Description

Technical Field

[0001] The invention relates to a medical device, in particular to a thoracoabdominal puncture kit. Background Art

[0002] Thoracocentesis is an important medical technique that uses a puncture needle or catheter to directly puncture the peritoneal cavity to extract abdominal fluid, thereby assisting doctors in diagnosing and treating diseases. In traditional abdominal puncture methods, doctors usually use a puncture needle to extract fluid directly, or first open an opening at a designated location and then insert a tube for drainage.

[0003] However, these traditional puncture and intubation processes face some challenges in actual operation. It is difficult for doctors to accurately grasp the depth during puncture or intubation, especially for novice doctors with less experience. Therefore, during the puncture or intubation process, patients are easily injured due to improper operation, such as the formation of serious complications such as pneumothorax, or the discomfort of patients is aggravated by inaccurate operation.

[0004] In addition, the traditional thoracoabdominal puncture kit mainly includes a syringe and a puncture needle. When in use, two doctors are required to operate, and the liquid repeatedly extracted by the syringe needs to be discharged into an open container each time. Once the discharged liquid contains infection, it will bring infection risks to the operator. At the same time, frequent extraction increases the risk of surgery and patient discomfort. Summary of the invention

[0005] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a thoracoabdominal puncture kit, which includes a soft indwelling drainage tube and a hard puncture needle, wherein the indwelling drainage tube has several radial through holes. The present invention adopts an indwelling needle to bring the indwelling drainage tube to a designated position to achieve drainage of the effusion, thereby avoiding the traditional method of single hole being easily blocked by precipitated substances (such as cellulose, protein, etc.) contained in thoracoabdominal exudate or transudate, resulting in obstruction of the liquid outflow tract; at the same time, the porous indwelling drainage tube can avoid organ damage caused by improper operation, thereby reducing the risk of surgery and the discomfort of the patient.

[0006] Specifically, a chest and abdominal puncture kit includes a soft indwelling drainage tube and a hard puncture needle, wherein the puncture needle penetrates the indwelling drainage tube; A depth mark is provided on the indwelling drainage tube.

[0007] Optionally, the puncture needle includes a needle handle and a puncture needle portion, and an arc-shaped blade portion is disposed at the end of the puncture needle portion.

[0008] Optionally, the indwelling drainage tube comprises an indwelling tube portion and a gripping portion, a rubber plug is provided in the gripping portion, and the puncture needle penetrates through the rubber plug and then enters the indwelling tube portion; The indwelling tube portion is provided with a plurality of radial through holes; A flow channel pipeline connected with the indwelling tube part is arranged on one side of the gripping part. A switch is arranged on the flow channel, and the switch can prevent gas from entering the chest and abdominal cavity.

[0009] Optionally, the flow channel pipeline is connected to a drainage bag via a drainage tube.

[0010] Optionally, a negative pressure ball and / or a switch is installed on the drainage tube, and the switch is a flow regulator or a stop valve.

[0011] Optionally, the thoracoabdominal puncture kit further includes a front puncture needle, the needle head of which is provided with a depth mark, and the front puncture needle can detect the depth of the effusion from the chest and abdominal wall while providing local anesthesia.

[0012] Optionally, the thoracoabdominal puncture kit also includes a sterile containing box, which is used to contain the puncture needle, the indwelling drainage tube, the front puncture needle, the drainage bag and the drainage tube with a negative pressure control and / or switch.

[0013] Optionally, the storage box contains sterile gloves, and the storage box includes a box body and a tearable film covering the upper part of the box body, or the storage box is placed in a sterile bag; the box body is provided with a plurality of snap-fit ​​cavities, and the plurality of snap-fit ​​cavities are respectively used to snap-fit ​​and accommodate the puncture needle, the indwelling drainage tube and the front puncture needle; the sharp parts of the puncture needle, the indwelling drainage tube and the front puncture needle are all provided with protective caps.

[0014] The present invention has the following advantages: 1. Reduce surgical risks and patient discomfort: By adopting the indwelling needle, the present invention can better bring the indwelling drainage tube to the designated position to achieve drainage of effusion. At the same time, both the indwelling drainage tube and the front puncture needle are provided with depth marks, which reduces the difficulty of medical staff in grasping the puncture depth during puncture, thereby effectively reducing the risk of surgery and alleviating the patient's discomfort.

[0015] 2. Improve puncture accuracy: The design of the front needle (such as a syringe) enables medical staff to more accurately judge the insertion depth during the puncture process (such as the front needle can detect and record the depth from the chest and abdominal wall to the effusion during local anesthesia). After the front needle penetrates the designated cavity, the medical staff will feel a clear sense of emptiness, which can immediately prompt the medical staff to stop puncturing and record the depth mark on the front needle, providing a reliable basis for the subsequent use of the puncture needle to bring the indwelling drainage tube with a through hole to the designated depth.

[0016] 3. Convenient collection and treatment of effusion: The indwelling drainage tube is provided with a gripping part with a flow channel. This design not only facilitates the operation of medical staff, but also enables the flow channel to be easily connected to the drainage tube and drainage bag, thereby simplifying the collection and treatment process of effusion and improving work efficiency.

DETAILED DESCRIPTION

[0020] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0021] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0022] As described in the background art, it is difficult for doctors to accurately grasp the depth during puncture or intubation, especially for novice doctors with less experience. Therefore, during the puncture or intubation process, patients are easily injured due to improper operation, such as the formation of serious complications such as pneumothorax, or the discomfort of patients is aggravated due to inaccurate operation.

