, and during the process of the anesthesia tube extending into the deep part of the urethra, the patient's urethra expands under the action of the opener 2 made of the hard material, which not only greatly reduces the difficulty of medical staff in anesthetizing the surface of the patient's urethra, but also avoids damage to the patient's urethra when expanding the patient's urethra, greatly increasing the patient's comfort. Secondly, a medicine spray port 4 is also provided at the distal end of the tube body 1, and the medicine spray port 4 is connected to the infusion channel 3. A one-way valve 5 is also provided in the medicine spray port 4. The one-way valve 5 allows the liquid to be sprayed only from the infusion channel 3 to the outside of the tube body 1, which can effectively prevent urine or medicine in the urethra from flowing into the infusion channel 3 and contaminating the anesthetic agent in the infusion channel 3.
[0020] Preferably, the one-way valve 5 is a one-way valve. The one-way valve shaped one-way valve 5 is not only simple in structure, but also can effectively prevent urine or liquid medicine in the urethra from flowing into the infusion channel 3 and contaminating the anesthetic agent in the infusion channel 3 .
[0021] In this embodiment, a drug spray port 4 connected to the infusion channel 3 is also provided in the middle of the tube body 1. The drug can be evenly administered to the entire urethra through the drug spray ports 4 at the distal and middle ends of the tube body 1, thereby anesthetizing the entire passage from the urethral entrance to the urethral exit.
[0022] In this embodiment, the opener 2 has a semi-elliptical structure, and the bottom end of the opener 2 is connected to the tube body 1. The semi-elliptical structure of the opener 2 can not only effectively expand the patient's urethra, but also reduce the discomfort of the patient during urethral expansion.
[0023] In this embodiment, the distal end of the tube body 1 is made of a soft material, such as medical silicone or medical rubber material. During use, the distal end of the tube body 1 is attached to the surface of the opener 2, so that medical staff can more easily insert the anesthesia tube into the patient's urethra, greatly reducing the difficulty of operation for medical staff. Secondly, a gap cavity 7 is formed between the distal end of the tube body and the opener, and the opener is also provided with a through hole 8 for connecting the infusion channel and the gap cavity. When the infusion channel 3 is filled with anesthetic solution, the anesthetic solution flows into the gap cavity through the through hole, and the distal end of the tube body 1 expands outward, so that the spray port 4 at the distal end of the tube body 1 is exposed, so that the medicine can be sprayed out from the spray port 4.
[0024] Preferably, the hardness of the material at the middle end and the proximal end of the tube body is higher than that of the material at the distal end of the tube body, and a slot 9 is provided at the connection between the distal end of the tube body and the middle end of the tube body. The bottom end of the opener is arranged in the slot, so when the medical staff pushes the anesthesia tube deep into the patient's urethra, the middle end of the tube body can push the opener to move.
[0025] In this embodiment, a guide wire 6 is also included. The guide wire is arranged on the inner wall of the tube body. The guide wire 6 extends into the infusion channel 3 through the proximal end of the tube body 1 and abuts against the opener 2. The guide wire 6 allows the single tube to be more easily inserted into the patient's urethra.
[0026] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
