Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an indicative thoracentesis needle. Background Technology

[0002] A thoracentesis needle is a medical instrument primarily used for the diagnosis and treatment of pleural effusion or pneumothorax. Medically, this procedure is called thoracentesis. Thoracentesis is usually performed when a patient has pleural effusion or pneumothorax, with the aim of relieving the patient's breathing difficulties or other related symptoms, and obtaining a sample for laboratory analysis to help diagnose the cause.

[0003] In existing thoracentesis techniques, especially in emergency medical scenarios such as battlefield first aid, accurate determination of the puncture site is crucial. However, traditional methods rely heavily on the doctor's personal experience and feel. This reliance not only increases the uncertainty of the procedure but can also lead to puncture site deviation, thus prolonging the operation time and reducing treatment efficiency and success rate. Furthermore, for novice doctors or in the tense and complex battlefield environment, this experience-dependent approach amplifies the operational risks.

[0004] In view of this, the inventors specifically designed an indicative thoracentesis needle, which led to this invention. Utility Model Content

[0005] The purpose of this invention is to provide an indicative thoracentesis needle. This invention is not only simple in structure and easy to determine the accuracy of the puncture position, but can also quickly relieve pneumothorax or hemothorax.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An indicative thoracentesis needle includes a puncture section, a one-way tube, a gas collecting chamber, a cylinder, a piston, a pull handle, and an indicator liquid. The upper end of the puncture section is an inclined ellipse, and the lower end of the puncture section is connected to the inlet end of the one-way tube. The outlet end of the one-way tube is connected to one end of the gas collecting chamber, and the one-way tube is used to prevent backflow of substances on the outlet side of the one-way tube. The other end of the gas collecting chamber is connected to the cylinder, and the gas collecting chamber is used to accumulate gas and form large bubbles that enter the cylinder. The piston is disposed inside the cylinder. The cylinder is entirely transparent, allowing a clear view of its interior. The pull handle is fixedly disposed on the piston on the side away from the puncture section. The indicator liquid is disposed between the one-way tube and the piston in the cylinder and the gas collecting chamber, and the indicator liquid is used to observe the bubbles overflowing from the gas collecting chamber.

[0008] Furthermore, an annular baffle is provided between the collection chamber and the cylinder body to prevent some gas from directly entering the cylinder body.

[0009] Furthermore, the blocking sheet is made of a soft and flexible material.

[0010] Furthermore, an annular force-bearing plate protrudes outward from the side of the cylinder body away from the gas collecting chamber.

[0011] Furthermore, the indicator liquid is a liquid with low density and low viscosity.

[0012] Furthermore, the length of the puncture site is 3-4 centimeters.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects:

[0014] 1. This utility model, through the combined use of components such as a gas collecting chamber, a blocking plate, and an indicator liquid, can intuitively display the flow of gas or liquid during puncture, helping doctors to more accurately determine the puncture location.

[0015] 2. The one-way tube of this utility model can effectively prevent backflow, so that the gas or liquid in the pleural cavity can only enter the gas collection chamber in one direction, and the operator can be quickly informed by the reaction of the indicator liquid, making the whole process more efficient.

[0016] 3. This utility model reduces the reliance on personal experience for novice doctors or medical staff working in complex environments, and improves the safety and reliability of operations. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Please see Figures 1 to 3A type of indicative thoracentesis needle includes a puncture section 1, a one-way tube 2, a gas collecting chamber 3, a cylinder 4, a piston 5, a pull handle 6, and an indicator liquid 7. The upper end of the puncture section 1 is an inclined ellipse, and the lower end of the puncture section 1 is connected to the inlet end of the one-way tube 2. The outlet end of the one-way tube 2 is connected to one end of the gas collecting chamber 3, and the one-way tube 2 is used to prevent backflow of substances on the outlet side of the one-way tube 2. The other end of the gas collecting chamber 3 is connected to the cylinder 4, and the gas collecting chamber 3 is used to accumulate gas and form large bubbles that enter the cylinder 4. The piston 5 is disposed inside the cylinder 4. The cylinder 4 is transparent and the interior of the cylinder 4 can be clearly seen. The pull handle 6 is fixedly disposed on the piston 5 on the side away from the puncture section 1. The indicator liquid 7 is disposed in the cylinder 4 and the gas collecting chamber 3 between the one-way tube 2 and the piston 5, and the indicator liquid 7 is used to observe the bubbles overflowing from the gas collecting chamber 3.

[0024] like Figure 3 As shown, an annular baffle plate 8 is provided between the collection chamber and the cylinder 4. The baffle plate 8 not only prevents some gas from directly entering the cylinder 4, but also gathers the gas entering the gas collection chamber 3 into large bubbles, which are easy to observe with the naked eye. When the pressure inside the large bubble increases to a certain extent, the baffle plate 8 swings towards the inside of the cylinder 4, and the large bubble enters the liquid inside the cylinder 4. The baffle plate 8 is made of soft material and can swing.

[0025] like Figure 1 As shown, a ring-shaped force plate 9 protrudes outward from the side of the cylinder body 4 away from the gas collecting chamber 3. The force plate 9 is used to provide a force-bearing part when the piston 5 is pulled outward, and the force plate 9 can be clamped between the fingers.

[0026] Preferably, the indicator liquid 7 is a liquid with low density and low viscosity, which facilitates the movement of air bubbles.

[0027] Preferably, the length of the puncture portion 1 is 3-4 cm.

[0028] The emergency treatment process of this utility model is as follows: by pulling piston 5, the gas or blood in the chest cavity can be drawn back to relieve pneumothorax or hemothorax quickly.

[0029] In addition, after precise positioning using this utility model, the components other than the puncture part 1 can be removed, and the guide wire can be inserted into the thoracic cavity from the puncture part 1. Then, the puncture part can be withdrawn and the other end of the guide wire can be placed into a closed drainage tube.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
