Description

Technical Field

[0001] The invention relates to the technical field of nursing packages, and more particularly to a pain-relieving and disinfecting nursing package for venipuncture. Background Art

[0002] Venipuncture is a common medical procedure, usually used to collect blood samples, infusion or injection of drugs. The current steps of venipuncture are to first determine the punctured vein, then select a suitable disinfectant to apply to the puncture site and the surrounding area, wait for a period of time to ensure that the iodine tincture is fully dried and effective, and finally the medical staff performs the venipuncture.

[0003] Patients will experience sharp pain during intravenous puncture. Although this is related to the specifications of the puncture needle, the puncture site, and the patient's pain tolerance, the pain is generally more obvious. The pain often causes fear in patients and affects their compliance. Children, in particular, cry and struggle during intravenous puncture due to unbearable pain and psychological fear, which only causes fear to spread to other roommates, making it inconvenient for medical workers to carry out medical operations and affecting clinical diagnosis and treatment.

[0004] In order to reduce the pain patients feel during venipuncture and enable medical care to be carried out more effectively, Chinese patent publication number CN106074849B discloses a vasodilator, analgesic and anti-inflammatory patch for arteriovenous puncture. The patch includes an application body, which includes an outer layer, a middle layer and an inner layer. Isolation layers are provided between the outer layer and the middle layer, and between the middle layer and the inner layer. The outer layer is a heating layer, the middle layer is a traditional Chinese medicine analgesic and anti-inflammatory layer, and the inner layer is a painless anesthesia layer.

[0005] The above-mentioned analgesic and anti-inflammatory patch consists of three layers: an outer layer - a heating layer, a middle layer - a traditional Chinese medicine analgesic and anti-inflammatory layer, and an inner layer - a painless anesthetic layer. The function of the heating layer is to increase the temperature of the back of the hand and dilate blood vessels. The function of the traditional Chinese medicine analgesic and anti-inflammatory layer is to relieve pain and reduce inflammation. The function of the painless anesthetic layer is local surface anesthesia. When used during arteriovenous injection puncture, it can dilate and fill blood vessels to achieve the effect of analgesia and anti-inflammatory. However, the analgesic and anti-inflammatory patch needs to go through two steps during use: application and removal. When applying, it is necessary to ensure that the position is fixed to prevent the painless anesthetic layer from deviating from the puncture site, causing the patient to be unable to use the time interval of waiting for the drug to be absorbed to perform other examinations in advance. The application and removal of the analgesic and anti-inflammatory patch will increase the operation steps and complexity of venous puncture, especially in emergency situations. The inconvenience of operation will affect efficiency. At the same time, for people with sensitive skin, removing the analgesic and anti-inflammatory patch can easily cause discomfort to the patient. In addition, the analgesic and anti-inflammatory patch cannot help nurses disinfect the area to be punctured before venous puncture. Summary of the Invention

[0006] In view of the above situation, in order to overcome the problem that the above-mentioned method of using analgesic and anti-inflammatory patches to reduce the pain felt by patients during intravenous puncture has the problem that the analgesic and anti-inflammatory patches are easy to deviate from the puncture site, and the application and removal will increase the operation steps and complexity of intravenous puncture, and it is easy to cause discomfort to patients when removed. In addition, it cannot help disinfect before intravenous puncture, the purpose of the present utility model is to provide a patient-friendly examination package that allows patients to conduct other examinations in advance during the time interval of waiting for drug absorption, ensuring the rational use of time, and without the need to go through the application and removal steps, making the operation simple, the efficiency of intravenous puncture is not affected, and it is also applicable to people with sensitive skin. At the same time, it can also be used for an analgesic and disinfection care package for disinfection before intravenous puncture.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of simplifying the description, and do not indicate or imply that the directions are specific directions that must be possessed, specific direction structures and operations, and therefore should not be understood as limiting the present invention.

