Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a disposable finger sleeve for arterial blood gas puncture. Background Art

[0002] In modern medicine, blood gas analysis is a vital test method. It provides doctors with important references for diagnosis, treatment and prognosis by evaluating key physiological parameters such as acid-base balance, gas exchange and electrolyte balance in the body. The value of blood gas analysis is particularly significant in clinical scenarios such as surgical operations, acute respiratory failure and changes in the condition.

[0003] However, the premise of blood gas analysis is to obtain high-quality arterial blood samples. Arterial blood can truly reflect the body's oxidative metabolism and acid-base balance, and is therefore considered the best specimen for blood gas analysis. In actual operation, medical staff usually need to use finger touch positioning, relying on the middle finger and index finger to accurately touch and locate the patient's radial artery or femoral artery and puncture and fix it, followed by disinfection and blood collection.

[0004] However, there are many technical challenges and operational difficulties in this process. The success rate of arterial puncture technology is often affected by differences in patient body size, different strengths of arterial pulsation, and the anatomical characteristics of the close proximity of arteries, veins, and nerves. In particular, the easy sliding of arteries further increases the difficulty of puncture.

[0005] At the same time, the disinfection process before arterial puncture also has certain risks. Although medical staff will strictly follow the operating procedures to disinfect the puncture site and the middle and index fingers used for fixation, the disinfection effect often varies from person to person. If the disinfection is not thorough, it may cause exogenous infection to the patient and increase medical risks.

[0006] Although there are finger sleeve products on the market, they still have certain deficiencies in terms of ease of operation, sensitivity and disinfection effect, etc. For example, some retractable finger sleeves or three-finger sleeve designs (whose publication number is CN2139436Y) may face problems such as complex operation, slow perception and incomplete disinfection in actual applications.

[0007] In summary, the current arterial blood gas puncture technology still needs to be improved in terms of operation success rate, safety and efficiency. Therefore, in view of the above problems, the utility model proposes a new type of finger cuff for arterial blood gas puncture. Utility Model Content

[0008] In view of the problems existing in the prior art, the utility model provides a finger sleeve for arterial blood gas puncture, which aims to improve the success rate of puncture, reduce the risk of infection, and enhance the overall convenience of operation and patient comfort.

[0009] The utility model is realized in this way. A disposable finger cuff for arterial blood gas puncture is characterized in that: it comprises at least one finger cuff body with an opening at one end, the thickness of the finger belly of the finger cuff body is less than the thickness of the finger back and the fingertip, the thickness of the finger belly is not more than 0.08mm, the finger belly is provided with a sterile film; and a pulling piece is provided at the open end of the finger cuff body.

[0010] Further preferably, the surface of the fingertip is provided with a protrusion.

[0011] Further preferably, a tearing opening is provided on the opening end of the finger sleeve body.

[0012] Further preferably, a tear line is provided along the tear opening to the end of the finger sleeve body.

[0013] More preferably, the thickness of the finger back and finger tip is 0.15-0.2 mm.

[0014] More preferably, an adhesive is provided on the back side of the pulling sheet.

[0015] Further preferably, the finger sleeve body is provided with two, and the two finger sleeve bodies are formed by lifting, and are respectively a middle finger sleeve and an index finger sleeve.

[0016] Further preferably, the pulling sheet is located between the two finger sleeve bodies.

[0017] Further preferably, two pulling pieces are provided, and the two pulling pieces are respectively located on the side of the web of the finger and the side of the back of the finger.

[0018] Further preferably, two tearing openings are provided on both sides of the finger sleeve body, and the two tearing openings are arranged perpendicular to the pulling sheet.

[0019] Advantages and technical effects of the utility model: The disposable finger cuff for arterial blood gas puncture proposed by the utility model has the following significant advantages compared with the traditional finger cuff:

[0020] Improved sensitivity: Since the thickness of the finger belly of the finger cuff is designed to be smaller than the back of the finger, and the thickness of the finger belly is no more than 0.08mm, this design significantly improves the operator's tactile sensitivity. During arterial blood gas puncture, medical staff can more accurately sense the position and pulsation of the artery, thereby improving the accuracy and success rate of puncture.

[0021] Aseptic operation guarantee: The fingertip is equipped with a sterile film, which effectively reduces the risk of exogenous infection during puncture. The sterile film can ensure that the contact surface between the fingertip and the patient remains sterile before puncture, increasing the safety of the operation.

[0022] Convenience of operation: A pull tab is provided at the open end of the finger cuff body, which makes it easy for medical staff to put on and take off the finger cuff quickly and conveniently. This design not only improves work efficiency, but also reduces possible contamination during operation.

[0023] Disposable: This utility model is designed for one-time use, which effectively avoids the risk of cross infection caused by repeated use. At the same time, the one-time design also simplifies the disinfection and cleaning process, providing greater convenience for medical staff.

[0024] Enhanced comfort: Since the design of the finger cuff takes ergonomic factors into consideration, especially the ultra-thin design of the finger belly, medical staff can still maintain comfort during long-term operation, reducing the workload.

[0025] In summary, the utility model not only improves the accuracy and safety of arterial blood gas puncture through innovative design, but also significantly improves the convenience of operation and the comfort of medical staff, which is of great significance for improving the quality of medical services.

