Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a protective device for an ultrasound-guided puncture probe. Background Technology

[0002] Ultrasound-guided puncture is a commonly used puncture method. With the help of an ultrasound probe, the puncture site can be accurately located, providing a guarantee for the puncture. Currently, during thoracic disc puncture, the ultrasound probe is located at the patient's ribs, and the operator holds the puncture needle to perform the puncture based on the ultrasound image. However, during the puncture, due to improper operation, the patient's thin body size, and the curvature of the ribs, the puncture needle is prone to puncturing the patient's skin and hitting the ultrasound probe, causing damage to the ultrasound probe.

[0003] Utility model patent CN203328725U discloses a novel protective film for an abdominal ultrasound probe, comprising a sheath 1 and a sealing strip 2. The sheath 1 consists of an outer sleeve and an inner sleeve, with the sealing strip 2 connected to the open end of the inner sleeve. In this utility model, the sheath 1 is made of plastic or rubber, and its shape conforms to the contact surface of the probe. The inner sleeve of the sheath 1 is slightly higher than the outer sleeve, and the inner bottom layer of the outer sleeve is coated with a coupling agent. In use, the probe is placed inside the inner sleeve of the sheath 1 and secured with the sealing strip 2. The probe contacts the patient through the coupling agent in the inner layer of the outer sleeve of the sheath 1 for diagnosis. Because the probe is protected by the sheath 1, the wear and tear on the probe is reduced. After the examination, the sheath 1 is replaced to prevent potential cross-infection. Covering the ultrasound probe with a film is a common protective method. Covering the ultrasound probe can not only isolate the patient from the ultrasound probe, but also remove the film after use and re-cover it to perform ultrasound examinations on different patients. However, if the film thickness is too low, it can only be used to separate the ultrasound probe from the patient's skin. During the guided puncture process, it does not block the puncture needle. Under ultrasound-guided puncture, after the puncture needle penetrates the skin, it will still directly act on the end face of the ultrasound probe, thereby causing damage to the ultrasound probe. Utility Model Content

[0004] The main purpose of this invention is to provide a protective device for ultrasound-guided puncture probes, which solves the problem that existing ultrasound probes are easily damaged by puncture needles that penetrate the skin during guided puncture.

[0005] To achieve the above objectives, this utility model provides a protective device for an ultrasound-guided puncture probe, comprising a protective sleeve; the protective sleeve has a hollow interior forming an installation cavity; a wrapping sleeve is provided on the installation cavity; a drawstring is provided on the wrapping sleeve; a protective cavity is provided in the inner wall of the protective sleeve; an inlet channel and an exhaust channel are respectively provided on the outer wall of the protective cavity; a first one-way valve and a second one-way valve with opposite directions are respectively provided in the inlet channel and the exhaust channel.

[0006] As a further improvement of this utility model, the mounting cavity and the protective cavity are arranged from top to bottom, with the probe located inside the mounting cavity.

[0007] As a further improvement of this utility model, the drawstring is fitted over the outside of the package and is elastic, with the width of the drawstring ranging from 3cm to 8cm.

[0008] As a further improvement of this utility model, the liquid inlet channel is provided with a liquid inlet pipe; the liquid inlet pipe is arranged along the outer wall of the protective sleeve and the wrapping sleeve; the exhaust channel is provided with an exhaust pipe; the exhaust pipe is arranged along the outer wall of the protective sleeve and the wrapping sleeve; the first one-way valve and the second one-way valve are respectively arranged in the liquid inlet pipe and the exhaust pipe.

[0009] The beneficial effects of this utility model are reflected in:

[0010] By setting up a protective cavity and injecting coupling agent, the protective cavity expands in volume, forming an isolation between the patient's skin and the ultrasound probe. The sheath is connected to the handle of the ultrasound probe by a drawstring. The ultrasound probe is located in the installation cavity filled with coupling agent, ensuring that there is no air between the ultrasound probe and the patient's skin, thus guaranteeing the normal use of the ultrasound probe. During the puncture process, the puncture needle penetrates the skin and enters the protective cavity, without directly puncturing the ultrasound probe, thus providing protection for the ultrasound probe.

[0015] 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 described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] In one embodiment, see Figure 1 The present invention relates to a protective device for an ultrasound-guided puncture probe, comprising a protective sleeve 1, the inside of which is hollow to form an installation cavity 2; a wrapping sleeve 3 is provided on the installation cavity 2, and a drawstring 4 is provided on the wrapping sleeve 3; a protective cavity 5 is provided in the inner wall of the protective sleeve 1, and an inlet channel 6 and an exhaust channel 7 are respectively provided on the outer wall of the protective cavity 5, and a first one-way valve 8 and a second one-way valve 9 in opposite directions are respectively provided in the inlet channel 6 and the exhaust channel 7.