[0029] like Figures 1 to 4As shown, the utility model relates to a pain-relieving and disinfecting nursing package for intravenous puncture, which includes a sealed bag 1, a lidocaine cotton swab 2 and an iodine tincture cotton swab 3, wherein the interior of the sealed bag 1 has a storage cavity 101, the interior of the storage cavity 101 is sterilized by ethylene oxide, and an access port 102 is opened on the outer wall of the sealed bag 1, the access port 102 can be located on the front, back or other positions of the sealed bag 1, and there is no special restriction. The access port 102 is connected to the storage cavity 101, and the storage cavity 101 is connected to the external space through the access port 102. The number of the storage cavities 101 corresponds to the lidocaine cotton swab 2 and the iodine tincture cotton swab 3. The lidocaine cotton swab 2 and the iodine tincture cotton swab 3 are placed in the storage cavity 101 respectively, and the lidocaine cotton swab 2 and the iodine tincture cotton swab 3 are stored in the storage cavity 101. Both the iodine swab 2 and the iodine swab 3 are disposable emergency cotton swabs. They have the same structure as the common disposable emergency cotton swabs on the market. Taking the iodine swab 3 as an example, there is iodine swab solution inside it. When one end is broken, the iodine swab solution flows to the outside. After the other end of the cotton swab fully absorbs the iodine swab solution, it can be applied to the part required for venous puncture for disinfection. Similarly, the lidocaine cotton swab 2 has lidocaine solution inside. After one end is broken, the lidocaine solution flows to the outside. The other end of the cotton swab fully absorbs the outflowing lidocaine solution. By repeatedly scraping the venous puncture site, the lidocaine solution can be applied to the part required for venous puncture. In the actual venous puncture process, first use the lidocaine cotton swab 2 to apply the lidocaine solution to the part required for venous puncture. The lidocaine solution is fully dried and absorbed, and then the iodine tincture cotton swab 3 is used to perform conventional iodine disinfection on the venous puncture site, and finally the venous puncture is performed. The utility model is provided with a lidocaine cotton swab 2 and an iodine tincture cotton swab 3 in the analgesic disinfection nursing package for venous puncture. During venous puncture, the lidocaine cotton swab 2 and the iodine tincture cotton swab 3 can respectively apply the lidocaine solution and the iodine tincture solution to the required venous puncture site to perform analgesic and disinfection operations. Since lidocaine is a local anesthetic drug that can block nerve conduction, applying the coated lidocaine solution to the puncture site before venous puncture can effectively alleviate the pain caused by the puncture, thereby reducing anxiety and fear during venous puncture, avoiding compliance being affected, and especially helping to alleviate children's pain during venous puncture. The crying and struggling during venipuncture can help medical staff to better carry out clinical diagnosis and treatment. Compared with the method of using analgesic and anti-inflammatory patches to reduce the pain suffered by patients during venipuncture, the application and removal steps are simplified, which is conducive to the simplification of venipuncture operations and the improvement of efficiency. For people with sensitive skin, it can also avoid the discomfort caused by removing the analgesic and anti-inflammatory patches. At the same time, the lidocaine solution will remain in the applied position after application, solving the problem of easy movement of the analgesic and anti-inflammatory patches, so that patients can use the time interval of waiting for drug absorption to carry out other examinations in advance, realizing the rational use of time. In addition, during the operation, medical staff do not need to carry drug containers containing lidocaine and iodine tincture, thereby reducing the operational burden of venipuncture.There is no need to dip lidocaine solution and iodine solution from the container containing lidocaine and iodine, so aseptic operation is achieved.

[0030] like Figure 1 、 Figure 2 and Figure 4 As shown, a tear strip 4 is provided in the access port 102, which covers the access port 102 and is connected to the sealed bag 1 around the access port 102, and an easy-tear line 103 is formed between the tear strip 4 and the sealed bag 1. The easy-tear line 103 is a weakening line arranged along the length direction of the access port 102. Medical staff can tear the tear strip 4 by controlling the tear strip 4 to pull along the length direction of the access port 102, thereby opening the access port 102. The entire process does not require the use of scissors or other tools, thereby simplifying the process of venipuncture, reducing the burden on medical staff, and improving the efficiency of venipuncture.

[0031] like Figures 2 to 4 As shown, the storage cavity 101 includes a first storage cavity 101a and a second storage cavity 101b, the access port 102 includes a first access port 102a and a second access port 102b, the tear strip 4 includes a first tear strip 401 and a first tear strip 402, the first access port 102a corresponds to the first storage cavity 101a, that is, the first access port 102a is equal to the first storage cavity 101a, the second storage cavity 101b shares a second access port 102b, that is, the second access port 102b has only one, the first tear strip 401 is provided in the first access port 102a, the first tear strip 402 is provided in the second access port 102b, the lidocaine cotton swab 2 is placed It is placed in the first receiving chamber 101a, and the iodine-containing cotton swab 3 is placed in the second receiving chamber 101b. Based on the fact that the analgesic operation and the disinfection operation are two independent steps during the intravenous puncture process, the above-mentioned arrangement requires two tearing actions to open the first receiving chamber 101a and the second receiving chamber 101b. The first tear strip 401 and the first tear strip 402 correspondingly arranged in the first access port 102a and the second access port 102b are removed, thereby preventing the second receiving chamber 101b containing the iodine-containing cotton swab 3 from being opened when medical staff need to perform analgesic operation, avoiding bacteria from sticking to the iodine-containing cotton swab 3 during the analgesic operation and causing contamination, thereby achieving aseptic operation.

[0032] like Figure 1 and Figure 3 As shown, the outer wall of the sealed bag 1 has a first tear mark 104 corresponding to the first tear strip 401, and a second tear mark 105 corresponding to the first tear strip 402. The first tear mark 104 and the second tear mark 105 can be numbers or letters, or other indicators that can reflect the tearing order of the first tear strip 401 and the first tear strip 402, so as to facilitate medical staff to quickly determine the opening order of the first storage cavity 101a and the second storage cavity 101b, thereby improving the efficiency of venipuncture.

[0033] like Figure 4 As shown, the number of lidocaine cotton swabs 2 is one, the number of iodine swabs 3 is two, the corresponding number of first storage cavities 101a is one, and the number of second storage cavities 101b is two. By equipping two iodine swabs 3, the area where the patient needs to be punctured is disinfected twice before intravenous puncture, so that the disinfection operation complies with the provisions of medical standards and clinical practice guidelines, ensuring the maximization of the disinfection effect and reducing the risk of infection.

