Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic puncture, in particular to an ultrasonically guided water bag. Background Art

[0002] Ultrasound-guided puncture biopsy and ultrasound-guided puncture catheterization are commonly used clinical diagnostic and treatment techniques. Tissue puncture biopsy is the gold standard for clear disease diagnosis. Ultrasound-guided puncture biopsy is a minimally invasive method for obtaining pathological specimens under real-time ultrasound guidance. It plays an important role in clinical diagnosis and treatment. It has the advantages of short operation time, accurate sampling, small trauma, no radiation, and mild pain. The needle hole is only about 1 mm on the body surface, leaving no scars, and no need for suturing, dressing changes, or suture removal. The current ultrasound-guided puncture technology still has technical defects such as unclear needle track display, especially for punctures such as pericardial puncture that are more difficult and risky. The puncture needle can easily pierce the heart, causing serious consequences of heart damage and even endangering life.

[0003] The Chinese utility model patent with the authorization announcement number CN220275671U discloses a new type of pericardial puncture ultrasound probe, including a handle, an ultrasound probe and a puncture needle. The ultrasound probe is arranged at the bottom of the handle, and also includes an adjustment component for controlling the telescopic length of the puncture needle. The puncture needle is connected to the side of the handle through the adjustment component. The new type of pericardial puncture ultrasound probe can achieve the effect of puncturing while detecting shadows, avoiding mutual interference between the ultrasound probe and the puncture needle. However, the ultrasound probe and the puncture needle are both fixed on the handle, and the angles of the ultrasound probe and the puncture needle are always the same. When the puncture angle needs to be adjusted, the detection angle of the ultrasound probe will also change, which will affect the ultrasound needle track display. In addition, the pericardial puncture path is short, and the adjustable space of the needle track is small, which is easy to puncture the heart. Utility Model Content

[0004] The purpose of the utility model is to provide an ultrasound-guided water bag to address the defects of the prior art. The ultrasound-guided water bag can be used to display the needle track more clearly, increase the displayable needle track length, provide a large needle track adjustment space, and relatively move the probe backward, thereby avoiding interference of the ultrasound probe with the puncture needle.

[0005] In order to solve the above technical problems, the utility model provides an ultrasound-guided water bag, including a transparent water bag, which is filled with ultrasound medium, so that the ultrasound probe can perform ultrasound guidance on puncture through the transparent water bag, and a plurality of sealing plugs are arranged on the transparent water bag, and the sealing plugs are used to guide the puncture needle to pass through the transparent water bag.

[0006] The utility model adopts a transparent water bag filled with ultrasonic medium. The ultrasonic probe observes the patient ultrasonically through the transparent water bag, and the puncture needle punctures through the transparent water bag, avoiding mutual interference between the ultrasonic probe and the puncture needle, making the puncture point and the puncture angle accurate while ensuring the effect of ultrasonic display, and the needle track display is clearer, which can effectively prevent the puncture needle from stabbing the heart during pericardial puncture; secondly, because the puncture needle pierces the patient's body through the transparent water bag, the length of the needle track that can be displayed is increased, and the adjustment space of the needle track is increased, which is more conducive to the operator's adjustment of the needle track. Thirdly, the sealing plug can be used as a reference point for the puncture point, and can also prevent the leakage of the ultrasonic medium when the puncture needle passes through the transparent water bag. Moreover, the transparent water bag is transparent, and the operator can accurately pierce the transparent water bag from one sealing plug, pierce the transparent water bag from another sealing plug, and then pierce the patient. In addition, the transparent water bag is a flexible structure, and the relative positions of multiple sealing plugs can be adjusted within a certain range as needed, and the adaptability is strong.

[0007] Furthermore, a plurality of the sealing plugs are arranged on two opposite sides of the transparent water bag.