[0017] Further, see Figure 2 The mounting cavity 2 and the protective cavity 5 are set from top to bottom, with the probe located inside the mounting cavity 2.

[0018] Preferably, the protective sleeve 1 and the wrapping sleeve 3 are non-shrinkable films.

[0019] Preferably, the opening direction of the first one-way valve 8 is towards the protective cavity 5, and the opening direction of the second one-way valve 9 is away from the protective cavity 5.

[0020] In the above setup, after the ultrasonic probe is placed into the mounting cavity 2, coupling agent is injected into the mounting cavity 2 and the protective cavity 5 respectively. The coupling agent can be drawn up with a syringe and injected into the protective cavity 5 through the liquid inlet channel 6. As the coupling agent is injected, the air in the protective cavity 5 is discharged through the exhaust channel 7 to prevent air from entering the protective cavity 5. The coupling agent in the mounting cavity 2 wraps the ultrasonic probe to prevent air from entering the mounting cavity 2. The wrapping sleeve 3 is tightened and placed on the ultrasonic probe by the drawstring 4.

[0021] Further, see Figure 1 The drawstring 4 is fitted over the outside of the package sleeve 3 and is elastic. The width of the drawstring 4 ranges from 3cm to 8cm.

[0022] Preferably, the drawstring 4 is an elastic band, the drawstring 4 is circular, and the initial inner diameter of the drawstring 4 is smaller than the outer diameter of the handle of the ultrasonic probe.

[0023] In the above setup, after the cover 3 is unfolded, it wraps around the handle of the ultrasonic probe. The head end of the ultrasonic probe is located inside the mounting cavity 2. The drawstring 4 is pulled open and enlarged before being placed on the handle of the ultrasonic probe. The cover 3 is pulled again to adjust its position, so that the protective sleeve 1 moves upward along the ultrasonic probe, making the mounting cavity 2 and the ultrasonic probe fit tightly together. The gap between the mounting cavity 2 and the ultrasonic probe is filled with coupling agent. The cover 3 is bound to the handle of the ultrasonic probe by the drawstring 4. Because the drawstring 4 has a width, the contact area between the drawstring 4 and the cover 3 is larger, resulting in a better binding effect on the cover 3.

[0024] Further, see Figure 1 The liquid inlet channel 6 is provided with a liquid inlet pipe 10, which is set along the outer wall of the protective sleeve 1 and the wrapping sleeve 3; the exhaust channel 7 is provided with an exhaust pipe 11, which is set along the outer wall of the protective sleeve 1 and the wrapping sleeve 3; the first one-way valve 8 and the second one-way valve 9 are respectively set in the liquid inlet pipe 10 and the exhaust pipe 11.

[0025] Preferably, the ends of the liquid inlet pipe 10 and the exhaust pipe 11 are flush with the end of the wrapping sleeve 3.

[0026] In the above setup, the coupling agent is injected into the protective cavity 5 through the inlet tube 10 and enters the exhaust tube 11. After the sheath 3 is secured to the handle of the ultrasound probe by the drawstring 4, the height of the inlet tube 10 and the exhaust tube 11 is higher than that of the protective cavity 5. At the same time, the inlet tube 10 and the exhaust tube 11 are filled with coupling agent. During the puncture under ultrasound guidance, since coupling agent needs to be applied between the patient's skin and the protective sheath 1, if the protective cavity 5 is punctured by the puncture needle, it will be difficult to detect the coupling agent flowing out of the protective cavity 5 in time. At this time, the level of coupling agent in the inlet tube 10 and the exhaust tube 11 can be observed. If the level of coupling agent in the inlet tube 10 and the exhaust tube 11 moves downward, it can be known that the protective cavity 5 has been punctured. At this time, the protective sheath 1 can be replaced in time. Since the protective cavity 5 is filled with coupling agent, there is a gap between the patient's skin and the ultrasound probe, and the puncture needle will not puncture the ultrasound probe.

[0027] In this embodiment, the ultrasound probe is placed in the mounting cavity 2 and filled with coupling agent. The sheath 3 is tied to the handle of the ultrasound probe using a drawstring 4 and tightened so that the sheath 3, the protective sleeve 1, and the ultrasound head fit tightly together. The gap between the ultrasound probe and the mounting cavity 2 is filled with coupling agent. Coupling agent is injected into the protective cavity 5 through the inlet tube 10, causing the air in the protective cavity 5 to be expelled and the protective cavity 5 to expand. During ultrasound-guided puncture, the outermost end face of the protective sleeve 1 contacts the patient's skin and is coated with coupling agent. The coupling agent in the protective cavity 5 is located between the ultrasound probe and the patient's skin and occupies space. During ultrasound-guided puncture, if the puncture needle penetrates the skin, the puncture needle will first pierce into the protective cavity 5 and will not directly pierce the ultrasound probe, thus providing protection for the ultrasound probe.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