[0023] In addition, traditional chest and abdominal puncture kits mainly include basic tools such as syringes and puncture needles. Although these tools can meet basic puncture and drainage needs, novice doctors are still prone to encounter the above-mentioned operational difficulties when using them due to the lack of necessary auxiliary devices or instructions, which increases the risk of surgery and the discomfort of patients.

[0024] Based on the above reasons, this embodiment provides a thoracoabdominal puncture kit, such as Figure 2-Figure 5 As shown, it at least includes a soft indwelling drainage tube 300 and a hard puncture needle 200, and the puncture needle 200 penetrates the indwelling drainage tube 300; A depth mark 305 is provided on the indwelling drainage tube.

[0025] The above technical features can better bring the indwelling catheter to the designated position to drain the effusion by adopting the indwelling needle. At the same time, the indwelling catheter with multiple through holes is provided with a depth mark, which reduces the difficulty of medical personnel in grasping the puncture depth during puncture, thereby effectively reducing the risk of surgery and alleviating the discomfort of patients.

[0026] For example, Figure 5 As shown, the puncture needle 200 includes a needle handle 202 and a puncture needle portion 201. The end of the puncture needle portion is an arc-shaped blade portion, which can smoothly bring the indwelling drainage tube into the thoracic and abdominal cavity.

[0027] During use of the above technical features, medical personnel hold the needle handle and puncture the designated position through the blade portion. The arc-shaped (preferably semicircular) blade portion can better form an incision to facilitate the insertion of an indwelling drainage tube.

[0028] In order to achieve better drainage, in one embodiment, the indwelling drainage tube 300 includes an indwelling tube portion 301 and a grip portion 302, a rubber plug 303 is provided in the grip portion, and the puncture needle penetrates the rubber plug and enters the indwelling tube portion; The indwelling tube portion 301 is provided with a plurality of radial through holes 306 (such as Figure 7 shown); A flow channel 304 communicating with the indwelling tube is provided on one side of the gripping portion 302 ; a switch is provided on the flow channel to prevent gas from entering the thoracic and abdominal cavities. The flow channel is connected to a drainage bag 500 via a drainage tube 900 .

[0029] The above technical features can achieve drainage and collection of effusion. During use, the drainage bag is connected to the pipeline through the drainage tube, wherein the drainage bag is lower than the puncture part, and the effusion in the abdominal cavity flows out from the indwelling tube part under the action of the abdominal cavity pressure, and enters the drainage bag under the action of gravity and the physical siphon principle. In order to better input liquid drugs into the chest cavity, when the effusion is terminated and drugs need to be injected into the chest and abdominal cavity, such as Figure 3 As shown, the needle of the external syringe 600 is inserted into the rubber plug into the indwelling tube, and then the liquid medicine is pushed in. The rubber plug can be a rubber plug for indwelling needles in the prior art (which can also be inserted into the needle holder without leaking liquid).

[0030] In order to better control the flow of effusion into the drainage bag, Figure 2 and Figure 3 As shown, in one embodiment, a negative pressure ball 700 and / or a switch 800 are installed on the drainage tube 900, and the switch is a flow regulator or a stop valve; illustratively, a negative pressure balloon is arranged in front of the drainage tube to assist in suctioning pleural and abdominal effusion, and a switch is installed at the rear end to prevent gas from entering the negative pressure ball, while taking into account the function of the flow regulator or the stop valve.

[0031] The switch can be used to control the flow rate or stop flow of the accumulated fluid in the drainage tube, which is convenient for sampling; and the negative pressure ball can assist the outflow of the accumulated fluid by squeezing the negative pressure ball when the pressure in the abdominal cavity is insufficient to allow the accumulated fluid to flow out.

[0032] In order to detect the insertion depth of the indwelling drainage tube, in one embodiment, the chest and abdominal puncture kit further includes a front puncture needle 400, such as Figure 6 As shown, the needle 401 of the front puncture needle 400 is provided with a depth mark. Optionally, the front puncture needle can be a syringe.

[0033] The design of the front needle enables medical staff to more accurately judge the insertion depth during the puncture process. After the front needle penetrates the designated cavity, medical staff will feel a distinct sense of emptiness, which can immediately prompt medical staff to stop puncturing and record the depth mark on the front needle, providing a reliable basis for subsequently inserting the indwelling drainage tube to the designated depth through the puncture needle.

[0034] In order to improve convenience, in one embodiment, Figure 1 As shown, the chest and abdominal puncture kit also includes a sterile container 100, which is used to accommodate the puncture needle, the indwelling drainage tube, the front puncture needle, the drainage bag, the drainage tube with negative pressure and / or switch, and other components. The container contains sterile gloves, and includes a box body and an easy-to-tear film covering the upper part of the box body, or the container is placed in a sterile bag; the box body is provided with a plurality of snap-fit ​​cavities, and the plurality of snap-fit ​​cavities are respectively used to snap-fit ​​and accommodate the puncture needle, the indwelling drainage tube, and the front puncture needle; the sharp parts of the puncture needle, the indwelling drainage tube, and the front puncture needle are all provided with protective caps.

[0035] The above technical features enable all the tools used to be cleverly contained in a storage box, saving the time of medical staff in preparing these items before the operation, improving the efficiency of surgical preparation, and also facilitating the sorting of items after the operation.

[0036] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