[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0036] The utility model provides a disposable finger sleeve for arterial blood gas puncture, and its implementation mode will be described in detail through the following embodiments and marked in conjunction with the accompanying drawings.

[0037] Embodiment 1:

[0038] like Figures 1 to 4 As shown, the disposable arterial blood gas puncture finger cuff in this embodiment includes at least one finger cuff body 1 with an open end. The thickness of the finger belly 2 of the finger cuff body 1 is less than that of the finger back 3 and the finger tip 30, and the thickness of the finger belly 2 is designed to be no more than 0.08mm. Such a design can significantly improve the operator's tactile sensitivity, so that medical staff can more accurately perceive the position and pulsation of the artery when performing arterial blood gas puncture, thereby improving the accuracy and success rate of puncture. The thickness of the finger back 3 is designed to be 0.15-0.2mm, which is sufficient to provide protection against accidental puncture, thereby protecting medical staff from accidental injury to a certain extent. Although this thickness cannot completely prevent puncture in extreme cases, it can effectively reduce the risk of accidental puncture in routine operations. At the same time, this thickness design will not be too thick, so as not to affect the operator's tactile sensitivity and operational flexibility. Therefore, this design not only provides protection, but also takes into account the convenience and comfort of use.

[0039] The finger web 2 is covered with a sterile film 4, which is not bonded to the finger web near the fingertip, so that when the release paper is torn off, it is pulled downward to prevent the finger cuff body from separating from the finger; the sterile film 4 can effectively reduce the risk of exogenous infection that may be caused during the puncture process, ensure that the contact surface between the finger cuff and the patient remains sterile before puncture, thereby increasing the safety of the operation.

[0040] A pulling piece 5 is provided at the open end of the finger cuff body 1, and medical personnel can wear and take off the finger cuff quickly and conveniently by pulling the piece, thereby improving work efficiency and reducing possible contamination during the operation.

[0041] Embodiment 2:

[0042] On the basis of Example 1, Figure 5 As shown, the surface of the fingertip 2 is also provided with a protrusion 6. This design brings multiple technical effects:

[0043] Enhanced touch: The design of the protrusion 6 significantly enhances the operator's touch sensitivity, allowing medical staff to more clearly perceive the position and pulsation of the artery when performing arterial blood gas puncture.

[0044] Precise positioning: These protrusions help medical staff locate the artery more accurately, thereby improving the accuracy and success rate of puncture and reducing the possibility of mispuncture or multiple punctures.

[0045] Anti-slip effect: The protrusions 6 not only enhance the touch, but also play an anti-slip role. During the puncture operation, the fingers may become slippery due to sweat, tension or other factors. These protrusions can effectively increase the friction between the fingers and the finger sleeves, preventing the finger sleeves from sliding or falling off during the operation, thereby ensuring the stability and safety of the operation.

[0046] In summary, the protrusion 6 design on the surface of the fingertip not only improves the accuracy of puncture, but also enhances the stability and safety of the operation through its anti-slip function, providing important assistance to medical staff when performing arterial blood gas puncture.

[0047] Embodiment 3:

[0048] like Figure 6 As shown, on the basis of embodiment 1 or 2, a tearing hole 7 is further provided on the open end of the finger sleeve body 1, and a tearing line 8 is provided along the tearing hole 7 to the end of the finger sleeve body 1. The tearing line is composed of intermittent holes, and can also be relatively thin and airtight. Such a design allows the finger sleeve to be easily torn and discarded through the tearing line 8 after use, ensuring the disposable property of the finger sleeve; since the finger sleeve must be discarded after use, the risk of cross infection caused by repeated use is greatly reduced, and the safety of medical operations is improved; a clear discarding method also helps the management of medical waste, thereby supporting environmental protection and cost control to a certain extent.

[0049] Embodiment 4:

[0050] like Figure 7 As shown, on the basis of Embodiments 1, 2 or 3, the back side of the pulling sheet 5 is coated with an adhesive (not shown in the figure), and the surface of the adhesive is adhered with a release paper 5-1, and the release paper 5-1 is adhered to the pulling sheet on the opening side close to the finger sleeve body, so that when the release paper is torn off, it is pulled downward to prevent the finger sleeve body from falling off the finger; this design allows the finger sleeve to be more firmly fixed on the operator's finger to prevent it from slipping during operation.

[0051] Embodiment 5:

[0052] like Figure 8As shown, based on the embodiment 1, 2, 3 or 4, the finger sleeve body 1 is provided with two, namely the middle finger sleeve 9 and the index finger sleeve 10, and the two finger sleeve bodies are integrally formed. Such a design enables the operator to use the middle finger and the index finger for positioning at the same time during puncture, further improving the accuracy of puncture. The pulling piece 5 is located between the two finger sleeve bodies, which is convenient for pulling the two finger sleeves at the same time.

[0053] Through the detailed description of the above embodiments and the illustration of the accompanying drawings, it can be seen that the design of the disposable finger sleeve for arterial blood gas puncture of the utility model fully considers the sensitivity, safety, convenience and comfort of operation. The various technical features cooperate with each other to achieve the technical effects of improving the accuracy of arterial blood gas puncture, ensuring aseptic operation, enhancing the convenience of operation, ensuring disposable use and improving the comfort of medical staff.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