[0008] The utility model can guide the puncture needle by setting two sealing plugs, and the two sealing plugs can be respectively set on the opposite sides of the transparent water bag. When the puncture angle needs to be adjusted, since the transparent water bag is a flexible structure, the relative positions of the two sealing plugs can be adjusted by directly moving one of the sealing plugs.

[0009] Furthermore, the sealing plug includes an outer sealing plug and an inner sealing plug, and the outer sealing plug and the inner sealing plug are respectively arranged on opposite sides of the transparent water bag, one end of the outer sealing plug extends out of the transparent water bag, and one end of the inner sealing plug extends into the transparent water bag, the outer sealing plug is used as the starting point for the puncture needle to pass through the transparent water bag, and the inner sealing plug is used as the end point for the puncture needle to pass through the transparent water bag.

[0010] The utility model provides an outer sealing plug and an inner sealing plug as the starting point and the end point of the puncture needle passing through the transparent water bag, respectively, so that the operator can puncture more accurately and easily. The operator can pierce the transparent water bag through the outer sealing plug extending out of the transparent water bag, and then pass through the transparent water bag through the inner sealing plug extending into the transparent water bag, which can effectively prevent the puncture needle from puncturing the transparent water bag.

[0011] Furthermore, an anti-slip pad is provided on one side of the transparent water bag where the inner sealing plug is provided.

[0012] The utility model can be attached to the chest wall of the patient by arranging the anti-skid pad, so as to prevent the transparent water bag from moving and thus affecting the puncture of the puncture needle.

[0013] Furthermore, the ultrasonic medium is physiological saline.

[0014] The ultrasonic medium of the utility model can adopt physiological saline, and the needle track can be clearly displayed.

[0015] Furthermore, the transparent water bag is provided with a water inlet and an outlet, and a sealing cover is provided on the water inlet and an outlet, and the ultrasonic medium is poured into or discharged from the transparent water bag through the water inlet and an outlet.

[0016] The utility model can change the volume of the ultrasonic medium in the transparent water bag through the water inlet and outlet, so that the deformation capacity of the transparent water bag is within an appropriate range. The more ultrasonic medium there is, the greater the tension on the surface of the transparent water bag, and the more difficult it is for the sealing plug to move. At the same time, excessive tension on the surface of the transparent water bag will also affect the complete fit of the ultrasonic probe with the transparent water bag. If air enters the water bag and affects the detection effect, it can be exhausted through the water inlet and outlet.

[0017] Furthermore, the transparent water bag is an elastic water bag.

[0018] The utility model sets the transparent water bag as an elastic water bag, so that the volume of the transparent water bag can change with the change of the volume of the ultrasonic medium.

[0019] Furthermore, a trumpet-shaped auxiliary needle insertion structure is provided on the inner sealing plug.

[0020] The utility model can guide the puncture needle to pierce the inner sealing plug through the auxiliary needle insertion structure, thereby preventing the puncture needle from piercing the transparent water bag.

[0021] The beneficial effects of the utility model are as follows: the utility model adopts a transparent water bag filled with ultrasonic medium, the ultrasonic probe observes the patient ultrasonically through the transparent water bag, and the puncture needle punctures through the transparent water bag, avoiding mutual interference between the ultrasonic probe and the puncture needle, making the puncture point and puncture angle accurate while ensuring the effect of ultrasonic display, the needle track display is clearer, and the puncture needle can effectively avoid puncturing the heart during pericardial puncture; secondly, because the puncture needle pierces the patient's body through the transparent water bag, the length of the needle track that can be displayed is increased, the adjustment space of the needle track is increased, and it is more conducive to the operator to adjust the needle track. Thirdly, the sealing plug can be used as a reference point for the puncture point, and can also prevent the leakage of ultrasonic medium when the puncture needle passes through the transparent water bag. Moreover, the transparent water bag is transparent, and the operator can accurately pierce the transparent water bag from one sealing plug, pierce the transparent water bag from another sealing plug, and then pierce the patient. In addition, the transparent water bag is a flexible structure, and the relative positions of multiple sealing plugs can be adjusted within a certain range according to needs, and the adaptability is strong.