[0034] Furthermore, the sealed bag 1 is made of a light-proof material. Since the disinfection effect of the iodine solution of the iodine cotton swab 3 depends on the activity of its iodine component, and the iodine component is sensitive to light, it is easy to decompose when exposed to light, thereby reducing its disinfection effect. The above setting can ensure that the iodine cotton swab 3 is stored in the dark, thereby maintaining the stability of the iodine solution, extending its validity period, and maintaining its disinfection effect.

[0035] Furthermore, the width of each storage cavity 101 of the sealed bag 1 is 2.5 cm, thereby reducing the overall size of the sealed bag 1 while providing sufficient storage space for the lidocaine cotton swab 2 and the iodine cotton swab 3, reducing the space occupied, and making the nursing bag of the present invention more convenient for medical staff to carry during venipuncture.

[0036] like Figure 5 As shown, the lidocaine swab 2 includes a first cotton swab tube 201, a first medical absorbent cotton 202, and a first medical film 203. The first medical absorbent cotton 202 is disposed at the lower end of the first cotton swab tube 201, and the first medical film 203 covers the joint between the first medical absorbent cotton 202 and the first cotton swab tube 201. Lidocaine solution is injected into the first cotton swab tube 201, and a first break line 201a is defined at the upper end of the first cotton swab tube 201. When the lidocaine solution is to be applied to the puncture site, the first cotton swab tube 201 is broken along the first break line 201a to connect the first cotton swab tube 201 to the external space. At this time, an air pressure difference is formed between the atmospheric pressure and the interior of the first cotton swab tube 201. Simultaneously, under the capillary action of the first medical absorbent cotton 202, the lidocaine solution can penetrate downward into the first medical absorbent cotton 202. Once fully absorbed, the lidocaine solution can be applied to the desired area for intravenous puncture to provide analgesia.

[0037] like Figure 6As shown, the iodine swab 3 includes a second cotton swab tube 301, a second medical absorbent cotton 302 and a second medical film 303. The second medical absorbent cotton 302 is arranged at the lower end of the second cotton swab tube 301, and the second medical film 303 is covered on the docking position between the second medical absorbent cotton 302 and the second cotton swab tube 301. The second cotton swab tube 301 is injected with iodine swab solution, and the upper end of the second cotton swab tube 301 has a second break indicator line. Consistent with the lidocaine cotton swab 2, when the iodine swab solution is to be applied to the puncture site, the second cotton swab tube 301 is broken along the second break line 301a to connect the second cotton swab tube 301 to the external space. At this time, an air pressure difference is formed between the atmospheric pressure and the interior of the second cotton swab tube 301. At the same time, under the capillary action of the second medical absorbent cotton 302, the iodine swab solution can penetrate downward into the second medical absorbent cotton 302. After being fully absorbed, it can be applied to the area required for intravenous puncture for disinfection.

[0038] Combine Figures 1 to 6 The original intention of the design of the analgesic and disinfectant nursing package for intravenous puncture of the present invention is to relieve the pain caused by intravenous puncture to the patient. When in use, according to the steps of first relieving pain and then disinfecting, the medical staff controls the first tear strip 401 to pull the tear strip 4 along the length direction of the access port 102 to tear the tear strip 4, thereby opening the first access port 102a and exposing the first storage cavity 101a to the field of vision, and then takes out the lidocaine cotton swab 2 therefrom, and breaks the first cotton swab tube 201 along the first breaking line 201a at the upper end thereof, so that the first cotton swab tube 201 is connected to the external space. At this time, an air pressure difference is formed between the atmospheric pressure and the interior of the first cotton swab tube 201, and at the same time, under the capillary action of the first medical absorbent cotton 202, the lidocaine solution can penetrate downward into the first medical absorbent cotton 202, and can be applied to the required part of the intravenous puncture for analgesic operation after it is fully absorbed. After that, the lidocaine solution is removed. Because the solution is dried and absorbed, the patient can first undergo other examinations while waiting, realizing the rational use of time. After the lidocaine solution is dried and absorbed, the disinfection operation is performed. The medical staff controls the first tear strip 402 to pull the tear strip 4 along the length direction of the access port 102, thereby opening the second access port 102b, exposing the two second storage cavities 101b to the field of view at the same time. Then, the iodine swabs 3 are taken out in turn, and the second cotton swab tube 301 is broken along the second breaking line 301a to connect the second cotton swab tube 301 with the external space. At this time, an air pressure difference is formed between the atmospheric pressure and the interior of the second cotton swab tube 301. At the same time, under the capillary action of the second medical absorbent cotton 302, the iodine swab solution can penetrate downward into the second medical absorbent cotton 302. After it is fully absorbed, it can be applied to the area required for venous puncture for disinfection. After two iodine swab disinfections, venous puncture is performed.

[0039] The above embodiments and descriptions are only for explaining the principles and best embodiments of the present invention. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and improvements, which shall fall within the scope of the invention to be protected.