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] like Figure 1 As shown, this embodiment provides an ultrasound-guided water bag, including an elastic transparent water bag 1, the transparent water bag 1 is provided with a water inlet and outlet 5, a sealing cover is provided on the water inlet and outlet 5, and the transparent water bag 1 is filled with or discharged with an ultrasonic medium through the water inlet and outlet 5. In this embodiment, the transparent water bag 1 is made of a plastic sound-transmitting material such as polyethylene and polyurethane. The ultrasonic medium is physiological saline.

[0027] A plurality of sealing plugs are arranged on the transparent water bag 1, and the sealing plugs are used to guide the puncture needle 6 to pass through the transparent water bag 1. The sealing plugs include an outer sealing plug 3 and an inner sealing plug 4, and the outer sealing plug 3 and the inner sealing plug 4 are arranged on opposite sides of the transparent water bag 1, respectively. One end of the outer sealing plug 3 extends out of the transparent water bag 1, and the other end of the outer sealing plug 3 is connected to the transparent water bag 1 as a whole. One end of the inner sealing plug 4 extends into the transparent water bag 1, and the other end of the inner sealing plug 4 is connected to the transparent water bag 1 as a whole. The outer sealing plug 3 is used as the starting point for the puncture needle 6 to pass through the transparent water bag 1, and the inner sealing plug 4 is used as the end point for the puncture needle 6 to pass through the transparent water bag 1. In this embodiment, one outer sealing plug 3 and one inner sealing plug 4 are each arranged, and the sealing plugs are made of plastic and rubber materials. The sealing plugs can be arranged at different positions of the transparent water bag 1 as needed.

[0028] An auxiliary needle insertion structure 8 is fixedly arranged at one end of the inner sealing plug 4 extending into the transparent water bag 1. The auxiliary needle insertion structure 8 is trumpet-shaped and made of hard plastic. The trumpet mouth of the auxiliary needle insertion structure 8 faces the outer sealing plug 3. The auxiliary needle insertion structure 8 can guide the puncture needle to penetrate the inner sealing plug 4 to prevent the puncture needle from piercing the transparent water bag 1.

[0029] The transparent water bag 1 is provided with an anti-skid pad 2 on one side of the inner sealing plug 4, and the anti-skid pad 2 can be attached to the patient's chest wall to prevent the transparent water bag 1 from moving and thus affecting the puncture of the puncture needle 6. The anti-skid pad 2 is made of medical viscose materials such as acrylic ester.

[0030] The method of using the ultrasound-guided water bag is as follows: determine the puncture point in advance, pour physiological saline into the transparent water bag 1 from the water inlet and outlet 5, use the inner sealing plug 4 as a reference point for the puncture point, put the anti-slip pad 2 of the transparent water bag 1 on the patient's chest wall and fix it, so that the inner sealing plug 4 is aligned with the puncture point. Press the ultrasonic probe 7 on the transparent water bag 1, and the puncture needle 6 is inserted into the patient's body through the outer sealing plug 3 and the inner sealing plug 4 in turn, and observe the puncture needle 6 with the ultrasonic probe 7, so that the puncture needle 6 passes through the chest wall and accurately reaches the pericardial cavity.

[0031] It is understandable that, since the puncture needle 6 punctures the human body through the transparent water bag 1, the puncture position moves backward, the length of the needle track that can be displayed is increased, the adjustment space of the needle track is increased, and it is more convenient for the operator to adjust the needle track. In addition, the ultrasonic probe 7 can find the best probe angle on the transparent water bag 1 to ensure that the needle track detected by the probe is clear, and there is almost no interference with the puncture needle 6.

[0032] In addition to pericardiocentesis, the ultrasound-guided water balloon can also be used for other ultrasound punctures.

[0033] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
